INSTALLATION Your AMC amplifieris set to work on your local marns supply voltage. Check that your local mains supply voltage agrees with the voltage setting indicated on the back panel of the amplifier.lf not, pleasecontactyour dealeror national distributorfor details on how to proceedfurther. The cores of the mains lead are colored in accordancewith the followingcode. -Neutral Blue -Live Brown Note: Exoort units for certain markets have moldedmainsplugsfittedas standard. As the colors in the mains lead may not correspondwith the coloredmarkingsidentifying the terminalsin yourplug, proceedas follows: The wire which is colored blue must be connectedto the terminalwhich is markedby the letterN, or coloredblackor blue.The wire which is colored brown must be connected to the terminal which is marked bv the letter L. or coloredred or brown.

LOUDSPEAKERS Your AMC amplifieris designedto driveloudsoeakers wrtha nominal imoedance of 4-8ohms. LOUDSPEAKER CONNECTIONS The loudspeakeroutput terminalswill accept 4mm (banana)plugs, spade connectors,pin connectors or barewires. Connectthe negativeside(usuallyblack)of your lefthandloudspeaker leadto the blackterminalof the two terminalsmarked"L" on the rearof your amplifier. Theothersideof yourlefthandspeaker (the positive side or red) should be lead connected to the red terminalmarked"L".Reoeat thisoperation for the righthandloudspeaker. YourAMCamplifieris capableof generating high peak currents. so all connectionsmust be checkedto avoidinadvertent shortcircuitsand to ensurea goodcleancontact. UNDERNO CIRCUMSTANCES SHOULDTHE BE OUTPUTS SHORTED TOGETHER, Such actionwill damageoutputcircuitryand is notcoveredby guarantee. AC LINECORD PlugtheAC linecordintoa nearbywalloutletthat provides the correctAC powerlinevoltage,or into an unswitchedconvenienceoutlet on anv AMC products. HEATSINK/VENTILATION REQUIREM ENTS The heatproduced by yourAMCamplifier dunng normal operationis dissipatedby an internal finned heatsink.lt is perfectlynormalfor your amplifierto becomesquitewarm and to radiate heatwhenin use,especially if it is run nearfull power.However,if it becomestoo hot to touch, switchoff at onceand contactyourdealer. It is very importantthat there is adequate ventilation for the wholeof the amDlifier. Do not placethe uniton a rugor othersoft surfacethat it couldsink into,obstructing the air inlets on its underside, andtakecarenot to obstructthe outlet grilleon thetop cover. FRONTPANELCONTROLS POWERSWITCH The amplifierrs turned on by depressingthe power switch. The small indicator above the switch will glow green. Before switching on, always set the volume control to minimum to avoid damageto your loudspeakers. Note:Your AMC amplifierwill play musicalmost immediatelyafter being switchedon. However,in common wrth other audiophile products, the rnternalcircuitstake some time to stabilizefully, and the best possiblesound qualitymay not be obtaineduntil the amplifierhas had some time (possiblyan hour or two) to warm up. INFRAREDRECEIVER The infrared receiver for receivingthe infra-red srgnalsfrom your remotehandset. PHONES The headphone socket will accept any headphonesfittedwith a standard1/4"(635mm) stereojack plug.When Headphonesare in use, the output will be cut and all the amp[fier functionswill operateas normal. BALANCECONTROL The Balan:e Controladjuststhe relativelevelsof the left and right channels.lt has no effect on beingmade.A detentat the 12 o'clock recordings position marks the point of equal balance. Rotation of the Balance Control to the right (clockwise)decreases the level of the left channel so that only the rightchannelis heard. Rotation to the left shifts the sonic image toward the left soeaker. Adjust the Balance Control to produce a natural spread of sound across the space between the with any monophonic sound(suchas a speakers, radioannouncer's voice)appearingas a phantom imagecenteredmidwaybetweenthem. Recordingsoften contain small errors in channel balance,typicallyno more than 2dB; but this is enough to degrade stereo imaging. Small compensating changes in the setting of the Balance Control can significantlyimprove the depth and stabilityof the stereoimage. DIRECTSWITCH When this buttonis pressedthe Bass and Treble circuits are completely bypassed, restoring precisely flat frequency response. When this button is pressedagain, the switch will be turned off, the tone controls operate normally. By adjusting the tone controls and then switching them in and out of the signal path, you can evaluatetheir effect on the sound. BASS CONTROL The Bass Controladjuststhe relatrvelevel of the low frequenciesin the sound. The electrical resoonseof the amolifieris flattestwhen the controlis set in the detentor 12 o'clockposition. Rotation of the knob to the right (clockwise) increasesthe levelof low frequencysounds,and decreasestheir level. rotationcounter-clock-wise Adjust the Bass Control to achieve the tonal balancethat soundsmostnaturalto vou. TREBLECONTROL The TrebleControladjuststhe relativelevelof the high frequenciesIn the sound. The responseof the amplifieris flattestwhen the control is set in the detent or 12 o'clock oosition. Rotationof the Treble Control to the right (clockwise)increases lhe levelof high frequencysounds,and rotation decreases their level. Adjust counter-clockwise Treble Control to achieve the tonal balance soundsmostnaturalto you. RECORDSOURCESELECTOR This switchselectsthe inputsignalfor recording. (to TAPEOUTPUTSon rearpanel) (1) TAPE RECORDING: All sources CD, Tuner,Vrdeo,LD, Tapel and Tape2can be recordedvia the tape connections. To record an input, select the required source and set your recorderto the recordmode. To recordfrom one tape recorderto another,the playbackrecordershould be plugged into the 'TAPE1 lN'socket, and the recordingmachine into the 'TAPE2 OUT" socket. The RECORD selectorswitch should be set to "TAPEl". A recordingcan now be made in the normalway. (2)TAPEPLAYBACK: Set the input select switchto the "Tape1"(or "Tape2")positronand set your recorderinto the playback mode.
