1. FAN.
The fan should be kept free of all obstructions and be accessible to
Cool fresh air when possible. It is important that the fan be used in a
dust free environment.
2. SPEAKER OUTPUT TERMINAL.
These terminals are for connection of speaker line to deliver power
output to speakers. Impedance (voltage) of 4 ohm: 25V, 70V and 100V
are provided for convenience. In any case, use the speakers whose combined
impedance is equal to or higher than the rated output impedance of amplifier.
Model 4ohms 24V 70V 100V
PA-9312 22V 5.2ohm 42ohm 83ohm
PA-9324 31V 2.6ohm 21ohm 42ohm
*100V or 25V can be seleted optionally.
3. INPUT JACKS.
These input jacks and terminals are for the balanced input signal.
You can connect amplifiers in parallel by using XLR jack.
4. LEVEL ADJUST CONTROL.
This control is for adjusting the level of amplifier from – 12dB to
0dB with reference input sensitivity of 0dB (1V). Rotating the
control clockwise increases the level and counter clockwise
decreases the level.
