VDP 2-Channel Tube Preamplifier
Hazelrigg Industries VDP
The VDP Dual-Channel Vacuum Tube Microphone Preamp from Hazelrigg Industries delivers exceptional sound quality for virtually any source in your studio, with an all-tube signal path to enhance any sound. Handcrafted and built for the discerning audio engineer, the VDP provides two decadent channels of preamplification with an integrated DI. The all-tube signal path imparts rich harmonic enhancement, and premium features like the transformer-coupled input and output stage ensure clear and transparent signal in every tracking session. Under the hood, VDP takes inspiration from the D.W. Fearn VT series, updating that core sound with cleaner headroom and lower noise to bring the lush vintage tone into modern studio workflows. Up to +63dB of gain provides ample headroom for compatibility with any microphone in your locker. Back-panel XLR connections integrate seamlessly into your studio rack, while the front-panel inputs for mic and DI signals make it easy to get a recording going when creativity strikes. Additional control is at your fingertips with the integrated high pass filter to clean up low end rumble, with a -20dB pad switch for added headroom when recording high SPL sources. +48V Phantom power switches are available with locking switches that help avoid accidental switching, and phase alignment is on tap to support complex mic arrays. If you're after rock solid sound in every tracking session, the VDP from Hazelrigg Industries delivers exceptional vintage vibe in a reliable modern unit.
