Proel predator Quick Start Guide
Predator is a dual mono feedback suppressor based on the detection and elimination of input
signal Larsen frequencies. You can connect the Predator to the desired insert point of your mixer,
according to your needs or to the kind of result you deserve.
The unit has 12 high-precision Notch filters for each channel (channel A & channel B) that function
in real time, and are able to detect and cancel up to 12 feedbacks generated frequencies
automatically, or manually (using unit buttons) or by using the remote software (via USB, MIDI or
RS232).
If you want to eliminate feedbacks from just one channel of your mixer (e. g. a single microphone)
you can connect the Predator to the channel insert of the microphone channel.
In this case you’ll obtain feedback reduction before the signal goes to EQ section of that channel.
For these insert connections you will need a particular “Y” shaped cable (see hook-up details at
page 74 – Appendix 4), which you can easily find in musical instruments and electronic shops.
suggested cable PROEL SG210LU3.
Please connect a TRS (stereo) ¼” (6.3mm.) plug in your mixer insert, then connect the mono ¼”
(6.3mm.) plug corresponding to TRS tip to predator input A, and the ¼” (6.3mm.) plug
corresponding to TRS ring to predator output A (see figure 1, page 72).
Adjust all the knobs at their minimum and turn on the unit. Then adjust the knobs as suggested in
following figure:
If you’re already feeding the unit with an input signal, you should see LCD display indicating the
incoming signal, as in the following example.
