Yamaha has extended its open architecture signal processor line with the launch of the MRX7-D, offering simple, flexible control for complex, high-capacity sound systems in hotels, ballrooms, houses of worship, schools, libraries, theatres, convention centres and conference rooms, among potentential applications.
Complementing the CIS range’s MTX series of fixed architecture matrix processors, 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 systems. Sixteen channels of Yamaha’s proprietary YDIF I/O and 64 channels of Dante I/O ives a total simultaneous I/O capacity of up to 110 inputs and 104 outputs.
YDIF delivers 16 bidirectional channels of audio and word clock transmission via Cat5e 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, Dante allows connection to Dante-enabled products in larger system applications.
The MRX7-D delivers 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.
Dan Dugan auto mixing has been a hugely popular feature of recent Yamaha digital mixers and it is included as standard on the MRX7-D. The first pro audio product to include this technology, it addresses the growing need to protect privacy in conference rooms and meeting areas, using an original sonic masking technique created from human voices to mask the intelligible content of speech. The MRX7-D includes the ability to generate this unique proprietary algorithm, and then to control and distribute it.
Featuring RS232C and Ethernet for 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. Fast, straightforward set-up is available via Yamaha MTX-MRX Editor software.
‘After we launched the MTX Series, we received many requests for open architecture products,’ says Ken Hiraoka, Yamaha Pro Audio Department Manager. ‘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.’
