The digital input will only accept digital audio signals, and will automatically
recognize either professional or consumer formats. It will not respond to non-audio
signals such as word clock, super clock, or video.

provide phase accurate multi-track recording capability. Or, one digital-audio source can be looped
through one or more AD2402-96 converters to provide a large digital-to-digital fan out for
dubbing. If the loop feature is not being used, a 75-Ohm termination should be connected to the
“Loop” connector (a 75-Ohm termination is supplied with the AD2402-96).

at 1 Vpp, and two outputs are 110 Ohm balanced at 4 Vpp. All outputs can operate in either
professional or consumer status formats. All outputs support 16, 20, or 24-bits, but the two “Aux”
outputs can be set to operate at 24-bits while the “Main” outputs operate at either 16 20, or 24-
bits. All outputs support stereo operation at sample rates up to 100 kHz on a single digital cable.
In addition, a “Main” and “Aux” output pair can be used to record “dual-cable” 88.2 or 96 kHz.
276M professional formats. The 75-ohm interfaces are well suited for long cable runs, and can
easily achieve transmission distances of 1000 feet without cable EQ, and 3000 feet with cable EQ.
AES3-id and SMPTE 276M use identical data formats and are fully inter-operable.
