      Digital Control Panel – DCP Series

      DCP controllers provide flexible external control of several functions such as preset recall, levels, and SD card playback. The series comprises of three different models that feature various configurations of switches and volume knobs. DCP controllers are connected to MTX/MRX series by using a daisy-chain connection up to eight control panels. All three models are available in either US or EU standardized sizes, built to meet the specifications of most regions around the globe.

      Digital Contoroler Hub – DCH8

      DCH8 divides the control line from host devices such as the Yamaha MTX/MRX series into up to 8 lines. It allows for a flexible system structure, with a combination of star connections and daisy chain connections as a repeater between the host device and the control panels.

      DCP Series/DCH8 Connection Distance


      It is possible to connect up to eight units of DCP controller by using daisy chain connections of up to 200m. And, it is possible to extend the connection distance by reducing the number of DCP series that are installed as below. When using 2 or 3 DCP controllers in a commercial space which has a wide floor, a simple daisy chain connection is effective. When using more than 4 DCP controllers in a wide commercial space over more that one floor, a flexible topology (combining Daisy chain and Star connections) can help to extend the «total» cable length by combining a DCP series with DCH8.


      Wireless DCP

      The Wireless DCP app for iPhone or Android devices allows you to remote control the MTX/MRX series. Since the Wireless DCP has the same function as the DCP series, you can control the MTX/MRX series via your smart device at any place in the restaurants, banquet halls and so on. * Wireless DCP can be downloaded from Apple’s App Store and Google Play at no charge.(Apple, iPhone and iPod are trademarks of Apple Inc., registered in the U.S and other countries.

      Flexibility and Operation Ease

      As the scale and control requirements of an audio system grow, the number of devices required and overall complexity increase correspondingly. With the MRX7-D and dedicated MTX-MRX Editor software, input and output devices can be quickly arranged via a software wizard and internal MRX7-D processing components can be combined as needed. One simple software application provides everything needed for comprehensive system design and management.

      MTX-MRX Editor

      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.

      1) Device Layout Wizard

      In addition to the MRX7-D, the wizard allows MTX series matrix processors, XMV series power amplifiers, DCP digital control panels, and EXi8/EXo8 input and output expanders to be added and arranged as needed.

      2) Component Configuration

      The MRX7-D features a versatile range of built-in processing components: faders, ON/OFF switches, matrix source selectors, GEQ, Dugan automatic mixing, speech privacy, echo canceller, and more. Simply select the required components and arrange them via a graphical interface.

      3) External Controller Setup

      Parameters that will be available to the end user can be specified via the MTX-MRX Editor. A variety of external controllers can be accommodated to ideally match the requirements of each installation.

      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 pickup 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.

      Revolabs Control Component


      The mute link function with Revolabs Exective Elite Series digital wireless microphone system

      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


      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.
