same time, raise the system gain and set the FBX
filters one at a time.
In some situations, raising the number of dynamic
filters (versus fixed FBX filters) may allow a second
layer of defense against new feedback from new
locations. However, in many mobile microphone set
ups, fixed FBX filters will protect against feedback
across the range of microphone mobility.
OPERATING INSTRUCTIONS
SL820 SYSTEM INITIALIZING PROCEDURE
Choose the input level. Switch to LO for instrument
or microphone in (use with low level inputs such as
piezo mics); this provides a 30 dB boost in the FBX’s
input gain structure. Switch to HI for insert or line in
(use with high level output instruments and signal
processors).
Choose the output level. Switch to Unity when you
want level in to equal level out. In the Unity setting the
SL820 has a system gain of 1 (input = output level).
Switch to Line (for line level out) if your signal needs
pre-amplification. In the Line setting the gain is ad-
justed between 0 and +35 dB via the clip level adjust.
SM820 SYSTEM INITIALIZING PROCEDURE
Select Phantom Power ON/OFF. Your SM820 is
delivered from the factory with the phantom power
function disabled. If you wish to use phantom power,
you may enable the function by switching to “Phan-
tom Power - ON” on the back panel. The majority of
low impedance balanced non-phantom-powered
mics are wired to ignore phantom power. Check your
microphone owner’s manual for verification to avoid
damage. The SM820 will not pass phantom power
from the mixer to your mic channel and is for
pre-fader channel input only.
SL820 & SM820 SETUP INSTRUCTIONS
Follow the steps on page 14 & 15 to obtain the
maximum gain before feedback without changing
the tonal quality of your program. Set up only one
SOLO at a time. The following instructions are for
using the SOLO on a channel insert. For use with
monitors, substitute monitor send and master moni-
tor control for input channel level fader and mixer
master output. Be sure to turn off the mains when
initializing the SOLO in your monitor system.
