IE-45 IM Inputs
Introduction
Congratulations! With your purchase of the Ivie IE-45, you not only have one of the most powerful, versatile, and
accurate audio spectrum analyzers available, but you also have an analysis system that is capable of expanding
as your needs expand. The supplied microphone is a Type II microphone, making the standard IE-45, a Type II
measurement system. For those needing Type I accuracy, two optional microphone preamplifier and microphone
capsule combinations are available to convert the IE-45 analyzer to a Type I measurement system. With reason-
able care, the IE-45 will provide a long period of useful service.
This manual is intended to familiarize you with the basic operations of the IE-45, and to whet your appetite con-
cerning some of its possibilities. It is in no way intended to be the total description of all the possibilities of this
unit.
The computer supplied with the IE-45 is a Samsung® Q1, Windows® XP machine. However, this specific com-
puter is NOT required. The IE-45 software will run on many Windows® XP machines with USB ports for connec-
tion to the IE-45 Input Module, as long as they have sufficient processing power and speed to run the software at
optimum performance. If you prefer to use your laptop, for example, simply connect the IE-45 IM to it using an
appropriate USB cable, load the IE-45 software and you’re off and running!
IE-45 Software Options
A number of different software packages are available for the IE-45. Each can be purchased separately and run
independently, depending upon your measurement needs. These software packages include:
IE-45 RTA: Comprehensive real time analysis software. Comprises multiple functions from RTA to
SPL meter, to oscilloscope, to volt meter and many others. The bulk of this manual is
dedicated to a description of the functions of this software package. Where appropriate, appli-
cations are discussed as well.
IE-45 Leq: Full Featured Leq survey software. This independent software package comes with its own
manual and a separate PC software package for formatting and printing measured data.
IE-45 RT-60: RT-60 measurement software. This software package runs within the IE-45 RTA software
package, but must be purchased separately.
IE-45 STIPA: Intelligibility measurement software. This software package runs independently.
IE-45 Record: Independent WAV file recording software. Recorded WAV files can be injected into the
IE-45 RTA software program for analysis.
Additional software packages will become available in the future as the functionality and measurement capability
of the IE-45 continues to expand.
IE-45 IM Inputs
As demonstrated across the page, the IE-45 Input Module (IE-45 IM) has four different inputs: Microphone (Mini
QG, 4-pin), two line level inputs (RCA /phono) and an additional line (SMA) input. Two of the four inputs can be
simultaneously active. The variety of input connectors allows for the convenient input of a number of different
signals from external devices.
For those wishing to remote the microphone some distance away from the IE-45, microphone extension cables
of varying lengths up to 200 feet are available from Ivie.
