12 TONE Switch
When you set it to the DEFEAT position, sound will be reproduced
without signals going through the tone control circuit. Use the ON
position when you want to control tonal! response with the tone s’
tors and tone controls.
13 TREBLE Tone Selectors
14 TREBLE Tone Control
Use the TREBLE tone selectors and control to adjust the treble or
high-frequency response of instruments such as cymbals. The TREBLE
tone selectors select the frequency above that to which the TREBLE
tone contro! has been adjusted; use one of the two positions (6 kHz or
3 kHz).
15 BASS Tone Selectors
16 BASS Tone Control
Use the BASS tone selectors and control to adjust the bass or low-
frequency response of such an instrument as a bass. The BASS tone
selector select the frequency below that to which the BASS tone
control has been adjusted; use one of the two positions (300 Hz or
150 Hz).
17 SUBSONIC Filter Switch
Superlow-frequency noise, caused by warped or off-centered records,
forces the moving structure of a woofer to work excessively; such
abnormal excursion generates distortion. This filter cuts such superlow-
frequency noise below 16 Hz and improves bass response.
