Description
Sonifex RB-MA2 Dual Channel Microphone Amplifier Details The RB-MA2 consists of two independent low-noise
microphone pre-amplifiers for converting mic level signals to line
level, or for driving long lines from microphones to processing
equipment.
All connections and controls are on
the rear panel. The microphone inputs are XLR-3 type and are
electronically balanced. The input gain for each input can be adjusted
individually by a recessed pre-set potentiometer which allows for the
use of both dynamic and powered microphones.
The XLR-3 line outputs are electronically balanced and can be wired unbalanced
by grounding the non-phase signal,
allowing you to feed both balanced and unbalanced equipment. For
each channel there are independent switches to control a high pass
filter (low frequency roll-off at 125Hz) and to provide phantom power
at +48V to the connected microphones.
