Modular Hardware Concept

Using pre-developed hardware modules, we are able to rapidly develop new projects. Core components for this are (among others)

  • a pluggable core module with MCU and Sharc DSP
  • dual range ADCs with incredibly high dynamic range (138 dB)
  • several DACs
  • IC-based multi-channel power amp modules (e.g. 8 x 50W) with digital signal input and small dimensions
  • bus boards for connecting power amp modules of several vendors
  • Dante Brooklyn / Ultimo boards
  • an F-LINK interface to connect multiple DSPs incl. auto detection for column speakers or line arrays, e.g.
