User manual ELECTRO-VOICE DH1202 DATASHEET

[. . . ] IRIS-Net enables you to process all or part of the audio signal in a central component like the NetMax N8000 or to conduct the processing and supervision remotely at the amplifier. This gives the system designer incredible flexibility in designing the system. You can now design the system for the ultimate in reliability or design for efficiency and value. The IRIS-Net solution gives you all the hardware and software pieces to accomplish both objectives. Open Architecture ­ Extensively Tested The IRIS-Net software platform has been extensively tested in a variety of venues. [. . . ] In addition, the N8000 can talk through its integrated CAN bus with any compatible IRIS-Net hardware such as the Electro-Voice RL/RT amplifier series. For even more flexibility the N8000 comes equipped with a GPIO network so it can control and be controlled through simple logic signals and contact closures. Beyond Audio Processing In addition to the sophisticated audio functions of the NetMax N8000, it is also equipped with diverse control functions. The clock /calendar scheduling system makes it possible to program one-time or recurring events. The schedule options are varied and can be set to occur annually, monthly, weekly, daily, hourly or even within smaller time intervals. In addition, daily programs can be set up. With the event control, reactions to certain events or system states can be configured including changing entire system parameters at the touch of a button or schedule. Full System Monitoring Faults in the device or in the complete NetMax system are detected automatically and can be displayed on the PC screen or transmitted to external sites if necessary. Faults and other events are recorded in an internal log file with date and time. In addition, you can define which types of errors or events should be recorded. The log can be read out and displayed on the screen at any time. When used in conjunction with Electro-Voice RL series amplifiers, the NetMax system has the ability to monitor the amplifier, speaker line and speaker through a sophisticated impedance monitoring protocol. 4 5 Comprehensive Control IRIS-Net provides the system designer with a comprehensive and easy-to-use interface to control any aspect of the NetMax N8000 digital matrix or RL amplifier. From assigning macros, setting schedules, running system checks or setting up channel equalization it can all be done from this one interface.

Several hardware options are available which enable the N8000 to perform a variety of complex tasks including automatic microphone mixing, extended DSP functions, etc, all the while maintaining full communication with other IRIS-Net equipped components. AI-1 / MI-1 The AI-1 is an eight-channel analog input module for the NetMax System Multimedia Presentation and training rooms typically feature multiple AV sources that need to be distributed to multiple sources individually or simultaneously. Integration of these different types of sources can be a challenge for an installer, but NetMax offers a unique solution to these challenges. In addition to signal processing and distribution, the N8000 offers Ethernet, RS-232, contact closure inputs, contact closure outputs and VCA inputs to allow a high level of integration possibilities with new or existing AV equipment ranging from a relay-driven projector or lighting sources to existing multimedia control systems. Controller. Audio signals are connected via screw lockable Euro block connectors. A-to-D conversion is handled by high performance linear 24-bit converters. Internally the signals are processed in 48-bit word length. The MI-1 is a Microphone Input Module for the NetMax System Controller. The module provides a variety of microphone input functions and extended mixing features to greatly enhance the power of the N8000 in numerous applications.
