4.3 Conguration
This chapter explains how to use the GUITAR RIG MOBILE I/O audio interface with Windows
XP / Windows Vista and particularly with the included GUITAR RIG 4. It is assumed that you
have already activated GUITAR RIG 4 using the Service Center – please refer to the Setup
Guide for help on this process.
4.3.1 Conguring GUITAR RIG 4
We will now set up GUITAR RIG 4 to use the GUITAR RIG MOBILE I/O audio interface. Start
the software before you proceed.
1.
When the software is started for the rst time, you will be prompted with the Audio Setup
window automatically, where you need to make the following settings. To access these
settings later on, select File > Audio and MIDI Settings from the program menu.
2. From the “Audio” tab, choose ASIO as the driver interface.
3. Select GUITAR RIG MOBILE I/O from the “Device” dropdown menu.
GUITAR RIG MOBILE – 19
If GUITAR RIG MOBILE I/O doesn’t appear in the list, something went wrong. Restart the
installation as explained in section 4.1.
You can access the Driver Control Panel by clicking on “ASIO Cong”. In the Driver Control
Panel, two status elds on the bottom show whether the GUITAR RIG MOBILE I/O hardware
is connected and ready to use.
The audio interface allows to be congured by the following parameters:
• Presets: Several presets for common types of usage are included, from minimal latency
suitable for fast systems with strong CPU power, to higher latencies suitable for slower systems. If you are experienced in setting up audio drivers and want to create your own custom
settings, select User Dened Settings.
•
USB Buffersize and Audio Buffersize: These parameters are grayed out, unless you have
selected User Dened Settings from the Presets Menu. Together, they dene the system’s
latency, i.e. the time that passes from the moment an audio signal is sent into the GUITAR
RIG MOBILE I/O hardware until the moment you hear it in your headphones or your speak-
GUITAR RIG MOBILE – 20
ers. The value for Audio Buffersize must always be at least twice as large as the Usb
Buffersize value. Note that the Usb Buffersize parameter has a direct impact on the CPU
usage of the system. The resulting CPU usage differs between computers, so it could make
sense to experiment with different settings.
•
Sample Rate: Choose a sample rate that is compatible with your music application and
suited to your computing power. Per default, the sample rate is set to 44100 Hz (CD-Quality).
Higher sample rates may improve sound quality, but cause a higher CPU load as well.
It is recommended that you try the latency presets rst and then continue with the subsequent steps of the installation. Once you are nished, you should revisit the Audio and MIDI
Settings to gure out the best latency setting for your system. If audio dropouts occur with
the preset minimal latency, you can try the low latency or standard latency settings instead.
Higher latency values will reduce the probability of audio dropouts.
4.3.2 Using GUITAR RIG MOBILE I/O as your Default Audio Interface
If you want to use the GUITAR RIG MOBILE I/O for playback of all audio applications on your
computer (not only for music software), you have to set it as your default audio interface.

6. Click Ok to close the dialog.
GUITAR RIG MOBILE – 22
4.4 Audio Connections and Levels
In the following chapters you will learn how to connect your guitar and your monitoring system to the GUITAR RIG MOBILE I/O and how to set the right amplication levels both on the
hardware and on the software side of your setup.
Please start GUITAR RIG 4 before you proceed.
4.4.1 Connecting the Input and Adjusting the Input Level
1. Turn down the volume on your monitoring system to prevent hearing damages.
2.
Plug the cable connected to your guitar or bass into the input jack socket of the interface.
Mind that, for an instrument that generates a stereo signal, you might need a split (insert
cable / y-cable, not included) to route both channels to the stereo input jack.
In order to achieve the best sound quality by providing the interface with a sufciently powerful signal, you need to carefully adjust the input level of the GUITAR RIG MOBILE I/O.
GUITAR RIG MOBILE – 23
The Input Level LED helps you identify the level of the incoming signal:
LED Status Meaning
LED is off No incoming signal
LED ashing green Incoming signal
LED ashing red Incoming signal is too loud
Before adjusting the input sensitivity, turn up the volume knob on your guitar. Strum some
chords at the volume level you are typically playing at and monitor the Input Level LED:
1. Turn up the input level knob just until the LED starts turning red when you play.
2. At that point, slightly turn the knob down until the LED no longer turns red, even when
you are playing really powerful chords.
Now the input sensitivity is set to its optimum level, enabling the GUITAR RIG MOBILE I/O
to provide the highest dynamic range without clipping.
4.4.2 The Input Level of GUITAR RIG 4
It is assumed that your guitar is connected to the GUITAR RIG MOBILE I/O and its input level
is properly adjusted (see section 4.4.1). Now you need to make sure that the input signal is
processed at the right level by the software.
Please take a look at the header of the GUITAR RIG 4 window: It consists of the input module
with channel selectors, a basic noise gate, the output module with a limiter and information
about the processing power consumed.
GUITAR RIG MOBILE – 24
%
For a detailed description and explanation of the Noise Reduction circuit, please refer to the
GUITAR RIG 4 Application Reference included on the product CD.
Note that the Input Meter shows an amplitude when you are playing. It also features an integrated volume fader that controls the input level of the software. Please adjust it to achieve
the highest possible level for your signal without clipping. This is indicated by the Level Meter
getting close to the red zone without actually hitting it.
Now we will set up the Input component to route your guitar signal to both channels. Because
almost all guitars are mono, GUITAR RIG 4 will receive a mono signal which is transmitted
on the left channel. Per default, GUITAR RIG 4 is set to process both input channels (L + R
are activated), so the right input channel remains mute. To change this, click the “R” button
on the left hand side of the Input Meter to deactivate the right input channel. This will route
the mono signal to both input channels.
4.4.3 Connecting the Output
GUITAR RIG MOBILE I/O provides a stereo output which works both for amplication systems
and for headphones. Keep in mind that using a mono cable (like a guitar cable) will result in
the transmission of one channel only – you might need a split (insert cable / y-cable) to route
both channels to the inputs of your amplication system.
Use a stereo cable to connect the GUITAR RIG MOBILE I/O to devices that feature a stereo
input jack.
GUITAR RIG MOBILE – 25
Before turning on your power amplication system or putting on your headphones, make sure
the output level of the audio interface is turned down.
•
If you are using an amplication system, connect the output jack to its input and turn it on.
• If you are using headphones, connect them to the output jack and put them on.
•
Go to the Preset Browser and select a preset by clicking on it. Start playing and carefully
turn up the output volume of the GUITAR RIG MOBILE I/O to the desired level. You’re all set
now and ready to rock!
%
If your instrument uses only one channel, set the other channel’s Gain Knob to zero.

5.3.1 Conguring GUITAR RIG 4
We will now set up GUITAR RIG 4 to use the GUITAR RIG MOBILE I/O audio interface. Start
the software before you proceed.
1.
Start GUITAR RIG 4. When the software is started for the rst time, you will be prompted
with the Audio Setup window automatically, where you need to make the following settings. If you want to access these settings later, select GUITAR RIG 4 > Preferences from

GUITAR RIG MOBILE – 30
The audio interface allows to be congured by the following parameters:
•
Sample Rate: Choose a sample rate that is compatible with your music application and
suited to your computing power. Per default, the sample rate is set to 44100 Hz (CD-Quality).
Higher sample rates may improve sound quality, but will cause a higher CPU load as well.
•
Latency: Use the Latency slider to set the buffer size of the audio interface, measured in
samples. The buffer size has two effects: The higher it is set, the lower is the probability of
dropouts during real-time audio processing. On the other hand, the size of the buffer directly affects the overall latency of your system. The time between the moment you hit a
note and the moment you hear the processed sound will be longer if the buffer size is increased.
It is recommended that you start with the default buffer size and continue with the subsequent steps of the installation. Once you are nished, you should load a clean preset and
revisit the Audio and MIDI Settings to gure out the best latency setting for your system. This
is done by gradually reducing the buffer size: Drag the latency slider to the left while playing
something. Once you begin to hear crackles or dropouts, carefully drag the latency slider to
the right until you reach the point where no crackles or dropouts occur.
5.3.2 Using GUITAR RIG MOBILE I/O as your Default Audio Interface
If you want to use the GUITAR RIG MOBILE I/O for all audio playback (not only for music software), you have to set it as your default audio interface. For Mac OS X, this works as follows:

GUITAR RIG MOBILE – 34
on the left hand side of the Input Meter to deactivate the right input channel. This will route
the mono signal to both input channels.
5.4.3 Connecting the Output
GUITAR RIG MOBILE I/O provides a stereo output which works both for amplication systems
and for headphones. Keep in mind that using a mono cable (like a guitar cable) will result in
the transmission of one channel only – you might need a split (insert cable / y-cable) to route
both channels to the inputs of your amplication system.
Use a stereo cable to connect the GUITAR RIG MOBILE I/O to devices that feature a stereo
input jack.
Before turning on your power amplication system or putting on your headphones, make sure
that the output level of the audio interface is turned down.
GUITAR RIG MOBILE – 35
•
If you are using an amplication system, connect the output jack to its input and turn it on.
• If you are using headphones, connect them to the output jack and put them on.
•
Go to the Preset Browser and select a preset by clicking on it. Start playing and carefully
turn up the output volume of the GUITAR RIG MOBILE I/O to the desired level. You’re all set
now and ready to rock!

6.1 Audio Issues
This section provides help with the most common audio issues you may encounter.
6.1.1 No Sound or Low Volume
There are several possible reasons for a silent or low audio output:
• Disconnected or broken cables. Please check all connections and cables.
•
Incorrect soundcard or audio input selected. Please check the Audio and MIDI Settings in
the GUITAR RIG 4 menu if the GUITAR RIG MOBILE I/O driver is selected.
•
Wrong channel selected in the Input module of GUITAR RIG 4. Switch to the other channel
by choosing “L” in the INPUT Module.
• The GUITAR RIG MOBILE I/O’s input gain is set too low. Turn up the Input Level.
• Your instrument’s volume is turned down. Gradually turn up the volume knob.
6.1.2 Distorted Signal
If the audio signal sounds distorted, and no distortion is being added by the GUITAR RIG 4
software, then this is most likely caused by the GUITAR RIG MOBILE I/O’s gain being set
too high. Reduce the Input Level at the Interface to prevent the preamp from clipping. If
your instrument delivers such a high signal that the preamp is always overdriven, you should
reduce its volume. Usually, this only happens if the instrument is equipped with special high
power pickups.
6.1.3 Noise
Audible hum can have several reasons, some of which are listed below:
•
Single-coil pickups are prone to collecting electrical interferences. Humbucker pickups
produce much less hum, which is why they got their name.
•
Your guitar is too close to electrical equipment. To reduce this type of hum, move the guitar
further away from the equipment.
GUITAR RIG MOBILE – 38
•
The guitar’s volume knob is set to a low level. Turn the knob up. If your guitar has more than
one volume knob, make sure to check all knobs.
• You are using a non-shielded or broken guitar cable. Your guitar’s shielding may also be
insufcient. Try replacing the cable with a shielded model rst. If this does not help, you
should consider having your guitar’s electronics serviced and shielded by a professional.
If you’re experiencing hiss, the input level of the GUITAR RIG MOBILE I/O might be too low.
Turn up the instrument’s volume or increase the input level on the GUITAR RIG MOBILE I/O.
For more information on setting the input level, see section 4.4 (Windows XP/ Windows Vista)
or section 5.4 (Mac OS X) of this manual.
6.1.4 Ground Loops
Ground loops (usually perceived as a hum or buzz) are a common problem when multiple
electrical devices are connected to the same power circuit. The following steps should help
to eliminate them:
• Disconnect all devices you are not currently using, e.g. peripheral devices you may have
connected to your computer (external data storage, CD burners).
•
Hook up a DI box behind the GUITAR RIG MOBILE I/O outputs. Most of these boxes have
a ground lift switch, which allows breaking the ground loop and eliminating the noise.
6.2 Hardware-Related Problems
Check the Native Instruments website and the NI Service Center for updates of the GUITAR
RIG MOBILE I/O driver and more information.
6.2.1 Driver Issues
Make sure that the GUITAR RIG MOBILE I/O is connected to the computer and open the
Driver Control Panel. See the intro to this chapter on how to nd the Control Panel.
GUITAR RIG MOBILE – 39
If the Control Panel is missing, the driver is most likely not installed at all. In this case, please
re-install the driver as described above.
If all the drop-down menus of the Control Panel are grayed out, the GUITAR RIG MOBILE
I/O is not recognized by the driver. Something might be wrong with the USB connection, see
the following sections for details.
6.2.2 USB Issues
GUITAR RIG MOBILE I/O is a USB 2.0 interface and will not work on a USB 1.0/1.1 port.
Always connect it directly to a USB 2.0 port on your computer. The port needs to fulll the
minimum power specication for a USB 2.0 port (500 mA). On certain computers, the USB
2.0 ports do not meet the ofcial USB 2.0 power specication. In this case, you may see a
message, saying that there is not enough power available to operate your device. The GUITAR
RIG MOBILE I/O may produce crackles or may not work at all.
• If your computer is unable to supply the necessary amount of bus power, try connecting
your GUITAR RIG MOBILE I/O to a USB 2.0 hub with external power-supply. Avoid connecting other devices to the hub, as every bus-powered device will diminish the total amount of
power available.
•
In case of failures, it is useful to check if GUITAR RIG MOBILE I/O works if you disconnect
any other USB device from the computer.
•
If you are experiencing audio dropouts or other problems that may be related to the USB
connection, try connecting the GUITAR RIG MOBILE I/O to another USB 2.0 port.
•
A bad USB cable can be responsible for audio dropouts and/or other connectivity problems.
Try using a different cable bearing the ofcial USB logo, in some cases using a shorter
cable might help.
•
If you are experiencing problems with GUITAR RIG MOBILE I/O crashing or performing
badly on a Windows machine, the rst thing to do is to disable power management for the
USB hubs, which is turned on by default. Go to the Device Manager (Control Panel > System
> Hardware) and right click a USB hub to bring up its properties. On the Power Management
page, uncheck all boxes. Repeat for each hub and reboot.

6.2.3 Using GUITAR RIG MOBILE with a Laptop
Please check if your computer is suited for handling real-time audio processing without dropouts. There are a couple of freeware tools to analyze your system, for example:
www.thesycon.de/deu/latency_check.shtml
Start the tool with the GUITAR RIG MOBILE I/O disconnected. In case your computer is unable to handle glitch-free audio processing, the tool will show red latency bars and report this
in the box on the bottom.
In general, it is not recommended to use laptops with shared-memory graphic cards. You will
need all the memory and processing power available for your audio project.
There are ways to optimize your laptop’s audio performance:
•
It is not recommended to run the laptop on battery, as power management might slow the
clock rate of the CPU down to save battery.
• Disconnect all unused hardware (e.g. printer, scanner). This will increase the amount of
processing power available for your music software.
•
Laptops often are equipped with built-in devices which disturb audio processing, most commonly a network adapter or a wireless LAN card. You might need to disable these devices
while working with GUITAR RIG MOBILE.
