SUBWOOFER (V3000 ONLY)
The subwoofer can be operated in stereo or bridge mono, set the switch to subwoofer position
depending on your application, select the frequency from 20 Hz to 200 Hz via variable frequency
selector.
AMP MODE (STEREO/BRIDGE)
The Amplifier mode should be configured before operation, if you want to change it during perfor-
mance, you must decrease the gain controls to protect the speakers from any popping noise.
THRU
Thru will allow the user to daisy-chain one amplifiers signal input into another amplifier. Plug the
signal source outputs into the first amplifier’s input, patch from the amplifier’s THRU jacks to the
next amplifier’s input, and so on, daisy-chaining as many amplifiers as there is no excessive level
loss. Is not affected by crossover setting.
GROUND LIFT SWITCH
Applying or lifting the ground switch will change level for background noise and hum, if the noise
level remains the same in either position, better to keep the ground lift switch in the ground position.
This will eliminate 60Hz cycle Hum that is sometimes induced when mounting several units in the
same rack.

LIMITER
The limiter has a fixed threshold and will prevent continuous clipping. Below clipping, and during
short clips on peaks, the limiter does not act on the audio signal. The limiter for either channel can
be disabled independently using the slide switch on the front panel.
LOW CUT FILTER
The low-cut filter removes ultra-low frequency information from the audio signal
that could damage or cause distortion in a loud speaker system. The dip switch
on the rear panel allows you to enable or disable the filter independently for
either Channel, as well as set it for either a 50Hz or 30 Hz cut-off. Always use
the 50 Hz filter setting if you are using the amplifier to drive a distributed line system (also known as
a constant-voltage line, 70 volt line, etc.)

OPERATION
CONFIGURING THE AMPLIFIER
A 4-position dip switch on the rear panel allows you to configure certain amplifier characteristics.
A diagram on the rear panel shows the individual switch functions and settings..
LOW-CUT FILTER: Setting position 1 to “ON” enables the low-cut
filter on channel 1 and “OFF” disables it. Position 4 does the same
for channel 2.
LOW-CUT FILTER FREQUENCY SELECTOR: When
setting position 1 or 4 to “ON” then position 2 or 3 up to cut-off of 30 Hz and down is for 50 Hz.
BUILT IN PROTECTION
LIMITER: During signal overload, the limiter will reduce the input audio signal enough to minimize
the amount of clipping. During normal operation, the limiter does not affect the audio signal. It will
allow brief clipping of peaks and will only activate when continuous, hard clipping occurs. When the
signal amplitude decreases enough that clipping ends, the limiter will deactivate and cease its gain
reduction. When the input signal overloads, the “CLIP LED’s” indicate a signal overload. At this
time, the “LIMITER” switch on the front panel should be in the “ON” position or the master volume
should be lowered to reduce distortion.
INPUT/OUTPUT PROTECTION: The input circuits are isolated by 10k resistors. An ultrasonic net-
work decouples RF (radio frequency) from the output and helps keep the amplifier stable with reac-
tive loads.
THERMAL PROTECTION: Variable-speed fans provides cooling airflow. During low level output
the fan runs at normal speeds. During high output and as heat raises, (exceeding 90°C), the fan will
run at high speed to aid the cooling process. The amplifier will mute until it cools down.
SHORT CIRCUIT PROTECTION: The Output Short Circuit Protection protects the output devices
from short circuits and stressful loads. During short circuit protection, the “CLIP LED” and “PRO-
TECT LED” will light simultaneously indicating amp fault. All channel output will be interrupted (i.e.
no sound output), during the “SHORT CIRCUIT PROTECTION.” SHORT CIRCUIT PROTECTION
can usually be traced back to the signal output line (i.e. Speaker Line). Check the line from the out-
put terminal to the speaker. If this line is good, check the internal speaker connections and compo-
nents. A short circuit will usually be traced to a bad cable or a bad speaker and is rarely traced to
the amplifier itself.

LOW CUT FREQUENCY
GAIN CONTROLS
The gain controls are located on the front panel and are calibrated in DB of attenuation from full
gain. It is best to adjust the amplifier so no “hissing” is heard from speakers with no music being
played.
LED INDICATORS
Each channel has 6 LEDS. 2 green LED and 2 yellow LED for level indication, 1 red LED for power
clips, 1 red LED for short / overload, and the green LED at center for power indicator.
