There are two types of input jack on this unit, BALANCED
jack input and UNBALANCED jack input. The input types
are independent from each other, and gain settings can be
independently set.
The procedure for setting the gain settings is the same for
BALANCED input and UNBALANCED input.
The standard gain can be set across a +6dB to –6dB range.
The factory default setting is ±0dB (23dB) from the standard
gain.
1. Press the BALANCED (UNBALANCED) button for 3
seconds. The display changes from the power display to the
gain setting mode, and the current gain value is displayed.
In the gain setting mode, the amplifier switches to mute,
and no sounds are output.
2. The setting value changes every time the BALANCED
(UNBALANCED) button is pressed. Press the BALANCED
(UNBALANCED) button until the desired gain value is
displayed.
3. When the desired gain value is displayed, press the
BALANCED (UNBALANCED) button for 3 seconds to
complete the setting.
The set gain value is displayed for 3 seconds, then the
display returns to the normal power display. At the same
time, muting is released, and sound is output.
