3. AR NN Inputs Short cables runs improve the sound quality remarkably Input cables should be short and direct since high frequencies will mostly be absorbed if the cables are unnecessarily long Besides that a longer cable may lead to humming and noise problems If the cable runs are unavoidable you should use balanced cables Outputs The high damping factor of your amplifier supplies a clear sound reproduction Unnecessarily long and thin cables used for low impedance 4 16Q speakers will influence the damping factor and thus the low frequencies in a negative way In order to safeguard good sound quality the damping factor should lie around 50 The longer a cable has to be the thicker it should be For longer cable runs please ensure the 100V outputs are used for 100V speakers Connect your speaker systems via the speaker terminals COM VE Examples 1 COM 4 160 2 COM 70V 3 COM 100V Connections To The Mains Before connecting the amplifier to the local mains voltage outlet should be checked to ensure the available supply is 240V AC 50Hz This product is CLASS1 and requires a protective mains earth to be connected at all times DO NOT remove or disconnect the earth Power On Off Procedure After connecting your amplifier to the mains turn all controls counter clockwise to the min posi tion Turn on audio sources MP3 players CD players Microphones etc before powering the amplifier ON The last product to be sw
