d.4 Pro 4-channel DJ

14. RCA MAIN OUTS

These RCA connectors provide an unbalanced line- level signal from the main mix, either pre- or post-main level [55] control, depending on the setting of the live/record [15] switch. You can connect these outputs to a tape deck with RCA inputs, such as a standard consumer deck, or to computer audio line-level inputs (if you do not have a FireWire port on your computer).

15. LIVE/RECORD

When this switch is out (live position), the RCA main outs [14] provide the signal just after the main level

[55]control, so it essentially provides the same signal as the XLR main outs [12], except it is an unbalanced signal rather than a balanced one.

When this switch is pushed in (record position), the RCA main outs provide the signal just prior to the main level control. This allows you to make a stereo recording that is not affected by main level changes during a performance.

16. POWER

When the power switch is turned on, power is supplied to the d.4 Pro, and the EQ knobs will light up.

As a general rule, turn on the d.4 Pro first (before your amps), and turn it off last. This will reduce any turn-on, or turn-off thumps.

17. POWER RECEPTACLE

This is a standard 3-prong IEC power connector. Connect the detachable linecord (included in the box with your d.4 Pro) to the power receptacle, and plug the other end of the linecord into an AC outlet.

The d.4 Pro has a universal power supply that accepts any AC voltage from 100 VAC to 240 VAC. It will work virtually anywhere in the world. It is less susceptible than conventional power supplies to voltage sags or spikes, providing greater electromagnetic isolation and better protection against AC line noise.

18. FIREWIRE Connections

These identical FireWire connectors are used for transferring digital audio to and from your laptop computer or digital audio workstation. Use either one to connect to your computer. The other one can be used to connect other FireWire devices.

The internal FireWire interface provides a total of 14 audio outputs to your computer, including:

•Main mix outputs L/R

•Aux sends L/R

•Microphone output 1 and 2

•Post-EQ (or line/phono) program 1 output L/R

•Post-EQ (or line/phono) program 2 output L/R

•Post-EQ (or line/phono) program 3 output L/R

•Post-EQ (or line/phono) program 4 output L/R

The block diagram on page 24 shows the points where FireWire signals enter and leave the mixer.

The main mix output signals are pre-main level [55], so they are independent of any adjustments made to the main level. This allows you to easily record your live performance directly to your laptop.

The FireWire interface also lets you use your computer to playback music through the d.4 Pro. It provides a return for four stereo pairs:

•Program 1 input L/R

•Program 2 input L/R

•Program 3 input L/R

•Program 4 input L/R

These program inputs can be selected using the source select [30] switch on each program channel. See page 26 for more FireWire details.
