ELectronics

On the fast track with the latest technology

 

The new Accuton DSP - board (DSP 192-4-111) is the first product of electronic aids  we want to offer those of our customers, who are constructing active speakers or want to upgrade their existing boxes with an option to activate.

The DSP receives analog and digital signals up to 24 bit / 192 kHz and can manage 2 x 2 channels for stereo  or 1 x 4 channels in mono operation. Multiple boards can be cascaded. Internally, the DSP works with 24-bit / 192 kHz and therefore it can manage time-delays of 1 sample = 1.78 mm, which is an acceptably small value for a high-end speaker and has not been achieved so far.

We offer an additional plug-in board, which allows to connect up to 3 DSP modules together. The number of channels can thus be extended to 1 x 12 (mono mode) or 2 x 6 (stereo mode). The plug-in board includes an S/PDIF input with loop-through function, an interface with master and slave function, and an input selection switch (digital / analog).

We will develop more components in this model range, such as amplifiers and radio Transmitters, that keep your products not only in terms of loudspeaker technology, but also in the digital domain to the latest state-of-the-art.
