Drawmer HQ D.A.C.


The monitor pre-amp is one of the most important pieces of equipment for both audio professionals and Hi-Fi enthusiasts alike. It enables critical evaluation of the audio signals and is the final stage before the speakers, so it requires zero coloration, precise balance, low noise, wide bandwidth and a variety of input sources.

hq-logoTop of the range designs use relay attenuators with high accuracy resistors to achieve the best balance between channels. The downside of this approach is the distraction of noisy ‘chattering’ relays which can be irritating but also reduces relay life. The Drawmer HQ incorporates an innovative solution to this problem, providing the feel and smoothness of a potentiometer but with the accuracy of relay attenuation. Accuracy between channels to within a 10th of a dB has never been accomplished before, but the HQ provides just that.

The ingenious control system allows you to hook up a miriad of sources, each with individual gain settings, for precise A-B comparison. A great sounding, quiet DAC and ultra low crosstalk, and speaker switcher add to the mix to create a must-have converter for serious studios.
