Control Panel
The FW-1804's Control Panel is where you can display and adjust settings which determine how the FW-1804 communicates with your computer and other external devices. To open the Control Panel: Windows: Click on Start -> Control Panel and selecting the FW-1804 Control Panel icon. OS X: The FW-1804 Manager can be found in Applications. OS 9: The FW-1804 Control Panel can be found in Control Panels. There are three tabs on the Control Panel: Settings, Routing, and Quick Start. Under Mac OS X, Core Audio tab is in place of Quick Start. greater system stability, and protection against other system activities causing clicks, pops and other audio artifacts. Some experimentation is always required to find the best balance between latency and stability. OVR Threshold This setting determines the level at which the FW-1804's OL indicators register an "over," or clipping level. It can be varied between 0.0 and �5.0 dBFS, in .5 dBFS increments. Compensate for Converter delays (WDM) This setting (Windows only) allows WDM drivers to compensate for converter delays.
Routing Tab Settings Tab
This is where you make the basic settings to configure the FW-1804.
Optical Output Source This menu selects the source of the audio output appearing at the FW-1804's ADAT optical outputs. The selections are: Footswitch Message This is where you select how the FW-1804's footswitch command is interpreted by the host software application. You can choose between FW-1804 Native or Mackie Control emulation protocol. Clock Source This is where you can select the digital clock source. Sample Rate This is where you select the expected sample rate to the FW-1804's digital inputs and the internal sampling frequency. Audio Latency This setting is for selecting the buffer size of the FW-1804's audio performance. The FW-1804's driver temporarily stores input and output audio samples in buffers. Larger buffer sizes will produce higher latencies but will result in ADAT 1:8 - The audio output is determined within your DAW application software. Audio which has been routed to the FW-1804's ADAT outputs within your DAW will appear at the ADAT lightpipe output. Duplicate of Coax Output (TOS) - The audio output is the same as that being sent to the FW-1804's analog outputs L and R, and is sent out the lightpipe in two-channel TOSLINK protocol. This can be useful for sending a twotrack mix to a mixdown recorder equipped with an optical two channel input. Analog Inputs 1:8 - The signal present at the eight analog inputs is routed directly to the ADAT outputs. This is useful in the event you have an analog source that needs to be input to another device that only has ADAT inputs. Coax Output Source This menu selects the source of the audio output appearing at the FW-1804's coaxial digital output. The selections are:
