Digital Harmony Technologies Inc., a developer of digital audio technologies, today announced the availability of the first commercial products containing its BiDAT(tm) technology. JBL Professional's new intelligent sound reinforcement system called EVO(tm) is a complete plug-and-perform sound system that uses BiDAT transceivers to send digital control data over standard audio cables, without any audio interference. EVO enables a new era of digital control over room equalization, feedback suppression, delay settings and amplifier dynamics via in-speaker BiDAT transceivers.

Digital Harmony's patented, low-cost BiDAT transceivers support bi-directional data transmission at rates of up to 56Kbit/s, over more than 1000-feet of low-cost audio cables. Data transparently coexists on the same cabling as the audio signal. BiDAT transceivers allow speakers to communicate with decoders and amplifiers, without the complexity and expense of a sophisticated network communications interface.

JBL, Digital Harmony's initial BiDAT licensee, uses the transceivers to send IR volume and signal processing data to powered speakers. In addition, the EVO system contains integrated heat and feedback sensors that automatically detect and transmit fault conditions to the front-of-house hub. With such advanced use of technology, JBL's EVO is poised to become the system of choice for all-in-one sound reinforcement systems for schools, houses of worship, arts centers and many other small and mid-sized installations.

BiDAT transceivers are part of the growing Digital Harmony Studio(tm) portfolio of licensable professional audio technologies, which also includes DHIVA(tm) 1394 interface modules, WireFree(tm) wireless audio modules, musical DSP modules, and PAWS(tm) audio watermarking codecs. Digital Harmony's growing family of pro audio licensees includes Cirrus Logic/Crystal, JBL, Lexicon, Nippon Columbia, Peavey Electronics, QSC Audio Products, and TC Electronic.

"BiDAT is an elegant, low-cost solution for sending control data between speakers. It is an intelligent and natural complement to our 1394 and wireless interface modules, giving our partners a range of loudspeaker technologies second to none. We congratulate JBL on the release of their technologically-superior EVO system, and look forward to a long and prosperous product development relationship with JBL ," says Greg Bartlett, president of Digital Harmony Technologies.

"In the end it's all about helping the aspiring sound professional to achieve the best audio quality with the least amount of hassles," says Simon Jones, product manager at JBL Professional. "BiDAT from Digital Harmony is a key strategic piece of JBL's overall strategy to add this value to our professional sound installation offerings," he adds.
