Biamp was recently awarded a patent from the U.S. Patent and Trademark Office for burst mode technology used in several of its Tesira conferencing solutions.

Burst mode is a key element of Biamp’s single cable-connection platform, which provides superior audio performance and easy installation via standard Category cables. The patent covers an innovation that delivers higher peak output from amplifiers powered by PoE+ technology. During normal operation, the amplifier stores up power to be used during moments where higher output is needed. When peak power is required, to cover items like lower frequency, audio tracks, or louder speech, the amplifier’s power supply uses the stored energy to significantly increase output power for a short period of time.

“Tesira’s PoE+-powered amplifiers and Parlé microphones with integrated amplification feature our exclusive, and now patented, burst mode technology,” comments Biamp's EVP of corporate development, Joe Andrulis. “Burst mode allows us to deliver extraordinary amplifier performance using standard CAT cables, making it more efficient than ever to deploy great sounding conferencing solutions across the enterprise — from huddle rooms to boardrooms to training spaces.”

In the case of Biamp’s Tesira AMP-450 family, the devices can take the 25.5W delivered by PoE+ and generate peak outputs of up to 200W across four channels. "That’s enough to drive loud music in a large training room for 100 people," notes Biamp's Andrulis.

The burst power technology also enables Biamp to create powerful-sounding amplifiers in very compact and innovative form factors. For example, the Tesira AMP-450BP is small and light enough to be directly mounted to the company's Desono C-IC6 in-ceiling loudspeaker, which results in fast, clean installations. Similarly, a single AMP-450BP can drive up to eight C-IC6 loudspeakers using just CAT cables, meaning that a structured cabling crew can complete the entire above-ceiling audio rough-in for a conference room.

In the case of the company's Parlé TCM-XA ceiling and TCM-1A pendant microphones, the burst technology allows Biamp to include a 2-channel amplifier in the same enclosure as the microphone electronics. This reduces the total number of devices and network drops required for system deployment. The capabilities for streamlining system design and the installation process are further reinforced by the company's TesiraCONNECT expansion device, which delivers PoE+ power and streaming media for Biamp's Tesira conferencing products.

"Biamp’s combination of advanced technologies, elegant industrial design, and integration of the entire audio signal path — from microphone to speaker — onto a single cable type, ensures that Tesira conference rooms sound better, look better, and are easier to install than any other system," concludes Andrulis. "The addition of the powerful SageVue management tool makes monitoring and managing deployed systems a familiar and comfortable process for technology managers," he adds.
