4.2 Connecting
outputs
4.2.1
Zone 1 and 2
Connect a power amplifier to the Zone 1 and 2 Euro
style pluggable screw terminal connectors (24 and 25) at
the rear of the unit.
4.2.2
Call active contact
The call active contact is closed when a call is made via
the Tel. emergency/70V input, via the call station input,
or via the Microphone/line 1 and 2 inputs (if PTT/VOX
is selected).
4.2.3
Music only
Use the music master output connector (22) to provide a
dedicated music out source for another device. For
example, the music master output can be connected to a
telephone coupler, so that callers can listen to music
when they are put on hold (see figure 4.7).
To select the dedicated music out source, set the master
switch for “line out or music only” (21) to “music only”.
Only the music inputs (17, 18, and 19) will be audible.
All other inputs, including the Tel. emergency/70V
input will not be sent to this output.
To hear all mixed inputs (microphone/line, emergency,
and music) set the master switch for “line out or music
only” (21) to “line out”.
4.2.4
Line out/ loop through
Use the Pre-out, amp in insert (20) for external sound
processing equipment (e.g. an equalizer or Plena
feedback suppressor) to be connected between the
preamplifier and the power amplifier stages.
See figure 4.7.
