Provide the functions for effectively and efficiently holding conferences
Dugan Automixer: Prevent feedback and unwanted pickup with multiple microphones
Feedback and unwanted noise pickup can be difficult to control at corporate meetings and panel discussions where multiple microphones are used, often resulting in impaired sound quality and intelligibility. The Dugan Automixer automatically increases the gain of microphones that are in use while reducing the gain of unused microphones. It also keeps track of the relationship between individual inputs and the overall input level to ensure ideally consistent mixer gain. A safe feedback margin and optimum signal-to-noise ratio are maintained at all times.

-
Dugan Automixer 1
When nobody is speaking the input level at all microphones is low and the gain is equal. Rather than being muted, gain is distributed equally between all microphones.
-
Dugan Automixer 2
When one person is speaking the gain of that person’s microphone is instantly increased to 0dB while the gain of the remaining microphones is lowered. The same occurs when any other one person is speaking.
-
Dugan Automixer 3
If two people speak simultaneously the gain distribution between the active microphones is adjusted to achieve consistent overall gain, while the gain of the remaining microphone is lowered.
Acoustic Echo Canceller: Eliminate remote conferencing echo for maximum intelligibility
In remote conferencing situations speech from the remote location emanating from the local speaker can be picked up by the local microphone and returned to the remote location in addition to the local speech. This type of echo can significantly degrade the intelligibility of the sound heard at the remote location. The Acoustic Echo Canceller effectively suppresses this type of unwanted echo, maximizing clarity and intelligibility. The sound received at the microphone is compared with the sound emanating from the speaker and analyzed. An adaptive filter is employed to subtract the speaker output from the microphone input, preventing the speaker output from being returned as an echo by the microphone. Please note that this function is not designed to eliminate the room’s own acoustic reflections or reverberation.
* The Acoustic Echo Canceller is available in version 2.1 and later.
Speech Privacy System: Keep confidential information in the conference room
The need to protect privacy in conference rooms and meeting areas, particularly in financial or medical institutions, is a growing concern. The Speech Privacy System uses an original sonic masking technique to prevent leakage of confidential information. Rather than masking the conversation with high volume noise, an “information masking tone” synthesized from elements of human speech using an original process effectively camouflages spoken information. This approach allows the information to be protected by relatively low volume masking, helping to maintain the comfort of the conference environment. Sound synthesized from human speech renders conversation unintelligible to eavesdroppers. This function does not silence the sound of the conversation.
Revolabs Control Component
Yamaha and Revolabs codevelopped the mute link function, which enables mic muting of the Yamaha MRX7-D by ON/OFF button action directly from the Rebolabs Exective Elite - the local muting is disabled. Even when muted, the signal from the microphones is constantly sent to the AEC Module of MRX7-D to monitor the acoustic environment which speeds up AEC learning. This function greatly helps to reduce the chance of echo before the microphone is in use.
*This function requires on coming Executive Elite firmware version 1.1.6. and later
Control

A Versatile Range of Audio Functions
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.
* MTX-MRX Editor Ver.2.1.0 and later.
** MTX-MRX Editor Ver.2.2.0 and later.
*** Included in MTX-MRX Editor Version 3.2.0 and later.
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.

Dugan Automixer
By using the Dugan automixer, the input gain on microphones being used is automatically increased, while the gain on mics, not used, is decreased in order to reduce ambient noise leakage. This enhances the clarity of the sound. No specialized technical knowledge or skill is required—the mic gains are adjusted automatically.
* Version 3.0.0 and later, the number of Dugan automixer input channels has been expanded up to 24 channels.

-
Dugan Automixer

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.

-
AEC ( Acoustic Echo Canceller )
In remote conferencing situations, speech from the remote location emanating from the local speaker can be picked up by the local microphone and returned to the remote location in addition to the local speech. The AEC component can prevent this problem effectively. Let’s see how it works.
Speech Privacy
This function mixes environmental sounds and masking sounds to make it difficult for people nearby to overhear conversation in a specific location. Although there are two outputs for each mixed signal, these two consist of an output without offset and an output with offset. By assigning these two outputs to alternating speakers, you can reduce the unnatural sensation of skewed phase where the sound overlaps.
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.

-
FBS ( Feedback Suppressor )
This video will explain how the FBS on MRX and MTX processor works to prevent feedback effectively.
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.

Audio Detector
Audio Detector is a function that detects audio signals. By registering the detection indicator to the GPI Output, a signal can be output from the unit's GPI [OUT] connector when an audio signal is detected.
Summer
Summer is a Mixer component that simply mixes multiple input signals. It can be used as a simple mixer, such as combining faders and summers flexibly, or simply converting stereo signals into mono signals. There are 4 types of inputs of Summer, 2, 4, 8, and 16 lines, and the output is 1 line.
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.
