SS-ALPHA-VHD
The Alpha VHD-Pre offers four of SSL's widely acclaimed VHD Pre circuits in compact 1U format. First featured on SSL's flagship Duality console,the VHD Pre is a patented SSL preamp design that can deliver ultra-clean SSL grade recordings but also features a patented 'Variable Harmonic Drive' circuit which can be switched into the signal path. The Alpha VHD pre's give you ultimate versatility from a studio grade preamp. Whether it's ultra-clean traditional SSL, subtle warming or totally trashy transistor distortion. VHD delivers a uniquely versatile pallette of rich analogue character that can be applied as a mic pre, instrument DI or line level processing device.
