NAD M51 DAC high-pitched ringing?
Hey guys,
Not sure if I posted this in the right place, but I could use a little help.
Just setting up my new system and I've encountered a major problem: a high pitched ringing. Here's what I've got.
Macbook -> NAD M51 DAC-> Jolida 1501P amp -> Silver SR16 Speakers
Whenever audio is coming out of the computer, through the dac and amp, there's a loud high pitched ringing sound, like after you've been to a loud concert. The ringing comes in and out a bit, but is present about 95% of the time.
When no audio is playing from the computer (music is paused) there is no ringing. But unpause the music, the ringing starts and continues for about two seconds after the music is paused.
I don't think the sound-files are responsible.
So far, I've troubleshooted it and I've hit a dead end:
The DAC plugged into a different amp/speaker setup has no ringing.
When I connect my ipod or laptop directly to the amp: no ringing.
I've also tried using a Ray Samuels Audio Apache as a preamp with the NAD M51 and the Jolida, but there was still ringing.
Interestingly: The RSA preamp has a mute feature, and when the sound-file is playing but the preamp is muted, the music stops but the ringing continues. I don't know how this mute function works, but it does not affect the ringing while the song plays.
Also, if you turn the computer volume all the way down, but keep the song playing, the ringing continues. It does not get louder with an increase of volume on any device.
Other interconnects also don't make a difference, either. I don't think it's power interference, either, but I can't be sure. I've tried different outlets.
I'm definitely a novice and don't know much about the actual workings of DACs and Amps, but the fact that the ringing starts and stops with the music might indicate that the DAC is the problem, but I have no clue exactly how.
So it seems the DAC and the amp are functioning properly independently, but something screwy happens when they are used in conjunction. And the DAC is producing some signal doing its algorithmic thing that the Jolida is picking up on.
Any ideas you guys might have would be a great help. Would contacting these companies be at all useful? Seems like each product works fine individually and they might tell me to buzz off.
Thanks guys,
Charlie
