DDA-212 Series 2 Digital Audio Distribution Amplifiers are designed to regenerate, isolate and distribute digital audio data formatted in accordance with specifications AES3-1992 and IEC 958. This is commonly called AES/EBU formatting or AES3.

DDA-212 Series 2 units have two inputs and 12 outputs, with the assignment of inputs and
outputs configurable from a front panel switch. The unit may be operated as a Dual 1X6 or
as a 2-Input 1X12, depending on the Input Select switch setting. The selected input feeds
AES audio to either six or all 12 separate outputs.

A front panel switch selects either re-clocking or non-reclocking of the input signal. In most
cases, re-clocking is preferred, as this feature improves the integrity of weak or distorted
input signals. Re-clocking may be switched off to allow distribution of AES sync signals,
Dolby E encoded AES signals, or other signals that should not be re-clocked.

DDA-212 Series 2 units work with AES signals that contain sample rates from 27 through
192kHz and 16-bit through 24-bit density, thus permitting very high resolution signals to be
distributed.

The front panel displays full status of the input signal, including Sample rate, Word Length,
Digital Errors and Pro or Consumer Mode.

DDA-212 Series 2 units contain a unique automatic equalization function that can adjust for
extremely long input lines. Equalization works independently for each input. A Front Panel
Lock feature protects all your settings.

The Model DDA-212XLR uses XLR connectors and operates from and drives a 110-ohm
balanced shielded twisted pair distribution system per AES3-1992.

Input Loop-through connections for each of the two inputs are provided to permit multiple
units to be stacked, or to insert the DDA-212 into your digital workflow. Switchable line
termination is provided. Standard practice dictates that the last AES input be terminated;
therefore, if you are not using the loop-through feature, Input Termination should be
switched ON.
