Direct control of each individual fader and the learning of manual adjustments are possible. Revision #03 Editware Technical Note Page 2 of 7 02/07/2003 Fastrack VS and the Yamaha 03D Audio Mixer Interconnect Cable An interconnect cable can be constructed using a PS-2 mouse/keyboard plug and wire and a Serial RS-422 female connector. This cable connects between the HOST port on the Yamaha O3D and a serial (male-male) cable attached to the Fastrack serial breakout (or use a male connector if your cable is long enough to reach the Fastrack serial breakout). Since the numbering on PS-2 connectors varies or is frequently missing, please refer to the letter positions noted here for the PS-2 plug (the 9-pin conforms to standards). Both 9-pin connector and PS-2 plug are viewed from the front. Note: The jumper between the top two pins on the PS-2 plug is essential for status reporting from the 03D mixer to Fastrack so it can learn manual changes to fader levels. Serial 9-pin PS-2 plug 2 E 7 F 3 A 8 B C therefore, all audio previews should be done utilizing this preview switcher in the 03D. Set each sources BUS Out and monitoring in the PAN/ROUTE section as below for four channels per source: The BUS Outputs (1-4) are fed to the RECORD device for recording (or AES Out if the YGADI option is installed) and the MONITOR OUT connected to amplifier and speakers. The ST OUT is the signal that is monitored on the MONITOR OUT (when set in Bus to ST to OFF not highlighted), allowing preview monitoring to be controlled via the 03D mixer. The MONITOR OUT has a volume control knob for convenient speaker volume adjustment. Revision #03 Editware Technical Note Page 5 of 7 02/07/2003 Fastrack VS and the Yamaha 03D Audio Mixer AUDIO MIXER FILES The specific mixer protocol files to be used on the Assignment Page Shift+Assign are in the MIXER folder on the C:/ drive of the Fastrack computer, in the Ftruntime folder. The 2 channel (stereo) version of the 03D driver is labeled 03D_2CH.MIX and has only two differences from the 4 channel version: Name=03D_2 and the FaderCount=2. The 03D_4CH.MIX protocol will have Name=03D_4 and a FaderCount=4 Revision #03 Editware Technical Note Page 6 of 7 02/07/2003 Fastrack VS and the Yamaha 03D Audio Mixer FASTRACK VS SETUP Assign the following audio Start and Count values in the Source Assignment page SHIFT+ASGN in Fastrack VS for the 03D setup (two channels per device in this example): Note: Under Audio Mixer (upper right), the two columns represent the Start number for the first fader of each source, and the count for each source (1=mono, 2=stereo, 4, etc). Assign the following audio Start and Count values in the Source Assignment page SHIFT+ASGN in Fastrack VS for the 03D setup (four channels per device in this example): Note: Notice the different TYPE of audio mixer selected. 03D_2CH.MIX for stereo, 03D_4CH.MIX for four channels of audio. The Events on each Fastrack track will have only two channels with the 2CH file, and four channels with the 4CH file.
