A. Audio Inputs (see page 4)
Inputs for connecting the XA Amplier to the outputs of an
AVR, pre-pro, or other devices.
D. Speaker Outputs (see page 4)
5-way binding posts used to connect the XA Amp to your
speakers.
E. AC Fuse
Protects in case of a power surge.
F. AC Input
Use the supplied power cord to plug the XA amp in. (see
precautions on page 2).
IMPORTANT NOTE: To avoid damage to the XA amp or connected devices, please turn off and unplug
the XA amp before making any changes to the wiring.
Failure to do so can potentially result in severe damage to your amplier & loudspeakers
B. Remote Trigger Input (see page 5)
Power On/Off using 8-24v signal from connected device,
such as AVR, control system or processor.
C. ON/Trigger Power Switch
In ON position: the Power switch on the front panel turns
the XA Amp on and off.
In TRIGGER position: the XA can be turned on and off
remotely by a device connected to the REMOTE TRIGGER
jack. In this mode, the LED’s on the front panel will glow
yellow when the amplier is in standby mode, and bright
blue when powered on.
Connecting your speakers:
Use Class 2 wiring for speaker connections.
Wiring the speaker connector with bare wire:
1. Strip the insulation o ff each speaker wire to expose 3/8” (10 mm) of bare conductor.
2. Unscrew the output terminal binding post several twists, insert each wire into the correct terminal.
3. Tighten binding post by twisting clock-wise until it is rmly clamping the speaker wire.
4. For spades or banana plugs, simply insert in correct terminals.
5. Ensure + terminal goes to + terminal of speakers and – goes to – do this by checking the marking on the speaker
wire. Usually, RED wire is +
Warning: While the amplier does self-protect under most improper output conditions, misconguration of loudspeaker
mode and incorrect connection of loudspeakers could damage connected loudspeakers and/or amplier.
Please refer installation to a qualied installation professional, and always check state and local electrical codes when
installing.
Power Options:
There are 3 options for controlling the power ON/OFF
1. Select ON if you want to turn the amp on front the front panel power switch
2. The XA amps can also be powered on automatically by other devices equipped with a 12v trigger output: Select
TRIGGER position. When the switch is set to TRIGGER, the XA amp will turn on when a 12v signal is present and go into
standby when there is no signal present.
Note: If you set the ON/SIGNAL/TRIGGER switch to Trigger, but don’t connect the XA Amp to another device, the status
LED’s will be bright blue, but the amplier will not respond if you press the power button.
3.You can also turn your amp ON when it senses a signal though the RCA or XLR inputs. Select the SIGNAL option and
the amp will turn on when a signal is sensed and go into standby when no signal is sensed.
