4 The DIO48 Card
Introduction
The EVS DIO48 is a multi function product. Its basic function is
the conversion of asynchronous AES/EBU digital audio into
synchronous AES/EBU utilizing the on-board sample rate
converter. The DIO48 has a tracking audio delay, with a delay
offset possibility of up to 5200ms, and it can perform the Synapse
ADD-ON function.
In ADD-ON mode the card acts as a digital audio input board that
feeds a master card positioned one slot left of the ADD-ON card.
For example the DIO48 acts as a digital audio embedder when
used with the EVS ASV10 or SFS11.
The manipulated audio data that enters the Synapse bus to a master
card is identical to the data present on the local AES/EBU outputs.
The AES/EBU in and outputs are available on 75 Ohm BNC or
110 Ohm screw terminals. This choice is made with the choice of
back panel. The BPL02 has 75 Ohm AES/EBU in and outputs. The
BPL03 has 75 Ohm AES/EBU inputs and 110 Ohm AES/EBU
outputs and the BPL04 has 110 Ohm AES/EBU in and outputs.
Or 110 Ohm on a D-sub type connector BPL05D
The user has control over channel selection/swapping, gain and
phase control of all 8 audio channels.
