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: Channel’s 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
• Power Switch: Push-on/push-off switch with built-in green AC mains present indicator.
• Volume Control: Precision detented attenuator with 31 steps, press-and-hold mute function.
• Volume Control LED Ring: A ring of green LEDs around each volume control show the position of the control. Entire ring flashes when channel is muted. Can be converted to be a level meter.

Back Panel Controls, Indicators and Connectors :

• Power Cord Connector: Locking, detachable 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. Ch 1 Speakon® is wired with Ch 1 and Ch 2 outputs for use with single 4-conductor cable. Two pairs of high-current, 60A color-coded 5-way binding posts (for banana plugs, spade lugs or bare wire).
• Analog Input Connectors: A 3-pin female XLR connector for each channel.
• Analog Loop Thru Connectors: Two male XLR passive analog loop through.
• Mode Switch/Indicator: Sets amplifier to Stereo, Bridge, or Input Y mode. OFF=Stereo, YEL=Bridge, GRN=Y.
• Network Connector: This Neutrik® Ethercon connector accepts an RJ-45 connector for TCP/IQ or HiQnet networking. Next to the connector is a yellow LINK ACT indicator that shows network activity, and a green 100Mb indicator that shows a 100Mb network connection.
• Data Indicator: Yellow LED on back 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.
• Preset Indicator: Yellow LED flashes to signal the number of the current preset if active.
• Input Sensitivity Switch: Three-position switch providing 1.4V, 32 dB, and26 dB settings for both channels.
