Connect speakers to the 70 V terminal on the Euro style pluggable screw terminal connector (16) at the rear of the unit.

Also see section 4.2.4 “Connecting speakers”.

4.2.3Music only

Use the music master output connector (8) 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 4.6).

To select the dedicated music out source, set the internal jumper. Only the music inputs (5, 6, and 7) 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 internal jumper.
