Your RCA 10-Band Stereo Graphic
Equalizer gives you greater control over
your audio system’s sound. As you play or
record an audio source, you can tailor the
sound to suit your personal listening
preferences or to compensate for poor
recording quality, components, speaker
placement, or the room’s acoustics.

Your equalizer offers the following
features:

Stereo Image Enhancer – enhances the
stereo effect.

Spectrum Display — gives you a visual
display of the sound level of each
frequency band.

Tape Dubbing — lets you copy a tape
from one tape deck to the other.

Tape Monitoring — lets you listen to the
recorded sound.

Bypass — lets you play and record
without equalization.
