One of a kind distortion and compression await your API 500 Lunchbox!
A VPR 500 series product, the XQP 545 uses a pair of VACTROL® optoisolators to create compression which results in an asymmetrical waveform in the low freqencies.
There is no clipping of the waveform, yet a thick, smooth, even-order harmonic distortion results from this process.
Effects ranging from subtle tape saturation to deliberate distortion can be easily achieved on material with low frequency content.
