Rear Panel; Input.select.switch - Bryston 14Bsst Owner's Manual

UNLIT LED (No power)
The.14B 2 .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
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.

cooled.to.a.safe.operating.condition.the.14B

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.

INPUT SELECT SWITCH
The.INPUT.SELECT.switch.allows.the.user.to.choose.between.a.balanced.input.(XLR.jack).or.single.ended.(RCA.
jack).input.

INPUT SENSITIVITY SELECTION.
This.switch.changes.the.gain.of.the.amplifier.
..●. The.29dB.setting.has.a.gain.of.28.28.and.a.sensitivity.of.1.V
..●. The.23dB.setting.has.a.gain.of.14.14.and.a.sensitivity.of.2.V
The.optimum.gain.setting.will.depend.upon.the.source.pre-amp.operating.level,.and.or.personal.preference..Use.the.
2v.setting.with.any.systems.where.the.volume.control.rotation.is.limited.to.the.bottom.half.of.the.control.or.less.
