This.allows.the.amplifier.to.be.switched.on.and.off.using.

Level control
The.Level.control.is.used.to.adjust.the.input.sensitivity.
of.the.power.amplifier.to.the.output.voltage.of.your.car.
sound.system.preamplifier.output.
The.adjustment.range.is.from.0.3.V.to.8.V..
If.a.car.sound.system.of.a.third.party.manufacturer.is.
connected,.the.input.sensitivity.must.be.adjusted.cor-
responding.to.the.manufacturer.data.
A few important explanations in this context:
By.turning.the.control.clockwise,.the.input.sensitivity.of.
the.amplifier.and,.therefore,.also.the.volume.increases..
However,.this.is.not.a.volume.control;.no.further.ampli-
fier.output.can.be.achieved.in.the.end.position,.even.if.it.
may.sound.like.that.at.the.beginning..The.system.merely.
increases.the.volume.faster.if.the.volume.control.of.the.
car.sound.system.is.turned.up.
Loudspeaker connections
(If.the.amplifier.is.to.be.jumpered,.continue.with.the.sec-
tion."Bridged.loudspeaker.connections".at.this.point).
As. with. every. audio. component,. the. correct. polari-
sation. of. amplifier. and. loudspeakers. is. of. essentially.
importance.for.a.good.bass.response..For.this.reason,.
ensure.that.the.positive.(+).connection.of.the.amplifier.
is. connected. with. the. positive. connection. (+). of. the.
loudspeaker;.the.same.applies.to.the.negative.(-).con-
.

nections.. In. addition,. the. left. amplifier. channel. must.
be. connected. with. the. left. loudspeaker. and. the. right.
amplifier.channel.with.the.right.loudspeaker.
Bridged loudspeaker connections
The. EMA. amplifier. can. also. be. bridged. for. a. mono.
configuration..This.allows.the.amplifier.to.be.used.for.
one.or.several.subwoofers.or.mid-range.drivers..In.this.
configuration,.the.amplifier.combines.the.right.and.left.
channel.to.a.single-channel.output.(mono.output).
Note:
The.amplifier.can.add.the.right.and.left.signal.informa-
tion.only.if.the.right.as.well.as.the.left.RCA.connection.
were.carried.out.
Caution:
In a bridge circuit, the amplifier load must be 4 ohm
or higher. A lower load leads to an overheating or
switch-off of the amplifier and can cause permanent
damages.
Adjusting the type and range of the frequency
crossovers
With.the.EMA.60,.the.type.of.frequency.crossover.(i.e..
"Low.Pass".or."Hi-Pass").and.the.desired.entry.frequency.
can.be.adjusted..For.example,.if.a.pair.of.subwoofers.is.to.
