XQP 545 Optical Disrupter

XQP 545 Optical Disrupter.

The XQP 545 Optical Disrupter is a feed-forward optical compressor that creates an asymmetrical waveform resulting in very smooth distortion as found in single-sided circuits.

Primarily induced by low frequencies, the top half of the waveform is increasingly sloped as compression increases. The signal is not clipped at all. As distortion is the object, there is no gain reduction meter - a single LED glows in proportion to Disruption.

News Flash:
Xvive VTL5C1 optocouplers have been tested positive for use in the Disrupter!.

"I am loving this thing, used it to mess-up a boring synth bass line. Epic!

Everybody that loves using distortion in music should check out the 545! I use them on vocals, bass and sometimes drums.

The only problem with this box is I need more of them... !!

"A compressor but a raucous effects box at the same time..."
