MASTER SECTION
Your PBM8 is equipped with two graphic EQs with 9 adjustable bands each; one is
for the MAIN MIX and the other for the MONITOR MIX. Via the faders, you can
boost or cut the selected frequency by +/-15 dB at the indicated frequencies.
When all faders are at the center position, the equalizer will do nothing.
11 STEREO GRAPHIC EQ
Pressing this button the feedback detection function will be activated in the
monitor signal path. Feedback will be identified at a certain frequency when
the correspondent fader LED lights up. Feedback will produce an unpleasant
speaker "howling" or "whistling". In this case, in order to eliminate feedback,
you need to turn down the corresponding fader until feedback disappears.
12 FEEDBACK TERMINATOR Button (MONITOR MIX)
This LED display will show you the monitor output level. Make sure that the
+10 LED only lights up occasionally. The optimal level is when the -10 and
0 LED light up. If only the -30 LED lights up or even doesn't come to life your
S/N ratio will be degraded.
13 MONITOR LEVEL LED DISPLAY
By pressing this button, the feedback detection function will be activated in the
Main Mix signal path. Feedback will be identified at a certain frequency when
the correspondent fader LED will light up. Feedback will produce an unpleasant
speaker "howling" or "whistling". In this case, in order to eliminate feedback, you
need to turn down the corresponding fader until feedback disappears.
