Very nice sounding amplituner. Radio stations receive very nicely. Strong bass, top range not intrusive, great midrange. The announcer has a pleasant natural voice color. There is a loud, large power reserve, low distortion.

re: 3900Z

Anyone know how to hook up an antenna on the 3900z? I don’t have an owners manual.

re: 3900Z

I bought a used 3900Z a few years ago. I used it for a short time then gave it to my girlfriend along with a Hiachi PS-48 turntable and a pair of Advent 3 bookshelf speakers.
I have a 8900Z, Technics sl-1200mk2 and large Advent 4 speakers. I like her system more than mine. Maybe it's because the room size effecting sound. But even when I had the 3900Z I really enjoyed it. The tuner was great.
Her receiver is working but when powered on it seems glitchy....it's was like that when I bought it. Maybe it's normal? My 8900Z suddenly ceased after one day one channel was acting weird. Then nothing, no sound anywhere, both channels toast.

re: Sansui 3900Z

Dear all:

i acquire this Digital Synthesizer, with a little problem.
When i turn up the volume, in a speaker i hear a noise like distortion, but in the other speaker not hear that noise. Interchange the speaker but is the same problem in the same side. I think that i have a problem in the output channel.
Is possible that you help me with this problem.
I know a little of electronics, but i dont understand the service manual.
Regards and thank you.
