  • Video analysis on Deva HD

    Deva HD model is equipped with a Full HD camera that provides ONFIV-compliant video streams.

    Those streams are available on the entire local network through any rstp media player, so DEVA HD can easily be integrated with third-party video-analysis software to manage the different scenarios, improving the security:

    • Video surveillance
    • Abandoned object detection
    • Queue evaluation (People counter)
    • Parking Control
    • Gate transit (People counter)
    • Restricted area intrusion detection
    • Social distancing (Crowding monitoring)

    The scenario listed above can be set using the provided video-analysis software V-Track for Win10 OS or Reko for Ubuntu OS and require a compatible graphic card with memory resources, based on the number of video flows that need to be processed.


    Figure 1 – Example of Queue evaluation.

    Notes:
    V-Track and Reco are external software that requires additional licenses per video flow.

  • Speaker Preset

  • How Powersoft limiters work - Peak Limiter

    The peak limiter avoids potentially dangerous displacement of the cone (larger excursion with respect to the allowed values), and it is based only on the quantity of signal that is sent through that channel.

    Peak limiters, as well as RMS and Clip limiters, are independent from the number of parallel wired speakers: you can use the power and impedance of a single speaker or the power and impedance of the parallel circuit, the given result will be the same.

    Pushing into a peak limiter can reduce the crest factor, thus “squashing” the dynamics of the original signal. For most applications, 3 to 9 dB of gain reduction is usually suggested.

  • How Powersoft limiters work - Clip Limiter

    The Powersoft clip limiter is a “brickwall” limiter that blocks the driving signal, not allowing it to exceed the threshold. This limiter has a fixed attack time of 0.3 ms with a lookahead of 0.3 ms that allows anticipating peaks before they occur and therefore with the benefit of less distortion by not having a hard clip. Clip limiters are very fast and are the last safety tool that can be used to avoid loudspeaker damage. To achieve the best result in quality and performance, it is suggested a gain reduction between 0 and 3 dB and engage also Peak and RMS limiters.

    Limiters (basic) in ArmonìaPlus.

  • How to calculate limiter values

    To calculate Voltage thresholds, attack, and release time for the three basic limiters available in ArmonìaPlus, Powersoft has developed a tool called the Power Sharing Tool. In this tool, there is a dedicated section called “Suggested Limiters threshold” that can be used as a safe starting point while working with limiters. Simply add the loudspeaker’s AES power, and the nominal impedance and select its profile (or the way of the loudspeaker). Once these values are specified the tool will calculate and suggest a possible limiters configuration. The tool provides calculations for both Low-Z loudspeakers and Hi-Z lines (100V, 70V, and 25V)

    Remember that this is only the starting point, especially for a multi-way loudspeaker where it is always suggested to analyze the behavior of the ways with a musical or pseudo-musical signal. In this way, tonality unbalances due to wide differences in gain reduction between the transducers can be avoided.

    Powersoft Power Sharing tool limiters section.

    After this basic analysis of Powersoft limiters we can focus on two key points: the first one is that all Powersoft limiters are made to protect the loudspeaker, so it is best practice to have them always enabled. The second one concerns the sound quality and good system design: the best performances in audio quality are achieved when, as mentioned previously, RMS limiters can do the heaviest part of the job in terms of gain reduction, then Peak limiters to control transients and Clip limiters as a final safety point. By following this simple workflow, you will achieve the best audio quality from your system, ensuring its long lifespan.

  • Run ArmoníaPlus on Mac

    In this application note we will explain how to use ArmoníaPlus on your Mac through Windows virtualization software. The procedure is fundamentally the same for the various software’s in the market and for our example we will use Parallels Desktop.

  • Run ArmoníaPlus on Mac - Download & Install
    1. Parallels Desktop or other virtualization software for Windows.

  • Limiter Parameters - Threshold

    When the input signal level exceeds the threshold, the limiter starts to reduce the input gain.
    Gain is reduced of an amount equal to the overshoot of the input signal with respect to the threshold.

    The threshold value is expressed in Volt because it depends on the power of the loudspeaker and its impedance

  • Limiter Parameters - Attack time

    It is the time the limiter takes to get 70% of the total required reduction after exceeding the threshold level. In applications where we want to avoid speaker damage, the longer the attack time, the higher the risk of damaging the equipment. However, settings with a too fast attack time can generate distortions or a deep modification to the transient of the signal, especially with percussive sounds, resulting in poor perceived sound quality.

    Typically, a good compromise is to set an attack time no longer than the lowest frequency you need to protect (i.e., 1 ms for an HF driver with X-over at 1kHz octave band).

    Limiter acting on an audio signal

  • Limiter Parameters - Release Time

    It is the time that the gain takes to go from the maximum reduction to 30% of reduction. In general, the release time, must be adequate to avoid a pumping effect and protect the speaker. The release time can be set between 1 to 32 times the attack time.

  • Limiter Parameters - Soft Knee

    A soft knee slowly increases the compression ratio as the level increases, this way the changing from un-compressed to compressed sound is less audible. This value in Powersoft limiters is expressed in dB below the threshold.

  • How Powersoft limiters work - RMS Limiter

    The RMS limiter is intended to prevent burning the driver’s voice coil, while at the same time exploiting their maximum performance. The RMS limiter should not be engaged at normal working levels since a common musical signal has very high peaks, but a rather small average level.

  • Limiting, Speaker Damage and Power Compression

    The limiting process in sound reinforcement is a way to protect loudspeakers from accidental damage; therefore, limiters are a safeguard against excessive signal peaks and/or signal long-term average power. Bear in mind that limiting does not only prevent occasional damage, but it first and foremost guarantees a long loudspeaker life. Speaker limiter designers do not usually concentrate on coloring sound, but rather on speaker protection. Typical applications in the audio chain are:

    • Controlling the energy of a signal.
    • Controlling the peak levels of a signal.
    • Reducing the dynamic range of a signal.

    Remember that in sound reinforcement you are dealing with power signal (that means high voltage and currents), so the target with limiters is to protect the drivers from the two main causes of damage:

    • Over-excursion: An impulsive signal can reach the speakers and cause damage due to over-excursion of the voice coil that is driven out of the mechanical limit. This can damage the diaphragm by deforming or breaking it.
    • Over-heating: Delivering high power for too much time may lead to overheating of the voice coil copper, the coil former, the magnet, the suspensions, and the cone itself. Another effect is power compression, more noticeable in low-frequency speakers. When there is power compression there is an increase in the impedance and a decrease in power with the result of less perceived loudness!

    HealthPlus can have a maximum of 10 measurements enabled and display a maximum of 2 different ranges at a time, it’s possible to hide the measurements and delete all.

    The saved measurements refer to the last hour of use.

  • Can I view a list of Alarms?

    In Event History, we can see the date of the event, type of event: Device or Software, priority: low, medium or alarm, and the description of the event. We can also export them to a file (.xlsx), and remove them all.

    Event History

    Active Events

    In “Active Events” we can see the events and alarms that are happening in the system. Also, we can see the example of a loss in audio channels, we see exactly how many channels were lost, which input format, amplifier, and channel, so that we can be precise in solving the problem.


    Active Events

  • What can i monitor with Healthplus? Speakers

    Speakers

    In this section, it is possible to monitor the status of the speakers, which amplifier they are connected to, which output they are connected to, ways description, overall output gain, headroom, and impedance of the speaker. (Figure 3)

    Figure 3 – Speakers

    Active

    In active, we can monitor the speaker with signal, no signal (without signal), and Muted.

    Headroom

    In headroom, we could monitor:

    • Positive Headroom: This means that you still have headroom to increase the volume in case you need it.
    • Limiting: You have reached the limit of the loudspeaker! We recommend do not increase the volume more, if you need more SPL increase the number of speakers or select a more powerful loudspeaker.
    • Heavy Limit: It means that the channels are limiting more than 12 dB of gain reduction. (This could be because you have an under-sized system, increase the number of loudspeakers, or select a more powerful loudspeaker.)

    Impedance

    In this section, it is possible to monitor the speakers working within the nominal threshold range, which are inactive, and the loudspeakers at fault.

    • Within the range: It is based on the impedance entered in the speaker preset information (.spk3). If no value is entered, the result is always within the nominal range.
    • Inactive: When the amplifier is not reading the impedance, it will show the last measurement made.
    • Fault: When the measurement is out of the established nominal threshold range.

    E.g., with an 8 Ω speaker, the upper limit is 4x (32 Ω) and the lower limit is 1/2 (4 Ω), so above 32 Ω and below 4 Ω, HealthPlus will send an alarm Fault.

    The Hi-Z description appears in the X and Ottocanali Series above 400 Ω, and the T Series, Duecanali, and Quattrocanali above 100 Ω.

  • What can i monitor with Healthplus? Amplifiers

    Amplifiers

    In this section, it is possible to monitor the status of the amplifiers by name, model, serial number, temperature, and firmware. (Figure 4)

    Ready

    In the ready category, we can monitor amplifiers online, stand-by, and offline.

    TEMPERATURE

    Each amplifier model has different temperature ranges where they can work, also different points inside the amplifier where the temperature is taken to be monitored, and to simplify readings to the end customer we have opted for a new way of viewing this in percentage.

    • 0% – 100%: Is an optimal range for working.
    • 100% – 150%: Limits the outputs to reduce heat and help cooling.
    • > 150%: The amplifier could turn off to protect itself.

    Firmware

    In Firmware we can monitor the total number of amplifiers:

    • Updated: That has the latest firmware available.
    • Outdated: amplifiers that have a more recent firmware available for upgrade.
    • Not supported

    • Offline: when we lose the connection with an amplifier or when we turn it off.
    • Warning (Phase): when there is a phase loss.
    • Warning (Voltage): when an amplifier deviates from the average.
  • What is Healthplus?

    Is the new ArmoniaPlus monitoring and measurement system, which allows you to accurately monitor each amplifier, speaker, and in-and-out signals. Furthermore, you allow yourself to measure a lot of information for analysis.

    HealthPlus, replaces the software’s previous ‘Events’ tab, giving sound engineers and integrators a streamlined monitoring environment of all elements in a given sound system with improved communication, control, and reporting ensuring even better performance than ever before. HealthPlus updated display gives engineers a complete suite of system diagnostic controls to monitor the health and effectiveness of any sound system in real-time, it can be used with a touring PA or in fixed installations like cinemas, airports, theme parks, etc. In addition to input monitoring for power amplifiers, speakers, and other connected devices, the system is also capable of measuring system health indicators such as headroom, temperature, voltage, and impedance to ensure optimal performance of all elements and will automatically alert users in case of malfunctions or element failures. Engineers can also now utilize the Event History function to track uploaded programs, and user logins, and diagnose any long-term system issues. Finally, HealthPlus has improved reporting, giving users the ability to track multiple indicators at once over an hour time log period for more detailed system monitoring.

  • What can i monitor with Healthplus? Inputs

    Inputs

    In this section it is possible to monitor the inputs channels, their quantity in total and are divided into Active, Passive and Missing categories. (Figure 1)

    Active

    These are the inputs that are playing, independent of the format. We can monitor the total number of input channels for:

    • Dante / AES67
    • AES3 (Digital)
    • Analog

    Furthermore, in status, there is the possibility to ignore one or more channels so that HealthPlus does not always signal an alarm. e.g., when you mute the mixer master or between tracks using a media player.

    Passive

    These are the signals present in the backup strategy, ready to become active as needed.

    e.g., For input redundancy, when we lose a digital input and have an analog signal in the backup strategy.

    Missing

    Signals are lost since you saved the reference.


    Figure 1 – Inputs

    Save & clear reference

    With HealthPlus it is possible to monitor the number of input signals and you can also save a reference so that ArmoníaPlus sends you an alarm when this reference changes. By clicking on save the reference, (4/4), which would be the number of channels present / the number of reference channels.

    E.g., when you lose one or more input channels.  A recommended time to activate this reference is at the end of a soundcheck or at the end of an installation. (Figure 2)

  • Workspace

  • Mono-Mix Source Dante Sharing

    ArmoniaPlus 2.3 now features Mono-Mix Source Dante Sharing. This new feature addresses the use of Powersoft’s Dynamic Music Distribution system. It enables users to have more stereo sources available in designs when using 4-channel Mezzo AD models while driving 2 or more zones.

    The ability to distribute a stereo source as a Mono-Mix on Dante gives value to a system. Users can now save Dante input channels on receiving amplifiers, allowing them to have unique stereo source selections available for each zone. This benefit allows for example the use of a single Mezzo 604AD to drive for independent zones, each playing different background music sources.

    The use of this feature only applies to system designs using Mezzo AD models. The Mono-Mix Dante sharing capabilities are limited to sources that are physically patched to Mezzo AD analog inputs and shared over Dante.

    To add a Mono-Mix Source within ArmoniaPlus simply choose Design > Add and select ‘Source’ found within the upper window of the loudspeaker workspace; With the source in the workspace select it and choose ‘Analog’ as the format. Next, select ‘Mono (L+R mix)’ in the dropdown window. Now, choose ‘edit patch’ and patch left and right to inputs 1 and 2, and enable Dante sharing.

    ArmoniaPlus 2.3 now gives the user more stereo sources in designs when driving 2 or more zones using 4-channel Mezzo AD’s. Another example of Powersoft’s technologies supporting its ever-growing user base.

  • Routing Adjustments

    The ability to change between a mono, stereo or summed send within the installation skin of Armonia Plus is quick. The software allows the user simple manipulation of their systems routing with just the click of a mouse. Within this video we will explain how to adjust the routing assignments within a project while referencing an existing example named ‘Install One’.

    To access the routing assignments within ArmoníaPlus we need to select the ‘Config’ > ‘Routing’ tab found across the bottom portion of the Workspace.  Within this tab, we will find the ‘Source Format’: Mono, Stereo, and Multi-Channel. By selecting mono and choosing our ‘Zone 2’ loudspeakers we can choose if this group of loudspeakers is ‘ON’, this will allow the source to send.  we also have the option of whether it is ‘OFF’, this mutes the send.

    Let’s now select ‘Stereo’ within the ‘Source Format’ tray below. Choosing ‘Stereo’ and clicking on our point source loudspeaker within ‘Zone 1’ we can change the loudspeaker from a ‘Left’, ‘Right’ or ‘Summed Left and Right’ send.  You can notice that ‘Zone 1’ is configured as a ‘Stereo’ send with both ‘Left’ and ‘Right’ sends selected within this zone. ‘Zone 2’ and ‘Zone 3’ have been selected as a ‘Summed Left and Right’ send.  We also have the option to turn these sends ‘OFF’ just like was shown within the ‘Mono’ ‘Source Format’.

    Choosing ‘Multi Ch.’ within the ‘Source Format’ tray will allow the user to choose multiple channels for individual loudspeakers.  This routing option can be used for surround sound systems and will support a Dolby Atoms system of sixty-four channels when used in conjunction with a Dolby Atmos processor.

    ArmoníaPlus is here to help the user’s installation move quickly and efficiently. Routing within ArmoníaPlus is simple and intuitive, allowing the user confidence, knowing their system is rooted for success.

  • System List

  • What data can you see in the System List?

    The System List displays the main details of all the amplifiers making up the current Setup (either on-line or off-line). The System List is a useful tool both in live events and in maintenance environments, where multiple units have to be monitored.

    HEADER ROW

    The view is completely customizable: it is possible to select what column to show or hide. Right click on the header row and select among the following:

    • Dante Name

    • Model
    • Preset (Snapshot .pam)
    • On/Off
    • MAC Address
    • Mains
    • Scheduler
  • DYNAMIC MUSIC DISTRIBUTION

  • Views Host failover redundancy

    In case a preferred Views Host or WM Touch fails for network or hardware problems, the Dynamic Music Distribution has the Failover Redundancy, which allows the system to continue running using another View Host available on the network.

    This feature is available starting with WM Touch firmware v1.1.2.9 and Views Host v1.6.4.3.

    This feature allows seamless failover redundancy across multiple WM Touch and/or PC Views Hosts within the same system. Failover redundancy ensures that the system control will continue to run smoothly even in the case of a WM Touch or PC Views Host failing/going offline.

    Note that the new failover redundancy does not require any configuration and that the health check of devices within a Dynamic Music Distribution system is a fully automated background process, the only difference will be the IP Address of the server because the new Views Host will have a different IP address from the preferred.

  • Deploying the ArmoníaPlus project

    To have zone, source, and scene control on your project, the project needs to “Run” or be deployed first. If the project is not “Run,” the WM Touch will not have the control interface loaded and the WM Passive will only act as a VCA volume control for your amplifiers.

    To “Run” the project, you would need to make sure that your project is set up properly. If the project was not set up properly, an error will pop up when you try to run the project. To “Run” the project, click on the “Rocket” icon and then click “Run.”

    Running controls & Views

  • GPI capabilities

    Apart from controlling the system using the WM Touch, users can also configure the system to be controlled using the WM Passive wall controllers. The WM Passive wall controllers need to be connected to the “GPI” inputs of an amplifier. Do take note that not all the amplifiers come with “GPI.”

    The table below shows the amplifier models and their available “GPI” inputs.

    Table – List of GPI on Powersoft amplifiers

    Notes:

    The “GPI” signal from one amplifier can be shared over the network with another amplifier. This will enable the user to have WM Passive wall controllers controlling other amplifiers on the network.

    While some of the non-DSP+D amplifiers like the Quattrocanali feature “GPI” inputs are used for VCA control. For zone, source, and scene control, a DSP+D enabled amplifier is required.

    For Mezzo both A and AD models can have zone, source, and scene control on the “GPI” inputs.

  • Locating the GPI port

    The diagrams below show the location of the “GPI” port of each amplifier.

  • What is Dynamic Music Distribution?

    Dynamic Music Distribution offers System Integrators the ability to scale inputs and zones conveniently and efficiently with dynamic routing capabilities embedded in its amplifier platforms. This makes it simpler to share music between different zones independently from the source location and to carry control signals in an automated fashion without the need for a centralized DSP.

  • Zoning capabilities

    Dynamic Music Distribution enables the system to differentiate zones assigned to one or more amplifiers without needing a central DSP or zone mixer. Do take note that the number of zones that an amplifier can have does not always correspond to the number of outputs available on the amplifier.

    Here is a list of the various amplifiers and their zoning capability.

    Table 1 – Maximum zones available on Powersoft amplifiers.

    Notes:

    As a rule of thumb, except for Mezzo Series, all other amplifiers have ½ the number of zoning capabilities compared to their outputs.

    Dynamic Music Distribution does not support speakers linked in Spit Mode” to amplifiers, so they cannot be assigned to any zone.

  • Dante input and output capabilities

    The Dynamic Music Distribution capability of the system also enables dynamic routing. Dynamic routing enables the user to easily share their analogue or AES3 signal with other amplifiers on the network through DANTE receivers. This is made possible with the use of DANTE transmitters available on select Powersoft amplifiers.

    Some considerations need to be kept in mind on the number of simultaneous DANTE sources that one amplifier can convert vs. the number of simultaneous DANTE sources that one amplifier can receive. This is due to the Dante flows available related to the number used within the amplifier.

    The table below shows the type of DANTE chip being deployed in each Powersoft amplifier and the number of DANTE inputs/outputs and DANTE flows available.

    Table 2 – List of Dante-enabled Powersoft amplifiers.

    Notes:

    One Unicast Dante flow (configuration by default) can contain up to 4 audio channels while One Multicast Dante flow can contain up to 8 audio channels.

    Dante “transmit” flows are used when sending audio out from a Dante device and a “receive” flow is used to accept audio in from another Dante device.

  • 4 zones on Mezzo 4-channel models

    With the release of ArmoniaPlus 2.2, 4-channel models of Mezzo now support up to 4 zones. This specific request from integrators has now been addressed and the Mezzo Series of amplifiers can drive as many zones as their total number of available outputs.

    The System design workflow within ArmoniaPlus stays unchanged apart from the 2-zone limitation on 4 channels Mezzo. This has been removed with the release of new firmware which is available for all Mezzo Series amplifiers.

    It is important to note that this feature is only available for Mezzo Series amplifiers and that this will never be implemented for Quattrocanali DSP+D Series amplifiers due to processing capabilities. ArmoniaPlus 2.2 now features greater zoning control for Mezzo Series amplifiers while building onto Powersoft user requirements.

  • Dante overflow

    ArmoniaPlus 2.2 introduces the use of Dante Overflow warnings when working with Powersoft’s Dynamic Music Distribution. This may happen when users set unique sources to play each zone since the 4-channel Mezzo can now support 4 independent zones.

    This may lead to the user believing that Mezzo can play 4 different Dante sources from 4 different Dante transmitters at the same time, while in fact, this is not the case. The Mezzo Series can only support 2 flows, In the example, Dante sources from up to 2 independent Dante transmitters.

    To prevent the misuse of Dante flows and the Dynamic Music Distribution system not working properly, users are now warned of the Dante Overflow condition when the following circumstances are both met while designing a system.

    1. When a Mezzo, 4-channel amplifier is set to drive more than 2 zones.
    2. When the same zones are linked to sources from 3 or more unique Dante transmitters.

    ArmoniaPlus 2.2 has your back every time you design with the addition of Dante flow warnings. Using ArmoniaPlus 2.2, the user can be assured that their system design will always run efficiently and properly.

  • Fanout warnings

    Dante Fan Out Warning is now also available. This new feature addresses Powersoft’s Dynamic Music Distribution and that at times designers and installers may experience no audio playback after system deployment.

    When designing Dynamic Music Distribution systems based on a Dante backbone it is possible that a unicast Dante source is set to feed more than 4 individual amplifiers at the same time. This will result in Dante fanout error and audio will not be received on all amplifiers.

    To address this problem ArmoniaPlus 2.2 now detects possible fanout conditions during system deployment within the user’s design. Upon deployment, a warning is displayed asking users to check the devices at risk as well as direct resources on fixing the problem.

    Potential Dante fanout conditions can be addressed even after system deployment by enabling multicast flows on the Dante sources creating the issue within Dante Controller.

  • Multicast Dante outputs

    By default, patching DANTE outputs of the amplifiers to other devices create unicast flows.
    In the event that more DANTE devices need to subscribe to the DANTE outputs, (2 DANTE transmitter flows for Mezzo AD and T Series and 32 DANTE transmitter flows for Ottocanali) users will find themselves running out of flows for a unicast subscription or find themselves running into a “fan-outerror. Upon finishing “Running” the project, the “Summary” page on ArmoníaPlus will also indicate that a multicast DANTE flow subscription needs to be created. To create a multicast flow, the user will need to use DANTE Controller.

    Figure 1 – Dante Controller “No More Flows” Error

    Figure 2 – ArmoníaPlus Summary Page Multicast Flows Warning

    Figure 3 – Dante FANOUT Example scheme

  • Creating multicast Dante output

    DANTE multicast flow subscriptions need to be created from DANTE Controller. To do this, the device needs to be online. The multicast flow needs to be created on the transmitter end of the Dante device. To do that, double click on the transmitter and click on “Create a multicast flow” option.

    For further information, you can always refer to Audinate’s official documentation.

  • Speaker Presets

  • Basic concepts and operations of the limiters

    The main purpose of this article is to provide a better understanding of how to use the different types of limiters available in Powersoft amplifiers. This document is applicable to the following product lines: X series, T series, Otto/Quattro/Due Canali DSP+D series, Mezzo series, and Loto DSP.

    Choosing the correct limiter is not an easy task and many aspects need to be considered, e.g.: it can be difficult to decide thresholds and time constants to obtain the correct balance between protection and sound quality, hence every decision should be based on a wider knowledge of the component to limit. Limiting may be considered an “art” and many different approaches and philosophies can be followed. For this reason, this guideline intends to simply provide a starting point on limiter parameters and how to handle them with Powersoft devices.

    NOTE: Powersoft is not responsible for misuse of the information contained in this document and/or any potential loudspeaker or other damages derived from incorrect limiter settings. This article serves as a general guideline and is subject to the context in which it is applied.

  • Are Presets for Canali Series compatible with the Mezzo Series?

    Mezzo’s DSP is different from Canali series DSP, although a lot of presets are compatible. Adding a speaker in ArmoníaPlus you can filter the list of speaker selecting the voice “Mezzo Compatible”

  • Can I link the speakers to the M and K Series amplifiers?

    Unfortunately, this function is only present on the X Series, Canali DSP+D Series and Mezzo Series. This because of the difference in the DSP.

  • Can I load an M-Series preset in the K-Series and vice versa?

    For the M and K series, there are some differences in the DSP that involves the compatibility of the presets. If you need to copy a preset for the M Series on the K Series, you should copy filter by filter manually. In addition, there are additional features on the K Series that are not present on the M Series. For more information, you can use ArmoniaPlus to add offline amplifiers to understand the differences.
