InfoComm 2015: Yamaha reveals new signal processor

Designed to complement the CIS range’s MTX series of fixed architecture matrix processors, Yamaha has launched the MRX7-D open architecture signal processor at InfoComm 2015.

The model promises to deliver ‘simple yet outstandingly flexible control’ for sound systems in hotels, ballrooms, houses of worship, schools, libraries, theatres, convention centres, conference rooms and many other applications.

The MRX7-D features eight mic/line analogue inputs, eight analogue outputs and two stereo RCA inputs, with an onboard mini-YGDAI card slot allowing local I/O expansion and connection to other digital audio products. Also featured is 16 channels of Yamaha’s proprietary YDIF I/O and 64 channels of Dante I/O. The MRX7-D can feature a total simultaneous I/O count of up to 110 inputs and 104 outputs.

Yamaha’s proprietary YDIF delivers 16 bidirectional channels of audio and word clock transmission via standard CAT5e cable over distances of up to 30m. It allows cascading of multiple MTX processors as well as signal transfer to CIS series XMV power amplifiers via connections that are fast and simple to set up, significantly reducing installation times for contractors. In addition, the inclusion of Dante on the MRX7-D allows integration with a wide range of Dante-enabled products in larger system applications.

The MRX7-D promises significant benefits for conference applications, including onboard Dan Dugan automated mixing and newly-designed Acoustic Echo Cancellation (AEC), which will be capable of being controlled from Revolabs Executive Elite boardroom-ready wireless microphones via a future software update.

A further key feature of the MRX7-D is Yamaha’s patented Speech Privacy system which uses sonic masking techniques created from human voices to mask the intelligible content of speech.

“We have been very excited to work with Yamaha on the MRX7-D. Clear, understandable speech in audio and video conferencing has always been a challenge for users. The combination of the Dugan Speech System algorithm with Revolabs microphones will make the MRX7-D an unbeatable voice processing system in the commercial market,” said Dan Dugan, CEO of Dan Dugan Sound Design.

Featuring RS232C and Ethernet connectors to facilitate connection to a variety of external controllers, including those by AMX and Crestron, the MRX7-D can also be controlled by Yamaha DCP series control panels, the Wireless DCP app and Yamaha’s new ProVisionaire Touch app. Setup is available via Yamaha MTX-MRX Editor software.

Ken Hiraoka, Yamaha pro audio department manager commented: “After we launched the MTX Series, we received many requests for open architecture products. The MRX7-D answers the need for open architecture DSP design and adds another significant element to the CIS series of processors, amplifiers and loudspeakers. In addition, the collaboration with Revolabs and Dan Dugan Sound Design helps Yamaha to realise a new era for conference applications. We will further enhance this area with the addition of additional products in the future.”

The MRX7-D is scheduled to ship in the summer of 2015.
