Buzz Audio MA 2.2BTX microphone pre-amplifier

MA-2.2BTX

As per the MA-2.2B, a True class A discrete stereo microphone amplifier, with stepped Elma gain controls, the MA-2.2BTX includes Lundahl output transformers.

Balanced Output version

The Buzz Audio MA-2.2BTX Preamp has all the same well-loved features as the standard MA-2.2B, but features a Lundahl output transformer, providing a warmer tone than the original.

The circuitry used in the MA-2.2B preamp was developed by Buzz Audio designer Tim Farrant in the 1990's and was dubbed "True Class A". The resulting BE40 series of amplifiers exhibit a very wide frequency response (into the megahertz ) and ultra-fast slew rates (140V/uS) even at 60dB of gain. These attributes, plus the inherently low distortion provide the exceptionally pure top-end sound of the MA-2.2B.

In addition, the over-engineered power supply design with localized Class A regulators for each amplifier stage supplies the grunt needed for an authoritative and accurate bottom end - it sounds tight and never overblown.
