Pre-owned Buzz Audio MA2.2 Class A Mic Amplifier

Very good condition. 48v flaky on one channel. See all pics.

The Buzz Audio MA-2.2 is a dual-channel microphone preamp that uses fully differential, discrete solid-state Class-A circuitry. It is known for its clean and detailed sound, making it suitable for recording vocals, acoustic guitar, piano, and drums with exceptional clarity and accuracy. The preamp features a high standard of construction and can be specified with various options such as different input impedances and output configurations.

The MA-2.2B model, an upgraded version, replaces the gain potentiometer with a calibrated 24-position Elma stepped switch for precise stereo matching between channels. It also includes a 19-segment peak output level meter and illuminated push-button switches for "click less" operation. The preamp's input stage uses a stack of Wima film capacitors instead of an input transformer, which avoids low-frequency phase problems and provides a cleaner sound. This design ensures compatibility with various microphone types, including ribbon, capacitor, and dynamic microphones.

Reviews indicate that the MA-2.2B provides a very clean, precise, and detailed sound that is devoid of any obvious character, making it a top choice for those who prefer a transparent and uncolored preamp. It is particularly praised for its ability to capture the true essence of the source material without adding coloration.
