Maximum AC mains voltage 264VAC.

AC Line Connector:
Five cordsets supplied with amplifi er (USA, UK, European, Australia, India).


Front Panel Indicators, Controls and Connectors

Bridge Mode Indicator:
Amber LED illuminates when the amplifi er is set to Bridge-Mono mode.

Ready Indicator:
Green LED, one per channel.
On (bright): Ready.
On (dim): Onset of compression.
Off: Thermal protection.

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 amplifi er 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 fl ashes only when the amplifi er 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 fl ashes when channel is muted.
Can be converted to be a level meter.


Back Panel Connectors, Controls, and Indicators

Power Cord Connector:
Detachable 20 amp IEC inlet.
Cord locks with supplied cord retention clip.
Voltage range is indicated above IEC inlet.

Reset Switch/Circuit Breaker:
If the current draw of the amplifi er 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 amplifi er 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 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 fl ashes only when the amplifi er is polled for data, or is polled to see whether it is online.

Preset Indicator: Green/yellow LED fl ashes to signal the number of the current preset.
LED is green if current preset is active, or is yellow if current preset is modifi ed.

Input Sensitivity Switch: Three-position switch providing 1.4V, 32 dB, and 26 dB settings for both channels.
