LIMITING THE TOTAL NUMBER OF ACTIVE FILTERS
You may choose to limit the total number of active filters for each application by using the
"LOCK FIXED" button. For example, if you wish to use only three fixed and one dynamic
filter, set the FBX so there are five fixed and one dynamic filter. Then during the setup
procedure, simply press the "LOCK FIXED" button after setting the first three fixed filters.
The remaining two fixed filters will be locked in their zero position.
SELECTING FILTER WIDTH
If the SOLO is to be used for a music application, 1/10-octave filters are most effective.
However, in spoken word applications, such as lectures or teleconferencing, the wider 1/5-
octave filters are recommended. Select the filter width using the switch on the SOLO back
panel. The change takes effect only on power-up. Selecting a new width has no effect unless
you power down and then power up again.
ENGAGING THE NOISE GATE
One outstanding feature of your FBX-SOLO is a user-selectable noise gate. It acts as an
automatic switch that opens a microphone only when someone is speaking directly into the
mic. A noise gate is especially useful in systems that have a number of open microphones,
such as courtrooms, conference rooms, or parliament buildings. Gating microphones greatly
reduces the number of possible feedback points in the room and allows for more system
gain.
The level that turns the noise gate on and off is called the threshold. If the level coming into
the gate is greater than the threshold, the noise gate opens, and the mic is
turned on. If it is less than the threshold, the noise gate closes, and the mic is
turned off.
You can adjust your SOLO to four different threshold levels (see diagram at
right), or turn it off. To select the threshold, power down the SOLO. Hold in
the LOCK FIXED button, and power up the SOLO. The clip level LEDs will
light in sequence. Select the threshold level by pressing the LOCK FIXED
button again when the clip LED lights at the corresponding threshold level.
The noise gate is now enabled, indicated by a flashing level LED on power-
up. Pressing the LOCK FIXED button with no clip LEDs lighted turns off
the noise gate. If no lights flash on power-up, the noise gate is not
engaged. When the SOLO's noise gate is enabled, it will not become
engaged until after you've set all fixed filters and one dynamic filter (if the
SOLO is configured for any).
USING SABINE'S OPTIONAL SOLO ACCESSORIES
1-U rack tray (model #SL6RACK):
An optional 1-U rack tray holds up to six SOLOs. Mount the SL-610s, SM-610s, or a combi-
nation of both side by side on the tray. Use only Sabine supplied screws; use of any other
screws may damage the SOLO and void the warranty.
