response of speakers.
A "POWER" indicating LED, 7 slide controls (1 for
each of the bands), and an "EQ" bypass switch are
located on the front of the unit. The frequencies
boost/cut (1 to 12 dB), are modified with each filter's

the area being equalized. All frequency adjustments
are bypassed when the "EQ IN/OUT" switch is in the
"OUT" position.
