The MMA-4 is a minimalist microphone preamplifier that has been designed to provide integrity and transparency. Consistent with this, each channel has only controls for gain (60dB in 3dB steps), phase invert, cut (mute) and 48V phantom power.
The Phantom power circuit provides a higher-than usual level of current output - often a problem with inferior designs which can result in compromised microphone performance. An LED bargraph clearly shows signal level with conventional green, yellow and red colouring for highest levels.
Output headroom extends to +28dBu.
