Digital Input and Output
The digital input and output connections on the DP569 may seem unfamiliar to the
first time user of a digital audio device. The Audio Engineering Society (AES)
created a standard electrical interface for digital audio with a balanced XLR
connector and 110
first time user of a digital audio device. The Audio Engineering Society (AES)
created a standard electrical interface for digital audio with a balanced XLR
connector and 110
Ω impedance called AES3-1995. This interface was later expanded
to include an unbalanced BNC connector, 1 V peak-to-peak signal level, and 75
Ω
impedance; the new standard is known as both AES3-ID-1995 and SMPTE-276M.
The DP569 uses this new standard.
The DP569 uses this new standard.
Note: These signals must be properly terminated with a 75
Ω impedance on the last
device in the signal chain. External 75
Ω terminations for standard installations
are supplied within the packing kit for the DP569.
