A virtual press conference from Sound & Video Contractor


NEW YORK, N.Y.-Two new high-powered amplifiers manufactured by NEXO and powered by Yamaha will make their debut at Yamaha Commercial Audio Systems, Inc. Booth #318 during this year‘s AES Show in New York. The NEXO NXAmp 4×4 and 4×1 are among the industry‘s most powerful amplifiers and provide a cost-effective integration of command, control, protection and amplification of ALL NEXO loudspeaker systems. Using the legendary Yamaha EEEngine technology, the amplifiers offer sonic purity of conventional class AB, but with a heat dissipation equaling class D technology.

The UL-certified NXAmp models both feature four amplifier channels that can be configured in 2 x 2 bridge mode providing up to 4 x 4000W at 2 Ω per channel or 2 x 8000W at 4 Ω per channel on the NX 4×4 and 4 x 1300W per channel at 2 Ω or 2 x 2600W per channel at 4 Ω on the NX 4×1. The NX 4×4 is 4U high, contained in a 19 in. rack and weighs 49 lbs., and the NX 4×1 is 3U high, in a 19 in. rack space weighing 33 lbs. The NXAmp power supplies are full resonance-type with half bridge converters, and its unique design minimizes noise via ZCS (Zero Crossing Switch) technology. The NEXO NX 4×4 employs four times the structure of a mono amp to realize very high power with a low impedance load.

“The NX Amp series is a major breakthrough in high powered amplification for both the fixed installation and live sound markets, states Albert Cardenas, acoustic systems manager, Yamaha Commercial Audio Systems, Inc. “We have been seeing very positive reactions to the Tn Series amps in use with NEXO speakers and we know the market will be quite impressed with these new NEXO NX, powered by Yamaha, amplifiers.”

More than two years of research yielding significant DSP innovations, enable multiple voltage, current and temperature sense lines from the NX Amp output to protect both the amplifier and the power supply including power on/off protection, peak voltage and peak current limiters, VHF protection and more.

Front panel features include three amp status LED indicators, LED display, encoder, user control navigation buttons, volume and channel indicators, and mute and select buttons. NXAmp signal processing is identical on both models and derived from the NX242 TD controller features. The NXAmps have over three times the DSP capacity of an NX242 with an NXtension card installed. User control navigation buttons consist of System Selection, which allows control across all NEXO ranges, System Set Up, Protection, Delay, Input Patching, Output Gain, Volume Control, Save/Recall, Array EQ, Security Mode, and Remote Control (via EtherSound protocol and ES Monitor Software (with optional EtherSound card installed).

There are three rear panel control ports: one is an expansion slot for adding an ES100 EtherSound board, another is a serial communication port for firmware updates, and the third is a GPIO port for simple remote control and monitoring. Four NL4 output connectors are configurable to drive most of the NEXO products directly without the need of an I/O panel. This fully integrated drive package eliminates the cost of parts, time, and possible connection errors of signal, sense, and output wiring between the current NX242, conventional amplifiers, and I/O panels. Like the existing NX242 controllers, the firmware is updateable allowing the NXAmp to take advantage of new speaker set-ups and features as they become available.

Delivery of the NEXO NX Amps is expected January 2008.
