VHP•2 Headphone Amplifier
Th new VHP•2 is an improved
version of the highly acclaimed VHP•1. Improvements include
a new ALPS® Blue Velvet potentiometer, gold-plated circuit
board with silver solder construction, and a handful of
upgraded internal components. As before, it is a versatile
studio quality headphone amplifier for use with most any
headphones. Unlike most amplifiers, it uses a unique
current-feedback circuit rather than opamps, and is
optimized for a wide range of load impedances (30-700
ohms).
This high bandwidth, extremely
low noise design yields greater than 120 dB of dynamic
range and exceeds the capabilities of the human ear,
ensuring that nothing audible is lost due to the amplifier.
Two gain settings, selectable by a convenient front panel
switch, allow for quick and easy optimization for high or
low efficiency headphones. Current-on-demand at the output,
enables the amplifier to respond quickly and linearly when
necessary without risk of output distortion.
When large amounts of output power are suddenly needed, the
amplifier can respond extremely quickly without raising the
noise floor of the system and degrading the signal-to-noise
performance, and the high slew rate prevents odd order
distortion. Other features include Short Circuit and
Thermal protection, looped-through output jacks and
external 14vAC power supply.
