SL820 & SM820 FRONT PANELS
POWER
The On/Off power switch is a two-position push
button switch. The LEDs corresponding to all active
filters will blink on power-up.
ACTIVE/BYPASS
In Active mode, the unit controls feedback auto-
matically. The two-color "BY" LED lights green
when the unit is in Active mode and lights red when
in Bypass mode. The mic preamp remains active in
Bypass mode; only the FBX function is bypassed.
DUAL-FUNCTION RESET
To reset only the dynamic filters, press and hold the
reset button. The LEDs will flash 3 times and then
the LEDs that indicate current Dynamic filter place-
ment will shut off (fixed filter LEDs will remain on).
To reset ALL filters, hold the reset button until all
LEDs go off (approximately 7 flashes).
LOCK FIXED FILTERS
When the "Lock Fixed" button is pressed, its LED
will light to indicate that the FBX is in Lock Fixed
mode. Lock Fixed mode can be activated at any
time after system setup and will stay on until the
button is pressed again and the LED turns off. The
dynamic filters are not affected (see p.10 for de-
tails).
CLIP LEVEL ADJUST
The front panel clip level adjust knob has two
functions, and its use will depend on the setting of
the output switch on the back panel. When the
output is set to Unity, the Clip Level Adjust allows
you to set the optimal clip level for the input signal
— in order to optimize the dynamic range while
maintaining unity gain. Higher input levels will re-
quire the Clip Level Adjust to be turned counter-
clockwise to avoid distortion; lower input levels will
require the knob to be turned clockwise, to mini-
mize noise.
