Hi Virus:

They are connected properly.

I've also tried setting the left to "Master" and let it have SPDIF signal directly. The screen will display "PCM 44K" but no sound. (So this should eliminate the Comm cable problem) But thanks for the suggestion. I really wanna exam all possible scenario.

This problem is very bizarre. I called Meridian UK a few times and they said never encounter such problem.

If the screen can display PCM 44k it means there is incoming signal

Also if the speaker still produce the hiss sound it means the power amp is working.

They think it's interconnecting problem, but I opened once and did not find anything wrong.

It was yesterday I asked a friend who is electronic expert. When he was here my speaker started working fine... So at the end we did nothing, just sit down and enjoy the music.

Is it possible that the DSP computer need running in? (before it can produce sound.. = =)...

Current System: Toshiba SD-9200 --> DSP-8000
Secondary System: Pioneer DV969 --> DSP-5200
