Proel Sound Processors User Manual
With this unit you have the chance to adjust each channel 12 notch filter for automatic or manual
operation.
Immediately after turning on the unit, the initial configuration is for 11 automatic filters and 1
manual filter. So you can immediately do an automatic scan to detect feedback frequencies.
Move the encoder “” until “search feedback A” item, then press “ENTER” button to “launch”
channel A feedback detecting circuit.
LCD display should be as follows.
ARs
B sens Rs
- - - - - - - - - - - M
- - - - - - - - - - - M
A e B represent channels.
means sensibility with value numbers from 1 to 15, 1 is a value for low sensibility while the
maximum sensibility is 16. You can choose the desired sensibility.
“Rs” allows you to simultaneously reset all the filters.
Each segment represents a filter, and it will have the “ – “ sign for automatic filter and “M” for
manual filter.
To select and/or modify each filter (sensibility) move the cursor selector over its segment
and modify its value by “VARIATION” knob.
To reset a filter, move the cursor on “Rs” then to move the “ENTER” button.
Feedback automatic scan is only possible for filters set to operate in this way. Instead manual
filter(s) will operate on feedback reduction applying the parameters you manually set.
A segment overstretching from top to bottom shows predator automatic filter feedback detection
and reduction.
A longer perpendicular segment will indicate higher filter attenuation for that feedback frequency.
To exit from “search feedback A&B / A / B” mode, you just need to press the “ESC” button.
Warning: the above Quick Start Guide example concerns Preset01 only. Other presets may have a
different number of automatic and manual filters, as well as other parameters.
