1. Introduction
Thank you for choosing the MIXVIBES U46MK2.
The U46MK2 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 Mix output. Two Phono inputs
make the unit a perfect portable solution for digital DJs compatible with all current major DJ
software applications.
The U46MK2’s flexible 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.
Six line level analog outputs allow you to connect the U46MK2 to various external devices or to
a 5.1 surround system. A separate Mix output and headphone output allow you to monitor
your inputs and outputs directly. The U46MK2 offers all these features in metal casing that can
travel with you anywhere.
Even if you are an experienced professional please take some time to read through this user
manual and familiarize yourself with the U46MK2’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 the U46MK2 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 external devices or to a 5.1
surround system.
5) Mix output: You can monitor all input sources and output sources through the Mix output.
Usually you can use Mix out to connect to powered monitor speakers.
6) Ground plug: When you use a turntable connect the ground lead from your turntable to
the ground plug to help preventing 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
most recent patches provided by your motherboard or chipset manufacturers.
Locate an available USB port on your computer. A sample USB port is pictured below. It is
typically located next to the PS/2 or serial ports on the back of your computer.
Plug the U46MK2’s USB cable (Series A plug type) into the USB port of your computer.
Turn on the U46MK2’s power button. After that you will see a power led switch on on the
U46MK2’s front panel. The U46MK2 gets the power from the computer via a USB cable. You
can also use an external 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 U46MK2 your computer will automatically detect the
U46MK2 as a USB Composite Device and will proceed with the installation.
1. To confirm the installation of the U46MK2 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 your setup requires all 6 outputs, you
must choose the 44.1 kHz sample rate.

1) Config – Mouse Wheel
Sets the speed of your mouse wheel for input/output levels adjustments.
2) Config – Latency
Sets the latency for your U46MK2. A typical value is 256 samples.
3) Config – Factory Default
Resets the settings to factory default.
4) Config – Always on Top
Allows you to keep the interface on top of other applications.
5) Config – SampleRate
Sets the sample rate (44100 Hz or 48000 Hz).
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 your setup requires all 6 outputs, you
must choose the 44.1 kHz sample rate.
6) Config – Buffer Number
Allows you to specify the number of buffers in order 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.
Example: In this case the outputs of the MME drivers are connected to the inputs of the ASIO
drivers of the U46MK2. Thus the sound played by the MME drivers can be recorded in ASIO
mode.

6. Application Setup
This chapter contains basic configuration example with the MixVibes CROSS LE 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 your setup requires all 6 outputs, 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 U46MK2 system as the main
sound device for Windows multimedia applications. Go to “My computer-> Control panel ->
Sounds and Audio Device Properties -> Audio”. Select the U46MK2 driver as your playback and
recording device.
Important note
You must not use the same ASIO driver at the same time otherwise a sample rate
error will occur. For example, if you set the ‘U46MK2’ 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 U46MK2. Run the Config/Latency menu to set the audio latency. 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 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 of 512 samples provides a
basic level of compatibility with different systems.

6.3. MixVibes CROSS LE
The U46MK2 includes the full version of MixVibes CROSS LE. Once CROSS LE is installed and
launched open the “File -> Preferences” menu and select the Audio panel as shown below:
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 your setup requires all 6 outputs,
you must choose the 44.1 kHz sample rate.
Important note
The U46MK2 is fully compatible with MixVibes HOME, CROSS LE, DVS and DVS PRO.
