DCC2 User Manual
Function Switches and Indicators
Power
The main power switch is on the back of the unit. The chrome power button on the front
is a momentary switch that toggles the operation between power on and power save
mode every time the user pushes it. During the power save mode the remote control and
all front panel functions become inactive.
Clock Control Section
LOCK: This indicator is lit when the unit detects valid clock at the selected
digital audio input. For normal operation with digital audio inputs this
indicator has to be lit or else all audio outputs will be muted. For
normal operation with analog audio inputs this indicator will stay off
and all audio outputs are unmuted.
EXT CLOCK:
Selects external clock input when lit. The actual clock input is then
determined by the selected digital input. This switch controls the
“Master” and “Slave” operation as explained in more depth later in
this manual. For Master operation this switch has to be turned off,
and for Slave operation it has to be turned on.
44.1kHz / 48kHz: These buttons select the base frequency for the selected digital
audio input. For instance, for all digital inputs with sample
frequencies of 44.1kHz or 88.2kHz the switch 44.1kHz has to be
selected, for all digital inputs with sample frequencies of 48kHz or
96kHz the switch 48kHz has to be selected.
Analog Output Section
POLARITY: When this switch is lit the polarity of all analog outputs is inverted.
WIDE / NARROW: These switches are only active when a digital audio input source is
selected and are inactive for analog input sources. When NARROW
bandwidth is selected the analog outputs are lowpass filtered to limit
the amount of signal content above 30kHz. The WIDE mode selects
a much wider bandwidth and should be used in most cases.
MUTE:
When lit all outputs are muted. Pushing the button again unmutes
the outputs.
Analog, DSD and PCM Input Sections
These 8 switches select the input source with associated clock.
XLR: Balanced analog line input from the XLR connectors. Optionally this
input can be configured for unbalanced inputs with a toggle switch on
the rear panel besides the XLR connectors.
RCA:
Unbalanced analog line input from the RCA connectors.
DSD - BNC:
DSD digital input from the BNC connectors. Either RAW-DSD or
SDIF-3 can be used (auto detection).
DSD – ST:
EMM OptiLink for direct connection to EMM Labs transport.
