1 1 STEREO GRAPHIC EQ
Your PBM8.350 UM is equipped with a stereo graphic EQ for MAIN MIX, and a
mono EQ for MONITOR MIX. Each EQ provides 9-band fader controls. Via these
faders, you can boost/attenuate the selected frequency up to 15dB at a
preset bandwidth. When all faders are at the center position, the equalizer
output is flat response. They are used to modify the frequency "contour" of a
sound. Since there is no bypass switch, the EQ function will be activated as
soon as you turn on your PBM8.350 UM.
