EQ TONE CONTROL (for very high tones)
The BASS, MIDDLE, TREBLE, and PRESENCE controls are a 4-band equalizer
for controlling tone . The BASS, TREBLE and PRESENCE tone controls are
normal boost / cut shelving controls . The MIDDLE (midrange) tone control is
a normal boost / cut tone filter. The center detent on these tone controls yields
a flat tone response. "+12" boosts the tone; "-12" cuts the tone.
