4.2Connecting outputs

4.2.1Zone 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.

4.2.2Call 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).

4.2.3Music 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”.

4.2.4Line 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.
