dBTechnologies AC26N Digital Audio Processor

The audio digital processor AC26N from dBTechnologies allows you to control any professional audio system, both active and passive.

Thanks to the quality of converters, the powerful processing and the compatibility with RDNet remote control protocol, the AC26N is an extremely versatile tool that allows you to manage in real-time active and passive systems or act as a matrix for loudspeaker system managing, solving tons of issues typical of live music applications.

Equipped with two inputs and six outputs balanced analogically, two in/out digital AES/EBU and an RDNet control, this processor allows a perfect control in a simple and complete way. Each output possesses a parametric equalizer, delay, phase and level control, completely run by a powerful 28/56 Bit DSP, unique in its kind.

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 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.
