Signal Inputs
AES/EBU Digital Inputs
3 pin XLR Female (4 off –
AES 1 – AES 4
)
Used for AES3 format signals.
AES 1
and
AES 2
are used together in
Dual
AES
mode. All four inputs are used together for
Quad AES
or
DSD Quad
modes.
AES/EBU Reference Loop
3 pin XLR Female / Male (
AES Ref Loop IN
&
OUT
)
Loop IN
is used for AES3 references and also for Sync Link operation in multi-
channel synchronising.
Loop OUT
is hard-wired to
Loop IN
, allowing the
reference to be daisy-chained through several units.
Sync Input
BNC
This is intended for future enhancements.
SPDIF Inputs
Various (3 off –
RCA IN
,
BNC IN
,
TOS IN
)
Used for SPDIF inputs. Pull the plastic dust cover out of the
TOS
input before
use.
DSD/SDIF Input
BNC (4 off –
CH1 IN
,
CH2 IN
,
WCLK IN, LOOP OUT
)
The upper group of four DSD/SDIF connectors form an input interface. They are
used as a set for SDIF-2 (PCM or DSD) or SDIF-3 (DSD only).
used as a set for SDIF-2 (PCM or DSD) or SDIF-3 (DSD only).
WCLK IN
may be used to sync the unit to an external reference wordclock
while taking data from another input.
WCLK IN
is internally wired to
LOOP
OUT
, allowing a reference wordclock to be daisy-chained through several units.
When the daisy-chain is not used, the
LOOP OUT
connector must be fitted with
a 75
Ω BNC terminator.
WCLK IN
will also accept a 10 MHz GPS reference.
