 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

12V barrel jack power and the output seems pretty immune from noise on the supply. Quoted as 15W per channel. Take that with a pinch of salt but still plenty of oomph with no obvious distortion. 3.5mm stereo jack input and screw terminals for the speakers. Works like a treat on the pico using volhout's magic filter.  This is the module and here is the stl for the box 52mm x 48mm x 30mm ampbox.zip Edited 2024-11-02 22:43 by matherp |

Extortionate price, of course. :) Your ears will love you if you stick to a maximum of 8W per channel into 8Ω with a 12V supply, giving 0.1% THD. That is soddin' loud in the average living room though. :) Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

Look at AliExpress for even cheaper prices. Already seen under 3 Euro including shipping costs. Has excellent specifications. Power at 12V DC 5W 8Ω --> THD+N=0.1% 8W 8Ω --> THD+N=1.0% 10W 8Ω --> THD+N=10% 15W 4Ω --> THD+N=0.1% Efficiency: >90% It says here that it is a 2x10W with this configuration and if a larger heat sink is used, 2x15W. Also nice to use the extra connections such as mute and the power switch. Jan. |
