StealthPedal™ CS
2.2 StealthPedal Software Installation Introduction
StealthPedal system is a Hardware/Software combination. In order to use
StealthPedal either live or in the studio you will need a Mac or PC computer
(check Installation and Authorization manual for system requirements).
You need to install on your computer all software included with StealthPedal
to get the best possible user experience. There are three main software components you need to install first to properly operate StealthPedal:
• AmpliTube Software
• StealthPedal System Drivers (will be automatically installed during
the AmpliTube Software installation process)
• StealthPedal MIDI Control Application (refer to the StealthPedal
MIDI Control User Manual)
2.3 AmpliTube and StealthPedal System Drivers Installation
To properly install the StealthPedal, please do not connect the StealthPedal unit
to the computer until after following these few steps:
IMPORTANT: NEVER CONNECT THE STEALTHPEDAL TO AN INTERNAL OR
EXTERNAL USB HUB. PLEASE ENSURE YOU ARE CONNECTING STEALTHPEDAL
TO A DIRECT USB PORT ON YOUR COMPUTER (as an example on most desktop
PCs you will need to use the USB ports on the back of the machine, not on the
front as these are most probably connected to an internal hub).
For further reference on AmpliTube installation, please refer to Installation
and Authorization manual.
Windows®:
1. DO NOT connect the StealthPedal to the computer yet.
2. Insert the Installer CD into your computer drive.
3. Double click the file named ‘Install AmpliTube’ to install, register
and authorize the AmpliTube software and the necessary driver.
Follow the on-screen steps, and connect StealthPedal to an available USB port after the installation process has finished.
4. Double click the file named ‘Install StealthPedal MIDI Control’ to
install the StealthPedal MIDI Control software.
5. Load AmpliTube from: Start/Programs/IK Multimedia/AmpliTube.

2.7 StealthPedal Power On Check
StealthPedal is a USB Bus-Powered Device, and therefore needs no external
power supply.
StealthPedal has no Power switch, it powers up as soon as it is connected to the computer USB port. The red LED indicator on the side of your
StealthPedal (figure 2.3) will light up during device power up and operating
system boot. The green LED (figure 2.4) will light up when the initialization
will be completed, to indicate that your SteathPedal is ready to use.
figure 2.3 figure 2.4
If StealthPedal does not turn on please check that you have firmly inserted
the included USB cable into both StealthPedal and the computer. Should the
StealthPedal unit still refuse to power up please contact the IK Multimedia
tech support service.
If your computer gives an error about too high current draw from the USB
port you will have to use another port, directly connected to the computer
main board and not, for example, on the USB keyboard.
If the StealthPedal red LED remains ON and does not switch to green, you
need to install its drivers, or reinstall them if you have already done so.

2.8 The StealthPedal System Structure
This section explains how the StealthPedal system is structured and how its
components interact with each other.
The StealthPedal system consists of the following components:
• StealthPedal USB Floor controller and audio interface.
• Mac or PC host computer (see Installation and Authorization Manual
for system requirements).
• AmpliTube software installed on the Mac or PC computer.
• StealthPedal MIDI Control application.
StealthPedal is a USB Audio Interface and Controller specifically designed to
control IK Multimedia “Powered By AmpliTube” software modeling processors. StealthPedal is designed to work in combination with a core software
application called “AmpliTube” that runs on the host computer.
With StealthPedal you can go onstage comfortably, without heavy guitar
amplifiers and stomp pedals. The StealthPedal system gives you access to
hundreds of extremely accurate digital models of sought-after pieces of
gear, with a convenient small footprint, all in one device. Bring onstage the
sounds that you use in your productions, create custom controls for each
Patch and lots more. Go in the studio and remotely control all of your favorite
“Powered by Amplitube” processors within the AmpliTube “shell”. You will
be able to use StealthPedal as a remote controller for AmpliTube hosted by
your favorite Digital Audio Workstation as well as a high quality ASIO or
CoreAudio interface for your favorite DAW. Even if you don’t intend to use
StealthPedal as an audio interface (because, for example, you’re using Pro
Tools®) you can still use the StealthPedal as a flexible MIDI controller for
your software application(s), or for controlling AmpliTube as a plugin within
your DAW (Digital Audio Workstation).
StealthPedal™ CS
2 - Getting started
AmpliTube performs the following tasks:
• Provides audio input - output from and to StealthPedal.
• Provides Control Mapping for your StealthPedal for use with “Powered
by AmpliTube” software (for non-“Powered by AmpliTube” software,
please use the MIDI control application).
19
StealthPedal™ CS
2.9 Windows Control Panel
In order to open the Control Panel (figure 2.5), click on the “StealthPedal
icon” located in the Windows tray, (please check the Windows taskbar, usually located at the bottom next to the clock).
Control Panel description:
ASIO Buffer Size: sets the StealthPedal’s input/output latency. The smaller
the buffer size value is, the faster the response.
IMPORTANT: too small a buffer size may introduce audio pop and click
noises or CPU overload. Reliable operation highly depends on the performance and configuration of your system. Also, if there is an open audio
application that is using the StealthPedal’s ASIO driver, you will not be
able to change the buffer size value from the StealthPedal’s Control Panel.
In this case, you will need to either:
a) close the application before you modify the buffer size or
b) open the StealthPedal Control Panel from within the Audio Application
settings by clicking on the button that is usually named “Control Panel”.
ASIO Processing Time: adjusts the processing time of the internal ASIO
driver. The higher the value, the more reliable the system will be in
terms of audio quality at the expense of a slightly higher latency. Lower
values will further reduce latency but will increase the ASIO driver CPU
load, this could create audio pops and clicks at extreme settings.
figure 2.5
20
ASIO Driver: there are two options available: ‘Open’ and ‘Steaming’.
Open: ASIO driver is opened by an ASIO host application. This means that
the driver cannot be accessed by another ASIO host at the same time.
Streaming: ASIO driver is streaming audio data between ASIO host
and hardware device. This means that USB bandwidth has been
allocated for the input and output audio streams.
Input Gain Boost: when checked boosts the StealthPedal input sensitivity by
12dB. Depending on the instrument you’re using set this option so that you
get an input signal that is as high as possible without overloading or clipping.
Output Volume: controls the audio output volume of StealthPedal.
2 - Getting started
2.10 Mac Control Panel
On the Mac you can conveniently control your StealthPedal from the
“Sound” System Preferences. Open the “Audio MIDI Setup” (Applications >

2.12 Playing StealthPedal For The First Time With AmpliTube
Now that you have completed installing and connecting StealthPedal, and
all required software is installed, let’s play! Plug in StealthPedal, go to your
applications (or programs) menu and launch “AmpliTube”.
Open AmpliTube Audio MIDI setup window (figure 2.9) and select
StealthPedal as your audio interface, and you’ll be ready to go.

2 - Getting started
figure 2.9
If you want to control AmpliTube parameter with StealthPedal controls,
select the StealthPedal device on the top right corner of the AmpliTube
interface and click the ON button right close to it (figure 2.10).
For additional information on how to setup AmpliTube check the AmpliTube
User Manual.
The AmpliTube default audio settings are optimized for low latency and
good performance. The default audio settings for the StealthPedal audio
interface are:
• Windows: 144 samples buffer-size, 48 kHz sampling rate.
• Mac: 128 samples buffers-size, 48 kHz sampling rate.
On most computers, these settings will deliver the optimal compromise
between low latency and great reliability. However, if you would like to
23
StealthPedal™ CS
change these settings in AmpliTube standalone, select:
Settings > Audio MIDI setup.
If you experience audio pops or clicks while playing, try increasing the buffer-size value to the next higher step. If your computer is very powerful and
the 144 or 128 value is working perfectly, you may even try setting this value
to 96 (Windows only) or 64 (Mac only) for an even faster response. However,
this is not advisable on many older and/or slower computers and should not
be used as a standard setting for live shows unless you can extensively test
for your audio signal to be clean and free from clicks and pops beforehand.

Chapter 3 Typical StealthPedal Setups and Connections
The following paragraphs explain how to connect StealthPedal in most common live or studio situations.
figure 3.1
3 - Setups and Connections
25
StealthPedal™ CS
3.1 Using StealthPedal in a Home Studio
Outputs
With StealthPedal you can set up a home studio with quality comparable to
many pro-quality studio environments. When playing in a home studio with
StealthPedal, one usually will plug the unit into a pair of studio speakers,
commonly referred to as “Studio Monitors” (figure 3.2). For best results it is
advisable (when possible) to connect StealthPedal to your Studio Monitors
with balanced 1/4” TRS cables. This will help minimize noise and lead to
the most enjoyable listening experience possible. Please check to see if
your Studio Monitors are capable of receiving a balanced (TRS) cable. If not,
you can use unbalanced (TS) cables. It is not strictly necessary to connect
StealthPedal to a mixer or monitor-controller because a convenient Volume
control is already present on the unit. You can also connect headphones to
your StealthPedal by using the 1/8” Phones jack.
26

3 - Setups and Connections
StealthPedal™ CS
Inputs
Connect your instruments here (figure 3.3). When you need to connect only
one mono instrument (guitar, bass etc..) use input #1 (L). For optimum signal
quality, please use high-quality cables. These are balanced high quality Hi-Z
inputs that automatically switch to unbalanced when a 1/4” unbalanced cord is
plugged, perfect for low-level unbalanced signals (like the one from an electric
guitar or a bass, passive or active). When connecting a 1/4” balanced (TRS) cord
the input is actively balanced and is perfect to connect any line-level balanced
output audio device to the StealthPedal.

27
StealthPedal™ CS
3.2 Using StealthPedal On-stage Direct to The PA System
Outputs
With StealthPedal you can play on-stage without heavy amps and cabinets,
feeding your processed mono or stereo signal directly to the PA system (figure 3.4). StealthPedal’s balanced outputs are capable of driving long cables
without noise (if the inputs on the receiving side are balanced). Also use
these connections when you are sending your signals to the monitor mixer,
if you are hearing yourself with wedges or with in-ear monitors. The PA
engineers will then split the signals to be sent to the front of house mixer.
You don’t need any D.I. boxes because the StealthPedal balanced outputs are
designed to be connected directly to your mixer or PA system.

3.3 Using StealthPedal On-stage With One or More Guitar Cabinets
Outputs
With StealthPedal you can play live without amps and cabinets, but if you
prefer using real guitar cabinets you can do that easily as well by using a
mono (or stereo if you have two cabinets or a stereo one) power amp (figure
3.6). We recommend using a tube-based power amplifier designed specifically for guitar or bass as this will preserve the tone of AmpliTube better
than solid-state power amplifiers. However, solid-state amps will work
without problems and may be used as well.
