Due to the inherent restrictions of the FireWire protocol itself, the FireWire
bandwidth is limited and the capability of the FireWire system depends on
the sample rate.
Below is the maximum number of paths the FireWire is able to handle, set
by sample frequency.
Sample Rate kHz
Maximum number of channels / Bit-rate *
44.1 / 48
96 /
LO
bit-rate
88.2 / 96
48 /
MID
bit-rate
* Achieved using the
FW643
OHCI
chipset on the target computer.
The maximum number of channels is also dependent on the speed of the
DAW computer.
When changing sample rates, the last selection made (for either
Lo
,
Mid
or
Hi
sample rates) will be displayed at the top of the Channel Section of
the screen.
This means it is possible to swap between (for example) 48kHz and
96kHz, and have both sets of settings saved, each set automatically
recalled when the system detects the change in sample rate.
The words
Mid BitRate
or
Lo BitRate
will appear at the top of this screen
to let you know that different limitations apply.
Sample Frequency
u
Select the system sample frequency from the pull-down menu.
If the AD/DA boards are connected to a DAW via FireWire, then the
sample frequency is defined by the DAW and this option will be greyed out
and unavailable.
Sync Source
This selects where Genesys takes its timing source from.
•
Internal -
Genesys will use its Internal clock.
•
Word Clock
– Genesys will lock to the BNC receiving external
Wordclock.
•
If selected, this same Wordclock signal will also be output on all of the
other
Wordclock Out
BNC connectors on the other cards.
•
This means the Genesys AD/DA system can function as a Wordclock
distribution amp.
•
AES Sync
- the system will lock to the AES sync signal carried on the
dedicated XLR on one of the 25-way D-subs. If selected, this same AES
sync signal will also be sent out on another XLR on the same 25-way D-
sub. (See pin-out information starting on page 133 for wiring
information).
•
AES Channel 1/2
- the system will lock to the embedded AES signal
contained on audio channels 1 and 2 of the
D-Line
AES receiver.
The
AES Channel Sync
is taken from the first AES pair of inputs on the
left-most Master card in the console, so therefore taken from Channels
1/2.
If the left-most card in the console is the Monitor card, then
Surround
5.1 DEXT L/R
inputs will be displayed.
Channel Count
If the system detects there is FireWire present, then the FireWire
Channel Count
fuel gauge on the right hand side of the screen will show
