Amp interface

 

The amplifiers are also made by myself. In the original design by Elektor there was no option for an Ir-remote. Connecting the amplifier’s and other audio related equipment to the Joshua bus , controlling is now possible with everything available on the bus.
The preamp was working with logic levels +9V and -9V, this made the interfacing a little bit complicated and extended.
