9. Unplug the amplifier during lightning storms or when unused for long periods of time.
10. Refer all servicing to qualified service personnel. Servicing is required when the amplifier
has been damaged in any way. Some examples-when the power cord or plug is damaged, liquid
has been spilled, objects have fallen into the amplifier, the amplifier has been exposed to rain
or moisture, it does not operate normally, or has been dropped.
11. Never break off the ground pin and connect only to a proper power supply type, indicated
on the unit. For more information, write for our free booklet “Shock Hazard and grounding”.
12. If this product is to be mounted on an equipment rack, rear support should be provided.
13. Exposure to extreme high noise levels may cause permanent hearing loss. Individuals vary
considerably in regards to noise-induced hearing loss, but nearly everyone will experience some
damage if exposed to intense noise for an extended period of time.
The US Government’s Occupational and Health Administration (OSHA) has specified the
following permissible noise level exposures:
SOUND LEVEL dBA, SLOW RESPONSE
DURATION PER DAY IN HOURS
8
90
92
6
4
95
3
97
2
100
102
105
110
115
1 1/2

1/2
1/4 OR LESS
According to OSHA, any exposure in excess of the above permissible limits could result in
some hearing loss. Ear plugs or protectors to the ear canals must be worn when operating this
amplification system, in order to prevent permanent hearing loss, if exposure is in excess of
the limits as set forth above. To ensure against potentially dangerous exposure to high sound
pressure levels, it is recommended that all persons exposed to equipment capable of producing
high sound pressure levels such as this amplification system be protected by hearing protectors
while this unit is in operation.

OPERATION
1. INPUT GAIN (dB)
These controls are used to adjust the input gain of each channel. They determine how loud
each channel of the power amplifier will sound for a given input signal level. The maximum
input gain is achieved by turning the control completely clockwise - this setting yields the
maximum mixer/system headroom. Turning the control back counter-clockwise will yield lower
system noise at the expense of mixer/system headroom. Turning the control fully counter-
clockwise turns this setting off. It is always a good idea to power up any new installing at this
setting to protect the system loudspeakers.
2. POWER LED (POWER)
These indicators illuminate when the AC main power is being supplied to the amp and both
channels are operational. If either channel experiences faulty conditions, exceeds safe operat-
ing temperature limits, or if the main circuit breaker trips, then both channel power LED will
be dark, indicating shutdown. If the BRIDGE mode is selected, the PWR indicator on channel B
will remain dark as a positive indication of this mode selection.
3. SIGNAL ACTIVITY LEDS (SIGNAL)
These indicators illuminate when the associated channel output signal level exceeds 1 Volt RMS.
4. OVERLOAD LEDS (CLIP)
These indicators illuminate when the associated channel has been overloaded.
5. FAULT LEDS (FAULT)
These indicators illuminate when the amplifier has just been turned on or if the amplifier has
detected a problem, such as overheating or circuit problems.
6. POWER SWITCH
This heavy-duty, rocker-type switch turns on the power to the amplifier. When the unit is turned
on, there is a three-second delay, which reduces/eliminates the turn-on transients associated
with the system equipment connected to the amplifier and protects loudspeakers.
7. LEVEL INDICATOR
Channel A and Channel B level LED indicator.
8. INPUT
Cannon and input jack connector provide balance or unbalance input mode.
9. MODE SWITCH
This switch is used to select STEREO or BRIDGE mode operation.
10. GROUND LIFT SWITCH
11. BINDING POST OUTPUTS
Shockproof binding posts are provided. For each channel, the outputs are in parallel and the
speaker connection cables can be terminated with banana plugs or stripped wires.
12. SPEAKER OUTPUT
The amplifier provides (3) four conductor speaker connectors, one for each channel and one
for bridge mode.
13. POWER SELECT
Switch to choose 110V-120V or 220V-240V power supply.
14. POWER INPUT
This is a standard IEC power connector. An AC main cord, which has the appropriate AC plug and
rating for the intended operating voltage, is included in the carton.
15. FAN GRILL
(Two) 2 speed DC fans supply cool air to the amplifier. The fans switch to high speed automatically
when the unit requires additional cooling.
