d.4 Pro 4-

These Neutrik “combo” input connectors accept either balanced male XLR connectors, or 1/4" TRS balanced or TS unbalanced connectors. Use XLR connectors for low-impedance microphones, and 1/4" connectors for high-impedance microphones.

The microphone signals entering the d.4 Pro are in for a special treat: the microphone preamplifiers are the Mackie Onyx design, as used in our Onyx line of mixers.

The microphone signals are routed through the mic preamp, EQ section, level control, on/off/talk assign, and then to the main mix bus. Mic signals can also be sent to the aux bus for external processing, before returning to the main mix bus.

These RCA jacks accept a stereo phono-level signal from a turntable (line/phono [5] switch pushed in), or from a line-level playback device such as a CD player or MP3 player (line/phono switch out). Check that your turntable has a phono-level output and a moving magnet cartridge.

5. LINE/PHONO

If you connect a turntable with phono-level outputs to the line/phono inputs [4], push this switch in to select the phono-level input stage. It includes a nice RIAA preamp for proper re-equalization of the incoming phono signal.

2. 48V PHANTOM POWER

If your microphone is a condenser design, it probably requires phantom power to operate. Push in this switch to supply 48 VDC to pins 2 and 3 of the XLR microphone connectors (the 1/4" connectors are not affected).

Dynamic microphones, like Shure’s SM57 and SM58,

 

do not require phantom power. However, phantom

 

power will not harm most dynamic microphones should

 

you accidentally plug one in while the phantom power

 

is turned on. Check your microphone’s user’s manual if

 

you are not sure whether your microphone needs phan-

 

tom power or not.

 

3. CD Inputs

 

The bottom pair of RCA jacks accept a stereo line-lev-

 

el signal from a CD player or other line-level playback

 

device (such as an MP3 player).

d.4 Pro DJ Production Console

If you connect a line-level playback device like a CD or MP3 player, leave this switch out to select the line- level preamp.

Do not press this switch in if you have a line- level signal connected.

6. PHONO GROUND TERMINAL

These terminals are provided to connect a ground wire from your turntable(s) to the d.4 Pro.

Most turntables provide a ground wire to connect to the preamp for the purpose of eliminating “hum” in the audio signal. Simply turn the ground terminal on the d.4 Pro counter-clockwise to loosen it, wrap the end of the ground wire clockwise around the terminal, and hand-tighten the ground terminal for a secure ground connection.
