Aux Connection; Loudspeaker Connection - HQ -HA30W Installations- Und Bedienungsanleitung

Chime
Switch on the chime on/off switch on the rear panel and short the pin4, pin5 of DIN
socket or short the sleeve and ring of phone plug Mic 1. This will activate the chime function
("Ding-Dong" attention signal preceding a call).The default volume of the chime is pre-set at the
factory and is adequate for most applications.
Telephone Connection
This input is for emergency announcements/signals and is not effected by the master volume
control. Input level can be set by level control on the rear. The TEL input has the highest priority
and will override all other inputs.

Aux Connection

This amplifier provides two auxiliary inputs that may be used for connecting other signal sources
such as a radio tuner, CD player or cassette player. The level control operates individually. Turn
the control clockwise to increase the volume or anticlockwise to reduce the volume.
The Aux input sockets are standard RCA phono, two sockets are supplied and these are linked
together internally. This allows stereo signal sources 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 put in parallel.
RCA Phono plug connections
Sleeve: Screen
Pin: Signal
Tape Output Connection
These standard RCA phono sockets provide a mixed output suitable for connection to a tape or
cassette recorder.
Power In and pre Out
Connects 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 equipment provides four different types of loudspeaker output, these are 100V, 70V and 25V
line and low impedance, you can only use one of these outputs at a time. Any attempt to use two
or more of these may result in damage to the amplifier.
