The NEW Schertler DAVID Wood amplifier has 100W RMS power output. The new 3-channel "all-rounder" combines a comprehensive feature set with the updated technology and enhanced "look" that defines all the models in this latest range. Equipped with a 1" dome tweeter and 6" woofer, and featuring an optimized 2-way bass reflex construction, NEW DAVID offers 100W of bi-amplified power. 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. 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).
