Power Switch
Switches the
XMP300
on or o f f. A red LED indicates connection to AC power
while in standby mode. Turns green indicating audio signal is present.
2.
Speaker Selector
Selects speaker zone A or B. For A + B zones push both buttons in.
3.
Balance
Fades speaker output between the Right and Left Channels
4.
V olume
Adjusts amplifier volume.

Interupting Line Input
This is the secondary input, use MAIN IN for your main input.
INTERRUPTING INPUT can be used if a second source is desired and
takes over when signal is present and has at least a 5mV level.
When there is no signal, or a signal with less than 5mV level, the amp
switches back to MAIN IN after a brief delay.

AUTO ON Select Switch
Power can be turned on and off manually via the switch on the front panel
or automatically by signal sensing. Set it to NORMAL for manual power on/off.
Set to AUTO for signal sensing; the amp will turn on when audio signal is
detected at the inputs. NOTE: The front panel power switch must be in the
ON position (pushed in) for the AUTO ON featu
r
e to operate.
Speaker Zone A Output
Speaker output terminals for zone A. Minimum impedance: 8 ohm bridged
or 4 ohm stereo.
Speaker Zone B Output
Speaker output terminals for zone B. Minimum impedance: 8 ohm bridged
or 4 ohm stereo.
Power Cord
This amplifier is configured for operation at 115V (North America). A fuse
located internally protection from fault conditions. Refer to qualified
service personel should this need to be replaced.

MAIN IN should be used as the “primary” or main input for the amplifier.
Connect your receiver or main source to this input. Use MAIN OUT to pass
MAIN IN signal to another amplifier.
If you will be connecting one or two pair of speakers to the amplifier, place
the switch in the “Stereo” position. NOTE: For playing 2 pairs of speakers
(A plus B), make sure each speaker has an impedance of 8 ohms or greater.
When set to “Bridged” mode, the amplifier is a single channel mono amplifier.
NOTE:
The XMP300 supplies 450W in bridged mode, Please verify that your
speakers are capable of handling such power to avoid possible damage!
For stereo output connect the speaker’s positive (red) terminal to the amplifier’s
positive (red) terminal, and the speaker’s negative (black) terminal to the
amplifier’s negative (black) terminal for each Right and Left speaker.
NOTE:
To prevent sonic degradation in your speaker installation, total speaker
wire resistance should be kept below 0.5 ohms. This table lists recommended
speaker wire gauge versus wire run length.
Place the “MODE” switch in the “BRIDGED” position and use both red
terminals to connect to the speaker. Connect the speaker’s positive (red)
terminal to the amplifier’s red (+) terminal noted next to the bridging mark, and
the speaker’s negative (black) terminal to the amplifier’s unmarked positive
NOTE:
Only one zone (A or B) can be bridged. Do not attempt to bridge both
A and B speaker terminals! This may result in a lower impedance than the
amplifier is designed for and may damage your amplifier. The minimum
impedance for the total load connected in bridged mode is 8 ohms.
STEREO MODE
BRIDGED MODE
BRIDGED MODE- MONO APPLICATION
For bridged mode, playing Right and Left together as mono output, plug
RCA cables in to Right and Left RCA at MAIN input.
Set the MODE switch to BRIDGED and follow the instructions
for bridged speaker connection in the SPEAKER TERMINALS section of
this manual.

(red) terminal.
NOTE:
Use Class 2 wiring for speaker connections.
To wire the output connector: 1. Strip the insulation off 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.
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.
