Operations - Technics SU-C700 Operating Instructions Manual

Measuring the characteristics
of the amplifier and correcting
its output
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.
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.
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.
∫ Turning on/off the output correction
function
Press [LAPC].
Each time you press the button:
LAPC indicator lights up
LAPC indicator goes off
≥ 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.
