    INTRODUCTION Thank.you.for.choosing.the.14B Stereo.Power.Amplifier. Bryston.welcomes.any.suggestions.you.may.have,.or.comments.regarding.the.operation.of.your.amplifier...We.consider. you,.our.customer,.to.be.Bryston’s.most.important..resource,.and.your.opinion.is.very.much.appreciated.. DESCRIPTION 14B The.14B is.a.dual.channel.600.Watt.audio.power.amplifier..The.14B .can.accept.a.balanced.(3-pin.XLR..connec- tor).or.single.ended.input.(RCA.or.phono.connector).and.can.be.set.to.a.gain.of.29dB.(sensitivity.=.1V).or.23dB.(sensitivity. =.2V)...The.14B .includes.‘soft.start’.power.control.circuitry.to.eliminate.high.inrush.currents.when.A/C.power.is.applied.. The.power.up.or.turn-on.of.the.14B .may.be.activated.by.a.remote.control.voltage.4v.to.12v.ac.or.dc. SHIPPING BOX & PACKING MATERIAL Please.keep.the.original.shipping.box.and.all.packing.material..This.will.ensure.the.amplifier.is.protected.in.future.transport.. . In.the.unlikely.event.you.have.a.problem.and.must.return.it.for.service.use.the.proper.packing.material..Ship.the.amplifier. only.in.the.original.packing.material,.as.the.unit.is.not.insurable.by.carriers.otherwise.. INSTALLATION & VENTILATION The.most.important.installation.consideration.is.ventilation..The.14B .amplifier.is.convection.cooled..Unrestricted.air- flow.across.the.14B .heat.sinks.is.a.must..For.this.reason.do.not.install.anything.directly.above.it..Allow.3.5’.(2u).to.5”. (3u).inches.of.space.above.and.to.the.sides.of.this.amplifier..Do.not.install.directly.above.other.heat.generating.equipment.. Should.your.instillation.conditions.be.constricted,.then.additional.forced.air-cooling.may.be.necessary..Bryston.can.provide. an.optional.fan.package.if.required..Thermal.shut.down.during.operation.indicates.insufficient.air.flow,.and.a.remedy.must. be. found. for. cooling. the. amplifier.. Provide. a. minimum. 6”. space. to. the. rear. of. the. amplifier. for. ventilation. and. dressing.
  • Page 5 POWER AMPLIFIER UNLIT LED (No power) The.14B .LED.when.unlit.indicates.no.A/C.mains.power.is.present.and.the.amplifier.probably.needs.only.to powered.on..Ensure.that.the.rear.panel.circuit.breaker.is.switched.ON. CLIPPING (flashing red) Clipping.occurs.when.the.channel.output.level.no.longer.can.follow.the.level.increase.at.the.input.(Over.driven. input.condition)..When.the.14B .is.driven.into.clipping.the.LED.will.change.from.green.to.red.then.back.to. green.when.the.level.is.reduced.(.Flashing.Red.)..Momentary.clipping.can.be.tolerated,.however.it.indicates.that. maximum.un-distorted.power.has.been.surpassed.and.potential.speaker.damage.may.result.if.overload.condi- tions.persist..Any.amplifier.that.is.constantly.operated.into.clipping.indicates.a.more.powerful.amplifier.is.needed. for.that.application. THERMAL SHUTDOWN (orange) The.7B .has.thermal.shutdown.circuitry.to.prevent.damage.due.to.overheating..Should.thermal.shutdown. occur,.the.amplifier.will.mute,.and.the.LED.will.turn.orange.indicating.this.condition..When.the.amplifier.has. cooled.to.a.safe.operating.condition.the.14B .will.return.to.normal.operation..Persistent.Thermal.shutdown. indicates.steps.need.to.be.taken.to.increase.airflow.across.the.heat.sink. Also see installation section on ventilation. NORMAL POWER-UP SEQUENCE After.pushing.the.front.panel.power.switch,.the.LED.will.turn.from.unlit.to.red.(mute)..When.the.power.supply.has.stabi- lized.the.amplifier.will.come.out.of.mute.and.the.LED.will.change.to.green.(normal.operation).. N.B..In.some.markets.the.LED.indicators,.which.are..normally.red/green,.may.be.red/blue.instead..When.red/blue.LEDs. are.supplied.green.is.replaced.with.blue.and.orange.is.replaced.with.magenta.in.the.above.descriptions.
  • Page 6 Never connect either output in parallel with another amplifier. The minimum recommended loudspeaker load is 4 ohms. The.Output.binding.posts.provide.three.different.interconnect.options..Combinations.may.be.used.when.bi-wiring..See. figure.2.below..Cables.should.be.kept.as.short.as.practical.and.should.never.be.terminated.with.connectors.that.may. become.confused.for.AC.power.connectors..Cables.should.be.dressed.away.from.input.and.power.cables. BANANA PLUGS ●. .offer.a.quick.disconnect.option..Before.inserting.a.banana.plug.into.the.binding.post.be.sure. to.tighten.the.post.nut.to.avoid.rattling.and.to.provide.full.insertion.of.the.banana.plug..Gold.plated.locking.banana. plugs.are.available.from.Bryston.. S PADE LUGS ●. . .provide.high.contact.area.and.secure.fastening..Lugs.should.be.gold.plated..See. diagram.for.details..Post.diameter.is.5/16’.(.8mm.),.lug.width.5/8”.(16.mm)..Gold.plated.spade.lugs. 5/16" 5/8" are.available.from.Bryston..
