Power supply

  • Universal switch mode power supply up to 400VAC tolerant with Power Factor Correction
  • Patented output filter with ripple cancellation network
  • Low Inrush Limiting reduces AC inrush current, removing the need for expensive power sequencers
  • Detachable AC mains cable with IEC C19/22.2 (16A for EU, 20 A for USA) socket


Fully protected circuit design with:
  • Ac protection: shut down power supply when AC mains voltage is outside operating range
  • Clip limiter: prevents severely clipped waveforms from reaching loudspeakers, while still maintaining full peak power output
  • DC protection: protects against infrasonic signal at the outputs
  • VHF protections: protects the loudspeakers against non audible, strong, non musical high frequency signals
  • Short circuit protection: protects the amplifier from short circuit or other stressful events for the output circuits with automatic protection reset
  • Long term limiter: protects the loudspeaker against steady long term RMS (non audio) signals, by reducing maximum output
  • Thermal protection: output stages operating temperature up to 80 °C (176 °F)
  • Temperature controlled continous variable speed fan, front to back airflow


  • Fixed frequency switchmode output stage for high grade sound accuracy
  • Compact 1 RU for reduced rack cost and space
  • Light weight - for easier racking and shipping: 5-11 kg (11-24.3 lbs) depending on number of BatFormers
  • Standard Phoenix connectors: analog and digital input, audio outputs, aux supply, alarms and GPIO
  • Remotely switchable inputs (main and aux) per channel

Loudspeaker system configuration

  • Direct drive either low impedance loads or 70V / 100V Hi-Z distributed lines
  • Switchable 35Hz / 70Hz high pass filter per channel
  • Built-in defeatable clip limiters for each channel
  • Mixed configuratio with Lo-Z/Hi-Z systems possible
  • Bridged mode low impedance per channel pair

Alarms and GPIO

  • General Purpose Input/Output alarm interfaces
    • dangerous DC in the output power signal
    • thermal stress
  • Configurable alarm contact NC/NO per channel
  • Remote AUX input / MAIN input switch
  • Remote ON/OFF switch
  • PWS OUT connector providing up to 24VDC

Digital Signal Processing

  • Analog Devices® ADAU 1702 DSP architecture
  • AD/DA converter: dual 24bit @ 48 kHz Tandem® architecture, 100 dB dynamic range, per channel
  • Input/output independent equalizers per channel providing PEQ, shelving IIR filters
  • Delay up to 16 ms for time alignment
  • Active DampingControl™ for cable compensation
  • Peak and RMS limiters

Remote management

  • Control and monitoring through ArmoníaPlus
  • Interface available for MediaMatrix, Crestron, AMX, Q-SYS and monitoring systems
