FBX SETUP INSTRUCTIONS

Place the speakers and micro-
phones in the positions where they
will be used during the program.
Avoid placing microphones di-
rectly in front of speakers. If you
are using a graphic EQ, adjust it
only for the desired tonal quali-
ties. DO NOT NOTCH FOR
FEEDBACK.

Set the mixer master output, all
channel level faders, and the
monitors to minimum.

Turn on the SOLO

. Turn on the

mixer, any signal processing
equipment, and finally the power
amp. NOTE: 

compressors in the

SOLO signal path should be off
during this procedure.

Press and hold the SOLO’s Reset
button (see page 8 for more de-
tails on the reset function) until
the LEDs stop flashing to clear
out all filters set previously.

NOTE: You are now in Turbo
Mode (see page 9 for details). Be
sure the “BY” LED is green to
indicate the SOLO is not in by-
pass mode (red).

Turn the SOLO’s clip level adjust
to the two o’clock position.

Set the mixer master output to a
nominal level.
