How It Works
ConnecttheGefenTV4x1AVProcessorwithAmptouptofourHDMIsources,usingthe
suppliedHDMIcables.UseaTOSLINK®andanS/PDIFcabletoconnecttwodigitalaudio
sourcesusingtheopticalandcoaxialinputconnectors.Connectastereoanalogaudio
sourceusinganRCApatchcord.UseanHDMIcabletoconnectaHi-Defdisplaytothe
HDMIoutputoftheAudioProcessor.Usehighqualityspeakercabletoconnectthebinding
postterminalstospeakers,oruseaveorsevenchannelpoweramplierconnectedtothe
pre-ampaudiooutputterminalsoftheprocessor.UsingasingleRCApatchcord,connect
