DESCRIPTION
The DDA Series of 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.
The DSA Series operates much the same as the DDA Series; however, the DSA
Series does not include the full featured display front panel and does not provide
re-clocking of the digital input signal. The non-reclocking feature is essential
when distributing Dolby E encoded AES signals and other clocked signals that
should not be re-clocked.
DDAxxx-XLR and DSAxxx-XLR models use XLR connectors and operate from
and drive a 110-ohm balanced shielded twisted pair distribution system per
AES3-1992.
DDAxxx-BNC and DSAxxx-BNC models use BNC connectors and operate from
and drive single-ended 75-ohm coaxial cable per AES-3id-1995 and are
designed to integrate easily into video facilities.
S/PDIF (consumer) formatted digital audio data differs primarily in the use of
consumer type "RCA" audio connectors in an unbalanced 75 ohm system and
can be handled by a DDAxxx-BNC with use of an RCA to BNC input cable.
S/PDIF digital audio can be connected directly to a DSA106-RCA unit.
