The wiring looms require some thought as you don't really want to mix up the high current mains and speaker wiring with the sensitive small signal wiring ;)

Green lights mean all channels are go ! What do you do in lockdown whilst waiting for Ultimate-Preamp DSP boards to be manufactured by our production house ? Answer is to write an operating system for our multi-channel power amp. This time we are cutting code for an STM32 M3 ARM micro and not a SHARC DSP. So far everything is going to plan.

  • Power Amp Mains Sequencing tick !
  • Main-switch and trigger-IO monitoring and relaying   tick !
  • LED display driver tick !
  • Real-time Amplifier/clipping/DC error/Over-Temp-Alarm and general fault monitoring and display tick !
  • Thermal management in testing phase !

The custom all stainless steel case is earmarked for a customer who along with the still to be delivered Ultimate Preamp Plus (sorry for the delays) will be using it in a custom active speaker system of their own design. Using all Hypex NCore amplifier modules in a custom case that matches the Preamp we found the Hypex modules to be the ideal choice for this application with no shortage of power and performance.
