7. USB
Connects the 0202 USB 2.0 to your computer via the supplied USB cable. The 
USB connection provides two-way communication when connected to the 
computer. 
NOTE to PC Users:
When using a USB 1.1 port, 
performance is limited to
16-bit and 44.1/48 kHz 
recording and playback.The 0202 USB 2.0 receives its power from the USB. Always connect to the USB 
jack on the computer itself and NOT to a low-power USB connection that 
may be present on your computer keyboard or other USB peripheral.
8. Main Outputs
The balanced outputs are normally connected to your monitoring system. The 
signal is duplicated on a stereo 1/8¨ jack for easy connection to desktop 
stereo speakers. The outputs have been designed using a special noise-
cancelling circuit which reduces problems relating to ground loops.
 The main 
output volume can be controlled using the System Volume Control on your 
Mac or PC.
9. R - Hi Z / Line Input
This 1/4¨ input can be used as a Hi-Z instrument input (guitar/bass, etc.) or a 
line level input. The input is balanced, but accepts either balanced or unbal-
anced signals.
10. L - 1/8¨ Mic Input
Connect microphones with 1/8¨ plugs to this jack.
11. L - Hi-Z / Line / Mic Input
Use the XLR connector for microphones or balanced line level signals. Use the 
1/4¨ in the center of the XLR jack as a Hi-Z input for guitar/bass, or as a line 
level input. The input is balanced, but accepts either balanced or unbalanced 
signals.
Ground Lift Switches
There are “ground lift” switches for both analog inputs located on the bottom 
of the unit. These switches can be used to safely stop the hum if a ground loop 
occurs in your setup. See page 18

							Direct Monitoring
16E-MU Systems
DIRECT MONITORING
Direct monitoring allows you to monitor inputs without having any software 
open.  It can also be used as an alternative to software monitoring if you desire the 
lowest latency monitoring possible.
When using a computer for digital recording, an audible time delay occurs while 
the audio signal is being input to the computer, processed by the software and then 
returned to the output for monitoring. This time delay is called Latency. 
Latency becomes a problem when you have to use high buffer settings to conserve 
CPU resources. Because the 0202 USB 2.0 has hardware direct monitoring, you can 
enjoy zero latency regardless of your buffer setting. 
NOTE
Direct monitoring is not 
available at 176.4 or 
192 kHz.The Direct Monitor feature connects the input signals to the output when recording 
so that you can hear your performance without delay. The Direct Monitor level 
control lets you adjust the volume of the input signal in relation to the recorded 
tracks.
Direct monitoring is controlled manually from the Direct Monitor switch on the 
0202 USB 2.0. It’s not necessary to turn it on in your recording application
Direct Monitoring vs. Software Monitoring 
Direct monitoring is lower latency and can also be used without software running 
(or even without a computer!).
Software monitoring has the advantage of allowing audio effects or EQ added in 
the host software to be heard on the output. Its roundtrip latency depends on what 
latency is chosen in the ASIO configuration. If you choose to software monitor, 
make sure to disable direct monitoring. If both are enabled, you will experience a 
‘comb filter’ or doubling effect.

Direct Monitoring Latency (delay)
Direct Monitoring allows you to listen to the direct sound of your instrument during 
recording, without the delay incurred by going to the computer and back.

AUDIO RECORDING SOFTWARE
Now that you’ve installed the 0202 USB 2.0, you probably want to start using it! 
The 0202 USB 2.0 is only one half of the equation—the hardware interface that 
translates audio signals into the digital language of your computer. The second half 
of the equation is the software recording application, which records and allows 
you to edit the audio on your computer.
Acoustica Mixcraft LE 4
™
We have included Acoustica Mixcraft LE 4 for PC users. Acoustica Mixcraft LE 4 is 
a full-featured multitrack recording application with effects, virtual instruments, 
VST
™ and DirectX™ support and much more.
Tutorials and Videos: http://www.acoustica.com/mixcraft/support.htm
Macintosh Users
Unfortunately we were not able to include a Macintosh recording application with 
the 0202 USB 2.0, however you can use Garage Band, a very cool music appli-
cation that probably came bundled with your Mac. This application works well 
with the 0202 USB 2.0 and will get you started with audio recording.
NEED MORE HELP?
If you need additional help, please see: 
•Windows: Program Files\Creative Professional\E-MU 0202 
USB\Documents\3rdParty.htm.
•OS X: Applications Drive\Library\Documentation\E-MU 0202 USB 
3rdParty.htm
Before you Begin...
• You should have already installed the E-MU software on your computer
WARNING!
Windows Users - After 
checking your audio, be 
sure to quit Windows Media 
Player.• You should hear the computer sounds coming out of the E-MU 0202 USB 2.0 
and your speakers when you play a CD or an MP3 using Windows Media 
Player or iTunes. If not, make sure your E-MU 0202 USB 2.0 is properly 
connected according to the diagram on page 12
.
• A source of audio should be connected to the inputs (a microphone, musical 
instrument, or CD/MP3 player). 
						

							Troubleshooting
18E-MU Systems
TR O U B L E S H O O T I N G
Can’t hear Windows Media Player in Windows
If you have, or ever have had, another audio device installed in your PC, you may 
have to set the E-MU 0202 USB 2.0 as the “Default Audio Device”.
1. Open the Control Panel, then select Sounds and Audio Devices.
2. Click the Audio tab and select the E-MU 0202 USB 2.0 as the Default device 
under Sound Playback.
3. Click the Volume button under Sound Playback and turn up Wa ve  vo lu m e.
You cannot record or monitor ASIO and WAVE at the same time. The first audio 
application you open controls the E-MU 0202 USB 2.0.
Lost Communication
Should you lose communication between your E-MU 0202 and an audio appli-
cation (Ableton Live, Cubase, Sonar, etc.), the E-MU 0202 USB 2.0 drivers may 
need to be re-selected in your application.
1. Go to your applications I/O settings, de-select the E-MU 0202 USB 2.0 for 
both input and output.
2. Apply these changes and exit the dialog.
3. Re-enter the applications preference settings and re-select the E-MU 0202 USB 
2.0 drivers. If this doesn’t work, the application may need to be restarted.
Ground Loops
In digital audio devices and computers, audio ground loops may appear as pitched 
tones, digital hash in the background, as well as the familiar 60 cycle hum. 
Ground loops are caused by a difference in ground potential between two pieces of 
equipment. Computer audio devices are particularly susceptible to ground loops 
because most computers were not designed with high quality audio in mind.
The E-MU 0202 USB 2.0 contains built-in “ground lift” switches for both analog 
inputs in order to safely break the loop if a ground loop occurs in your setup.
The ground-lift switches are located on the bottom of the unit, close to the rear 
panel. The input ground is lifted when the A or B slide switch is closest to the GND 
LIFT label.
Pops & Crackles
Pops and crackling noises in the audio are most often caused by having the ASIO 
Buffer Size set too low. Adding audio tracks and VST plug-ins increases the load on 
your computer’s CPU. If your computer cannot keep up with all the tasks you are 
asking it to perform, pops and crackles may occur. In effect, increasing the ASIO 
buffer gives your computer “more time” to complete its assigned tasks. The 
hardware Direct Monitor feature of the 0202 USB 2.0 allows you to increase the 
ASIO Buffer setting without the associated latency problems during recording and 
overdubbing.
USB hubs can create problems with digital audio and should be avoided whenever 
possible.

Simultaneous WDM/ASIO Playback (PC only)
The 0202 USB 2.0 only supports playing back one stream format at a time on the 
PC. Each of the three mentioned stream types has an associated priority. If a higher 
priority stream type is opened while a lower priority stream is already playing, the 
lower priority stream will stop playing. The stream priorities, from highest to 
lowest, are ASIO, WDM.
USB 2.0 vs. USB 1.1 Operation (PC only)
The 0202 can operate in USB 2.0 or USB 1.1 mode on the PC. The 96 kHz and 192 
kHz sample rates are only available while operating in USB 2.0. The included 
E-MU USB Audio Control panel software includes an indicator to let you know 
which mode the device is running in.
0202 USB comes up in USB 1.1 mode (PC only)
Always turn the 0202 USB power off before connecting or disconnecting the USB 
cable. Hot-plugging the unit with the power on can cause the 0202 to power-up in 
USB 1.1 mode. If you see the Windows message, “This device could perform 
faster…”, simply turn power off, wait a few seconds, then turn power on again.
