Sabine FBX Solo SL-820




Like all the FBX Feedback Exterminators, the FBXSOLO does what no other audio product can do: It automatically detects and eliminates feedback while leaving the sound crystal clear. The patented algorithm distinguishes music from feedback so it even works during the program, not just at setup time.

If you use your 31-band EQ just to shape your sound and let your FBX control feedback, you should expect up to 9 dB more gain and a dramatic improvement in the sound quality.

When you pull down a graphic EQ slider to chase feedback, you also pull out a big chunk of your sound. FBX constant-Q filters are 10 times narrower than graphic EQ filters. Narrow filters mean more gain and more clarity.
