Fonestar NMX-88 Audio Matrix

Description

Fonestar NMX-88 8×8 audio matrix with DSP

8 x 8 audio matrix with DSP and 8 GPIO. 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 simple end-user control. It has powerful audio signal processing tools to match and enhance the signal to any venue or application, and get the best results for sound diffusion. It gives the installer the possibility 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 floating point bits and a high processing power (400 MIPS, 1600 MFLOPS). It has 8 analogue inputs and 8 analogue outputs. In addition, it features a USB sound card input and output channel for PC playback and recording or use with video calling software. One of the outstanding 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 flexible placement of microphones and speakers, improving speech amplification and delivering audio where it is needed. Noise Suppression (ANS) effectively eliminates static noise other than speech. Automatic Gain Control (AGC) ensures that the inputs have an optimal level. In addition to other functions such as auto mix and priority control, it also has processing on signal dynamics such as parametric filters, graphic filters, noise gate, expander, compressor, delays, crossover and limiter. Each channel has a volume control that can operate independently or link two channels together to form a stereo channel. The assignment matrix allows inputs to be assigned to outputs with independent volume on each assignment. Achieving to select a different mix for each output. Up to 16 scenes that can be loaded and memory function with auto-save of the parameters selected in the last session. 8 GPIO ports to control actions on the matrix or other devices. For conference system applications, PTZ camera control is available for discussion monitoring. The matrix is equipped 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 are highly parameterised. It allows for great flexibility in configuration and customisation 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 customised control panels to run on touch screens, tablets or smartphones (Android and iOS). Where only the functions required for each user can be displayed. 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 centres, etc.
