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.
≥ Set the speaker selector knob to a position that corresponds to the
connected speakers. ( right)
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
Press the unit on/off button to the [
position.
≥ The power indicator lights up in blue.
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], turn the speaker selector knob or
operate other controls 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
≥ When the SU-R1 is connected via the system control function, you
can operate using the SU-R1's remote control.
≥ The output correction setting is applied separately to each speaker
terminal option (A/B/A+B).
≥ 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.

Operations

1
Press the unit on/off button to the [
position.
≥ The power indicator lights up in blue.
2
Turn the input selector knob.

ANALOG (dB) Select an optimal setting for the
connected device. (
(s30/s20/s10/0)
Select this setting when using
DIGITAL
the system control function.
3
Turn the speaker selector knob.
Select the speaker terminals from which audio will be
output.
OFF Does not output audio.
Outputs audio from the speakers
A
connected to the A terminals.
Outputs audio from the speakers
B
connected to the B terminals.
Outputs audio from the speakers
A+B connected to the A and B
terminals.
4
Operate the device to be used for playback.
Input selector knob setting during analogue input
≥ For normal operation, set the value to [0].
≥ For playback at low volume levels, lower the gain
value of this unit by setting the input selector knob to
[-30], [-20] or [-10] of [ANALOG (dB)]. This will
minimise analogue/digital conversion errors that
occur on this unit.
