Has been a long time to finish this 2.1 active crossover amplifier project.
The projects idea started 2017 by designing a 2.1 linkwitz riley 24dB analog crossover pcb.
Hypex components used in this amp:
1 x SMPS400A180
2 x UCD180 HxR
1 x UCD180
Modushop.biz:
1 x Slim Line 01/280 10mm BLACK front panel - 3mm aluminium covers - Rear panel: Without IEC hole. Typ: 1NSLA01280N
Own components used in this amp:
1 x +/-15V powersupply for the analog crossover - +/-21V derived from SMPS400A180
1 x analog crossover pcb
1 x sa2022 grounding pcb
1 x 5V power supply with 230V/16A relay - prepared for MCU control
The crossover frequency is tuned to 80Hz. The 2 basschannels are mixed down to a mono subwoofer signal.
The 1 HE sized case has been diy machined and diy engraved at home using a grblHAL style diy CNC machine.
A perfect combination to drive my outdoor 2.1 system (2x Polk audio Atrium 8 SDI and one Atrium SUB100)
Have fun,
Toni

Hello, good morning
I have to say that I have no knowledge of electronics, but I'm very good at DIY, and I'm learning something this way.
Although this post is old, it's exactly what I was looking for, and I haven't found it yet.
I wanted to know if you have the boards for these components for sale, since I'd like to build the amplifier:
1 x +/-15V power supply for the analog crossover
1 x analog crossover PCB
1 x SA2022 grounding PCB
1 x 5V power supply with 230V/16A relay - prepared for MCU control
If you don't have the boards, could you sell me the files? I'll have them manufactured myself, as well as the front and back panels of the box.
I also ask, what are the trimpots on the crossover output for?
Thank you very much.
Best regards.
