MRX7-D

MTX-MRX Editor: Dedicated Software for Total Sound System Design

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.

Flexible & Expandable

MTX-MRX Editor is more than just a controller for the MTX and MRX series processors. It allows central management of power amplifiers, external controllers, and other system components as well. Since control is carried out through a digital network, system alterations and expansion are easy, and devices added to the network via a single CAT5e cable can be quickly configured from the MTX-MRX Editor. It is also easy to add DCP series or other remote control panels to provide program change, volume adjustment, and other functions at any convenient locations.

For installations ranging from compact to expansive, this one application offers versatile control over audio input and output as well as the audio signal itself, providing enhanced efficiency and versatility from initial system design through installation to day-to-day management and operation.

An Intuitive Graphical Interface for Sound System Design

Dedicated Software for Total Sound System Design

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. The MTX-MRX Editor provides comprehensive, intuitive tools for designing sound systems from input to output.

1) Features for a Wide Variety of Applications

The MRX7-D offers a range of features for installed sound systems in the form of “components” that can be combined and configured as required: faders, switches, matrix mixers, source selectors, graphic EQ, Dugan automatic mixing, speech privacy, echo cancelling, and more.

Ambient Noise Compensator

Ambient noise can vary considerably throughout the day and on different days of the week, making it necessary to adjust background music and announcement volume accordingly. The Ambient Noise Compensator takes care of those adjustments automatically, setting background music and announcements to optimum levels at all times.

Combiner (Room Combiner/Room Combiner plus Automixer)

This component is ideal for managing the separation or combination of partitioned spaces in banquet halls as well as zones in open retail spaces, for example. Up to eight zones can be controlled with just one component. Two types of combiner component are provided: Room Combiner, and Room Combiner plus Automixer. The latter additionally features Dan Dugan Automixer functionality.

Speaker Processor

In addition to provision for up to 4-way crossover, this speaker processor component includes delay, 6-band parametric equalizer, limiter, and other functions. Data created by the user can be stored in a Library for instant recall whenever needed to accommodate changes in the speakers being used.

Matrix Mixer

A variety of matrix mixer components are provided, from a small 2x2 type up to a large 64x64 matrix for more complex mixing needs.

Feedback Suppressor

The Feedback Suppressor can effectively eliminate troublesome microphone feedback in a wide range of situations. Both a fixed-frequency type and automatic feedback frequency detection type are provided, each featuring 7 bands for a total of 14 suppression bands.

Scheduler

Any function can be triggered at any preprogrammed time. Used in conjunction with the built-in SD memory card slot the Scheduler can be used to schedule playback of specified audio files.

Acoustic Echo Canceller

AEC (Achorstic Echo Canceller) component reduces acoustic echo caused in a teleconference and offers better quality of sound for your meetings and conversations.

Revolabs Control Component

The Revolabs control component allows the mute control from Revolabs Executive Elite Series digital wireles microphone systems. The AEC can always learn from the reference while the Executive Elite Series is muted. Up to 48 microphones can be controlled using the components.

*This function requires on coming Executive Elite firmware version 1.1.6 and later.

Feedback Suppressor (Notch FBS / Pitch Shift FBS)

These components can effectively prevent feedback caused by speaker output being picked up by one or more microphones and re-amplified in a continuous loop. Feedback is not only hard on the ears, but can actually damage speakers as well. The first step in preventing feedback is to keep speakers and microphones away from each other. But when even the most meticulous positioning doesn’t prevent feedback, Feedback Suppressor (FBS) functions can help to maximize the feedback margin. The MRX7-D includes Notch FBS and Pitch Shift FBS components. The Notch FBS component uses a 7-band notch filter to attenuate feedback, while the Pitch Shift FBS stops feedback loops by shifting the pitch of the feedback frequencies slightly.

Delay Matrix

This matrix mixer shows input channel to output bus assignments arranged in a checkerboard pattern. Group balance and delay can be adjusted individually for each output buss.

Effect

Four effect programs are provided: Reverb Hall, Reverb Stage, Karaoke Echo, and Vocal Echo. These effects can be useful at banquets or events to add ambience to musical performances and generally enliven the acoustic environment.

Ducker / Paging Ducker

The Ducker component reduces the volume level of other channels when audio input is detected at a specified “KEY IN” channel. If a microphone input is specified as the KEY IN channel while other channels are receiving output from a background music source, for example, the level of the background music will automatically be reduced whenever an announcement is made via the microphone, and then return to normal when the announcement ends. The Paging Ducker adds a TRIGGER function that allows prioritization of trigger inputs.

Transmitter / Receiver

This component allows wiring between components at different locations on the design sheet to be hidden in order to reduce on-screen clutter and improve legibility. Transmitter and Receiver components having the same component label are connected “in the background” so that the corresponding wires do not appear on the screen. A single Transmitter component can be connected to multiple Receiver components. The component label and number of channels are selected when placing the components on the design sheet. New component labels can be entered manually, or existing component names can be selected from a list. Select the number of channels that matches the required connections.

2) Features for Enhanced Usability

Trace Signal Path

This function graphically displays the audio routing and channel on/off status within configurations, making it easy to pinpoint causes of common problems such as undesired audio output or no audio output.

User Defined Block

Components and related wiring can be assigned to User Defined Blocks. By consolidating multiple components and connections into easily manageable blocks, organization on the design sheet becomes more comprehensive while the ability to copy blocks makes it easier to duplicate complete functions in multiple channels, for example. As of the V2.2 update a User Defined Blocks PIN code can be used to prevent the configuration and parameters from being displayed or edited for maximum safety and security. Input/output components within blocks can be rearranged as required, adding significantly to overall system flexibility.
