Front Panel Indicators, Controls and Connectors

  • Indicators: Bridge mode, Ready, Signal level, Clip, Thermal error, Fault, Network data, Power, AC mains
  • LCD Control Screen and Controls: These let the user adjust the amplifier's attenuation and muting, configure the amp, set up and view error monitoring (such as temperature and load supervision), set IP and HiQnet addresses from the front panel, and recall DSP presets. The presets allow the user to quickly reconfigure the amp for various applications.
  • Level Controls (Encoders): Speed-sensitive rotary encoders, 0.5dB stpes, range 0 to -100 dB. These two knobs affect the Channel-1 and Channel-2 output levels. They also select Menu items and adjust parameter values that are displayed on the LCD Control Screen.
  • Power Switch: Push-on/push-off switch built-in green AC mains present indicator.
  • USB 2.0 Connector: Accepts a USB drive to transfer presets from the drive to the amplifier DSP, and vice versa.

Back Panel Connectors, Controls, and Indicators

  • Connectors: Balanced XLR analog inputs, balanced analog XLR loop-thru outputs, AES/EBU digital input, AES/EBU digital loop-thru output, 4-Pole Speakon output connectors, binding post output connectors, power cord, EtherCon Ethernet connector for networking via HiQnet or CobraNet.
  • Reset Switch/Circuit Breaker: If the current draw of the amplifier exceeds safe limits, this breaker automatically disconnects the power supply from the AC mains. The switch resets the circuit breaker.
  • Preset Indicator: LED flashes to signal the number of the current preset if active. LED is green if the preset values have not been changed once loaded. LED is yellow if the preset values have been changed since they were loaded.
