FBC (Feedback compression) function can effectively suppress howling expansion volume, ensure voice
transmission quality, high fidelity, and clear sound.
The dynamic filter and the static filter function the same. Used to remove devices above or below a
certain frequency.
To increase or decrease a range of frequencies in sound by passing them through. The differences
between them are:
1. Static filters do not clear filters like dynamic filters. The frequency points that have been captured are
fixed in position.
2. The dynamic filter will be automatically eliminated, and the captured frequency is not fixed.
Even in poor environments, it can greatly suppress the howling and can effectively prevent burn out
audio equipment and speakers.
1. FBC input Select
There are 12 inputs to choose from. When the corresponding input is lit, the filter of this channel will work.
The default is a dynamic filter. The 1-24 light will turn green.
2. FBC Output Assign
There are 12 outputs to choose from. When the corresponding output is lit, the filter of this channel will
work. The default is a dynamic filter. The 1-24 light will turn green.
FBC Setting:
3. FBC Mode:
Speech & Music is suitable for meetings and music occasions, howling and clearing are
automatically captured.
4. Filter Release:
Fast / Mid / Low. Click here to determine the speed of dynamic filter elimination. Fast
/ Mid / Slow.
FBC Setup:
5. Static Filters Setup:
The default is a dynamic filter (the indicator is green). Click Static Filter Setup to
switch to static filter (the indicator light is red).
6. Clear Dynamic Filters:
Initialize all dynamic filters.
The automatic elimination time of dynamic filter has time limit of 2s~3s.
At this time, you can press this button to remove immediately.
7. Clear All Filters:
Initialize all dynamic and static filters.
8. Bypass:
Bypass this area function.
9. 1 - 24 indicators:
Once the system detects the frequency for processing, if it is set as a static filter, the
indicator boxes 1 to 24 turn red, and the filtering effect is reflected on the graph. For dynamic filters,
attenuation will also appear in the graph and indicator box lit in green.
Attention:
Because the
M-800RM
are used for broadcast, The input RD9/10 of FBC page would cancel
automatically when
M-800RM
insert to RD9/10. The FBC function has no effect at this point.
After the M-800RM is connected, the corresponding output is automatically turned off . The purpose is to
avoid: no broadcast but also has output.
