Operations

Before operation
1. Ensure that the connections are correctly performed.
(Normal playback cannot be achieved with wrong connec-
tions of R and L.)

input selector is changed over, set the volume control to
the minimum position in advance.
Playback procedure
1. Press the operation switch to turn on the switch after
ensuring that the volume control is set to the minimum
position.
2. Select a source to be reproduced with the input selector
or monitor switch.
3. Adjust the sound level with the volume control.
4. Operate the tone defeat switch, balance control, or tone
control according to the source to be played back.
How to operate tone defeat switch
(TONE DEFEAT)
The tone defeat switch is used to play back with the shortest
signaling route to prioritize the purity of the source selected
with the input selector. When this switch is set to on, the
bass and treble levels are not changed even if the tone con-
trol (BASS and TREBLE) is operated.
How to operate balance control
(BALANCE)
The balance control allows users to adjust the balance of
sound volume between right and left channels.
When balance adjustment is not required, the balance control
is set to the center position.

How to operate tone control
(TONE CONTROL)
This unit has the tone control function for the low-frequency
and high-frequency ranges.
The low-frequency tone control is a function to adjust the
tone range lower than the selected one with the selector
switch (FREQUENCY/Hz for low-frequency).
The tone control is set to flat frequency characteristics at
the center position. Rotating the control clockwise makes
the low-frequency range enhanced, and rotating the control
counterclockwise makes the low-frequency range attenu-
ated.
The high-frequency tone control is a function to adjust the
tone range higher than the selected one with the selector
switch (FREQUENCY/Hz for high-frequency).
The tone control is set to flat frequency characteristics at
the center position. Rotating the control clockwise makes
the high-frequency range enhanced, and rotating the control
counterclockwise makes the high-frequency range attenu-
ated.
For both the low-frequency and high-frequency ranges, the
right and left channels interlockingly function.
When the tone defeat switch is set to on, the bass and
treble levels are not changed even if the tone control is
operated.
How to record a source
1. Select a source to be recorded with the input selector.
2. Play the source to be recorded and set the recorder to the
recording state.
Operation of the tone control or balance control does not
affect the recording signals.
