Technics SU-C700, Operating Instructions Manual

13

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.

∫

Turning on/off the output correction 
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.

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.
