Yamaha and Otari have announced to popularize mLAN digital network interface technology in the professional audio recording industry. In addition to this co-operation the companies have launched a joint project to develop the 2nd generation mLAN Chip to meet the specific requirements of high-end pro audio. Lightwinder ND-20 Digital Audio Distribution SystemOtari plans to make use of this chip in their development of the new network products in Otari's successful Lightwinder technology. Lightwinder systems have been used world-wide in many spectacular live applications, for example: at the FIS World Cup Ski 1996, at the American NFL-Superbowl 1997, at the Winter Olympics in Nagano 1998, and during the Summer Olympics in Sydney. Recent installations in Europe include Praha's Cultural Palace in the Czech Republic. mLAN licensees will begin receiving samples of the new chips in spring 2001.

About mLAN

mLAN is the new digital network interface technology advocated by Yamaha. It allows simple and efficient interconnection of audio/video equipment, electronic music instruments, PCs and other electronic devices by a single cable. Employing the industry standard IEEE1394 high-speed serial bus to carry audio and control data, mLAN simplifies system interconnection and enables users to easily execute sophisticated configurations. A modern, multi-media studio environment in which audio/video equipment and computers are used together, demands for general purpose communication which can handle audio, video, and computer signals by a single media and with single connection. The IEEE1394 and mLAN meets this requirement in highly sophisticated ways. Musicians and recording engineers utilising the new technology will experience an uncompromized new level of creative flexibility which helps to solve growing demands of Audio/Video/MIDI data transmission.

Joint Development Project

The objective of the joint development project is to enhance the functionality of Yamaha's existing 1st generation mLAN chip, mLAN-PH1. The chip is responsible for the interchange of all digital audio data formats and the IEEE1394 bus that conform to the "Audio and Music Data Transmission Protocol" (A&M Protocol). Yamaha and Otari intend to create a new generation chip, mLAN-PH2, which is capable to handle 4x the channel capacity and features 32 input and 32 output channels at 24-bit/48 kHz. Up to 4 chips can be connected in cascade with a single  Link-Layer chip so that up to 128 input and 128 output channels can be processed simultaneously on a single unit. Moreover, the new chips become compatible with the industry standard's current highest speed of 400Mbps, enabling the network to handle approximately 200 channels of audio in total. Channels are halved with 96 kHz signals.
