Power In & Pre Out (17-18)
These sockets c onnect the mixer/preamplifier stage to the power amplifier stage. The connecting link must be
plugged in for normal operation as a mixer/amplifier. If a compressor/limiter, equalizer, or other external signal
processor is used in the sound system, connect the "PRE OUT" to the input of the external processor
and the output of the processor to "POWER IN" In the signal chain, "PRE OUT" is after the tone controls
and the master volume control.
Loudspeaker Connections
The PA 4100 includes 4 discrete outputs and e ach output section provides two different types of loudspeaker
outputs in each one: High impedance lines (25/70/100V) and low impedance (4, 8Ω). You can only use one of
these outputs at any one time; any attempt to use two or more of these may result in damage to the amplifier.
