STEP 1 – Selecting a Digital Input
Switch on the source equipment. If appropriate, load a disk / tape and set the machine in PLAY mode
to ensure it is generating a digital audio data stream.
Choose one of the following sections:
Connecting to an IEEE 1394 DSD Source
•
Check that your source equipment (probably a
dCS
SACD Transport or a
dCS
Upsampler) is
capable of DSD operation over a 1394 link, generates a 44.1kHz word clock and is set up correctly.
•
Connect
one
1394 output on your source equipment to
one
1394
input on the
DAC
rear panel.
Also connect the word clock output on your source equipment to the
Wordclock In
connector on
the
DAC
rear panel.
•
Press
the
Input
button repeatedly until
1394
or the source name is displayed (probably
dCS STT
).
The unit may display
Wait ..., No-WClk
or
Search..,
messages if the unit is still settling, then in
sequence
(Clk OK), Locking, DSD
. If you have more than one source connected to the 1394 bus, it
may be necessary to use the
Input
button to select the 1394 source you want to listen to.
Connecting to a Single AES or SPDIF source
Most source equipment (such as CD transports, DVD players) is fitted with a single wire digital output,
usually on an RCA phono connector.
•
Connect your source equipment to the matching input on the
DAC
rear panel using a suitable
cable.
•
Press
the
Input
button repeatedly until your chosen input is displayed. This will be either
AES1,
AES2, RCA1, RCA2, Toslink
or
BNC
.
The
DAC
will lock to the source, displaying in sequence
(44.1k), Locking
,
16/44.1
for example, if the
source is a CD player.
Connecting to a Dual AES Source
Check that your source equipment is capable of Dual AES operation.
•
Connect the AES1 (or AES A) output on your source equipment to the
AES1
input on the
DAC
rear
panel and the AES2 (or AES B) output to the
AES2
input, using two XLR cables. Ensure the cables
are not swapped.
•
Press
the
Input
button repeatedly until both
AES1
AND
AES2
input indicators are lit.
The
DAC
will lock to the source, displaying in sequence
(96k), Locking
,
24/192
for example, if the
source is 24 bit data at 192kS/s.
Connecting to an SDIF/DSD Source
Check that your source equipment is capable of SDIF PCM or DSD operation.
!
SDIF (
S
ony
D
igital
I
nter
F
ace) is not the same as SPDIF (
S
ony/
P
hilips
D
igital
I
nter
F
ace)
and the two are not compatible.
Please ensure that you connect to the correct BNC socket.
•
Connect the CH1 output on your source equipment to the
CH1
input on the
DAC
rear panel and the
CH2 output to the
CH2
input, using two BNC cables. Connect the word clock output on your source
equipment to the
WClk In
connector on the
DAC
rear panel. Ensure the cables are not swapped.
•
Press
the
Input
button repeatedly until
SDIF
appears on the display.
PCM or DSD mode is automatically detected. The
DAC
will lock to the source, displaying in sequence
(44.1k), Locking
,
16/44.1
for example, if the source is a CD player.
DSD
is displayed if the source is
DSD.
Proceed to Step 2.
