1.Loudspeaker output connector zone 6 : zone 6 is a 70 volt speaker line output compatible with 100 volt
speaker lines. Com = speaker ground, 70 V = speaker plus connection. If this zone is selected for
paging, it will become a normal 100 volt line. Use this output for your ‘silent’ zones.
2. Loudspeaker output connector zone 5 : zone 5 is a 70 volt speaker line output compatible with 100 volt
speaker lines. Com = speaker ground, 70 V = speaker plus connection. If this zone is selected for
paging, it will become a normal 100 volt line. Use this output for your ‘silent’ zones.
3. Loudspeaker output connector zone 4 : zone 4 is a 100 volt speaker line output compatible with
100 volt speaker lines. Com = speaker ground, 100 V = speaker plus connection.
4. Loudspeaker output connector zone 3 : zone 3 is a 100 volt speaker line output compatible with
100 volt speaker lines. Com = speaker ground, 100 V = speaker plus connection.
5. Loudspeaker output connector zone 2 : zone 2 is a 100 volt speaker line output compatible with
100 volt speaker lines. Com = speaker ground, 100 V = speaker plus connection.
6. Zone 1 balanced line level output : this is the line level output for zone 1. Connect your optional external
zone 1 amplifier here.
7. Emergency input with priority contact : the
emergency input has highest priority. This level
can be set with knob ‘8’ only
and bypasses ALL other level controls.
The emergency signal is also present on the
preamp out connectors. You can activate the
emergency input by closing a contact between the
GND and prior connections, or alternatively, activate
the input by setting the automatic vox
circuitry. Set the internal jumper marked
S3
to the
vox position and set the threshold level with
VR13
.
The jumper and level adjustment are located inside
the unit on the rear PCB. In order to reach them you
will need to open the unit.
