When this switch is set to the 'l 5Hz position, the subsonic
filter with a cut-off frequency of 15Hz is actuated. The
subsonic filter serves to attenuate frequencies lower than
15Hz in a 6dB/oct slope. lt is therefore effective in
suppressing ultra-low-frequency noise which is generated
by record warp and other causes. You cannot actually
hear this noise but it is a factor in the generation of
intermodulation distortion and it may damage your
speaker system. Set this switch to the 1SHz position
during record play for the best effect.

Set this switch to ON when adjusting the bass and treble
controls. When set to the upper (OFF) position, the tone
control circuits are disengaged and frequency response is
flat. This function is convenient for checking phono car-
tridge and speaker tone quality and listening room
acoustics.

treble will be accentuated.

to hear the bass and treble than when the volume is high.
The loudness switch is thus designed to compensate for
this deficiency. By setting it to ON, the bass and treble
come through much more strongly and the sound takes on
a punch even when the volume control is turned down.

Conversely, if the sound appears to be louder on the left,
it means that the volume of the left channel is higher.
Therefore, turn the balance control to the right and
adjust.
