©LOUDWeSSB Control
This boosts the extreme low and high frequencies
to compensate for our ears7 reduced sensitivity to
these frequencies at low volumes. Set it to the
FLAT position while the VOLUME control is set
to your normal maximum listening level. Turning
it counter-clockwise will reduce the volume while
retaining the natural balance between low and high
frequencies.
||BASS and TREBLE Controls
The bass and treble controls have a low turnover
frequency of 350 Hz and a high turnover frequen¬
cy of 3.5 kHz respectively. In the flat positions,
the tone control circuits7 frequency response is
completely flat.

This control, centered about 3 kHz, readily
adjusts for mid-range characteristics.
iOALANCIE Control
The balance knob controls the difference in out¬
put volume between the L and R {left and right)
stereo channels. Set this control to the center "Q"
position, at which there is a click stop, unless you
need to correct for a lack of balance between the
audio level of the two channels, or to correct for
a listening position which is not equidistant from
the two speakers. The balance control reduces the
volume from the left-hand speaker when turned
clockwise, and reduces that from the right-hand
speaker when turned counter-clockwise.

© SVB UT1IMG /OTS Switch
When this switch is in the ON position, the Opti¬
mum Tuning System {OTS) will minimize the
effect of any mis-tuning, and will ensure continued
optimum reception of FM stations. In the OFF
position, accurate manual tuning is essential. Even
in the ON position, however, OTS is automatically
switched off when you touch the tuning knob,
permitting manual tuning. The FM muting
function ensures that both inter-station noise and
weak signal strength stations will be muted. In the
OFF position even the weakest stations will be
heard.
® TUNER FM/AM Switch
This determines whether AM or FM stations will
be received.
