Console	Appendix E: FireWire
	System Requirements
	These are the minimum requirements for your com-
Production	puter system to use the d.4 Pro FireWire interface.
	For the PC:
	• Windows XP (service pack 2)
	• Pentium 4 or Athlon XP processor
	•	256 MB RAM
	For the Mac:
	• OS X (10.3.9 or higher)
DJ	•	G4 processor
	•	256 MB RAM
channel	The internal FireWire interface will:
	• Allow multiple streams of digital audio to be
		sent bi-directionally between the d.4 Pro and a
		Mac or PC computer.
	• With all of the streaming choices available, it
-		is possible to make a true multitrack record-
		ing of ALL the different inputs coming into the
4
		mixer’s channels, as well as any audio coming
Pro
		into either of the mic inputs, and keep all of it
		separate for a later mixdown. In addition, with
d.4		the aux and main outputs also going to their
		own tracks, you can have a completed main or
		alternate mix go to the computer, ready for CD
		burning or conversion to MP3s.

• Send MIDI continuous controller and note-on messages to the host computer from the cross- fader.

FireWire stream to computer

The following table shows the outputs to your computer from the FireWire interface inside the d.4 Pro:

To Computer	From
Input 1	PGM 1 L (Line/Phono, or Post-EQ)
Input 2	PGM 1 R (Line/Phono, or Post-EQ)
Input 3	PGM 2 L (Line/Phono, or Post-EQ)
Input 4	PGM 2 R (Line/Phono, or Post-EQ)
Input 5	PGM 3 L (Line/Phono, or Post-EQ)
Input 6	PGM 3 R (Line/Phono, or Post-EQ)
Input 7	PGM 4 L (Line/Phono, or Post-EQ)
Input 8	PGM 4 R (Line/Phono, or Post-EQ)
Input 9	MIC 1
Input 10	MIC 2
Input 11	AUX Send L
Input 12	AUX Send R
Input 13	MAIN Out L
Input 14	MAIN Out R

Each channel of analog audio from the d.4 Pro is converted to digital signals by the FireWire interface’s splendid A/D converters. (The block diagram on page 24 shows the location of the FireWire inputs and outputs.)

Program channel outputs

For the program channels, the point where the FireWire is tapped off, varies with the position of the FW out switch [7]. Refer to figure 1 opposite.

If an FW out switch is in the post-EQ position (out), the computer receives the stereo program pair, post- EQ, and pre-fader. This is a good position to record your vinyl onto the computer, as the levels and EQ can be adjusted for optimal recording levels. The source switch

[30]affects what is playing the program channel and the FireWire output.

If an FW out switch is in the line/phono position (in), the computer receives the stereo program pair, pre-EQ, and pre-fader, independent of the position of the program source switch [30].

Figure 1 on the next page shows a partial block diagram of the signal flow when the switches are set like this:

•FW Out set to line/phono

•Line/Phono switch set to phono

•Source Switch set to FireWire

With the switches set this way, the RIAA phono preamplifier stage re-equalizes and boosts the phono- level signals to line-level, and the routing through the
