4.2 Connecting 
outputs
4.2.1
Zone 1 and 2
Connect speakers to the 70 V, 25 V or 4 Ohm terminal 
on the Euro style pluggable screw terminal connector 
(24) at the rear of the unit.
Also see section 4.2.5 “Connecting speakers”.
4.2.2
Call only
Connect speakers to the 70 V terminal on the Euro style 
pluggable screw terminal connector (24) at the rear of 
the unit.
Also see section 4.2.5 “Connecting speakers”.
4.2.3
Music only
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 4.7).
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/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” (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 
4.7.
