1. Introduction
Thank you for choosing the MIXVIBES U46MKII.
The U46MKII is an ideal mobile recording interface for both laptops and desktop computers. It
offers a 4-in 6-out multi-channel audio interface with a separate Mi output. 2 Phono inputs
make the unit a perfect portable solution for digital DJs, compatible with all current major DJ
software applications.
The U46MKII’s fle ible 4 inputs enable you to record from a variety of sources. There are 2
Phono inputs, 2 stereo Line inputs, and a MIC input with +48V phantom power and Hi-Z
(E.Guitar) input.
6 line level analog outputs allow you to connect the U46MkII to various e ternal devices or to
a 5.1 DVD surround connection. A separate Mi output and headphone output allow you to
monitor your inputs and outputs directly. The U46MKII offers all these features in metal casing
that can travel with you anywhere.
Even if you are an e perienced professional, please take some time to read through this user
manual and familiarize yourself with the U46MKII’s features and operation. You may also want

2.2. Rear Panel
(1) External Power supply connector:
If you use a microphone that requires phantom power, especially with a laptop
computer, it’s strongly recommended to use a DC +9V/500mA adapter (not
included). When you turn on U46MKII or when you turn on/off phantom power, the
current peak level might go over 500mA.
(2) USB connector: Connects the USB cable to the computer.
(3) Input 1~4: The turntable inputs and line level inputs share the same connectors. The
RCA turntable inputs feed an RIAA equalized preamp designed to accept moving magnet type
phono cartridges.
(4) Output 1~6: You can use these outputs to connect to various e ternal devices or to a 5.1
DVD surround connection.
(5) Mix output: You can monitor all input sources and output sources through the Mi output.
Usually, you can use Mi out to connect to powered monitor speakers.
(6) Ground lug: When you use a turn-table, Connect the ground lead from your turntable to
the ground lug to help prevent hum.

3. Hardware Installation
3.1. Minimum system requirements
Intel Pentium III 600MHz CPU or equivalent AMD CPU
256MB of RAM
Direct X 8.1 or higher
Microsoft Windows® XP or Windows® Vista, Mac OSX.
One available USB port
3.2. Installation
Before proceeding to driver installation, please locate your original Windows CD, as you may
need it during installation. If you have a motherboard with a new chipset, please install the
recent patches provided by your motherboard or chipset manufacturers.
Find the USB port on your computer. A sample USB port is pictured below. It is typically
located ne t to the PS/2 or serial ports on the back of your computer.
Plug the U46MKII’s USB cable (Series A plug type) into the USB port of your computer.
Turn on the U46MKII’s power button. After that, you will see a power led switch on, on the
U46MKII’s front panel. The U46MKII gets the power from the computer via a USB cable. You
can also use an e ternal Power supply if you have one.
Important Note
Some of your computer USB ports may not recognize the U46 mk2. In this case,
simply try to connect the device to another USB port

4. Driver Installation
After connecting and powering the U46MKII, your computer will automatically detect the
U46MKII as a USB Composite Device and will proceed with the installation.
1. To confirm the installation of the U46MKII, go to ‘Start-> Settings-> Control Panel ->
System -> Device Manager’. Confirm that two (2) instances of “USB Audio Device” are listed
under ‘Sound, video and game controllers’ and that one (1) “USB Composite Device” is listed
under ‘Universal Serial Bus controllers’.
2. Check your system.
Go to: Control Panel > Sounds and Audio Devices > Audio
Please check that your audio devices are installed properly.
Important note
Due to the limitations of the USB 1.1 driver, audio output at 48 kHz sample rate is
limited to 4 channels. If you need better audio quality and don’t need all 6 outputs,
you can choose the 48 kHz sample rate. If you need all 6 outputs for your work, you
must choose the 44.1 kHz sample rate.

Important note
Due to the limitations of the USB 1.1 driver, audio output at 48 kHz sample rate is
limited to 4 channels. If you need better audio quality and don’t need all 6 outputs,
you can choose the 48 kHz sample rate. If you need all 6 outputs for your work, you
must choose the 44.1 kHz sample rate.
(6) Config – Buffer Number
Allows you to modify the number of buffers to diminish or improve latency and system
stability.

Direct WIRE allows you to connect the ins and outs of your various audio devices and audio
drivers.
E ample: In this case, the outputs of the MME drivers are connected to the inputs of the ASIO
drivers of the U46MKII. Thus the sound played by the MME drivers can be recorded in ASIO
mode.

6. Application Setup
This chapter contains basic configuration e ample with the Mi Vibes 3DEX DJ Software. Please
also refer to the manual of the audio software you use for detailed information.
Important note
Due to the limitations of the USB 1.1 driver, audio output at 48 kHz sample rate is
limited to 4 channels. If you need better audio quality and don’t need all 6 outputs,
you can choose the 48 kHz sample rate. If you need all 6 outputs for your work, you
must choose the 44.1 kHz sample rate.
6.1. Windows® Multimedia setup
The Windows Multimedia setup is required if you want to use your U46MKII system as the
main sound device for Windows multimedia applications. Go to My computer-> Control panel -
> Sounds and Audio Device Properties -> Audio. Select the U46MKII driver as your playback
and recording device.
Important note
You must not use same ASIO driver at the same time otherwise a sample rate error
will occur. For example, if you set the ‘U46MKII’ as your windows multimedia
playback device, you should not choose a different ASIO driver for your audio
application. Otherwise the setup might fail when Windows sound scheme is played.

6.2. Latency setting on ASIO applications
Clicking the ASIO Control Panel button (or config) of ASIO applications will open the ASIO
latency setting of the U46MKII. Run the Config/Latency menu to set the latency time. Here you
can choose between different buffer sizes. Typically a lower latency is good when working with
software synthesizers or when you process audio signals from the audio inputs in real-time
with your audio software. A smaller latency value will however also cause more system load.
For a typical faster Pentium 4 system, 128 ~ 256 are good values. Buffer sizes 1024 and 2048
are normally used only in special circumstances. The factory default is 512 to provide a basic
level of compatibility to different systems.

6.3. MixVibes 3DEX
The U46MKII includes the full version of Mi Vibes 3DEX. Once 3DEX is launched, run the
‘File/Options’ menu then choose the ASIO mode as described hereafter:
Again, due to the limitations of the USB 1.1 driver, audio output at 48 kHz sample
rate is limited to 4 channels. If you need better audio quality and don’t need all 6
outputs, you can choose a 48 kHz sample rate. If you need all 6 outputs for your
work, you must choose a 44.1 kHz sample rate.
Important note
The U46MKII is compatible with MixVibes HOME, 3DEX, DVS and DVS PRO. The setup
is exactly the same than above.
