The Klark Teknik business unit of Telex Communications UK Ltd has purchased the assets of the SuperMAC and HyperMAC audio networking business previously operated by Sony Oxford, a division of Sony United Kingdom Ltd, effective September 2007. The assets include all the SuperMAC and HyperMAC technology implementations currently available from Sony Oxford.
SuperMAC technology is the basis of Audio Engineering Society standard “AES50-2005: AES standard for digital audio engineering – High-resolution multi-channel audio interconnection.
Klark Teknik will promote the use of AES50, SuperMAC and HyperMAC and license the use of the technology. Support for existing licensees will transfer from Sony Oxford to Klark Teknik. Compliance with the Audio Engineering Society patent policy will be unaffected. Klark Teknik will additionally seek standardisation for the HyperMAC technology.
SuperMAC and HyperMAC together create a high-performance audio interconnection and routing system, designed for a wide range of professional audio applications.
· Single cable duplex interconnection for audio and sample clocks
· SuperMAC offers up to 48 audio channels bi-directionally over CAT5 cable
· HyperMAC offers up to 384 channels bi-directionally over CAT5/6 or fibre
· Ultra-low fully deterministic latency
· Comprehensive error detection and management
· Ethernet physical layer audio data transmission
· Ethernet TCP/IP protocol compatible auxiliary data channel
Implementations of the technology are available as both FPGA cores and dedicated chips.
SuperMAC and HyperMAC are used extensively in the Midas XL8 digital mixing console to provide a highly flexible audio routing and distribution network. As well as licensing the technology, Klark Teknik will be launching a range of products using this networking technology, beginning with the DN9696 High Resolution 96 track/96 kHz live performance audio recorder to be previewed at PLASA 07. Further product announcements from 3rd parties are expected shortly.
John Oakley, Managing Director of Telex Communications (UK) Ltd, said, “SuperMAC and HyperMAC are by far and away the best networking technology for live performance use. They are totally deterministic with very low latency over multiple network segments and offer very high reliability and redundancy. The high channel capacity coupled with the ability to carry standard TCP/IP messages cannot be matched by any other technology. Klark Teknik is proud to be the new owner and promoter of this exciting and practical technology. It is particularly important that this is an AES standard and open to all.”
Morgan David, Divisional Director Research and Development at Sony Professional Solutions Europe a division of Sony United Kingdom Ltd., said,“”We are delighted to have been able to complete this sale to Klark Teknik as they have been our strongest supporter in developing the AES50 standard and adopting the SuperMAC technology into their product. It was our top priority to identify a new owner who would be actively committed to the development of the AES50 standard, both in terms of technological progress and also through active licensing and support to the Pro Audio industry as a whole. Given that we had decided Sony could no longer give our Audio Networking business the investment and focus it needed, this is undoubtedly the best outcome we could have hoped for as it secures the future of this standard for the industry.”
