DESCRIPTION

Introduction

The iMUX4 Microphone Multiplexer is the perfect instrument to expedite the testing,

adjustment, and documentation of the acoustically averaged frequency response of cinema

theaters, home theaters, churches, halls, banquet rooms, meeting rooms, clubs, or any other

venue in which great sound in the least amount of time is a requirement. The iMUX4 features

common XLR input and output microphone connections.

Because room resonance modes cause

different low frequency response in different

parts of any small room, equalizing the

response for multiple listening positions can

be a long process of repeated measurements at

multiple locations and change-and-check

equalization adjustments. Adjusting for

smooth response in just one or two listening

positions may leave other positions with

uneven, boomy, or wimpy bass response.

Averaging multiple measurements manually

is time-consuming and doesn't give you a

Features

 Provides a single, spatially-averaged acoustic input from up to four microphone positions

for Real Time Analyzer measurements.

 Provides a continuously updated average measurement of the overall response of the

listening area to allow easy equalization adjustments and average response documentation.

 Avoids the problem of making room adjustments based on the acoustic response of just a

single point in a room or of manually averaging measurements to determine needed

adjustments.

 Performs four microphone multiplexed sampling, as used by all major cinema/home

theater organizations, for a good average of overall room response.

 Measure the averaged output of two, three, or four attached microphones, or monitor

individual microphones for gain equalization.

 Internal microphone supply voltages and preamps eliminate the need for extra boxes and

simplify setup.

 Portable, battery-operated design eliminates the need for AC power connections.

 Unit power is controlled by phantom voltage from the connected RTA.

real-time display to immediately indicate

results of room adjustments.

The iMUX4 Microphone Multiplexer, with a

high resolution RTA, provides measurements

of the average response of a listening room or

multiple listening positions. This allows you

to position subwoofers or adjust equalizers as

you immediately see the measured results of

your adjustments. When you complete your

adjustments, you can store one RTA

measurement to document the average

response of the room.
