Zone Systems Digital NMX-88

The NMX-88 is an audio matrix with a Digital Signal Processor (DSP) that offers a complete and versatile solution for handling and processing audio signals. With this matrix, sound systems can be configured with easy control for the end user. It has powerful audio signal processing tools to adjust and enhance the signal for any venue or application, achieving the best results for sound distribution. It provides the installer the ability to configure sound systems with multiple inputs and outputs, and gives 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 power (400 MIPS, 1600 MFLOPS).
It has 8 analog inputs and 8 analog outputs. Additionally, it has a USB sound card input and output channel for playback and recording on a PC or use with video call software.
One of the key features of the NMX-88 audio matrix is its signal processing algorithms. The main ones include: Echo Cancellation (AEC) for video conferences, Feedback Cancellation (AFC) allows for flexible placement of microphones and speakers, improving speech amplification and delivering audio where needed. Noise Suppression (ANS) effectively eliminates stationary noise that is different from voice. Automatic Gain Control (AGC) ensures that inputs have an optimal level. In addition to other functions like auto mixing and priority control, it also processes the dynamics of the signal with features like parametric filters, graphic filters, noise gate, expander, compressor, delays, crossover network, and limiter.
Each channel has a volume control that can operate independently or combine two channels to form a stereo channel.
The assignment matrix allows you to assign inputs to outputs with independent volume on each assignment. This allows you to select a different mix for each output.
Up to 16 scenes can be loaded, with a memory function that auto-saves the selected parameters from the last session.
8 GPIO ports for controlling actions on the matrix or other devices.
For conference system applications, it offers PTZ camera control for tracking the discussion.

 
The matrix comes with 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 parametrization. This provides 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 multiple matrices to form a complex system.
With the software, it is possible to create custom control panels to run on touchscreens, tablets, or smartphones (Android and iOS). It allows you to display only the necessary functions 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.
