A. Audio Inputs (see page 4)
Inputs for connecting the XA Amplifier to the outputs of a
surround processor, preamplifier AV receiver with pre-out
connection, DVD player with discrete 5 channel output, or
HDTV with built-in surround decoder.
D. Speaker Outputs (see page 4)
Use these 5-way binding posts to connect the XA Amp to
your speakers. Works with - speaker cable with bare wire
(solid or stranded), spade lugs, or banana plugs.
E. AC Fuse
Protects in case of a power surge.
F. AC Input
Connects XA Amplifier to an AC power source with the
supplied power cord (see precautions on page 2).
IMPORTANT NOTE: Before Attempting to connect any Jacks into any power amplifier verify that the
power amplifier is turned off And/or disconnected form AC power.
Failure to do so can potentially result in severe damage to your amplifier & 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 button on the front panel acts as
the main AC switch, turning 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 amplifier 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 firmly clamping the speaker wire.
4. For spades or banana plugs, simply insert in correct terminals.
5. 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 amplifier does self-protect under most improper output conditions, misconfiguration of loudspeaker
mode and incorrect connection of loudspeakers could damage connected loudspeakers and/or amplifier.
Please refer installation to a qualified installation professional, and always check state and local electrical codes when
installing.
Auto Power ON:
To use another device with a 12 volt trigger output jack to automatically power on the XA:
1. Select Trigger position.
2. Connect a 3.5mm mono jack from the trigger-output jack of the source device to the REMOTE TRIGGER jack on the
When the switch is set to TRIGGER, the goes into standby mode and the front panel LED ’s glow yellow. When the con-
nected device is turned on the status LED ’s glow bright blue.
If you set the MANUAL/TRIGGER switch to Trigger, but don’t connect the XA Amp to another device, the status LED’s will
be bright blue, but the amplifier will not respond if you press the power button.
