As many of our users have discovered, the MA-2.2 sounds amazingly vibrant when recording acoustic guitar and percussion. It is equally at home on vocal duties and you will also be very surprised how good a kick drum can sound using this preamp. The MA-2.2 matches well with all microphones types due to the transformer-less low reactance input. The noise specification is within 1dB of the theoretical minimum possible and the internal frequency response is out to 1,000,000 hertz - even at full gain. Extraordinary transparent performance that never sounds "clinical".
Each channel has a switch for Phase Reverse, 20dB Pad, Output Mute, 48V phantom power and a high/low Input Impedance selection. There is also a Peak LED
As standard the MA-2.2 has an unbalanced output, avoiding the extra stage required for this function to keep the signal path as simple as possible. The unit can however be supplied or retrofitted with high spec Lundahl output transformers. When the transformers are fitted, the direct unbalanced output is still available on the rear panel via a 1/4" jack socket which lights when the MA2.2 output reaches +18dBu.
