The XLogic Alpha VHD Pre is a slab of pure analogue attitude. Whether you need to track pristine vocals, crunched drums or electric guitars on the edge of sonic destruction, the VHD Pre delivers a powerful and versatile sound shaping tool kit -- the perfect analogue companion to any digital recording system. Based on the VHD circuit from SSL's acclaimed Duality console, the VHD Pre adds 4 SSL mic preamps to any line level DAW audio interface, transforming it into a professional quality, multi-channel analog recording system.

Features:
4 ultra-clean SSL preamps with 75dB of gain

Independently switched 48V phantom power

20dB Pad switches that illuminate to indicate overload

Hi Z switches to accommodate mic, line and instrument level signals

4 independent Variable Harmonic Drive systems

Front panel 1/4 in. jack instrument/line level inputs with passive DI type impedance detection and level matching

Individual input, output and VHD controls for each section

Rear panel XLR mic/line inputs and XLR outputs

The 4 ultra-clean, high-grade mic preamps are combined with independent Variable Harmonic Drive circuits that use 100% analog signal paths to generate rich harmonic coloration -- adding SSL analogue attitude to your digital recordings.

When VHD is used in conjunction with the input gain control, a huge variety of preamp sounds can be created, from gentle warming to serious overdrive. At relatively low input gain settings the VHD Pre preamps deliver transparent signals with… read more all of the sonic fidelity you'd expect from SSL. As the input gain setting is increased, more of the signal is passed to the Variable Harmonic Drive circuit, increasing the intensity of the effect from subtle to extreme. By adjusting the VHD control the distortion characteristics can be shifted from '50s valve-style overdrive (if the VHD selection control is turned fully anti-clockwise for 2nd harmonic distortion) to '70s transistor-style grit (if the VHD selection control is turned fully clockwise for 3rd harmonic distortion)… or a blend of the 2.

As a feature of Duality, XLogic E Signature Channel and XLogic Alpha Channel, VHD is used in studios around the world and is rapidly establishing itself as the 'go-to' tool that allows modern producers to achieve a sound that evokes the sonic heritage of SSL while adding a strong contemporary edge. read less
