This module has been specifically designed to operate in a 500 format rack such as the API lunchbox® or equivalent.
In common with many such modules, the nominal input/output level is +4dBu. The VHD Pre is an immensely versatile recording and processing device. It can deliver ultra clean SSL SuperAnalogueTM grade recordings but also features a switchable VHD mode. SSL’s patented Variable Harmonic Drive (VHD) system uses a 100% analogue signal path to generate rich harmonic distortion. As you increase VHD input gain, the Variable Harmonic Drive process introduces either 2nd or 3rd harmonic distortion or a blend of the two to your source material. At lower gain settings it adds gentle valve-style warmth or a touch of transistor edge. As the gain is increased the more extreme the distortion becomes until at high gain settings it delivers fierce trashy transistoresque grunge.
