To optimise the audio output, you can measure the amplifier
characteristics and correct its output when it is connected to
the speakers.
≥
Disconnect the headphones. If you connect them during amplifier
characteristic measurement or amplifier output correction, it will be
cancelled.
1
Raise the power switch lever of this unit to
the [
Í
/I] position.
2
Press and hold [LAPC] until the
LAPC
indicator on this unit starts to blink.
≥
This unit will start measuring the characteristics of the
amplifier. Check that a test tone is output from both the
left and right speakers.
– If you press [LAPC] while the measurement is in progress, it
will be cancelled. The LAPC indicator on this unit will go off.
≥
When the measurement is complete, amplifier output
correction will be automatically turned on. The LAPC
indicator on this unit will light up.

function
Press [LAPC].
Each time you press the button:
≥
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
characteristics again. When you use other speakers, redo the
measurement.

≥
Reduce the volume to minimum.

Measuring the characteristics
of the amplifier and correcting
its output
Test tone emitted during measurement
To ensure the measurement accuracy, the speakers
output a test tone at regular intervals. (For approximately
4 minutes)
It is not possible to change the volume of the audio being
output while the measurement is in progress.
