• AC Power cord
• Warranty Card
POWER CONNECTION
The PPA-300 has an internal power supply and is designed to operate from an external AC source. Power requirements
for electrical equipment differ from area to area. Be sure to confirm that the voltage is your area is 115V, 60 Hz
RACK MOUNTING
The PPA-300 amplifier is designed for standard 19" rack 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 to shocks.
AMPLIFIER COOLING
Also pay close attention to the cooling requirements. Never block the air vent in the back side and front of the amplifier if
the amplifier is being run at high output levels. For best results in such high output power applications you should
augment the amplifier’s air flow with a rack cooling system.
