4.2Connecting outputs

4.2.1Zone 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”.

4.2.2Call 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”.

4.2.3Music 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”.

4.2.4Line 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.
