MTX série

Central Management of Multiple Sound Systems from a Single PC

MTX-MRX Editor is a software application that is dedicated to the setup and management of sound systems built around the MTX and MRX series signal processors. It can mix audio from microphones, CDs, MP3 and WAV files, deliver different content to multiple zones, set up timer-activated music playback and announcements, and much more. MTX-MRX Editor makes it easy to manage and distribute sound that is optimized for separate areas of a store or facility from a single computer.

Furthermore, in Ver 3.2, for example, in multiple facilities such as amusement parks and shopping malls, it is possible to manage multiple areas separately on multiple subnets for each zone by a single PC.

The MTX-MRX Editor software facilitates sound system design with a workflow that simulates standard installation procedure. An easy-to-use wizard lets you start by arranging the devices to be used in the desired layout, then processing components can be added wherever needed. MTX series matrix processors, EXi8 input expanders, EXo8 output expanders, XMV series power amplifiers, and DCP digital control panels can be added according to the needs and scale of the application. The MTX-MRX Editor provides comprehensive, intuitive tools for designing sound systems from input to output.

A Feedback Suppressor or FBS, is a function that prevents the unpleasant acoustic feedback that occurs when sound from a speaker is picked up by a mic and reamplified.

MTX features two types of FBS, Fixed and Dynamic. Fixed is ideal for installations where the microphones do not move and where the problem frequencies remain the same. If microphones are constantly moving then Dynamic FBS is more suitable as it can constantly update the settings to eliminate feedback.

AGC (Auto Gain Controller) is a function that automatically compensates the gain according to the input level, keeping a constant output level for an incoming signal whose level is changing. This can be very useful when there are people speaking at different levels or there are background music sources at different levels and there is no technician available to make manual adjustments. The AGC will smooth the output levels making the listener's experience more pleasurable.

1) When no one is talking

When no one is talking, the input level on all microphones is lowered, and the gain levels are set uniformly. At this time, rather than muting each microphone, the gain is distributed between three microphones, so that the total gain remains constant.

2) When one person is talking

When one person speaks, the gain of that microphone instantly rises to 0 dB, and the gain of the other two microphones is lowered. The same thing happens when a different person speaks.

3) When multiple people are speaking

When two people speak simultaneously, the gain level is automatically distributed between the two microphones so that the total gain remains constant, and the gain of the remaining microphone is lowered.

A Priority Ducker is a function used to automatically attenuate a zone's output level by a specified amount when the signal from a separate sound source exceeds its threshold. For example, it could be used to reduce the background music level when important emergency announcements are made so as to maximise intelligability.

An ANC or Ambient Noise Compensator will adjust system gain to compensate for fluctuating background noise levels. A typical example would be at a party when the ambient noise becomes so loud that music or announcements can no longer be heard. The ANC will raise the system volume to compensate.
