XQP 545 Optical Disrupter

$399

The 545 Optical Disrupter is an optical compressor which creates an asymmetrical waveform as it compresses. It creates second-order harmonic distortion without clipping the signal.

The effect is created by compressing only the top half of the waveform. So compression occurs, but distortion is the primary function.

Consequently the expense of a gain reduction meter has been omitted. Simply apply the amount of distortion desired and consider compression the natural by-product.

Click on image below for examples of the 545's effect on a signal as seen in a ProTools screen capture and on an oscilloscope.

Below are some audio samples of the 545. Each features three cuts of the same file: 1. original, 2. moderately disrupted, 3. more significantly disrupted. Notice how the 545 affects various sources. Be warned that all these pieces were played and sung by Dane who is rather an amateur.

Audio sample one contains bass; electric guitar (pre-overdriven); synthesizer: mellotron, strings, and vox patches; male voice.

Audio sample two contains a brief example of drums.
