Basic Description
The VHD Preamplifier is a Very high definition, small stand-alone microphone and stereo inputs signal
mixer.
Primarily built for high quality, easy presentation and comparisons of two individual systems using the
same source, the applications for this mixer are comprehensive and extremely useful.
The VHD 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 VHD Preamplifier also features two switchable A or B outputs, to allow a simple comparison of
systems between the two outputs. Both A and B outputs have line drivers built into them to maintain
audio signal integrity over long cable lengths.
