This dual mono or stereo DSP controlled microphone amplifier was originally designed to be mounted on a camera but may be used anywhere a good quality mic amp is required.

CMA20 The mic amp outputs are available simultaneously as analogue or unbalanced AES . Each mic amp each has a gain range of +30dB to +60dB with a switchable 10dB pad available. Phantom power (48volts) may be selected to either or both microphones. There is a high pass filter for dealing with those windier locations.
Each microphone's level may be checked on the built in LED meter and may be monitored via the headphone jack.
All settings except gain are push button and are held in memory. The buttons auto-lock after 3 minutes.
Power requirements are 12 volts DC supplied via the 4 pin XLR.

This quad mono or dual stereo DSP controlled microphone amplifier is perfect for 'piggy backing' remote audio onto HD-SDI video. Simply plug this unit in series with the video stream. CMA20

The four mic channels are assigned to channels 1-4.
Features of the unit are similar to the CMA20, each mic amp has a gain range of +30dB to +60dB with a switchable 10dB pad available. Phantom power (48volts) may be selected to either or both microphones. There is a high pass filter for dealing with those windier locations.
Each microphone's level may be checked on the built in LED meter and may be monitored via the headphone jack.
All settings except gain are push button and are held in memory.
If not manually locked, the buttons auto-lock after 3 minutes.
Power requirements are 12 volts DC at around 750mA supplied via the 4 pin XLR.

Programming the B-MA2 is easy using the OLED display which meters output levels during normal operation.

The following features are programmable:

• Channel1/channel2 gain 30dB to 60dB
• Channel1/channel2 phantom enable
• Channel1/channel2 phantom voltage 12V/48V
• Highpass filter none/some/lots

Power requirements are a PP3 size 9V battery (alkaline recommended) or a 9-16 volt external DC supply.
