This manual contains important information on operating your amplifier correctly and safety. Please read it carefu lly before
operating your amplifier. If you haveany questions, contact your dealer.
UNPACKING
Carefully open the shippingcarton and check for any noticeable
damage. Every Series amplifier is completed
tested and inspected before leaving the factory and should
arrive in perfect condition. Ifyou find any damage, notify the
shipping company immediately. Be sure to save the carton

RACK MOUNTING
The Series amplifiers are designed for standard 19" rack
PPX
mounting as well as "stack" mounting without a cabinet. Use 4
screws and washers for mounting to the front rack rails. It is also a
good idea to support the amps also in the rear, especially for
mobile use where the amps will be subjected tostrong vibrations.

.
Alsopay close attention to the cooling requirements. Never block
the air vents in the back side and front of the amplifier .
Do not install the amplifier in a location that is exposed to direct
rays of the sun, or near hot appliances or radiators. Excessive
heat can adversely affect the cabinet and the internal components.
Installation of the amplifier in a damp or dust environment may
result in malfunction or accident.
If installed ina rack please be sure to open completely the back door.
Periodically remove the internal dust by using compressed air
through the external ventilation holes.

1. POWER SWITCH
Toturn the unit ON or OFF,press the upper or lower portion of
this button. Before turning on the amplifier, check all connections
and turn down the level controls.A momentary muting is normal
when turning the amplifier on or off.
(Caution: Always turn on your power amplifier last, after all your
other connected equipment, and always turn off your power
amplifier before your other connected equipment.)
2. POWER LED INDICATORS
These LEDs illuminate when the power is turned "ON".
3. CLIP LED INDICATORS
These LEDs illuminate if any section of the power amplifier s
output are within 3dB ofclipping. Occasional blinking of the LEDs
are acceptable, but if they remain on more than intermittently you
should turn down either the power amplifier s level controls or
reduce the output level of the preceding component to avoid
audible distortion.

4. SIGNAL LED INDICATORS
These LEDs illuminate to confirm the presence of an input signal
greater than 100 mV at that channel of the amplifier
5. PROTECT LED INDICATORS
These LEDs illuminate if the power amplifier s output connection
’
is shorted , the load impedance istoo low. Or if there is an internal
malfunction When either of these LEDs is lit up, turn OFF the power
and check the output's connection to verify that it is correct, then
turn ON the power again.
6. LEVEL CONTROLS
These control the level of signal coming into each channel. The
'
actual voltage attenuation of the amplifier is shown in dB. Turn these
controls counterclockwise if the Limit LEDs illuminate steadily
(indicating atoo strong input signal).
