Parameter Operations
*2: “XY” means “operate X, and then operating Y.” For example, “[SELECT] A encoder” means that you should press the [SELECT]
A, and then operate the encoder.

Operation Description
Changing the attenuator
value (volume)
attenuator
(ATT)
[SELECT] (of the channel to
be changed) encoder
*2
The [SELECT] indicator of the selected channel
will lit, and the attenuator value can be edited by
the encoder.
The range of adjustment is -99 dB–0 dB in 1 dB
steps.
Changing the polarity
polarity
(POL)
[SELECT] (of the channel to
be changed) encoder
*2
The [SELECT] indicator of the selected channel
will light, and the polarity can be changed by using
the encoder.
Changing the high pass fil-
ter (HPF) cutoff frequency
Turning off the high pass
filter (HPF)
HPF
(HPF)
[SELECT] (of the channel to
be changed) encoder
*2
The [SELECT] indicator of the selected channel
will light, and the high pass filter (HPF) on/off set-
ting and cutoff frequency can be changed by using
the encoder. This will be set to 80 Hz if a high
impedance connection is specified; it will be turned
OFF if a low impedance connection is specified.
In order to protect the amplifier, the HPF of the
selected channel cannot be turned OFF if a high
impedance connection is specified.
Switching between analog/
digital input
analog/digital input
selection
(SRC)
Encoder operation
The [SELECT] indicator of the selected channel
will light, and you can use the encoder to change
the analog/digital input selection.
Do not select “analog” if your audio network has
been configured using the [YDIF] connectors or
Dante [PRIMARY]/[SECONDARY] connectors.
Selecting “analog” will interrupt audio transmission
to and from the devices that are connected via the
YDIF connectors or Dante connectors.
Switching whether the
[SIGNAL] indicators are
used for input or for output
[SIGNAL] indicator
switching
(SIG)
Enco
der opera
tion
Use the encoder to specify whether the [SIGNAL]
indicators will show the input signal level or the out-
put signal level.
Digital input sensitivity
selection
* Digital input sensitivity: the
digital input level at which
the input attenuator is 0 dB
(volume maximum) and the
amplifier is at maximum
output; refer to “Block Dia-
gram” (page 236).
digital input
sensitivity
(DIS)
Encoder operation
Use the encoder to change the digital input sensi-
tivity setting. To prevent inadvertent setting, the
value does not change right away when the
encoder is turned. Until the input sensitivity
changes, “
–––” appears in the display.
