Occupational Safety and Health Administration (OSHA) has specified
the permissible noise level exposures shown in the following chart.

According to OSHA, any exposure in excess of these permissible limits

could result in some hearing loss. To ensure against potentially danger
ous exposure to high sound pressure levels, it is recommended that all
persons exposed to equipment capable of producing high sound pres
sure levels use hearing protectors while the equipment is in operation.
Ear plugs or protectors in the ear canals or over the ears must be worn
when operating the equipment in order to prevent permanent hearing
loss if exposure is in excess of the limits set forth here.

instructions on page 2, and this page
before you begin using the d.4 Pro
mixer.

Zero the Controls

1. Turn the rear panel power switch off.

2. Turn down the level and aux controls for mic, pro
gram 1, 2, 3 and 4, and center all EQ controls.

3. Set all push button switches to their “out” positions.

4. Set the mic assign switches to off, and program as
sign knobs to off.

5. Turn down the level
zone, and phones.

6. Set the program faders fully down.

7. Center the crossfader.

Set the Levels

To set the level controls, it’s not even necessary to
hear what you’re doing at the outputs of the mixer. To
listen while you work, plug headphones into the front
panel headphone jack, press the program’s cue button,
and set the phones level knob up just a little.

1. Select the input using the program source switch.

2. Play something into the selected input, at the nor

mal source volume.

3. With the program fader down, there will be no

output, but the program meter will still work.

4. Adjust the channel’s rotary level control so that the

LEDs on the program meter stay around “0” and +6,
and never go higher.

5. Apply some EQ if needed, (return to step 4 if you

do, just to check the levels are still OK).

6. Repeat for the other channels.

Set the Mic Levels

1. To level the microphone input, keep the mic assign

switch off, and sing at your highest expected level.

Connections

If you already know how you want to connect the d.4
Pro, go ahead and connect the inputs and outputs up. If
you just want to quickly get sound through the d.4 Pro
mixer and try it out, follow these steps:

1.

Plug a signal source to the d.4 Pro. This could be a:

• Microphone into a mic input

• Turntable with phono-level output into a phono
input (rear line/phono switch in)

• Line-level source such as a CD player into the
phono input (rear line/phono switch out)

• Line-level source such as a CD player into a CD
input.

2.

Connect cords from the d.4 Pro’s main outs (XLR or
RCA connectors on the rear panel) to your powered
speakers or amplifier.

3. Plug in the detachable linecord, connect it to a live
AC outlet, and turn on the d.4 Pro’s power switch.

2. Adjust the mic level until the OL LED above it only
comes on occasionally.

Instant Mixing

1.

To get sound out of the speakers, set the program
assign knob to main, turn up the program fader,
slowly

rotate the main level control to a comfortable

listening level.

2. Sing and play. You’re a star!

3. With other channels in use, you can assign one to A,
one to B, and play with the crossfader.

4. You can also add filter X or Y to each program chan
nel, and adjust the filter parameters.

and

FireWire

1. See Appendix E, page 26 for exciting details of get­ting started with FireWire.

1. MIC Inputs

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.

4. LINE/PHONO Inputs

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.

1

. 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 phan­tom power or not.

. CD Inputs

The bottom pair of RCA jacks accept a stereo line-lev­el signal from a CD player or other line-level playback
device (such as an MP3 player).

10

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 line­level preamp.

Do not press this switch in if you have a line­level signal connected.

. 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.

7. FW OUT

These switches affect how the program channels send

their discrete signals to the internal FireWire interface.

Use these to connect to a pair of powered monitors in

Owner’s Manual

the booth (or to the inputs of an amplifier powering pas­sive monitors). Use the booth level [52] control on the
top panel to adjust the level.

In the post-EQ position (out), the channel sends its
signal to the internal FireWire interface after it has
passed through the EQ section. Its level will be affected
by the settings of the channel source [30] selector,
input level [29], and EQ controls. Use this position to
record via FireWire from a channel, as you can adjust
the level and EQ for optimum recording.

In the line/phono position (in), the channel signal
to the FireWire card comes directly from the phono or
line input, whichever is selected by the line/phono [5]
switch. The FireWire signals are taken after the phono
preamplifier, but before the channel’s source selector,
input level controls, EQ, or channel fader [38]. FireWire
sends audio to your computer, independent of the posi­tion of the program source switch. In this way, you are
not tying up extra channels; you can send a signal out to
your computer, process it with your software, and have it
come back in on the same channel as an ordinary input.

Use the line/phono position if you are using
timecode vinyl (see page 27). You can then
set up a virtual turntable on your computer,

that is controlled by the actual turntable.
Drop any music tracks onto the virtual turntable and
scratch away like it was a record. The output can then
come back into the same program channel, and play in
the main mix.

8. AUX SEND

These 1/4" TRS jacks provide a balanced line-level
output signal from the stereo aux send bus. Typically,
you would use these outputs to connect to the inputs of
an external effects processor. You can also use an unbal­anced 1/4" TS cable to make this connection.

9. AUX RETURN

These 1/4" TRS jacks accept a balanced line-level
signal from an external effects processor. They will also
accept an unbalanced 1/4" TS connector.

If you only have one monitor, just use one of the out-

puts and push in the booth stereo/mono [53] switch.

11. ZONE Outputs

These 1/4" TRS jacks provide a balanced line-level
signal from the main mix bus, prior to the rotary main
level [55] control or pan [56]. Use these to connect to a
pair of powered monitors in a second zone. Use the zone
level [54] control to adjust the level.

The zone and booth outputs are the same, except the
zone does not have a stereo/mono switch, and its level is
set by the zone level control.

1. XLR MAIN OUTs

These male XLR connectors are the outputs of the
main mix. They provide a balanced microphone-level or
line-level signal from the main level [55] control. The
line/mic [13] switch determines if it is a mic-level or
line-level output. If they are set to line-level, connect
these to the balanced inputs of your active speakers, or
power amplifier(s) powering your main speakers. If they
are set to microphone-level, you can connect them to a
mixer’s microphone inputs.

If you are connecting the d.4 Pro main output to an
unbalanced input, use the RCA main outs [14] instead.

Balanced connections offer better immunity
to external noise (specifically, hum and buzz)
than unbalanced connections. Because of

this, it is the preferred interconnect method,
especially in cases where very long lengths of cable are
being used. A long unbalanced cable carries with it more
opportunity for noise to get into the system — having
balanced cables means very little noise will enter the
system. If you must use an unbalanced connection, keep
the cable length to 10 feet or less (3 meters).

1. LINE/MIC

If you are using a stereo effects processor, connect its
left and right outputs to the corresponding left and right
Aux return jacks. If it is a mono effects processor, con­nect its output signal to the left aux return jack, and it
will appear on both the left and right main mix bus.

10. BOOTH Outputs

These 1/4" TRS jacks provide a balanced line-level
signal from the main mix bus, prior to the rotary main
level control [55] or pan [56].

If you are connecting the XLR main outs [12] to line­level inputs like a power amplifier’s inputs, leave this
switch out, in the line position.

If you are using the d.4 Pro as a submixer and con­necting the XLR main outs to the mic inputs of another
mixer, push this switch in to the Mic position. This
reduces the output signal to a microphone level, and

14. RCA MAIN OUTS

These RCA connectors provide an unbalanced line­level 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

d.4 Pro 4-channel DJ Production Console

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.

1. 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

9

16

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:

This is a standard 3-prong IEC power connector.

with your d.4 Pro) to the power receptacle, and plug the
other end of the linecord into an AC outlet.

MIC Input Section

There are two completely independent microphone
preamplifiers, arranged in vertical columns. The left col­umn controls mic input 1, and the right column controls
mic input 2. Each section contains a most wonderful
Mackie Onyx premium-quality microphone preamplifier.

19. LEVEL

These knobs adjust the gain of the mic preamps for
any mics plugged into the mic [1] input jacks. The gain
is adjustable from 0 (unity gain) up to +60 dB of gain.
Adjust the knobs so that the loudest speaking or shout­ing into the microphone just barely lights the OL LEDs
[21]. This gives the best signal-to-noise ratio for the
microphone preamp.

0. SIG LEDs

These LEDs act as signal present indicators. They
light when the microphone signals reach –20 dBu, to
give you a clue that the microphones are working.

These knobs give your mic signals up to 15 dB of boost
and cut, at 12 kHz and above. At the center position
U (unity gain), there is no effect on the signal. (If all
three EQ controls are set to minimum, the mic signals
are attenuated –15 dB across the audio range.)

4. MID EQ

These knobs give your mic signals up to 15 dB of boost
and cut, at 2.5 kHz, with no effect at position U.

5. LOW EQ

These knobs give your mic signals up to 15 dB of boost
and cut, at 80 Hz and below, with no effect at position U.

. AUX

These knobs allow you to adjust how much of the mi­crophone signal goes onto the aux bus (wet), and how
much goes to the main mix (dry).

Wet: Mic signals only go onto the aux bus.

Dry: Mic signals only go onto the main mix bus.

Middle position: Mic signals are split evenly between
the aux and main mix.

“Wet” is a term used for signals that have passed
through an audio processor, such as an external
valvezilla-warmulator 2000. “Dry” is a term used for
signals thankfully not passed through such a processor.
So this control lets you finely adjust the amount of vocal
loveliness available for external processing, and how
much is available unprocessed for the main mix.

Note: Always set these controls to dry if you
do not want to add mics to the aux loop for ex­ternal processing. Otherwise your mic signals
to the main mix will be attenuated.

This control does not affect the mic direct FireWire
outputs to your computer.

1. OL LEDs

These light when the microphone signals reach 3 dB
below clipping. It’s okay if they blink occasionally, but
if they are blinking frequently or are lit continuously,
turn down the level [19] controls until they just blink
occasionally.

7. MAIN

These knobs allow you to adjust how much of the mi­crophone signal goes onto the main mix bus. It also af­fects the mic signals reaching the aux bus and FireWire.

0. SOURCE

This switch selects one of three possible input sources
for each program channel:

• FireWire: The signal coming in from your com
puter via the internal FireWire interface.

• Line/phono: The signal from a turntable or a
line-level playback device coming from phono
input [4]. (Depending on the setting of the
rear-panel line/phono [5] switch.)

• CD: The signal from a CD or any other line-level
device connected to the CD input [3].

You can have signals coming in on all three in­puts, and quickly change between them using
this heavy duty switch. Although the d.4 Pro

is a four channel mixer, this three-position
source selector for each channel allows you to select up
to 12 different sources without repatching!

-

1. HIGH EQ

8. MIC ASSIGN

In the on position, the microphone signals are sent
to the main mix bus (equally left and right), without
affecting the level of your other program sources.

In the off position, the mic will not be heard.

In the spring-loaded, momentary talk position, each
program channel is reduced by 14 dB, so you can eas­ily make your exciting mellow-toned announcements.
When released, the program channels return to their
original volume after a short delay..

The mic output to FireWire is not affected by the posi­tion of this switch.

This knob gives you up to 10 dB of boost at 4 kHz and
above, and turns off the signal at 4 kHz and above when
the knob is turned to the kill position. At the center
position U, there is no effect on the signal.

Note: When all three EQ knobs are turned to the kill
position, the signal is effectively muted and no signal
passes through to the output.

. MID EQ

This knob gives you up to 10 dB of boost at 1 kHz, and
turns off the signal at 1 kHz when the knob is turned
to the kill position. At the center position, there is no
effect on the signal.

. LOW EQ

This knob gives you up to 10 dB of boost at 300 Hz
and below, and turns off the signal at 300 Hz and below,
when the knob is turned to the kill position. At the cen­ter position, there is no effect on the signal.

d.4 Pro DJ Production Console

4. FILTER SELECT

This three-position switch allows you to pass the
program material through either of two filters before
reaching the main mix bus (not the aux bus.)

• In the top position, the program passes through
filter X, whose parameters are adjustable using
the controls in the bottom left of the mixer.

• In the middle position, the program is not sent
through a filter, just straight through the pro­gram channel.

• In the bottom position, the program passes
through filter Y, whose parameters are adjust­able using the controls in the bottom right of
the mixer.

As the filter X controls are located in the bottom left,
you could use it on programs assigned to the left (A)
side of the crossfader [43]. Similarly, you could use
filter Y on those assigned to the right (B) side. This is
just an idea, so try whatever works for you.

If you want the aux signals to be affected by

Owner’s Manual

filters X and Y, as well as the external proces­sor, then you could do the following:

If a program is playing in program channel 1, you
could set its aux level to wet. The aux send [8] output
would feed your external processor. The output from
your processor could then return to the input jacks of
another program channel, such as program 2’s CD input
[3], set its aux to dry and assign filter X or Y to it. In
this way, your program 1 is then externally processed
and reappears into program 2 for the filtering and then
onto the main mix.

. CUE

Press this button in to route a copy of the program
channel (pre fader) to the cue bus, also known as the
PFL (pre-fader-listen) bus. You can then listen to the
program in your headphones, getting it ready before
increasing the program fader and assigning it to the
main mix.

Filters X and Y wish to remain anonymous, and their
real names have been changed as part of the filter pro­tection program.

5. AUX

These knobs allow you to adjust how much of the
stereo program signal goes onto the aux bus (wet), and
how much goes to the main mix (dry).

In the wet position, the stereo program signals only go
onto the aux bus.

In the dry position, the program signals only go onto
the main mix bus.

In the middle position, the program signals are split
evenly between the aux and main mix.

“Wet” is a term used for signals that have passed
through an external audio processor. “Dry” is a term
used for signals not passed through such a processor. So
this control lets you adjust the amount of program avail­able for external processing, and how much is available
unprocessed for the main mix.

The aux bus contains a mix of the aux signals of all
program and mic channels that have their aux controls
set to more than dry.

The aux bus is then adjusted using the aux send [40]
control, and sent out to FireWire and the aux send [8]
TRS outputs, typically to an external effects processor.

The aux signals are affected by the settings of the
program source [30] switch, level [29], EQ [31, 32, 33],
program fader [38], and crossfader [43]. They are not
affected by filter X or Y.

The cue signals are post-EQ, but pre-fader [38], and
the program meter [39] shows the levels dancing along
happily.

Turn down the phones level [50] control
every time before cueing, or you may be in for

a loud and painful surprise. Check the pro­gram meters, as these show the program level coming
your way.

7. ASSIGN

This four-position stereo rotary switch affects the

program in four popular ways:

• A

Moving the crossfader [43] towards the left

will increase the level of any programs set to A.
(At the same time, decreasing the level of any
programs set to B.)

• B

Moving the crossfader towards the right will

increase the level of any programs set to B.
(At the same time, decreasing the level of any
programs set to A.)

• Main

The program level is not affected by the cross

fader.

• Off

The program channel is effectively muted, and

does not appear on the main mix.

The program faders [38] and the crossfader

After the audio signals pass through the EQ
section they enter a pair of VCAs (voltage controlled
amplifiers). These control how much of the audio signal
is sent out into the filters (if selected) and then to the
main mix bus. The audio output level from the VCAs is
adjustable by a control voltage, and the assign switch
selects what will affect the control voltage:

9. PROGRAM LEVEL METERS

These meters have 12 LEDs, calibrated in dBu, rang-

ing from top to bottom: OL, 15, 10, 6, 3, 0, -2, -4, -7, -10,

-20, and -30

They indicate the summed-mono signal strength of
the program signals, after the program input level [29]
control, and EQ, but not affected by the program fader
[38] or the crossfader [43].

• If it is set to A or B, then the VCA control

voltage is set by the position of the crossfader
and the program fader.

• If it is set to main, then only the
has an effect.

• If it is set to off, then the VCA output is muted.

• In addition, all program levels are attenuated
by 14 dB when a mic assign [28] switch is set to
“talk” to make a brief announcement.

program fader

8. PROGRAM FADER

This controls the volume of the program signal being

sent to the main mix bus.

These faders are designed to last the lifetime of the
d.4 Pro. No audio passes through these faders, rather,
they send a control voltage to a pair of VCAs that deter­mine the gain of the signal. This is a very good thing, by
the way, as the audio will not be affected by any scratchy
electrical contacts.

Typically, you want to see these meters bouncing
between the “0” and the “+6” LEDs. It is okay if the OL
LED lights occasionally, but if it lights frequently or con­tinuously, turn down the program level controls (or the
EQ) until the OL LED blinks occasionally or not at all.

Occasionally, the meters will start decoding
vinyl timecode messages from a small blue
methane DJ planet in Ursa Minor. This is
perfectly normal, do not be alarmed.

Aux, Crossfader, and Filter Controls

40. AUX SEND

This knob controls the amount of signal being sent
to the aux send [8] outputs from the aux bus. Adjust
this knob to provide an appropriate input signal level to
your external effects processor (or whatever you have
connected to the aux sends). It ranges from off, to unity
gain at maximum.

l done.

4. CROSSFADER CONTOUR

Use this to adjust how fast or slow the crossfader [43]
responds to movement.

In the slow position, the crossfader responds in a
linear fashion, increasing from A to B at the same rate
across its length of travel.

In the fast position, the crossfader responds logarith­mically, increasing from A to B very quickly, and then
changing very little for the remainder of the fader’s
travel.

In the fast position, crossfading occurs within
the first 5 mm of luxurious fader travel. This
is useful for cutting, where you can mix a

scratch over existing program material. In
this style, you can keep the fader either at the complete
edge of the fader’s travel, or only a very small amount
from that, and a very steep fade slope is desired. Then
you can quickly “crab” the fader to cut the scratch signal
into the program signal.

Adjust the control between the two extremes to get

the crossfader response that works best for your style.

44. FILTER TYPE

Each program has a filter [34] switch that allows you
to choose if the program goes through a filter (X or Y)
before the program is added to the main mix.

This 4-position rotary switch allows you to choose the
filter type, or bypass it:

• HP (high-pass): Frequencies below the
frequency setting are attenuated.

• BP (band-pass): Frequencies either side
filter frequency setting are attenuated.

• LP (low-pass):
frequency setting are attenuated.

• BYP (bypass): No filter is inserted into the
signal

The signal level of programs assigned to A or B by

the d.4 Pro with no degradation in quality.

The sensitivity of the travel can be adjusted using the
crossfader contour [42] control.

This allows you to adjust the filter’s frequency, with a

range between 40 Hz and 16 kHz.

For example, if you want a filter that drops off the

and adjust the frequency to 80 Hz.

You might find it fun to set the resonance, then rotate
the frequency while using the bump switch (see below)
to cut the filter in and out. The filter controls are posi­tioned closely to allow this easy kind of DJ play.

This controls the output level of the headphone am­plifier. The range of the knob is off to +12 dB.

WARNING: The headphone amp has enough
gain to drive any standard headphones to

a very loud level. We’re not kidding! It can
cause permanent hearing damage. Even intermediate
levels may be painfully loud with some headphones. BE
CAREFUL! Turn this all the way down before connect­ing headphones, and before you press cue [36] on any
program, or make any connections. Keep it down until
you’ve put on the headphones.

51. PHONES JACK

This front-panel 1/4" TRS stereo jack is where you

plug in your stereo headphones.

The main headphone volume is controlled by the
phones level [50] control. The level is not affected by
the main level [55] or pan [56] controls. As mentioned
above, pressing split cue [49] gives the cue mix in one
ear, and the main mix in the other. The phones source
control [48] adjusts the cued source, or main mix to
play in your headphones.

Appendix A: Service Information

Warranty Service

Details concerning Warranty Service are spelled out in
the Warranty section on page 31.

If you think your d.4 Pro has a problem, please check
out the following troubleshooting tips and do your best
to confirm the problem. Visit the support section of our
website (www.mackie.com/support) where you will find
lots of useful information such as FAQs, documentation,
and user forums. You may find the answer to the prob­lem without having to send your d.4 Pro away.

Here are some things you can check:

Troubleshooting

No Power

• Our favorite question: Is it plugged in?

• Make sure the power cord is securely seated in the

IEC socket [17] and plugged all the way into the
AC outlet.

• Make sure the AC outlet is live (check with a tester

or lamp).

• Make sure the rear panel power switch [16] is in

d.4 Pro 4-channel DJ Production Console

the on position (up).

• Are the EQ controls on the front panel illuminated?

If not, make sure the AC outlet is live.

• Are all the lights out in your town? If so, contact

your local power company to get power restored.

• If no LEDs are illuminated, and you are certain that

the AC outlet is live, it will be necessary to have
your d.4 Pro serviced. There are no user serviceable
parts inside. Refer to “Repair” on the next page to
find out how to proceed.

• Is the correct input chosen with the source [30]
switch, and is its program level [29] turned up far
enough?

• Try the same source signal in another channel, set
up exactly like the suspect channel.

• Make sure the aux knob [35] is turned to fully dry
if you are not using an external processor.

Bad Output

• Is the associated level control (if any) turned up?

• If it’s one of the main outputs, try unplugging the
others. For example, if it’s the left XLR main out
[12], unplug the left RCA main out [14]. If the
problem goes away, it’s not the mixer.

• If a left output is presumed dead, switch the left
and right cords at the mixer end. If the problem
stays on the left side, it’s not the mixer.

Bad Sound

• Is the input connector plugged completely into the
jack?

• Is it loud and distorted? Make sure the input level
[29] control is set correctly. Reduce the signal level
on the input source if possible.

• If possible, listen to the signal with headphones
plugged into the input source device. If it sounds
bad there, it’s not the d.4 Pro causing the problem.

• If you are using a turntable with a phono-level
output, and the sound is low and distorted, check
that the line/phono [5] switch is set to phono. Note
that the phono section requires your cartridge to be
a moving magnet type. It may be too low to amplify
the low levels of a moving coil type.

Bad Channel

• Check the assign switch [37] is not in the off posi­tion.

• Check the channel’s program fader [38] is not fully
down.

• Are that channel’s EQ controls all turned down?

• Is the signal source turned up? Make sure the
signal level from the selected input source is high
enough to light up some of the program meter [39]
LEDs.

0

d.4 Pro DJ Production Console

Noise/Hum

• Turn down the aux return [41] knob. If the noise
disappears, it’s coming from whatever is plugged
into the aux returns [9].

• Check that your turntable’s audio ground wire is
connected to the phono ground [6] terminals.

• Turn down each channel, one by one. If the noise
disappears, it’s coming from whatever is plugged
into that channel. Check your whatever.

• Check the signal cables between the input sources
and the d.4 Pro. Disconnect them one by one. When
the noise goes away, you’ll know which input source
is causing the problem.

• It often helps to plug all the audio equipment
into the same AC circuit so they share a common
ground.

Recording to FireWire

• If you are recording vinyl music to your computer,
and the level seems low, set the FW out switch
[7] in the out position, so the FireWire outputs
come after the level and EQ sections. This will give
you the chance to boost the levels with the level
controls [29]. Set the source select switch [30] to
line/phono, and the line/phono switch [5] to phono.

• If you are using timecode vinyl or timecode CD,
then press in the FW out switch, so the Firewire
outputs come directly after the phono section. In
this way, you can have the timecode flowing to your
computer, and use the source selector switch to
play the computer output in that same program
channel.

Appendix D: Crossfader Replacement

The crossfader is designed to give you many years
of use, but in the event of a problem (or many years of
use) we have made it very easy to replace.

Tools and qualications

To replace the crossfader, you will need a small
phillips screwdriver, nerves of steel, grit, determination,
and a steady hand. (This is not a good day to give up
coffee.)

Procedure

1. Turn off the d.4 Pro, and remove the power
cord, and any other cords or cables connected
to the d.4 Pro.

2. Gently place the d.4 Pro face upwards on a
flat, clean and dry surface, such as the kitchen
table.

3. Remove the crossfader knob, by gently pulling
it upwards. Keep it safe.

4. Take care to only remove the two outer screws
of the crossfader.

5. Gently lift up the crossfader assembly, just
enough to be able to pull the connector out of
the receptacle on the bottom of the assembly.

6. Insert the connector into the receptacle on the
new crossfader assembly. (It will only fit in one
way.)

7. Secure the crossfader assembly to the chassis
with the two screws you lost in step 4.

8. Check that the crossfader is working normally.

9. You might have to reset the tension, as shown
on page 17.

Appendix E: FireWire

System Requirements

FireWire stream to computer

The following table shows the outputs to your com-

puter from the FireWire interface inside the d.4 Pro:

These are the minimum requirements for your com-

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)

• G4 processor

• 256 MB RAM

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 record­ing of ALL the different inputs coming into the
mixer’s channels, as well as any audio coming
into either of the mic inputs, and keep all of it
separate for a later mixdown. In addition, with
the aux and main outputs also going to their
own tracks, you can have a completed main or

d.4 Pro 4-channel DJ Production Console

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 cross­fader.

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, post­EQ, 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.



d.4 Pro DJ Production Console

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 phono­level signals to line-level, and the routing through the

Owner’s Manual

switches takes it out via FireWire to your computer. You
can use the source switch to select FireWire or a CD to
play into this program channel without upsetting the
phono FireWire output (see dashed lines in figure 1).
This would be the way to play a timecode record. While
on the subject, I feel a paragraph or two coming on...

Timecode Vinyl/ CD

Timecode vinyl is a conventional vinyl record that

plays timecode information, as do timecode CDs.

The phono output from your turntable is converted to
line-level by the d.4 Pro phono stage (see figure 1). This
analog audio output is converted to a digital stream by
the FireWire interface and sent to your computer.

If you are playing a timecode CD on a CD deck, then
connect it to the line/phono inputs [4] and set the line/
phono switch [5] to line. (If it was connected to the CD
inputs [3], then the computer will not receive the direct
signals, but only those after the source selector, level
and EQ.)

Software provided by your timecode vinyl people takes
the digital stream and creates a virtual turntable on
your desktop. You can add any audio track to the virtual
turntable, and affect its output by scratching your physi­cal turntable to your heart’s content. The timing of your
audio track is replaced by the timecode of your turn­table. If the physical turntable slows down or reverses,
so does your audio track. Now you have control over any
audio source you care to play.

You do not want the timecode audio to actually play
in your system. In figure 1, out it goes to the computer
without a care in the world. With the source selector
set to FireWire, you can now bring in the affected audio
from your virtual turntable, and play it through the
same program channel and onto the main mix bus (see
dashed lines in figure 1).

Timecode tracks are carefully laid down by talented
timecode musicians. They like nothing better than to
get together for impromptu all-night timecode
jam sessions, and tell stories of the
good old days before 33 1/3.

Much-respected in this field are
“The Timecode Cowboys,” whose lat­est record “Like a Timecode Cowboy,”
is getting rave reviews.

FireWire stream from computer

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

From To

Computer output 1 Input to PGM 1 L

Computer output 2 Input to PGM 1 R

Computer output 3 Input to PGM 2 L

Computer output 4 Input to PGM 2 R

Computer output 5 Input to PGM 3 L

Computer output 6 Input to PGM 3 R

Computer output 7 Input to PGM 4 L

Computer output 8 Input to PGM 4 R

Each 2-channel stream from the computer enters the
mixer through the FireWire connector and is converted
to analog. Select FireWire as a program choice using the
desired channel’s source switch [30], the same way you
select a phono/line level, or CD player input.

Beware of a possible feedback loop if you are
feeding the d.4 Pro main mix back into an
input that is assigned to the main mix.

Owner’s Manual

7

MIDI notes

The d.4 Pro will show up on a Mac or PC as a 1 input,
0 output MIDI interface named “D.Pro Mixer.” On a PC,
the 0x1 MIDI interface shows up in all MIDI compatible
applications. On a Mac, the 0x1 interface will show up
in all compatible applications, and be visible in the
Audio MIDI setup utility.

The single MIDI input will present, to any MIDI com­patible application, the following MIDI messages:

• A controller message, tied to the crossfader,
with a value of 0 at hard left, 127 at hard right,
with in-between values equally spread out
across the crossfader’s travel. This allows you to
use the crossfader as a performance controller
with all sorts of audio software.

• A separate, unique MIDI note-on message for
each program fader that is assigned to the
crossfader. The note-on message will be gener­ated when the crossfader is moved even slightly
from the side to which the program channel is
assigned. This will allow you to trigger sound
effects or musical passages from audio software
that can respond to MIDI note-on messages.
Similarly, the note-off message is generated
when the crossfader reaches the end of its
travel at the side where it is assigned. Each pro­gram channel is assigned a note number that
accompanies the note-on and note-off messag­es. 0 is presented for channel 1, 1 for channel 2,
2 for channel 3, and 3 for channel 4.

d.4 Pro 4-channel DJ Production Console
