我把MD2的立体声引出来了,但接到耳机上发现有一定的电流声.接到音箱上,在静音下也能听到电流声.想把MD2的声音打磨一下.请问从哪里下手啊?
我把MD2上面的电解电容都换成音响用的了.还是没觉得有改善.

很奇怪,好象和游戏有关. 插街霸2(原装的牛屎版)是轻微的沙沙声音,插其它游戏就是类似的电流声.
对了,MD1的耳机输出也是这样.只是MD1耳机接到音箱上这种底躁音要比MD2小点.

和电源无关吧?偶的电源都是原配SEGA的直流. 交流110V变压器是公牛的60W.

哇,太华丽了.好复杂啊.这外国网友怎么不拿一块版子做啊.

顺藤摸瓜找到全图的.

form my personal tests, I've found that Nomad sucks, MD2 sucks when its unmodded and early MD1 wins unmodded. I don't know about later MD1s, they have shittier sound, but that sound should still be better than anything else besides early units. The one thing MD2 fails at is high freqs, and same for Nomad, I haven o idea where did that guy heard them... MD2 is clear winner when you have modded one, no noise to speak of and all freq range is unaltered. Also MD2 features more higher quality audio chip implementation than MD1 does. I'm going to work out a Nomad audio mod too sometime (when I get few Nomads). It is pretty much MD2 with a screen, and has integrated YM2612 which is most likely the better kind one... its just that all analog parts related to audio in MD suck in their original form.

这段话有人翻译一下吗?好像说MD2采用的音频芯片要比MD1好一点?

主要是底噪音问题,而不是音源特色问题.
改天弄台SFC测试一下底噪大不大...

那个老外网上说SEGA有一批MD1的耳机输出音色特别纯净,而且几乎没底噪.不知道是哪批...
