Zone Systems Digital NMX-88D

The NMX-88D is an audio matrix with a digital signal processor (DSP) that offers a complete and versatile solution for audio signal management and processing. With this matrix, sound systems can be configured with simple control for the end user. It features powerful audio signal processing tools to adapt and enhance the signal to any venue or application, and obtain the best results for sound distribution. It gives the installer the possibility of configuring sound systems with multiple inputs and outputs. And the user an easy way to control the sound.

It is based on an ADI SHARC 21489 architecture, with 40-bit floating point and high processing capacity (400 MIPS, 1600 MFLOPS).
It has 8 analog inputs and 8 analog outputs and 8 digital DANTE inputs and 8 digital DANTE outputs. In addition, it has a USB sound card input and output channel for playback and recording on the PC or for use with video call software.

One of the standout features of the NMX-88D audio matrix is its signal processing algorithms. The main ones include: Echo Cancellation (AEC) for video conferencing. Feedback Cancellation (AFC) allows flexible placement of microphones and speakers, improving speech amplification and delivering audio where it is needed. Noise Suppression (ANS) effectively eliminates stationary noise other than voice. Automatic Gain Control (AGC) ensures that the inputs have an optimal level. In addition to other functions such as auto-mixing and priority control, it also has processing on signal dynamics such as parametric filters, graphic filters, noise gate, expander, compressor, delays, crossover network, and limiter.
Processing can be applied to both analog channels and DANTE digital channels.
Each channel has a volume control that can operate independently or link two channels to form a stereo channel.
The assignment matrix allows inputs to be assigned to outputs with independent volume in each assignment, making it possible to select a different mix for each output.
Up to 16 scenes that can be loaded and a memory function with auto-save of the parameters selected in the last session.
8 GPIO ports for controlling actions on the matrix or other devices.
For conference system applications, it has PTZ camera control for debate tracking.

 
The matrix features powerful modular configuration software. You can configure each input channel with 5 different processing modules and each output channel with 4 processing modules. The processing algorithms have extensive parameterization. It enables great flexibility in configuration and customization to provide a solution for each installation, such as audio distribution, conference systems, etc. The configuration software can manage several matrices to form a complex system.
With the software it is possible to create customized control panels to run on touch screens, tablets or smartphones (Android and iOS), where it is possible to display exclusively the functions needed for each user.
The matrix can be connected via an Ethernet port. It has UDP, RS-232 and RS-485 connectivity, and a communication protocol for integration with other control systems.

Thanks to its flexibility it can be used for voice applications such as conference systems or video call rooms and in music systems in restaurants, hotels, shopping centers, etc.
