Sonifex RB-MA1 Single Microphone Amplifier - Used

The Sonifex RB-MA1 is a single channel microphone amplifier. The connections and controls are on the rear panel. The microphone input is an XLR-3 type and is electronically balanced. The gain for the input can be adjusted by a recessed pre-set potentiometer which allows for the use of both dynamic and powered microphones.

*This is a used item. The unit is in excellent working condition with some signs of use. One of the rack ears has a slight defect. Please see images.

The line output is of an XLR-3 type and is electronically balanced. It can be wired unbalanced by grounding the non-phase signal, allowing you to feed both balanced and unbalanced equipment.

There is a switch to control a high pass filter (low frequency roll-off at 125Hz) and to provide phantom power at +48V to the connected microphone.
