Mini-DIN pinout on ATP3 amplifier PCBīecause I can’t find the male of 7pin mini-DIN connector on local market, so I remove the connector and I soldered rainbow cable directly on the PCB. I found the functions of the pins as follow:įigure 1. Googling this yields some information about the pins but it didn’t solve the problem because nobody posted about the pins functions. Since the connection from amplifier circuit to right satellite speaker use 7pin mini-DIN connector, I try to search about ATP3’s mini-DIN pinout. For tone control, ATP3 use IC LM1035 from National semiconductor which use DC controlled bass, treble and volume technology.īut I have problem because all speaker control is on ATP3’s right satellite speakers. ATP3 configured the IC to work both in single ended and bridge, 2 channel in single ended configuration for powering satellite speakers and 1 bridge configuration for powering the subwoofer. This amplifier IC can be configured to work either in dual bridge or quad single ended amplifier. The heart of this amplifier is quad power amplifier TDA7337 integrated circuit (IC) from SGS-Thomson. Volume, bass, treble control and right speaker is connected to amplifier using 7pin mini-DIN connector.

Left satellite speaker is connected to amplifier using RCA connector. Input signal is connected to amplifier using 3.5mm stereo connector. I opened up the ATP3 subwoofer and found that amplifier circuit is located inside subwoofer enclosure. ape (MonkeyÃ¢â‚¬â„¢s Audio).ġ.Harman kardon soundsticks 2 (hate the way it looks)ģ.Razer Mako 2.In this project, I want to replace ATP3’s original satellite speakers with my Selenium surround speakers. I DO NOT use mp3, its mostly FLAC and at times. although Alternative Rock is kinda sweet spot. I listen all kinda music, i even have backstreet boys. My room is abt 16* 14 feet, i can only buy a 2.1 system, i hate anything higher than this bcuz i hate wires, so pls dont suggest anything apart from 2.1.īudget is not a issue for me now, having said that i do look for value and try to keep it under 30k. PCs came, PCs gone during these 9 years actually the one i`m using right now is the 4th desktop, apart from countless upgrades tht keep happening time to time. They are truly legends for me, i got these beauties in the summer of 1999, yeah it been 9 years, and i still love them. Finally i wanna lay my Altec lansing ATP3 to rest.
