Cautions
1. All operating instructions should be read before using this
equipment.
2. To reduce the risk of electrical shock, do not open the unit.
There are NO USER REPLACEABLE PARTS INSIDE. Please refer
servicing to a qualified service technician.
3. Do not expose this unit to direct sunlight or to a heat source
such as a radiator or stove.
4. This unit should be cleaned only with a damp cloth. Avoid
solvents or other cleaning detergents.
5. When moving this equipment, it should be placed in its original
carton and packaging. This will reduce the risk of damage during
transit.
6. DO NOT EXPOSE THIS UNIT TO RAIN OR MOISTURE.
7. DO NOT USE ANY SPRAY CLEANER OR LUBRICANT ON ANY
CONTROLS OR SWITCHES.
Connection
1. Be sure that POWER (1) is in the OFF position. All connections
must be made with all equipment OFF.
2. Before plugging in the power cord, make sure the VOLTAGE
SELECTOR SWITCH (14) is set to the correct voltage.
3. For best sound use only high quality audio cables for your hook
up. Make sure all cables are pushed in securely.
4. Use the LINE IN (11) jacks to attach your input signal to the
XG-3001. Make sure that you correctly attach the left and right
cables. You can use either RCA or 1/4" connectors. If you are
using the bridged mono mode, plug your input signal into either
the 1/4" or RCA left jack and set the STEREO/MONO SWITCH
(12) to mono.
5. The XG-3001 provides two pairs of SPEAKER OUTPUT
TERMINALS (13) to enable you to run two sets of speakers
when the unit is in the stereo mode (the STEREO/MONO
SWITCH (12) is set to stereo). You can either use banana plugs
or bare speaker wire for your connections. If the unit is being
used in the bridged mono mode, plug the speaker into the center
jacks (marked mono). You can plug one speaker into set A and
one speaker into set B. Remember, the STEREO/MONO
SWITCH (12) needs to be in the mono position.
6. A GND TERMINAL (9) is provided for grounding the XG-3001 to
your other equipment.
7. Make sure that the FAN (10) is not obstructed.
Operation
1. POWER ON: Once you have made all source connections to
your XG-3001, press the POWER (1) button, the power will turn
on and the POWER LED (2) will illuminate GREEN.
2. PROTECTION LED: The PROTECTION LED (3) illuminates
RED when the amplifier overheats or when a shorted load or DC
is detected on the amplifier output. The amplifier will reset itself
when the problem is corrected.
Note: When you first turn on the power, the
PROTECTION LED will illuminate for a few seconds.
This is normal.
3. SPEAKER SELECTION: The XG-3001 is capable of handling two
sets of speakers. To select, push the proper SPEAKER
BUTTONS (4). You can select either A, B or both A & B.
4. VOLUME CONTROL: You can easily control the output level to
your speakers (the volume) by using the rotary VOLUME
CONTROLS (5, 6). VOLUME CONTROL (5) adjusts the left
channel and VOLUME CONTROL (6) adjusts the right channel.
The XG-3001 is equipped with SIGNAL INDICTOR LEDs (7) and
CLIP LEDs (8). These LEDs will visually show the presence
and strength of a signal. The stronger the signal the more LEDs
that light. The maximum signal that should go through the
XG-3001 should cause the CLIP LEDs (8) to blink at peak music
levels. In the bridged mono mode, only the left VOLUME
CONTROL (5) will adjust the output level.
WARNING: If the
cut the levels down or the unit will go into protection.
