Hej guys,
Long over due but here is a sneak peak of how we're prototyping the ReCreate project. We had a pair of old RL45.2 in the office that we thought needed some love. As our HW proposal is still under development we are using HifiBerry Amplifiers combined with Raspberry Pis to benchmark current performance on the market and investigate the open-source offering that exists in the community today.
I started by opening up the RL45.2, the driver might need a refoam soon but good enough for now. I cut the crossover and installed the wires in the correct ports in the Hifiberry AMP.
Close Up of the Raspberry PI + Hifiberry
The Raspberry Pi is running a Raspbian OS configured for the Hifiberry with Shaiport-Sync setup. In order to get the crossover implemented I coded the ALSA (Advanced Linux Sound Architecture) configuration files using LADSPA plugins following
In the end the RL45.2 looks original and sounds decent. Can't wait to try it with one of our amplifier boards instead (twice the power!) as this sounds a little weak which is probably due to the low power output of the current Hifiberry Amp+ (2x25W). But to be honest if I can figure out how to fine tune the ALSA settings I can probably push some more juice out of it.
Do you guys have any comments? Would you be interested in creating a similar project? Thanks for reading and I'll be posting more projects here within the next days (yes now insert an appropriate joke about it will take years...)
Cheers!
