Description
Buzzaudio MA-2.2 Class A True Discrete Dual Channel Mic Preamp -transparent amplification with the utmost warmth and clarity
The circuitry used in the MA-2.2 preamp was developed by Tim Farrant in the 1990’s and was dubbed “True Class A”. The resulting BE40 series of amplifiers exhibit very wide frequency response (into the mega-hertz ) 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-2.2. In additon, the over engineered power supply design with localized Class A regulators for each amplifier stage supplies the grunt needed for an authoritive and accurate bottom end.
The MA-2.2 sounds amazingly vibrant when recording acoustic guitar and percussion. It is equally at home on vocal and piano duties – you will also be very surprised how good a kick drum can sound using this preamp. One could say, there is not much this preamp cannot record well! The transformer-less low reactance input stage with a Wima capacitor stack matches well with all microphones types and the noise specification is within 0.5dB of the theoretical minimum possible, so ribbon and dynamic mics’ are no problem for this preamp.
Features:
POLARITY REV – this switch changes the polarity (phase) of the input.
0dB/-20dB – this switch introduces a 20dB pad right at the mic input for high level signals.
PK – this red led will light up when the QSP output level reaches 22dBu.
GAIN – 41 position detented pot that sets gain between 16 to 65dB.
MUTE – mutes the MA-2.2 output while you change mic positions. 48V – locking toggle switch turns the phantom power on and off.
HI Z/LO Z – selects the input impedance as seen by the microphone which can change the overall tone.
There is also a handy power ON/OFF switch and associated power led.
Available with optional Lundahl output Transformers.
