The VHD Demo Preamp features a stereo pair of balanced line inputs, stereo RCA phono connectors, and a very high quality VHD microphone preamplifier. The microphone channel features phantom power, four band equalization and a variable high pass filter. The output is routed to one of two switchable A or B outputs. Feeding the same outputs is the switchable Line / RCA phono inputs with additional two band music EQ and input pads. Both A and B outputs have line drivers built into them to maintain audio signal integrity over long cable lengths.

The Demo Preamp was built as a part of KV2 Audio’s VHD product philosophy focused on delivering very high definition audio and acts as a small stand alone mixer where just one microphone, a CD player and a main left and right balanced input are needed. As a demo tool it gives a distributor, dealer or end user the ability to demonstrate KV2 Audio systems to their highest potential, and then offer A/B comparisons against other products using the A/B switched outputs. The A/B switching can also be triggered remotely using an external switch patched into the rear of the unit.
