Front Panel Features
Gain (Level) Controls:
Two black rotary level controls,
one for each channel.
Cooling Vents:
Front-to-rear forced airflow
through foam dust filter.
Sel/Prev/Next Buttons:
Three buttons located
underneath the LCD screen
used to access menu items
and front panel lockout.
USB 2.0 Connector:
Accepts a USB drive to transfer
presets from the drive to the
amplifier DSP, and vice versa.
Power Button & Indicator:
Push-on/push-off switch glows
green when AC power is present at
the power cord and the amplifier
circuit breaker is in the “on”
position.
LCD Screen:
Backlit liquid crystal display
shows enabled presets and
speaker processing.
Indicators:
Fault Indicator: Red LED, one per channel, flashes when the amplifier output channel has stopped operating. Usually this means that the amplifier must be serviced.
Thermal Indicator: Red LED, one per channel, illuminates when the channel has shut down due to thermal stress or overload.
Clip Indicator: Red LED, one per channel, illuminates whent the channel’s output signal reaches the onset of audible clipping. The Clip indicator also will illuminate
during Thermal Level Control (TLC) limiting. The Clip Indicator can be turned of during Blackout mode.
-10 dB Indicator: amplifier output is 10 dB below clipping.
-20 dB Indicator: amplifier output is 20 dB below clipping.
Signal Indicator: selected input signal is abouve -40 dBu.
Ready Indicator: Green LED, one per channel, illuminates when the channel is initialized and ready to produce audio output. Indicator is off when the channel is set
to standby mode via System Architect or in Blackout mode.
Back Panel Features
Binding Post Output Jacks:
One pair per channel of high-current,
60A color-coded binding posts. Accepts
banana plugs,wire of spade lugs.
Fans:
Provide front to back

Connector
4-Pole Speakon
®
Output Connectors:
These two connectors accept 2-pole or 4-pole Speakon
connectors. The channel 1 connector is wired for both channels
so it can be used for bridge-mode wiring or stereo wiring of two
speakers to a single Speakon.
Network Connector:
This EtherCon
®
Ethernet
connector is for networking.
Warning: Only connect to
networks that remain inside
the building.
Reset Switch/
Circuit Breaker
Balanced Analog
XLR Inputs:
Provide front to back
forced airflow for cooling.
Balanced Analog XLR Loop-Through Outputs:
Two 3-pin male XLR output connectors are provided (one per
channel). The signal at these connectors is paralleled with the
Input signal for feeding the input signal to other amplifiers.
AES/EBU Digital Input:
This 3-pin female XLR
connector accepts a digital
signal in the AES/EBU format.
Fans:
Provide front to back forced
airflow for cooling.
