The Solid State Logic VHDMICPRE for the 500-series modular rack platform brings the legendary versatility of SSL’s large-format Duality console preamp technology to any studio setup. Designed to deliver ultra-clean SSL SuperAnalogue recordings, the module ensures pristine sound quality with exceptional clarity, making it ideal for tracking vocals, instruments, or any source requiring high fidelity. Its flexible design allows engineers to harness studio-grade performance in a compact 500-series format. Equipped with SSL’s patented Variable Harmonic Drive (VHD) system, the VHD+ Pre can add harmonic richness and character to your recordings. By adjusting the input gain, users can introduce 2nd or 3rd order harmonic distortion, or blend both for a unique tonal palette. At lower gain settings, it produces subtle warmth reminiscent of valve circuits, while higher gain settings deliver intense transistor-style distortion for creative and aggressive sounds. The VHD+ Pre also provides complete control over recording and tonal shaping with features like a switchable LF filter, +48V phantom power, phase invert, PAD switch, and Hi-Z input. Whether you want ultra-clean SSL clarity, gentle harmonic warmth, or bold, trashy overdrive, the VHD+ Pre offers unmatched flexibility, making it an essential tool for both traditional studio recording and experimental sound design.
