Infused with technology from SSL's flagship large-format analog console, the Solid State Logic VHD+ Pre is a single-channel 500 Series microphone preamplifier that offers a premium gain stage and customizable harmonics for musicians and engineers at any level. Given its sonic versatility and modular form factor, the VHD+ Pre is a stellar addition to home studio setups, mobile recording rigs, and racks in commercial facilities. Between the +75 dB of gain available on the mic preamp and ±20 dB of gain via the trim knob, the VHD+ Pre delivers bountiful boost for low-output ribbon and dynamic mics or even the quietest of sources. Of course, switchable 48V phantom power is provided for condenser mics. Use the VHD control to add your choice of 2nd or 3rd order harmonics (or a blend of both) for characterful coloration. You can also keep the low-end power under control by activating the high-pass filter, which features a continuously variable frequency control from 15 to 500 Hz. Technology from the Duality Console The VHD+ Pre module for the popular 500 Series 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 ultraclean SSL SuperAnalogue-grade recordings but also features a switchable VHD mode. SSL's patented Variable Harmonic Drive (VHD) system uses a 100% analog signal path to generate rich harmonic distortion. VHD Coloration Increase the 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. At high-gain settings, it delivers fierce trashy transistoresque grunge.
