Operations
Before operation
1. Ensure that the connections are correctly performed.
(Normal playback cannot be achieved with wrong con-
nections of R and L.)
2. When the power is turned on or off or the 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.
3. Adjust the sound level with the volume control.
4. Operate the line straight switch, balance control, tone
control, and the like according to the reproduced source.
How to operate line straight switch
The line straight switch is used to play sound with the short-
est signaling route for enhancing the purity of the source
selected with the input selector. When this switch is set to
ON, the tone control and loudness are bypassed.
How to operate balance control
The balance control allows users to adjust the balance of
sound volume between right and left channels.
When the balance adjustment is not required, the balance
control is set to the center position.
How to operate the tone control
This unit has the tone control function for the low-frequency
and high-frequency ranges.
The low-frequency range type works in the 300 Hz or lower.
The tone control is set to flat frequency characteristic at the
center position. Rotating the control clockwise causes the
low–frequency range to be enhanced, and rotating the con-
trol counterclockwise causes the low-frequency range to be
attenuated.
The high-frequency range type works in the 3 kHz or higher.
The tone control is set to flat frequency characteristic at
the center position. Rotating the control clockwise causes
the high–frequency range to be enhanced, and rotating the
control counterclockwise causes the high-frequency range
to be attenuated.
For both the low-frequency and high-frequency ranges, the
right and left channels interlockingly function.
When the line straight switch is set to ON, the tone control
does not function.
