Computer Control –How the MIXDECK connects to and controls software
The MIXDECK’s USB connection connects the built-in audio interface, and two playback decks to your Mac or PC.
Important things to know:
The Audio interface in the MIXDECK requires drivers. Without the latest drivers installed, the MIXDECK can’t
connect to the computer. Download the latest drivers at www.numark.com/mixdeck.
About the Mixer section: while the platters and buttons on the left and right playback decks send MIDI messages
to the computer, the center section is an analog mixer, and does not send any messages to the computer.
This means the knobs and sliders on the mixer will not move the knobs and sliders on the screen in your
software. That’s OK, the software is expecting this, and will send separated un-mixed audio to CH1 and CH2 on
the mixer. You’ll be able to scratch, cue, and control everything you need.
The MIXDECK is a lot like having four pieces of gear in one…
1. A 4 channel (2 stereo channels) sound card like the Numark DJiO
2. An individual MIDI capable, touch-sensitive, scratching CD decks like the Numark NDX900.
3. A second individual MIDI capable, touch-sensitive, scratching CD decks like the Numark NDX900.
4. An analog mixer like the Numark iM1.
...except without all the extra connection cables or power supplies. Plus, it fits better in a case!
Even through just one USB cable connects the MIXDECK to the computer, each deck, and the sound card
are seen by the computer separately.
For tips on setting up your MIXDECK to control your DJ software, see the guide on p.3.

DJ Software Setup Walkthroughs
If you are having difficulty setting up the MIXDECK to control your DJ software, don’t worry, there’s nothing wrong. This
virtually never indicates a hardware problem with the MIXDECK, and can be resolved on 5-10 minutes.
Note: On Windows PCs, Logitech Webcam drivers interfere with virtually all brands and models of USB Audio or MIDI
interfaces (like the MIXDECK). If you have connected a Logitech Webcam to your Windows PC, now or any time in the past,
contact our Technical Support team. We can assist in resolving the conflict, quickly getting you back on track.
Most often, you just need to perform the needed software and hardware setup. Software setup walkthroughs are included
below:

Adjusting Latency Settings to fine tune computer performance
1. The MIXDECK Driver installation includes a control panel which allows the latency to be adjusted.
The control panel can be found under Start > Programs > Numark > MixDeck Panel.
2. In the window that opens, select a new setting from the Audio Latency Settings menu. Higher settings, such as
1024 will provide more stability. Lower settings will provide less delay between button or slider activity on the
hardware, and results in the software.
3. Click Exit to confirm your selection.
Setting which deck is 1 and which deck is 2 in Virtual DJ LE
Even through just one USB cable connects the MIXDECK to the computer, each deck, and the sound card are
seen by the computer separately. Because of this, it is not always possible to force the computer to recognize the
left deck first (as Deck 1), and the right deck second (as Deck 2).
In Virtual DJ LE, it is easy to swap which deck inside the software sends its audio to CH1 on the MIXDECK mixer,
and which deck in the software sends its audio to CH2 on the MIXDECK mixer.
1. Launch Virtual DJ LE
2. Click the Config button in the upper-right of the screen.
3. At the top of the window that opens, select the Sound Setup tab.
4. Choose which deck configuration you would like from the pull-down menu. If your software is sending its audio to
the opposite channels on the MIXDECK mixer, choose a different option from the pull-down menu to correct.
5. Click Apply, then click OK to confirm your changes.

How to disable the PWR ON PLAY, and PWR ON DEMO features
The MIXDECK ships with two features enabled that are intended to help stores and dealers easily demonstrate the
product on their showroom floors: PWR ON DEMO, and PWR ON PLAY.
PWR ON DEMO –shows off the illuminated platter, using the RED LEDs to present a light show even if nothing is
playing on the MIXDECK.
PWR ON PLAY –when this feature is enabled, if you leave a disk in the deck, it will automatically begin to play
the next time you power-on your MIXDECK.
To disable either of these features perform the following steps on both the left and right decks on the MIXDECK.
1. Press and hold the PROG button located the lower-left of the screen.
2. While holding down the PROG button, turn the PARAMETER knob until the feature you’d like to change is
displayed:
Or
3. While continuing to hold down the PROG button, press the PARAMETER knob (like a button). The text on the
screen will flash.
4. Now, (while continuing to hold down the PROG button) rotate the PARAMETER button to change the option from
ON to OFF. Press the PARAMETER knob (like a button) once more to confirm your selection.
The text on the screen will stop flashing, and the display should read the following:
Or
5. Release the PROG button.

CD - Read Difficulty
If a player on your MIXDECK is not reading any CD at all, including store-bought disks, contact our support team for
assistance.
If the difficulty occurs only with burned disks, or only with some burned disks, this generally indicates that the disks
themselves are the most significant factor.
The suggestions included below might be helpful in this case:
The importance of using high quality media and slow burn speeds
Your clients depend on you, you depend on your gear, your gear depends on the media you feed it. We
recommend that DJ’s be as picky as possible when choosing the brand of CD-R, and the burning speed they
use. If store-bought disks are playing fine, but burned disks are not, then it means there are significant enough
errors on the burned disks that the CD is in danger of not being fully playable in all machines. If one player (that
plays store-bought disks fine) has difficulty even one time, this means that the disk has significant errors on it.
Consider re-burning it on higher quality media with a slower burn speed.
By using high quality media, and slow (i.e. not 52x) burn speeds, you can create disks with low errors. The
slower the burn speed, the fewer the errors. This way, the buffer in the CD player can be used to ensure that
when your disks get beat up down the line, they can still play. If the buffer is used up dealing with the errors
induced by poor media or fast burn speeds, then the lifespan of that disk will be extremely short (regardless of the
player you use).
We often use a car tire analogy: Treads on new tires aren’t as thick as they are because tires require that
thickness to be safe. The treads on new tires are thick because we know the tire will wear over time, and we
want them to last as long as possible. Using poor media or fast burn speeds is like choosing to drive on bald
tires. You can do it (my dad sure did), and you may find people who will say they’ve driven thousands of miles on
these tires with no problem. While you may be fine for a while, and could make a habit or a career out of it, the
danger is always there. When people are depending on you, you want as much buffer between you and disaster
as possible.
CD-RW
CD-RW disks are not supported. When burning your own music, purchase disks that are labeled CD-R only.
Enhanced CD (also known as CD Extra or CD Plus)
Enhanced CD is a format that included extra contact such as videos, photos, computer applications etc. This
format is not supported by Numark CD players.
Variable bitrate (VBR) MP3 files
Many Numark CD players (including the MIXDECK) support MP3 CD-R disks. For the best playability and fastest
read times, we recommend using constant bitrate MP3 files. variable bitrate files are more difficult to read and
are not recommended. Make sure your MP3 encoding software is not set to use Variable bitrate (VBR).

CD-R Audio and CDR-Music
Disks labeled “CD-R Audio” or “CD-R Music” are different than “CD-R”, and are not recommended.
“CD-R Audio” or “CD-R Music” disks are required by certain types of stand-alone consumer audio CD-burners
which were commonly sold in the consumer channel, usually as part of home theater systems. Products that
require these disks are relatively rare in the marketplace today. Computers do not require these types of disks,
and using them can lead to read difficulties.
Sony CDRM80 CD-R Music (CRM-80/30SP)
When burning disks for use in any professional DJ CD player, it is recommended to use disks simply labeled “CD-
R” for any computer-based burning, or with any burner that does not specifically require disks labeled “CD-R
Audio” or “CD-R Music”. Stand-alone burners which do require “CD-R Audio” or “CD-R Music” disks will create
disks which may have difficulty reading in some players.
In addition to the above, we always recommend using high quality media and slow burning speeds to minimize
error rates (which improves readability and longevity).

Software Authorization Assistance
We have a process in place where customers can be provided replacement authorization codes and/or download links if
they have lost their disk, or encounter difficulty authorizing the included software.
When circumstances allow, replacement authorization codes are issued to customers free of charge. We do require a
basic set of information to be supplied in any situation where a replacement code is requested by an individual. This
required information and further contact details can be found on the website below.
