0202 USB 2.0 Owner’s Manual 15
Direct Monitoring
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
Latency (delay)
USB
Software Monitoring
Direct Monitoring
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.
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.

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.

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 application 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
• 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).

WARNING!
Windows Users - After
checking your audio, be
sure to quit Windows Media
Player.

Troubleshooting
TROUBL ESHOO TING
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 Wave volume.
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 application (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 application's 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 application's 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.
Input Grounded
R-GND LIFT
L-GND LIFT
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.
