Hi all. I connected my AT-LP5x turntable (with built-in pre-amp) to my mu-so 2nd gen via RCA cables to 3.5mm jack. The sound is … ok. Lacks gain and is generally underwhelming. I got a Pro-ject phono box E and connected it to the turntable via rca, and to the mu-so via toslink optical cable. But it buzzed terribly! I added a grounding cable between the pro-ject box and the turntable, but it made zero difference -still a persistent low buzz.
Any advice on a better pre-amp solution to boost gain without buzz?
In the input settings of the app you can indicate, for analogue input, 3 input level options. Default is 2V IIRC, maybe try to set to 1V and see if with your first option that sounds better?
Odd that you would get a buzz with an optical connection. May be a ground issue that needs a ground connection to the muso. Have you tried it with an analog connection to the muso?
Agree that the buzz with optical cable is weird. I went straight analog first — rca fromTT to 3.5mm jack to Mu-So — and there was no buzz, just low volume.
How would I ground the Mu-So? There isn’t a grounding point on it.
The Mu-So floats the earth. Getting a buzz from using the optical input makes no sense to me unless it’s an earth issue within the AT-LP5x that’s then being converted to digital along with the music signal.
