dB Technologies AC26N
Digital Audio Controller for Loudspeaker Processing
The new audio digital processor AC26N allows you to control any professional audio system, both active and passive.
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 outputs possesses a parametric equalizer, delay, phase and level control, completely run by a powerful 28/56 Bit DSP, unique in its kind.
This processors control may be directed by the front control panel or through an RDNet connected computer.
