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.
TURNOVER FREQUENCY switch < For AX-1070 only >
These switches can be used to adjust the turnover point of the
tone controls: either 200 Hz or 400 Hz for BASS and either 2.5
kHz or 5 kHz for TREBLE. This gives you flexible control over
bass and treble response characteristics.
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.
