2 – Connections
Analog audio connections
The DV-RA1000 can accept and output both bal-
anced +4 dBu and unbalanced –10 dBV signals.
Use the XLR jacks, wired as 1=ground, 2=hot,
3=cold for balanced connections, and the RCA (pin)
jacks for unbalanced connections.
On playback or monitoring, audio is always output
from both sets of connectors in parallel.
Digital audio connections
The DV-RA1000 can accept digital audio data from
one of three sources, each corresponding to a differ-
ent audio format, and can output digital data from the
equivalent type of connector, and in the same format
as it receives data.
AES/EBU Note that while AES/EBUs connections
usually use one XLR connector for a stereo pair, the
DV-RA1000 is provided with two connectors for
input and output.
NOTE
Strictly speaking, the format used by these connectors is
called IEC-60958-4, or AES-3-1992.
When working in double-frequency mode (sampling
frequencies of 88.2 or 96 kHz), there is an option of
either using one XLR connector at double speed
(double-speed), or two connectors, each at normal
speed (double-wire). If only one XLR connector is
being used, connections should be made only to XLR
connector 1 (input and output).
In quad-frequency (176.4 or 192 kHz) modes, both
connectors are used at double speed (double-speed
and double-wire).
S/PDIF These RCA pin jacks are labeled as
COAXIAL on the rear panel. The format is S/PDIF
(IEC60958).
These jacks can accept and transmit data at single-
speed (44.1 and 48 kHz) or at double-speed (88.2 or
96 kHz).
SDIF-3/DSD-raw These BNC connectors accept
and output digital audio data in SDIF-3 (DSD-Raw)
format. Each connector carries one channel of the
stereo pair.
CAUTION
When using DSD connections, all digital audio units in
the system, including the DV-RA1000, must be synchro-
nized to a common clock signal. On the DV-RA1000, if
this signal is external, a 44.1 kHz signal should be sup-
plied at the
WORD SYNC IN terminal. Alternatively,
the DV-RA1000 can be set to act as the system clock
master, at 44.1 kHz, with the DSD audio source acting as
the clock slave. See “Selecting the reference clock” on
page 22.
