The For.A MFR-16ADI Input Card is a versatile input card that can be installed in the MFR-5000 or MFR-8000 Routing Switcher to add 16 AES/EBU stereo audio inputs to the system. The board also features a sample rate converter (SRC) on each input channel, allowing users to convert incoming audio signals to a common sample rate for easy routing and processing.
