15. Word Clock
This option will allow you to use a word clock as your sync source.
If no word clock device is connected to the BNC word clock input
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, clicking 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 sampling 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 outputs.
When centered, the signal will be a 50-50 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 gradually 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.

Stand-Alone Mode
The Firefly 808 Universal can work independently, without any
FireWire connection being established. The following is just a
couple of points of interest that you may need to know to use
the Firefly in stand-alone mode.
Firstly, whatever settings you have made in regards to digital
inputs, outputs, and sampling rates while using the Firefly 808's
mixer software will be kept even after you restart the device and/
or disconnect the FireWire /USB cable. This means whatever
inputs and outputs you have set will be activated/deactived as
per your previous settings. The default sampling rate is 44.1
kHz, and the default digital input/output is S/PDIF.
Also, the analog inputs are routed to their corresponding analog
outputs, as well as a mix of these inputs being sent through any
digital outputs that have been set (ADAT, S/PDIF, etcetera).
