The Solid State Logic VHD+ Pre Module for the popular 500 format modular rack platform makes the uniquely versatile VHD based preamp technology from Duality, SSL’s industry leading large format studio console, available for studios of all sizes. The VHD+ Pre module is an immensely versatile recording and processing device. It can deliver ultra clean SSL SuperAnalogue 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.
Increase Solid State Logic VHD+ input gain and 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.
The Solid State Logic VHD+ Pre module gives the user ultimate versatility from a studio grade preamp. Whether it’s ultra-clean traditional SSL, subtle warming or totally trashy transistor distortion, VHD will change your expectations of what a preamplifier should deliver.
