Front Panel Controls and Indicators
- Bridge Mode Indicator: Yellow LED illuminates when the amplifier is set to Bridge-Mono mode.
- Ready Indicator: Green LED, one per channel, illuminates when the channel is initialized and ready to produce audio output. Indicator is off when the amplifier is in standby mode via the control software.
- Signal Indicators: Three green LEDs per channel indicate the amplifier’s input and output signal levels.
- Signal: input signal is above –40 dBu.
–20 dB: amplifier output is 20 dB below clipping.
–10 dB: amplifier output is 10 dB below clipping.
- Clip Indicator: Red LED, one per channel, illuminates when the channel’s output signal reaches the onset of audible clipping. The Clip Indicator also will illuminate during Thermal Level Control (TLC) limiting.
- Thermal Indicator: Red LED, one per channel, illuminates when the channel has shut down due to thermal stress or overload.
- Fault Indicator: Red LED, one per channel, flashes when the amplifier output channel has stopped operating.
- Data Indicator: Yellow LED indicates network data activity. Data indicator flashes only when the amplifier is polled for data, or is polled to see whether it is online
- Power Indicator: Blue LED indicates amplifier has been turned on and AC power is available. The LED will flash
when the AC line voltage is 15% above or below the nominal rated value.
- AC Mains Present Indicator: Green indicator built into power switch indicates AC power is present at the power
cord and the amplifier circuit breaker is in the "on" position.
- 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), and recall DSP presets. The presets allow the user to quickly reconfigure the amp for various applications.

Noise Generator, AES/EBU Input Trim, Input Source, Maximum Analog Input, Meter Display Type.
- Monitor Menu: Speaker Load, Thermal %, AC Voltage, Operating Time, Firmware, Manufacturing Info, Networking, Thermal Errors, Clip Errors, Low Limit Load Errors, High Limit Load Errors, Line Voltage Errors.
- Menu/Exit Button: “Menu” enters the main menu. "Exit" gets out of the Menu.
- Next Button: Selects the next item in the Menu.
- Prev Button: Selects the previous item in the Menu.
- Level Controls (Encoders): Speed-sensitive rotary encoders, 0.5 dB steps, 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.

Back Panel Controls, Indicators and Connectors
- Power Cord Connector: Standard 20 amp IEC inlet. Voltage range is indicated above IEC inlet.
- 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.
- Output Connectors: Two high-current, 50A Neutrik® Speakon® NL4MLP (mates with NL4FC or NL4), one per channel. Two pairs of high-current, 60A color-coded 5-way binding posts (for banana plugs, spade lugs or bare wire). Two male XLR passive analog loop through. XLR active/re-clocked AES/EBU digital loop through.
