The StudioHub+ MJ-AD MatchJack is a professional stereo Analog to Digital Converter. Inputs are Analog S/PDIF and RJ45 converted to AES/EBU digital. The input signal is converted to a balanced professional level via an RJ45 wired to StudioHub+ pin-out standards. Sample rates of 32kHz, 44.1kHz, 48kHz and 96kHz are automatically selected based on the detected source sample rate. Power is supplied either via StudioHub+ "DC-Link" power (through either input or output RJ45) or via the "wall wart" power supply (included). The StudioHub+ AD MatchJack is housed in a plastic enclosure.
So, must all the audio and digital signals used with StudioHub+ be balanced?
Yes, or crosstalk will degrade. That's why they provide the "MatchJack" balancing amplifiers, AES/EBU digital audio signals are balanced right out of the box, and require no conditioning.
