Application 3: Global music/message buffered and distributed to multiple amps with local override input for each amplifier
Similar to the paging situation found at airport departure gates, global music/messages play when no local page is
present. During local page (from departure gate microphone), music/message mutes to predetermined level and
page is heard only in local area. When local page is complete, global music/message fades back to previous level.
During local zone page, global music/message mutes only in local area, then fades back. Buffered global music/mes-
sage signal is unaffected by local paging condition.
Mode of Operation: 70V Mono or Dual Mono
Amplifier Adjustments:Volume of local (departure gate) MIC is adjusted by the "A" Level Control. Global music/mes-
sage source is adjusted by the "B" Level Control. Set Lo-Cut or Channel Balance, depending on mode of operation.
Module Adjustments:Adjust Gain to make each sources’ input similar. Adjust Bass & Treble (where applicable) to your
preference.Adjust Ducking on BRG1R for desired level. Adjust Gate control on MIC1X for optimum paging oper-
ation.
Application 4: 2 mono zones, low-impedance speakers, telephone paging and background music. Zones have significantly
different volume levels
Background music plays through the system when no page is being made. One zone is low volume while the other
is high volume. During a telephone page, the background music mutes to a predetermined level and the telephone
page is heard at correct volume level for each zone.When the page is complete, the background music fades back
to its previous level.
Mode of Operation: Dual Mono
Amplifier Adjustments: Volume of the telephone page is adjusted by the "A" Level Control. Background music level is
adjusted by the "B" Level Control.Set the Lo-Cut switch to Flat or 65 Hz. Channel Balance control on rear of ampli-
fier adjusts the volume level of one speaker zone over the other zone. Rotate the Channel Balance control towards
the "B" marking (counterclockwise) to reduce the volume level of the speakers connected to the "A" output ter-
minals while leaving the volume level of "B" speaker output unchanged.
Module Adjustments: Adjust Gain to make each source’s input level similar.Adjust Bass & Treble (where applicable)
as appropriate. Adjust ducking control on MAX1R for desired level. Adjust Gate controls of TEL1S for optimum
paging control.
