Using the PURE DIRECT switch
RX-485 only
You can enjoy the purest possible sound from your audio
sources by setting this switch ON. By doing so, the audio
signal bypasses the BASS, TREBLE, BALANCE and
LOUDNESS controls, eliminating any alterations to the audio
signal.
When you listen with headphones
Connect the headphones to the PHONES jack. When listening
with headphones privately, set both the SPEAKERS A and B
switches to the OFF position.
Adjusting the BASS and TREBLE
controls
Adjusting the BALANCE control
Selecting the SPEAKER system
Adjust the balance of the output volume to the left and right
speakers to compensate for sound imbalance caused from
speaker location or listening room conditions.
Because one or two speaker systems can be connected to this
unit, the SPEAKERS switches allow you to select speaker
system A or B, or both at once.
BASS
: Turn this clockwise to increase (or counter-
clockwise to decrease) the low frequency
response.
TREBLE : Turn this clockwise to increase (or counter-
clockwise to decrease) the high frequency
response.
Adjusting the continuously variable
LOUDNESS control
This control provides compensation for the human ears’ loss of
sensitivity to high and low-frequency ranges at low volume.
This control is adjustable to retain full tonal range at any
volume level.
