/from a FireWire device. IMPORTANT NOTES: Use standard 6-pin FireWire 400 cables. • This input is unterminated. If the DCD-8 is the last item in the chain, it needs to be terminated by 3. OPTICAL placing a 75Ω terminator on the loop BNC. -
Page 6: Installation
If the unit has already been used, please refer to page 13 to reset the factory settings. If not, out of the box, the DCD-8 is set to generate a 48KHz Word Clock, referenced to its internal crystal. This rate is fed to all 8 WC outputs, as well as all 5 audio outputs (as silent audio). -

Page 13: 33- Aes Input Default Clock Source
AES or S/PDIF source to use as the clock source. This will be used by the DCD-8 primarily for measurements (frequency & phase). In AUTO mode, the DCD-8 scans through each input and selects the first valid signal it finds. When no AES inputs are connected, status indicates [Scanning]. -

Below are the 7 different possibilities and what they indicate: NO REF Reference missing UNLOCKED Unable to lock... - Page 16 When SETTING the rate of the reference, there is the possibility that the selected rate will not match the measured rate (actual rate). If that is the case, the DCD-8 will still lock to the reference but the output frequency will be adjusted proportionately.

Page 17: Alternate Reference
“HOLDING” in the LCD display. If a signal is still present at the main reference input, the DCD-8 attempts to lock to it again. If it succeeds, it goes through the normal ‘Locked’ sequence; if not, it continues holding and attempts to Lock to the main reference again. -
Page 18: Audio Routing
12.2 on the previous page. 13. Audio Routing One of the features of the DCD-8 is to re-clock an audio input and route it to an audio output. • SELECT AN INPUT: To route audio through the DCD-8, an input must first be selected in menu 06 or 07 (the DCD-8 allows 2 separate inputs to be selected, one for domain A and one for domain B). -

13.2. MAPPING OPTION 2: 8 CHANNEL ROUTING MAP If not selecting ‘Left to Odd/ Right to Even’, 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). -
Page 20: Firewire
DCD-8 should be recognized by your computer as an 8 channel device. The DCD-8 can lock to the clock coming from the FireWire audio and clean it up. It can also re-clock and route audio to and from a FireWire device. -
