Aux Connection
The PA 120 USB/R provides an auxiliary input (19) & (20) which may be used for connecting other signal sources
such as a Radio Tuner, CD or Cassette player (LINE level). Select the type of the input (CD or AUX) from the
front panel switch (6), and connect the audio source in the adequeate rear connectors (19) or (20).
Turn the front potentiometer (5) clockwise to increase the volume or anticlockwise to reduce the volume.
The Aux / CD input sockets are standard RCA phono, two sockets are supplied and these are linked together
internally in parallel, this allows a stereo signal source to be used without the need to obtain a special lead,
however you may wish to check with the manufacturer of the signal source to ensure that no damage will result
if the left and right output channels are connected together in parallel.
RCA Phono plug connections
Tape Output Connection (18)
These standard RCA phono sockets provide a mixed output suitable for connection to a recorder such as
cassette, MP3 or computer.
Power In & Pre Out (17)
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 Connection
This device provides two different types of loudspeaker outputs :
High impedance (100V line) and low impedance (8 ohm). 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.
Loudspeaker Outputs
The PA 120 USB/R provides two different outputs for different purposes:
NORMAL MUSIC/SPEECH (15): This output, with 100V line and 8 ohm low impedance connections, gives an
output at all times, reproducing any input signal into the amplifier (Inputs 1-4, AUX, USB/SD interface). Chime
and priority conditions affect this output.
PRIOR. ONLY (16): This output with 100V line connection, ONLY reproduces a signal during priority
conditions, therefore, the output from this connection will only be present when one or more microphones is/are
in priority conditions. The chime function also affects this output.
