Installation
Dolby® E / D / D plus decoder
C8601
Set the CAN ADDR rotary encoder to an address which is not in use by another module
of a C8000 frame (for details regarding CAN addressing, see C8k system manual).
BUS-EN = OFF will disable the bus driver circuits on power up
SW-1B = ON enables the CAN “+16” address scheme to handle up to 32 modules
SW-1C = not used
SW-1D = not used
Important Note! If the module has an unknown bus configuration, you must set BUS-EN=OFF,
before inserting the module into a C8000 frame. Otherwise you risk to disturbing other
channels of the frame.
When you press the INIT button during power up, it will initialize the module parameters to factory
default values.
status LEDs
On the front panel are 3 status LEDs:
STATUS green = OK
red = bad
flashing = module is in focus of the frame controller (under GUI control)
DOLBY D green = the decoder reads a proper Dolby D / D plus signal
Off = Dolby D decoding error (no Dolby D / D plus signal)
DOLBY E green = the decoder reads a proper Dolby E signal
Off = Dolby E decoding error (no Dolby E signal)
