Control Panel
SPDIF 1:2 - The audio output is determined within your
DAW application software. The FW-1804's S/PDIF outputs
are seen as separate outputs within your DAW application.
With this setting, audio which has been routed to these out-
puts appears at the FW-1804's two-channel digital outputs.
Monitor Mix 1:2 - The audio output is identical to that
being sent to the FW-1804's
STEREO OUT . This is useful
if, for example, you wish to send the stereo mix you are
monitoring to a two channel digital mixdown recorder.
Note that the
MONITOR control does not affect the coaxial
output in this case.
SPDIF Input Routing
This menu selects the source of the audio input appearing at
the FW-1804's two-channel digital (D IN) inputs. The
selections are:
COAX to SPDIF 1:2 - The digital audio signal being input
to the FW-1804's coaxial digital input is routed to the two-
channel digital (D IN) inputs.
Optical to SPDIF 1:2 - A two-channel digital audio signal
in TOSLINK format, being input to the FW-1804's optical
digital input, is routed to the two-channel digital (D IN)
inputs. (Note that the ADAT inputs will not be available to
your DAW application if you use the optical input connec-
tor in TOSLINK mode.)
Quick Start Tab (Windows only)
This allows you to specify a set of channels which will
always stream when using WDM/KS Driver Mode in
SONAR.
This, for example, speeds up the start of a playback or
record operation in SONAR, especially when there are a lot
of channels enabled. If there is a hesitation after pressing
PLAY
or
RECORD
before the operation begins, try
enabling this feature.
To use it, check the channels that you will be using in your
WDM audio app. When the channels selected in the Quick
Start tab match the channels actually used by your applica-
tion, the FW-1804 will not have to re-sync when the appli-
cation begins to use those channels. This has shown to be
much faster, and less prone to produce an "audio engine
stop" message.
Core Audio Tab (Mac OS X only)
In OS X, you can specify how the FW-1804 should appear
to the operating system:
The options available are as follows:
An 18-Input/12-Output Sound Device
All input and output channels are used. The S/PDIF input
channels become channels 17 and 18, and the S/PDIF out-
put channels become two output channels in addition to the
ADAT and monitor outputs.
An 8-Channel Sound Device
Select either the analog input channels or the ADAT input
channels. The outputs are the analog monitor outputs or the
ADAT outputs. Note that the ADAT output level is not
controlled by the front panel
MONITOR
control.
A 2-Channel (Stereo) Sound Device
Select any pair (1-2, 3-4 etc.) of inputs as the input pair.
Select any pair of outputs as the output pair. Note that only
the stereo analog outputs are controlled by the front panel
MONITOR
control.
TIP
In order to optimize the load on your CPU, you should con-
figure the FW-1804 for your situation. If you are making a
live stereo recording using the FW-1804, there is little point
in configuring an 18-in/12-out device, for example.
