Quick Start
iAudioInterface2 (iAI2) is a combination audio line input, line output, digital optical output,
headphone amp, and microphone input accessory for iPhone® 4, iPod touch® 4, and iPad®. It
connects to the attached iOS device using a digital audio link for lowest noise and highest quality
audio.
Hardware Requirements
iAudioInterface2 is designed to work with iPod touch® 4, iPhone® 4, or iPad® running OS 3.0 or
later.
App Compatibility
iAudioInterface2 is compatible with AudioTools, and many iOS Apps which play, record, or process
audio. While we have tested iAI2 with many Apps and found that it works with many (including
Apple’s GarageBand), we do not guarantee compatibility with all Apple or 3rd party Apps. In
particular, the phone App on iPhone does not use dock connector audio, and will not work with
iAI2.
Installation and Setup
To install iAudioInterface2, plug it into the dock connector of any compatible iOS device. Hold the
plug parallel to the connector, since plugging in at an angle may cause the device to not recognize
iAudioInterface2. Make sure that you hear both latches click so that you know you have a firm
connection. Some third-party plastic outer cases have smaller openings for dock connector cables,
so make sure that the case does not interfere with the iAudioInterface2 connector, and that the
connector is making solid contact with the dock connector.
Note that it takes approximately 3 seconds for iAudioInterface2 to be recognized by your iOS
device. So, if you plug iAI2 in while AudioTools is running, wait for the confirmation box before
trying to use it.
Note that it is possible for the iOS device to find the accessory, but iAudioInterface2 not be fully
functional if the connector is not fully seated or was plugged in at an angle.
Battery Charging and Power
iAudioInterface2 always runs off its own battery, or the external power supply, if plugged into it. It
draws no power from your iOS device. Run time is 3-5 hours, depending on usage.
iAudioInterface2 User Guide Page 4

Your iOS device always runs off its own internal battery, unless iAI2 is connected and an external
power supply is plugged into iAI2. In that case, your iOS device will be powered from the external
power supply, and the iOS device internal battery will be charging.
See the power / charging section of this manual for more information.
App Installation
If you do not have the AudioTools App installed, when you connect iAudioInterface2 to your device
a prompt will appear, and you will be asked if you want to install AudioTools. This behavior is
normal and is a feature of iOS. Although AudioTools is not required to use iAudioInterface2, it is
recommended so that you can take advantage of all of its features.
Calibration
You can use iAudioInterface2 right out of the box, but for more accurate results see our calibration
section below for information on how to calibrate your iAudioInterface2.
Default Configuration
As shipped, iAudioInterface2 is in the following configuration, which is used in Apps other than
AudioTools:
•Mono Line Input, microphone input enabled, phantom power off, 0 dB gain
•Line input gain range -70dBu to +8dBu
•Stereo (headphone) output

These settings can be changed in the AudioTools App, see below for more information.
