Sync Source
12. Device
Pushing this will allow you to use the Firefly 808 Universal
as the sync source for all your digital gear.
13. Coaxial S/PDIF
Selecting this option will activate any coaxial S/PDIF de-
vice as the sync source for your digital gear. If no device
is connected to the S/PDIF input on the Firefly 808, the
corresponding sync source LED on the face of the de-
vice will flash briefly then return back to the previously
selected sync source.
14. Optical S/PDIF
Selecting this option will activate any optical S/PDIF de-
vice as the sync source for your digital gear. If no optical
S/PDIF device is connected to the TOSlink ADAT input on
the rear of the Firefly 808 Universal, the corresponding
sync source LED on the face of the device will flash briefly
then return back to the previously selected sync source.
15. Word Clock
This option will allow you to use a
word clock as your sync source.
If no word clock device is con-
nected to the BNC word clock in-
put on the rear of the Firefly, then
the corresponding sync source
LED on the face of the mixer will
flash briefly and then return back
to the previously selected sync
source. Please see the diagram
below for information on hooking
up a world clock as your sync
source.

16. PC
This is the default option, and allows you to use the PC
as the sync source. When set to PC, the corresponding
sync source LED on the front of the Firefly 808 Universal
will light up.
Note: If ADAT and S/PDIF devices are not set to the same sync source,
the user will be prompted to correct the problem.
Digital I/O Select
17. S/PDIF
Selecting this option will allow you to use a S/PDIF or AES
enabled digital device with the Firefly.
18. High Speed S/PDIF
If you connect a high speed S/PDIF product to the S/PDIF
connector on the rear of the Firefly 808 Universal, click-
ing this option will allow you to use the output signal from
this device.
19. ADAT
Select this option to use the TOSlink ADAT inputs on the
rear of the Firefly 808 Universal.
20. SMUX
By selecting SMUX as your digital input/output device,
you are able to connect a SMUX enabled product to the
"ADAT" TOSlink inputs of the Firefly. The SMUX output
signal is typically 8 channel, however if you set the sam-
pling rate to 96 kHz, this is reduced to 4 channels.

Other Features

21. Sampling Rate Selection
Here you can select the sampling rate of the signal sent
to the computer. For most applications, you will be able to
select between 44.1, 48, 88.2 and 96 kHz. If you choose
ADAT as your digital input selection, you are then able
to select 44.1 kHz or 48 kHz. When using high speed S/
PDIF devices, you are able to select between 176.4 and
192 kHz sampling rates. If the 192 kHz sampling rate is
set, the Firefly's level meter will be disabled.
22. Crossfader
The mixing software's crossfader allows users to adjust
the signal returned to the computer's analog 1 and 2 out-
puts. When centered, the signal will be a 0-0 mix of
the pure signal received by the Firefly 808 Universal and
the signal returned to the 808 from the computer. When
pulled to the left, the monitor signal from the 808 gradu-
ally becomes more dominant; when pulled all the way to
the left, this signal is the only signal audible. If this control
is pulled to the right, however, the stereo signal from the
mixing panel software will become more dominant.
