Audio Routing - Brainstorm DCD-8 Operation Manual

DCD-8 User Manual

14. Audio Routing

The DCD-8 is able to re-clock an audio input and route it to an audio output. Audio routing is
done through either of the 2 domains. The audio path for Domain A is indicated in Menu 06
and for Domain B in Menu 07.
routed to the corresponding audio connector (AES & S/PDIF, Optical and
is being routed.
Outputs for both domains are set in Menu 05. Domain A input is set in Menu 06 and domain
B in Menu 07. FireWire is set as an insert and is only available in Domain A (menu 06).
WARNING: When routing audio through the DCD-8, the audio is re-clocked. It is impera-
tive that the audio source be synchronous with the domain selected. Otherwise, signal
degradation will occur.
14.1. MAPPING OPTION 1: LEFT TO ODD AND RIGHT TO EVEN
In menu 06 & 07, when selecting a stereo source as the input (AES or S/PDIF), the DCD-8
option, the left channel is routed to channels 1,3,5,7 and the right channel to 2,4,6,8 of
the multichannel outputs (FireWire and the ADAT). Both channels are also routed to all
the stereo outputs (AES or S/PDIF).
14.2. MAPPING OPTION 2: 8 CHANNEL ROUTING MAP
When selecting AES (8 chan) or ADAT as a source, or when inserting FireWire, the DCD-8
uses a routing map as described below. This routing map will vary, depending on the rate
at which the router is running due to the various bit-splitting formats accepted by the DCD-8
(S/MUX and AES double-wire).
