Level Control (4). The controllable range is
wider by 150Hz, 300Hz and 600Hz respectively.
The Bass Level Control, which functions in
conjunction with the Bass Frequency Selector,
is a tone contro! of the lower range of the fre- ae
quency response. It is designed so that response © = re
is flat at the mid-position. A clockwise turn intensifies the low
frequency range, while a counter-clockwise turn yields attenua-
tion. For easy adjustment, the control is equipped with an 11-
point click-stopper.
This contro! is of dual concentric construction, and usually
both channels are controlled simultaneously.
Separate contro! of either channel! is possible if oe — tess
one axis is turned while the other is held by
hand. The inner axis is for the left channel and
the outer axis is for the right channel.
These same descriptions are applicable to the
Treble Level Control (6) and the Treble Fre-
quency Selector (7). The Treble Frequency
Selector has 3 positions: 6KHz, 3KHz and 1.5KHz
