17 EnPLAYING AND RECORDINGBASICOPERATION■ Using the CD DIRECT AMP switch(R-S700 only)Routes input signals from your CD player directly to thespecially built-in amplifier for the CD player. As a result,the input signals bypass the INPUT selector and theBASS, TREBLE, BALANCE and LOUDNESS controlsand then sent to the power amplifier, thus eliminating anyalterations to the CD signals and creating the purestpossible sound. The CD DIRECT AMP indicator lights upand the front panel display turns off after a few seconds.• If both the CD DIRECT AMP and the PURE DIRECT switchesare turned on, only the CD DIRECT AMP switch will function.• Zone 2 cannot be used while the CD DIRECT AMP feature isturned on.• The INPUT selector and the BASS, TREBLE, BALANCE, andLOUDNESS controls do not function while the CD DIRECTAMP feature is turned on.• A CD player must be connected to the CD jacks in order to usethe CD DIRECT AMP feature.• This setting is retained even if you turn off this unit.■ Using the PURE DIRECT switchRoutes input signals from your audio sources so that theinput signals bypass the BASS, TREBLE, BALANCE andLOUDNESS controls, thus eliminating any alterations tothe audio signals and creating the purest possible sound.The PURE DIRECT indicator lights up and the front paneldisplay turns off after a few seconds.• Zone 2 cannot be used while the PURE DIRECT feature isturned on.• The BASS, TREBLE, BALANCE, and LOUDNESS controlsdo not function while the PURE DIRECT feature is turned on.• This setting is retained even if you turn off this unit.Adjusting the tonal qualityCD Direct Amp featureGenerates a normal phase and reverse phase signal forboth the left and right channels from the input signaland uses the four electronic volumes to send abalanced signal to the amplifying circuit. This featureprovides clearer sound as a result of:• improved signal-to-noise ratio• external noise canceling• reduced distortionNotesCD DIRECT AMP switchNotesPURE DIRECT switch
