The Analog Audio Input card is responsible for receiving and conditioning a balanced or single ended analog audio signal and then sending it to the crosspoint card where it can be directed to an output. This card handles 16 separate audio signals, on two separate D connectors. Each Analog audio input signal is buffered and converted to a digital format, and then formatted into an AES signal that can be sent to an DAC output card or a standard SDI output as an AES signal.
