X4

Power supply

• Suitable for Single-Phase, Two-Phase or Three-Phase operation from 85 VAC up to 440 VAC, with automatic switching and balancing​
• Three-phase load balancing directly managed by the unit without the need for complex load assignments in the system design​
• Power Factor Correction PFC for low power consumption and compatibility with a wide range of voltages​
• Power limiters that eliminate the need for expensive power sequencers

Protections

Fully protected circuit design with:​

• Innovative failure protection aimed at keeping the system on its SOA by detecting the power delivered to speakers compared to the power drawn from mains
• Real-time measurement and processing of the output signal in order to obtain the power output: all data are collected and compared with data about the available stored energy and the power available from the mains. This makes the system immune from any misalignment such as overvoltage, overcurrent, short circuit, etc.​
• Protection against potentially harmful signals: DC, VHF, and clipping

General

• Flexible routing/mixing provided by the internal 4×4 input/ output matrix, allows the user to mix and route analog and digital I/O. ​
• 4 input channels with physical analog and digital AES3 connectors and optional 16-in/8-out redundant Dante™ connection provides maximum flexibility.​
• Improved reliability thanks to the customizable input backup strategy that automatically switches input source in case of a signal failure. ​
• Complete user interface integrated into ArmoníaPlus. ​
• WiFi remote monitoring through mobile device.
• Non-boolean channel routing
• Signal grouping for speaker routing

Monitoring

• Hardware monitor available for fast local diagnostics​
• Real-time load impedance measurement/display for each channel​
• Real-time output power measurements/display for each channel​
• Mains voltage and current measurements/display

Digital Signal Processing

• TI C6000 DSP platform architecture​
• AD/DA converter: dual 24bit @48 kHz Tandem® architecture, 127 dB dynamic range, per channel​
• Input/output independent equalizers per channel providing Raised-cosine, custom FIR, parametric IIR: peaking, hi/lo-shelving, all-pass, band-pass, band-stop, hi/lo-pass​
• Crossovers: linear phase (FIR), hybrid (FIR-IIR), Butterworth, Linkwitz-Riley, Bessel: 6 dB/oct to 48 dB/oct (IIR)​
• Input delay up to 2s and output delay up to 100ms for time alignment per channel​
• Active DampingControl™ for cable compensation​
• Power limiter (TruePower™, RMS voltage, RMS current) + Peak Limiter

Remote management

• Control and monitoring through ArmoníaPlus​
• Dedicated Web App
