Figure 3 – Front Panel
The dCS 954 uses a combination of front panel buttons for frequently changed
functions and a step through menu for features you might set and forget.
AES1, AES2, AES3, AES4 & BNC
Menu Step
The 5 buttons on the left side of the front panel select the active input(s).
The LEDs above these switches indicate the input status as follows:
LED state Function
Bright Source available and selected.
(More than one for multi-wire.)
Dim Source available but not selected.
Off Source not available.
Flashing Source selected but not available.
do this: Connect the source equipment to the unit as necessary. The unit will
indicate active inputs by dimly lighting the appropriate LED.
do this: To manually select a single input, press the appropriate button, hold it
down for a second then release.
The LED over the button will brighten and the unit will attempt to lock to that
input. The BNC button selects the SDIF input. Note that this can be either SDIF
(2 or 3 if DSD is being used, automatically sensed) or TTL level AES3, under
menu control. See menu commands BNC, BNC I, BNC O on page 26 onwards
do this: To select a Dual AES input on AES1 & 2, press the AES1 and AES2
buttons together, hold for a second and release the AES2 button first.
Similarly for Dual AES on AES3 & 4, press the AES3 and AES4 buttons
together, releasing the AES4 button first.
The two LEDs over the chosen buttons will brighten and the unit will attempt to
lock to the Dual AES input.
do this: To select a Quad AES input on AES1, 2, 3 & 4, press the AES1 & AES4
buttons together, hold for a second and release the AES4 button first.
The four LEDs will brighten and the unit will attempt to lock to the Quad AES
input.
IMPORTANT!
Take extra care when connecting Quad AES as it is very easy to connect the
wires in the wrong order. Although dCS puts messaging in data streams to
allow equipment to sort this sort of problem out itself, not all other
manufacturers do. If there is no messaging in the data stream, the only
indication that this has happened is poor audio quality. Labelling the cables
is a sensible precaution.
