Description

Overview:

The new audio digital processor AC26N has been designed for fixed and touring
installations, and allows you to control any professional audio system.
Thanks to the quality of converters, the powerful processing and the compatibility with RDNet remote control protocol, the AC26N isan extremely versatile tool that allows you to manage in real-time active and passive systems or act as a matrix for a loudspeaker system managing, solving tons of issues typical of live
music applications. It uses the most modern technology with 28/56 bit processors and high performance 24 bits 96 kHz AD/DA converters.The functions available are: input and output levels, delay, polarity, 12 equalization bands for each input and output channel, multiple crossover and high performance limiter/compressor.The control resolution of the filters is 1Hz.
Inputs and outputs can be set according to many configurations to meet any need. AC26N can be controlled in real time and all its parameters can be edited on its front panel or through a computer, thanks to the intuitive graphic interface of the DVA Network software and a dedicated RDNet or USB network
connection. The CPU and DSP software update, via PC, allows to keep the device up to date.It is possible to save and recall 32 preset configurations.
The AC26N can be remotely controlled using a pc-based software.Communication can be preformed using USB cable or connecting the AC26N into complex RDNet networks via Control 2 or Control 8 RDNet Hub.
This proprietary communication protocol has been developed for receiving and sending data.This connection allows real-time monitoring of loudspeaker parameters, such as output power,amp temperature, limiter status, etc…It is also possible to select different equalizations or create new ones, set the desired volume levels using the specific plug-in.
