Electro-Voice DO-1 Digital Output Module for N8000 System Controller

The Electro-Voice NetMax N8000 is an all-purpose digital audio system controller with outstanding performance features. A high-quality system design provides excellent audio quality and clear sound, which is achieved by the application of high-end 24 Bit A/D and D/A converters with 120 dB volume range, high-quality input and output circuits in the analog domain and digital signal processing with optimized 48 bit double-precision algorithms. Hence, the N8000 is even particularly suitable for demanding applications in theatres, concert halls, big churches etc. NetMax N8000 is highly flexible due to the modular hardware design, which renders many other applications possible. Four slots with 8-channel audio modules at the rear of the device offer up to 32 local audio channels. Each slot can be equipped either with an audio input module or an audio output module. So, various configurations (e.g., 8-in/8-out, 8-in/16-out, 8- in/24-out, 16-in/ 16-out, 24-in/8-out) can be realized in only one single device. In addition, N8000 can be equipped with a CobraNet or Dante network module.

Several N8000 units can be integrated in a network and be connected to a large, sophisticated system. The signal processing in the N8000 is affected on powerful audio signal processors where, depending on the stage of expansion, – up to 8 DSPs are available. The software contains a multitude of freely programmable signal processing components. Among other things, these are filters with all possible characteristics, parametric and graphic equalizer, matrix router and matrix mixer, delays, dynamic functions, etc. Diverse configurations can be created by combining and connecting these DSP blocks.

The powerful signal processing allows complex configurations for the adjustment and control of the sound system, depending on the application or type of event. Thus, the sonic quality of PA speakers, monitor speakers, front fill systems as well as of the sound reinforcement of adjoining rooms, lobbies, areas for the staff etc. can be optimized and tuned individually. In other words, the N8000 copes with every application – even with large and complex systems absolutely exactly and reliably. In addition to the audio processing, the NetMax N8000 is equipped with diverse control functions. The scheduling with calendar function makes it possible to program one-time or recurring events. The recurrence can occur annually, monthly, weekly, daily, hourly or even within smaller time intervals. Furthermore, daily programs can be set up and can also be combined to weekly operations. With the event control, reactions to certain events or system states can be configured, e.g., in case of overstepping or undershooting of threshold values. 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. Furthermore, it can be defined which types of errors or events should be recorded. The log can be read out and displayed on the screen at any time. In the NetMax N8000 individual functions can be integrated into complex operations. For example, several parameters can be set with various values or states in a scene and can be changed manually or automatically at any time.
