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.
