  Measuring the output signal of the 
amplifier and correcting its output 
(LAPC)
 ■  Preparation
 •  Disconnect the headphones.
 Test tone emitted during measurement
 To ensure the measurement accuracy, 
the speakers output a test tone at regular 
intervals. (For approximately 3 minutes)
 It is not possible to change the volume of the 
audio being output while the measurement is 
in progress.
 1 Press [AMP 
] to turn this unit on.
 2 Press and hold [LAPC] until “Please 
Wait” is displayed.
 “LAPC Measuring” is displayed and this unit 
will start measuring the output signal of the 
amplifier. Check that a test tone is output from 
both the left and right speakers.
 When the measurement is complete, amplifier 
output correction will be automatically turned 
on.
 •  The amplifier signal measurement is cancelled 
in the following condition.
 - Pressing [MUTE]/[LAPC]
 - Switching the input source
 •  If you connect headphones during amplifier 
signal measurement or amplifier output 
correction, it will be cancelled.
 ■  Turning on/off the output correction 
function
 Press [LAPC] to select “On”/“Off”.
 •  LAPC indicator lights and “LAPC : On” is 
displayed while the output correction function 
is in progress.
 Note
 •  Set to “Off” when using output correction 
function for the connected speakers because 
the correction function (LAPC) effects on the 
audio output from PRE OUT terminal. ( 20)
 •  Depending on the type of the connected 
speakers, the effect of the output correction 
function may be minimal.
 •  The corrected output remains in effect until you 
measure the output signal again. When you use 
other speakers, redo the measurement.
 You can make the optimum adjustment according to your own speakers.
