AmpConnect ISCTM Instruction Manual Introduction 1
Introduction
AmpConnect ISCTM makes loudspeaker and microphone testing simpler AND more cost-effective. It
replaces an audio interface, an impedance box, amplifier, microphone power supply and digital I/O card with
one simple USB controlled piece of hardware. AmpConnect ISC provides all the necessary calibration,
voltage, & current signals to perform acoustic and electronic tests such as frequency response, sensitivity,
distortion, and impedance. It can also drive sound sources (e.g. mouth simulators) for testing microphones.
This reduces operator error as multiple hardware items are replaced by a single rugged, rack mountable
unit. The only connections required are a USB cable to the computer and cables to your device under test
and test microphone. AmpConnect ISC is fully controllable via SoundCheck which means that adjustments
of parameters such as gain can be included in test sequences. AmpConnect ISC is easy to calibrate, easy
to setup and is more immune to noise due to minimized connections. AmpConnect ISC can route/select all
test signals, and contains an integral power amplifier to drive the device under test (or mouth simulator).
Two selectable internal reference resistances to measure device impedance offer much simpler impedance
measurements than conventional methods. No additional external equipment is required to realize a
complete acoustic test platform for a wide range of devices – simply connect your device to AmpConnect
ISC and SoundCheck, and start testing.
Control
AmpConnect ISC can be controlled either using the switches on the front-panel, or remotely via a USB
connected PC. This makes it equally suitable for use as a standalone device (e.g., in a lab or during
production line setup), or with a PC on a production line. An eight-bit digital I/O port provides digital control
and/or status monitoring of external devices for operator feedback, test fixture control, etc.
Connection
AmpConnect ISC™ features an Internal Audio Interface and requires only a USB cable to interface with
SoundCheck.
Two user-selectable inputs enable 2 measurements to be made simultaneously. In the case of a
loudspeaker test, this may be an acoustic signal and an electrical signal such as impedance, or for
headphones two acoustical signals simultaneously. In the case of a microphone test a reference
microphone may be measured at the same time as the microphone under test for comparison purposes.
Two sets of output connections for the devices under test, either of which can be selected as the active
output, permit one test to be performed while simultaneously setting up a test on the other output to
increase production line testing throughput. A headphone output on the front may be used for testing
headphones or monitoring input signals.
Two separate inputs allow the output from an external electrical test signal (typically the output of a
measurement microphone) to be routed through and selected by AmpConnect ISC and communicated to
SoundCheck. This frees the operator from having to handle external signal switching during testing. Both
inputs provide voltage and IEPE bias, supporting transducers requiring either type of powering. The bias
can be removed to allow direct connection to a microphone power supply or preamplifier.
The amplitude of signals can be adjusted for maximum dynamic range without the need for external
amplifiers or attenuators. Both the reference input signal and the signal from the device under test, can be
attenuated by 10 or 20 dB, or amplified by 0, 10, 20, 30, or 40 dB before being output to SoundCheck.
Simplicity and ease of use has been carried through to the user display, with three-color LEDs on the front
panel (as well as a signal to the computer via the USB) to provide a clear visual signal to the user that the
reference, device-under-test, and power amplifier levels are operating within maximum dynamic range.

AmpConnect ISCTM Instruction Manual Installation 5
Installation
Requirements
zSoundCheck 10.11 minimum (or SoundCheck ONE) is required in order to control AmpConnect
ISC™ via USB
zThe SoundCheck computer must have an available USB 2.0 connection
Note: It is recommended that AmpConnect ISC be mounted in a ventilated rack mount enclosure for
proper cooling.
Software Installation
Important! Rockey Hardware Key only: Make sure the SoundCheck USB hardware key is not
connected to the computer. If it is connected while installing AmpConnect ISC or
SoundCheck, the hardware key could be destroyed. Do not unplug the hardware key
while SoundCheck is running. Doing so could destroy the hardware key.
Install SoundCheck first!
Before connecting AmpConnect ISC to a USB port of your SoundCheck System, SoundCheck must be
installed. The AmpConnect ISC driver installation is part of the SoundCheck software install process.
Important! As of SoundCheck 13, a new driver for AmpConnect ISC has been included in the
SoundCheck installation process. The new driver will not work in versions prior to
SoundCheck 13. To use AmpConnect ISC with SoundCheck 12 (and previously
supported versions), you will need to manually rollback the device driver in Windows
Device Manager. See AmpConnect Driver Rollback Procedure on page 1.
Important! After installing SC 14, prior versions of SoundCheck will not have control over the
device. Additionally, the serial number of the AmpConnect audio interface will not
be read properly which changes the name of the device in the Hardware Editor.

6 Installation AmpConnect ISCTM Instruction Manual
Prior to SoundCheck 13
AmpConnect ISC requires Microsoft .NET Framework 2.0 sp1 (or later). SoundCheck 11 and 12
include .NET Framework 2.0.
The SoundCheck 11 installation process will check to see if .NET Framework is installed. If not, you are
prompted to install the required application.
Note: An internet connect is required in order to download the Microsoft application. If the
SoundCheck system does not have internet access, the NET framework installer can be
download on a different PC and then copied to the system manually.
Once the installation has finished, you can connect AmpConnect ISC to
your SoundCheck system using the USB cable provided.
Windows will indicate that new hardware has been found, which shows
that the driver has been successfully installed. This may be displayed as
“AmpConnect ISC” or as “New HID Device”.
Swapping Devices
If you swap one AmpConnect ISC for a different AmpConnect ISC while SoundCheck is open:
zOpen the SoundCheck Hardware Editor
zOpen the AmpConnect tab
zClick Remove
zClick Add
zSelect the new AmpConnect ISC from the drop down list
Audio Device Settings
Do not connect audio interfaces through USB hubs. Connect directly to computer USB port.
AmpConnect Configurations
Units with S/N AC432 and after, operate at 44.1 kHz and 24 bit depth. (Prior to that S/N, 44.1 and 48 kHz
are supported)
