4.2 Connecting outputs
4.2.1 Zone 1 and 2
Connect a power amplifier to the Zone 1 and 2 XLR
connectors (25 and 26 ) at the rear of the unit.
4.2.2 Call active contact
The call active contact is closed when a call is active.
4.2.3 Master output
Use the music master output connector (23) 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 4.9).
To select the dedicated music out source, set the master
switch for “line out or music only” (22) to “music only”.
Only the music inputs (18, 19, and 20) will be audible.
All other inputs, including the Tel. emergency/100V
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” (22) to “line out”.
4.2.4 Line out/ loop through
Use the Pre-out, amp in insert (21) 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 4.9.
