AES/EBU Input
AES/EBU input count states how many AES3 digital audio connections receive a signal.
These inputs commonly use a three-pin XLR connector. Digital AES3 is distinct from analogue balanced audio, which can use a similar-looking XLR socket.
AES/EBU Input — Upscaler
On an upscaler, an AES/EBU input receives digital audio before the selected conversion or filtering process. The resulting signal leaves through a supported output connection.
Compare the input’s supported rates with the source separately from the upscaler’s maximum output rate. A higher output capability does not establish acceptance of the same rate on this input. Do not count XLR analogue or clock-only connections as AES3 audio inputs.
AES/EBU Input — DAC
On a DAC, an AES/EBU input accepts a compatible digital source for conversion to analogue audio. Its count indicates available source connections rather than the number of analogue output channels.
Compare the source’s digital output with the input’s supported formats and rates. An analogue XLR output is not interchangeable, and AES67 network audio is a different connection system. Several inputs do not automatically imply that their signals can be mixed.
