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.
Features for a Wide Range of Installation Needs
AEC (Acoustic Echo Canceller) for remote conferencing systems, automatic mixing for multiple microphone inputs, a speech privacy function that can mask conversations in hospital or corporate systems where confidential information must be protected, and more. The MRX7-D offers a comprehensive range of components that offer effective solutions for a variety of issues faced in today’s audio installations.
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.
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.
Systems 1: Automatic mixing System (Meeting room, Convention center etc)
In a meeting room or a convention center where a number of microphones are used, MRX7-D Dugan Automatic mixing function can manage the level of each microphone, achieving better clarity in sound and suppressing unwanted feedback. At the same time, in combination with other functions, the MRX7-D can offer comfortable sound environment.
Systems 2: Remote Conference System (ex.Conference room)
Utilizing AEC function of MRX7-D, multiple participants in separate meeting rooms can join a remote teleconference. PA system in a meeting room can be operated via an iPad with ProVisionaire touch. (In addition, Speech Privacy System in MRX7-D can be utilized if confidential subjects should be avoided from leaking outside of the room.)
Systems 3: Speech Privacy System (ex. Hospital)
MRX7-D Speech Privacy System is useful for the areas such as patient encounter rooms in a health center, pharmacy or bank windows where confidentiality is prefered. MRX7-D can also distribute the BGM in those areas. With DCP series control panels, you can individually set and adjust the sound of each room.
Systems 4: Dante Audio Networking System (ex. house of worship, theater,)
MRX7D can mediate rooms via Dante networking, allowing audio to be shared in a variety of ways. An event taking place in room A can be auditioned in room B and C, and vice versa. For example, questions and answers can be passed back and forth between the rooms.
