1. AC POWER INLET
This is the receptacle for an IEC power cord, which provides AC power to the amplifier.
2. CIRCUIT BREAKER
This circuit breaker will trip if there is a fault with the main voltage or if maximum out-
put is exceed (very highly distorted). Push it in(once only) to restart the amplifier after a
short rest period.
3. SPEAKON OUTPUT CONNECTORS
These two connectors accept 2-pole or 4-pole Speakon connectors. The channel 1
connector is wired for both channels so it can be used for bridge mode wiring or ste-
reo wiring of two speakers to a single speakon.
4. 5-WAY BINDING POST
Use these to connect each channel of the amplifier to 4-ohm or 8-ohm loudspeakers.
Be sure to connect the loudspeakers correctly, with the red(+) terminal normally to the
positive input of the speaker and black(ground) terminal normally connected to nega-
tive input of the speaker.
5. FAN
Provide front to back forced airflow for cooling. Make sure that both of front and rear
panels are kept free of all obstructions and that cool, fresh air is acceptable at all
times.
6. BALANED XLR INPUTS
Connect incoming signals to these balanced XLR connectors, wired as follows : Pin 2
hot, Pin 3 cold, Pin 1 ground. We recommended the use of balanced three-conductor
cabling wherever possible.
7. 1/4" INPUTS
Balanced 2- 1/4" input connectors are provided (one per channel). Unbalanced two
conductor 1/4" plugs can also be inserted into these inputs but you will get better
signal quality and less outside noise and hum if you balanced line.
