I am trying to simplify my setup while switching to DSP crossover with no analog input (minidsp flex).
I have a cheap ART DJ phono preamp with 9V brick and I am looking at this audophonics RCA to spdif board (5V in):
https://www.audiophonics.fr/fr/modu...1804-rca-vers-spdif-24bit-192khz-p-17047.html
Idea is to put these two boards in the same enclosure with a psu (240V in) with two output: 9V DC and 5V DC.
Signal wise: two RCA in from the turntable in the phono preamp, two RCA out to the ADC board and a SPDIF out to the minidsp as a "digital" source.
Two questions:
Thank you!

Two questions:
- is the proposed "lego" electronic build ok? Anything I should be looking for?
- how to build this PSU? Most smps don't have two outputs. Is there an easy way to do this?
Thank you!
Ideally, I'd go with electrically isolated linear power supplies to eliminate the possibility of ground loops. Hammond has some low-profile transformers with dual windings: https://www.hammfg.com/electronics/transformers/power/229
I'd want to take a look at the ART to determine what the real power supply requirements are. Maybe there's a linear regulator on board which could be bypassed.
