PART 1. Using USB Mixer with a Computer 
Universal Serial Bus Mixers 
The USB mixer is equipped with either one or two USB ports that allow you to play and record audio directly from your 
computer! Just hook up a USB cable, and the software drivers will automatically install. You can then play MP3, WMA, 
WAV or any other audio format that your computer is capable of, through your mixer. Or, you can record your 
performance from your mixer to your computer’s hard drive and burn it to a CD later. Each USB port can record and 
play at the same time. 
The USB interface on your mixer works with your computer just like a standard USB sound card. Therefore, you can 
use almost any audio software on the market to play and record from your computer to your mixer. No lengthy 
installation process or custom drivers are necessary. Simply plug it in and go! 
Recommended system requirements: 
- Current processor (as of 1 GHz) 
- 512 MB RAM 
- PC running Windows 98SE, ME, 2000, XP, or XP Professional, with at least one USB port. Or, a Mac running OS 9.1 
or X with at least one USB port. The USB port can be USB 1.1 or greater. 
PC Connection 
1.  Boot your computer (Mac/PC) and wait until everything has loaded completely, then turn on your USB mixer. 
2.  Connect your mixer to your computer using a USB cable. 
3.  Windows will immediately recognize the mixer as a “USB Audio Device” or “USB Audio CODEC” and automatically 
install the drivers if necessary. 
4.  The first time you do this, your mixer will de automatically assigned as the Default (or “preferred”) Device for sound 
playback on your computer .All of your computer’s sounds will be sent to the mixer via the USB cable. 
5.  You can now open any media players or recorders on your computer and they should play and record through your 
mixer. This includes Windows Media player and almost any other audio player that works on your PC. To prevent 
your computers system sounds (bleeps and bells) from going to your mixer, you may want to disable your 
computer’s sounds or redirect them to your computer’s speakers (see below for how to do this). 
(Note, for Windows 98SE, you may need to insert your need to insert your original Windows 98SE CD ROM during 
the installation process.) 
Changing Your PC’s Default (or preferred Sound Playback Device) 
If you are not hearing sound from your mixer, you may need to tell your computer to send audio to your mixer instead of 
another sound card or the computer’s onboard speakers. Here’s how to do that: 
1. Click 
StartSettings, and Control Panel and double-click the Multimedia icon (Windows 98); click StartSettings
and Control Panel and double-click Sounds And Multimedia (Windows Me/2000); or click Start and Control 
Panel
, select the Sound, Speech, And Audio Devices link, and then click Sound And Audio Devices (Windows 
XP). 
2. 
In the Sounds and Multimedia Properties dialog box, click the Audio tab.
 
3.  Grab the pull-down selections under “Sound playback”. The 
mixer should appear as a “USB Audio Device” or “USB Audio 
CODEC”.  
(If you already have another USB Audio Device attached to you 
computer, then the mixer will appear as “USB Audio Device 
(2)or USB Audio CODEC (2)”.) Select the desired playback 
device. 
4.  Similarly, under the “Sound Recording” pull-down, select the 
desired recording device. 
5.  Make sure the “Use Only Preferred Devices” box is not 
checked. 
6. 
Click
 Apply or OK. 
7.  While using your computer with your mixer, it is a good idea to 
keep the “Sounds and Multimedia” box open in the background, 
since you will need to access this often. 
Note, some programs, like Windows Sound Recorder, give you 
quick access to the “Sounds and Multimedia” box. In Windows 
Sound Recorder, click under the “Edit” menu item and select “Audio 
Properties”. The box will pop up and allow you to change the 
preferred Audio Devices. 
Playing and Recording 
Once you have performed the above steps, you can immediately use your favorite playback or recording programs 
with your mixer! If you don’t have any special DJ playback or recording programs, you can use Windows Media player 
and Sound Recorder, which come with Windows. Normally, Windows Media player starts when you double-click on an 
MP3 or other audio file.
