The Azrieli Sarona Tower, which rises 61 stories (more than 780 feet) into the Tel Aviv, Israel skyline, now hosts a new 230-seat auditorium for the Tel Aviv campus of the Continuing Education Division of the Technion — Israel Institute of Technology. The venue, located on the tower’s 29th floor,  incorporates AV equipment to facilitate the institute’s advanced research activities.

The auditorium is suited for lectures, presentations, and conferences, which are supported by an audio system designed by Erez Or of OR-TECH and implemented by system integrator Ardan Control-Tech that leverages the AES67 standard to knit together equipment from four different vendors onto a single IP network. At the heart of that audio system lies a Symetrix Radius NX 12×8 AEC-1 DSP module.

Technion is the country’s oldest university, having been founded in 1912, 35 years before the State of Israel was established. Considered one of the world’s top technical schools, the institute offers education and conducts research in nearly every branch of engineering, from aerospace and biomedical to nanotechnology and, of course, computer science. From its home campus in Haifa, Technion expanded to Tel Aviv in 1958. More recently, it added a campus in New York City in conjunction with Cornell University and a technology institute at Shantou University in Guangdong province in collaboration with China’s Li Ka Shing Foundation.

The Azrieli Tower, Israel’s tallest building, opened in 2017, making Technion’s outpost in the building all very recent construction. The Radius NX 12×8’s interfacing and feature set provided a simple yet effective way to address all of the installation’s audio needs, says Hanan Etzioni, director of multimedia for equipment supplier Dan-el Technologies. “The Radius NX 12×8 gave us a total overall solution,” he explains. “It includes both Dante networking and AES67, plus echo cancellation, and can host two USB inputs we used to interface the echo cancellation processing to the video conferencing system.”

The auditorium can be divided into two separate spaces with good acoustic isolation, enabling events to run simultaneously in both halls. Each is configured as its own zone in the Radius NX 12×8, and each hall sports its own podium. Mounted inside the podiums are substantial complements of equipment, including Attero Tech unD4I-L Dante interfaces. The podium microphone uses one of the unD4I-L’s four balanced mic/line inputs, leaving three more inputs for carry-in equipment or additional microphones.

Another zone is configured in the Radius NX 12×8 to serve the lobby area, which houses a cafeteria, seating areas, and a video wall with eight displays that are used for digital signage and content from the auditorium. A fourth output feeds the lobby zone signal to a subwoofer in the lobby area. The 12 analog inputs and 8 analog outputs on the Radius NX 12×8 are supplemented by a Symetrix xOut 4 Dante-enabled analog I/O expander, adding four more balanced analog line-level outputs.

The Radius NX 12×8 is fitted with two options to increase its power: an AEC coprocessor module for echo cancellation and a Radius USB audio card in its expansion slot. The expansion card and the unit’s onboard USB audio port interface with the two computers running Zoom software for video conferencing.

One of the most notable aspects of the auditorium installation was its smooth integration of networked devices from multiple manufacturers. “We were able to make equipment from Symetrix, Attero Tech, Stewart, and Atlona operate as one system based on AES67,” notes Etzioni. “It was the first time that level of integration had been achieved in the Israeli market.”
