The.PA8506-V,.with.its.entirely.digital.audio.processing.and.sophisticated.control.system,.has.been.carefully.designed.and.built.to.comply.with.

the.most.stringent.safety.standards.and.to.guarantee.high-quality.sound.and.intelligibility..The.input.routing.section.is.able.to.manage.several.

sources.of.sound.such.as.microphones,.calling.units.and.devices.for.background.music,.including.USB.storage.units..The.power.stage.has.

two.250.W.Class.D.amplifiers.serving.the.“voice”.and.“music”.channels,.and.the.speaker.output.section.consists.of.six.separate.zones,.with.

independent.control.of.the.music.volume.for.each.zone..The.“Music”.amplifier.also.has.the.function.of.a.back-up.unit,.automatically.replacing.the.

“Voice”.amplifier.in.the.event.of.a.failure..Furthermore,.each.zone.output.has.two.circuits.for.loudspeaker.lines.(A.and.B).to.ensure.full.coverage.

of.the.area.even.in.the.event.of.a.failure.of.the.circuit.of.one.of.the.two.lines..

The.multi-purpose.front-panel.controls.and.the.LCD.display.make.programming.and.set-up.easy..In.addition.to.the.normal.broadcasting.of.

announcements.and.music,.the.PA8506-V.is.capable.of.sending.out.alarm.calls.in.emergency.situations.via.the.on-board.hand-held.microphone.

or.via.remote.dedicated.emergency.units..Furthermore,.in.accordance.with.EN54-16,.it.is.monitored.constantly.in.order.to.signal.any.upsets.

promptly..It.is.possible.to.connect.two.PA8506-V.units.to.one.another.so.as.to.combine.two.6-zone.systems.and.configure.a.single.system.with.a.

total.of.up.to.12.zones..The.line.connecting.them.can.be.as.long.as.one.km.and.the.remote.emergency.stations.will.ensure.overall.management.

of.the.whole.system.
