Schertler David Wood

DAVID becomes the second member of Schertler's "next generation"
acoustic amplifier series. This newly-designed 3-channel amp, combines a
wealth of new features and updated technology with a new "look".
DAVID's
inputs will accommodate a microphone, an instrument and a stereo device
such as a computer, MP3 player or CD. The instrument input and the Jack
input on the microphone channel both feature a Bootstrap technology
that enables the input to automatically adapt to any impedance.

Some of the new DAVID amplifier's new features include: three channels, a
range of controls including gain, switchable resonance (notch) filter,
adjustable DI Out in the master section, mute switch and overload LED
for each channel. A new digital reverb replaces the spring one found in
the original David models.
DAVID is also equipped with a high voltage CLASS-A preamp that has no integrated circuits and No Negative Feedback (NFB).
