Front Panel Controls and Indicators
* Bridge Mode Indicator: Amber LED illuminates when the amplifi er is set toBridge-Mono mode.
* Ready Indicator: Red LED, one per channel. Bright red: Channel is ready topass 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 isabove –40 dBu. Bright green: Channel’s output signal has reached the onset ofaudible clipping.
* Power Indicator: Blue LED indicates amplifier has been turned on and ACpower is available. The LED will fl ash when the AC line voltage is 10% aboveor 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 ispolled to see whether it is online
* Power Switch: Push-on/push-off switch with built-in green AC mains presentindicator.
* 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 controlshow 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 rangeis indicated above IEC inlet.
* Reset Switch/Circuit Breaker: If the current draw of the amplifier exceedssafe limits, this breaker automatically disconnects the power supply from theAC mains. The switch resets the circuit breaker.
* Output Connectors: Two high-current, 50A Neutrik® Speakon® NL4MLP (mateswith NL4FC or NL4), one per channel. Ch 1 Speakon® is wired with Ch 1 and Ch 2outputs for use with single 4-conductor cable. Two pairs of high-current, 60Acolor-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 amplifi er to Stereo, Bridge, or Input Y mode.OFF=Stereo, YEL=Bridge, GRN=Y.
* Network Connector: This Neutrik® Ethercon connector accepts an RJ-45connector for TCP/IQ or HiQnet networking. Next to the connector is a yellowLINK ACT indicator that shows network activity, and a green 100Mb indicatorthat shows a 100Mb network connection.
* Data Indicator: Yellow LED on back panel indicates network data activity.Data indicator flashes only when the amplifi er is polled for data, or ispolled to see whether it is online.
* Preset Indicator: Yellow LED flashes to signal the number of the currentpreset if active.
* Input Sensitivity Switch: Three-position switch providing 1.4V, 32 dB, and26 dB settings for both channels.
* Firmware can be updated at www.crownaudio.com > Support >Downloads.
