Instructions For Operation - SABINE FBX SOLO SL-610 Operating Manual

INSTRUCTIONS FOR OPERATION

Note: See pages 8 and 9 for front and back panel illustrations and descriptions.
The FBX automatic feedback controller improves any sound reinforcement system. By
following these simple instructions, you will be assured of the most benefit from your FBX
and sound system. The instructions presume that you are familiar with the fundamentals of
sound reinforcement. If any of the terms are not clear, or if the system does not perform as
expected, contact your local Sabine dealer for further information. Read on for a basic
explanation of FBX features you should understand before using your FBX.
POWERING UP
The only way to power up the FBX-SOLO is by connecting the power supply to
the unit; there is no power switch on the FBX-SOLO. When connecting the
power supply to the FBX-SOLO, push the connector into the input gently, with
the lip facing up as shown. Do not force the connector into or out of the FBX.
FIXED vs. DYNAMIC FILTERS
The FBX has two types of filters: FIXED and DYNAMIC. FIXED FILTERS are set during the
initial setup and retain their frequency center-points until the unit is reset by the user. The
system's gain before feedback is provided by the FIXED FILTERS; i.e., increasing the
number of FIXED FILTERS increases the system's gain before feedback. The FBX's DY-
NAMIC FILTERS control intermittent feedback that occurs during the program. They are
continually reset automatically to different frequencies as new feedback occurs during the
program. For many applications, the optimal setting is the one which gives maximum
gain - i.e., four FIXED and two DYNAMIC filters (default setting). However, in some
applications, such as use of wireless microphones, mobility is more important than
maximum gain. In this case you may wish to set three fixed and three dynamic filters.
The filters can be reconfigured easily from the factory default setting (four fixed and two
dynamic). For example, the following procedure will set three filters fixed and three dynamic:
1. Place the unit in BYPASS mode.
2. Power down the SOLO.
3. While depressing the RESET button, power up the unit.
4. Release the RESET button. The FILTER INDICATOR LEDs will now light in sequence.
5. When the third LED is lit, press the RESET button.
6. Notice that the first three LEDs flash three times to verify that they are now the fixed
filters.
Note: The fixed filters flash three times whenever the FBX is powered up.
WHERE TO PLACE THE SOLO IN YOUR SOUND SYSTEM
SL-610: Patch the SL-610 into the insert point of the desired channel. If your mixer has a
single connector insert point, connect the mixer to the IN/OUT connector on the SL-610 using
one TRS (Tip=input/Ring=output/Sleeve=ground; 1/4" phone connector) cord. Otherwise, use
the IN/OUT connector as the SL-610's input and the OUTPUT as the output. You can also
use a Y-cord from a single connector insert point. (See page 10 of this manual for informa-
tion on use with a guitar amplifier.) Use the following wiring diagrams (presented in order
of most common to least common setup) as guides for setup:
