The IE-45 Audio Analysis System from Ivie
 is a completely new, calibrated, handheld audio instrument delivering a broad
range of acoustical measurements.  A vivid color display imparts more information to the customer.. In-the-field functions
include real time analyzer measurements (RTA), sound pressure level (SPL) measurements, seat-to-seat level variation
measurements, strip chart recordings of sound level over time, polarity checking, audio frequency oscilloscope measurements,
Noise Criteria (NC/NR) measurements, a built-in signal generator, audio level volt meter, Spectrograph, and more. 
Optional  RT60, STI-PA, LEQ, Record, and other measurements and functions now available.

The IE-45 Digital Input Module interfaces via USB.  IE-45 software runs on the Windows®  XP™ platform.

Delivering accurate measurement data in a highly readable, user-friendly format, the IE-45 provides unsurpassed convenience
in a feature-rich package that offers complete portability.

Overview:

A calibrated, instrumentation-grade (TYPE I or TYPE II), audio analysis system built upon an open Windows Mobile 2005 platform.
Offering detailed Real Time Analyzer (RTA) and Sound Pressure Level (SPL) functionality including accurate and easy-to-use RTA,
SPL Monitor, Strip Chart Recorder, Polarity Checker, Oscilloscope, Signal Generator, Audio Level Volt Meter, RT-60 reverb and more.
All combined into an extremely convenient, brilliantly colored, Ultra-Mobile PC package.

Virtually unlimited data storage with integral 30 Gb hard drive for archiving and graphic reporting using free IvieXLS
(Microsoft Excel Template) software (included with any IE-45 purchase).

Battery life capable of running about 4 to 5 hours in full energy burn mode with the extended life battery option.

Inputs: Mic/Line Channel 1, Line Channel 2
Outputs: 3.5mm stereo jack

The IE-45 comes as a complete package. It includes the Samsung Q1 with charger, IE-45 Input module, Type 1 or 2 microphone
preamp combination, USB cable, custom acoustic analyzer software, IvieXLS© graphing and plotting software (requires Microsoft Excel),
and manual.

RTA (FFT-based):
-- Accuracy +/- 0.5dB
-- 1/1, 1/3, 1/6, octave bands from 20Hz to 20kHz
-- Max resolution of 2048 data points (diplayed at 240 freq. data points... much greater than 1/2 octave.)
-- Selectable weighting filters: Flat, A, and C weighting... and octave filters at 125Hz, 250 Hz, 500Hz 1 kHz, 2 kHz, and 4 kHz
-- Detectors: fast, slow, peak, impulse
-- Three display integration times (adjustable display decay 1, 2 and 3)
-- Peak detect and hold
-- Frequency detection display
-- Low freq. zoom (20Hz to 2kHz at 1Hz resolution)
-- Powerful averaging (continuous or trigger mode)
-- NC/NR
-- (F)STC, STC, (N)NIC, NIC
-- Easy subtraction
-- Multiple scratch pad memories
-- Unlimited storage capability

SPL Monitor:
-- 4 Digit readout with 0.1dB resolution
-- Large digital display with two user adjustable SPL threshold warnings
-- Bar graph display
-- Response modes: fast, slow, peak, impulse
-- Selectable weighting filters: Flat, A, and C weighting... and octave filters at 125Hz, 250 Hz, 500Hz 1 kHz, 2 kHz, and 4 kHz
-- Meets ANSI S1.4-1983 Type II with standard Ivie mic; Type I with optional Ivie mics (1133/1134) and preamps (IE-5P/IE-6P)

Seat-to-Seat:
Measure Seat-to-Seat SPL variation in all pass, several octave bands, with and without weighting. Easy to read graphic display
with digital and bar graph readout.

Strip Chart:
-- Unique strip chart display shows amplitude over time
-- User settable time scale from continuous to up to 8 hours
-- Acoustic Time Study Graph
-- Detectors: fast, slow, peak, impulse
-- Selectable weighting filters: Flat, A, and C weighting... and octave filters at 125Hz, 250 Hz, 500Hz 1 kHz, 2 kHz, and 4 kHz
-- Data can be stored to a log file and transported to a PC for manipulation and display

Polarity:
Using the IE-33's built in signal generator (3.5mm stereo jack) or using a separate compatible generator (CD with compatible
pulse comes with IE-33 purchase), easily check polarity of distributed and other speaker systems acoustically and electrically.

Scope:
-- Allows visualization of wave forms
-- Standard and XY
-- Dual trace

Signal Generator:

-- Pink noise
-- White noise
-- Sine waves
-- Square waves
-- Triangle waves

Audio Level Volt Meter:
-- Large analog and digital display
-- User selectable scale
-- Measures AC Volts, dBu, dBV and AC V
-- Detectors: fast, slow, peak, impulse
-- Selectable weighting filters: Flat, A, and C weighting... and octave filters at 125Hz, 250 Hz, 500Hz 1 kHz, 2 kHz, and 4 kHz
