Ideal for remote production, the RMA400 contains four discreet microphone amplifiers with analogue, AES and HD-SDI embedded outputs.


The unit may be controlled locally using the front panel controls and display or all functions may be controlled over ethernet. Gain range of the microphone amplifiers is 0-66dB in 1dB steps. The unit has built in limiters, switchable 48 volt phantom power, 10dB pads and high pass filters. All channels include their own metering and the microphone outputs may be monitored locally on headphones.
The unit has a HD-SDI input and output so a video source may be passed though with the four microphone amplifiers added to audio channels 1-4. All other audio will pass through unchanged. Parameter adjustment is via a purposed designed application which runs on all versions of Windows from XP to Windows 10 for easy and intuitive control.

The unit may be powered using the supplied 12 volt adaptor or a camera battery.

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.

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.

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.
