ATI Dual 1x4 Digital Audio Distribution Amplifier - XLR I/O
Description
DDA208 Dual 1x4 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.
The DDA208 isolated dual inputs feed AES audio each to four separate outputs. An internal switch selects either re-clocking or non-re-clocking 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 ot allow distribution of AES sync signals, Dolby E encoded AES signals, or other signals that should not be re-clocked.
DDA208 units work with AES signals that contain sample rates from 27 through 192kHz and16-bit through 24-bit density, thus permitting very high resolution signals to be distributed.
The DDA208 uses XLR input/output connectors, and operates from and drives a 110-ohm balanced shielded twisted pair distribution system per AES3-1992. Switchable line termination is provided via an internal switch. Standard practice dictates that the last AES input be terminated.
Key Features:
- Accepts sample rates from 27 to 192kHz
- Switchable re-clocking regenerates stable data before distribution
- Transformer balanced and isolated inputs
- Switchable input termination
- Individual, transformer balanced and isolated 110-ohm XLR outputs
- Eight outputs; inputs can be bridged via internal switch to provide 1x8 output capability
- Quiet, internal power supply
- AC Input 100-250 VAC 50/60 Hz, 25W Maximum
- Attractive and rugged 1RU package
