Front Panel Controls and Indicators

• Bridge Mode Indicator: Amber LED illuminates when the amplifi er is set to Bridge-Mono mode.
• Ready Indicator: Red LED, one per channel. Bright red: Channel is ready to pass audio. Red: Onset of compression (thermal event or fan failure). Off: Thermal event has occurred.
• Signal Indicators: One green LED per channel. Solid green: Input signal is above –40 dBu. Bright green: Channelʼs output signal has reached the onset of audible clipping.
• Power Indicator: Blue LED indicates amplifier has been turned on and AC power is available. The LED will fl ash when the AC line voltage is 10% above or below the nominal rated value.
• Data Indicator: Yellow LED on front panel indicates network data activity. Data indicator flashes only when the amplifier is polled for data, or is polled to see whether it is online
