Audio signals are connected via screw lockable Euro block connectors. A-to-D conversion is handled by high performance linear 24-bit converters. [. . . ] A-to-D conversion is handled by high performance linear 24-bit converters. Internally the signals are processed in 48-bit word length. The dynamic range is more than 117 dB. The AO-1 is an eightchannel analog output module for the NetmaxTM System Controller. As with the other modules, the AO-1offers eight high quality audio signals via screw lockable Euro block connectors. D-to-A conversion is handled by high performance linear 24-bit converters. Internally the signals are processed in 48-bit word length. The dynamic range is more than 118 dB.

The module provides a variety of microphone input functions, e. g. programmable gain, software-switchable PAD for line sensitivity and selectable +48V phantom supply per input channel. The 626 delivers extreme DSP horsepower -- enough to process 32 audio channels with FIR-processing -- plus other functions such as limiters, delays, and conventional EQs. This is revolutionary DSP, suitable to drive even the most sophisticated line arrays systems for ultimate performance and pattern control. Most Powerful Pro Audio Processor on the Market The 626 represents that state of the art for pro audio signal processing. Based on the technology inside the Electro-Voice NetMax N8000, this system has proven itself time and again in the most demanding installations and live performances. Ranging from The World Cup to Live-8, from the Houston Rodeo to Kenny Chesney's groundbreaking tours, NetMax has established itself as a proven, roadworthy tool that can take even the most state of the art PA systems to the next level. Now, NetMax itself advances to the next level with the 626. At the heart of the N80001500 is the new DSP-2 engine. Composed of three dual-core processors, the DSP-2 expands the total processing power of the 626 to 1500 MIPS. But it doesn't stop there: the unique modular nature of NetMax's means that each input or output card that is added to a chassis provides an additional DSP engine and another 100 MIPS of processing power. This means that a fully loaded chassis provides 1900 MIPS of processing-almost double the power of the original N8000. Combined with the optional CobraNet interface, NetMax's unique monitoring and supervision options, FIR-Drive, and the multitude of control options provided by IRIS-Net, the 626 represents the most powerful pro audio processor on the market! Full System Monitoring and Supervision Superior Audio Performance The highest level of audio applications demand the highest audio performance, and NetMax delivers.
