In this example, the main stereo programme feed from a radio station needs to be distributed
across multiple platforms. The output from the desk or automation system no longer just
heads off to the transmitter. The audio must be distributed across all of the relevant services
that require a connection of the original programme audio.
The Signature DDA 1:6 provides 6 stereo AES outputs of the main AES programme audio.
One output connects to the transmitter as the main FM broadcast feed. As multiple guest
headphones are required in the studio, another output connects to a separate AES
headphone distribution amplifier. This station also broadcasts online, so another output
connects to a PC to become the internet broadcast stream. Local monitoring is required, so
one feed goes to the local AES monitoring system. The transmitter B chain is on ISDN, so one
AES output goes to an ISDN codec. And the final output connects to another PC that
manages all of the stations logging requirements.
It’s very easy to see why multiple outputs of the main AES programme audio are required in a
typical radio station environment.
