Hello,
I have a technical question to my Movie / Music Setup, I use the following setup:
Polk ES60 Speakers --> Pro-Ject DS2 Amp Box --> Pro-Ject Pre Box DS2 Analogue --> Fix Line Out (RCA) --> for Music Wiim Ultra (RCA) / for Movies Marantz Cinema 70s Preout Fronts (RCA)
The System works great, but I get a really annoying Buzz / Humm from my Polk ES60 Speakers if I use them with the Marantz Cinema 70s PreOut as Frontspeakers. If I use the Wiim Ultra, there is no buzz or humm noticeable.
I tried different Line Inputs from the Pro-Ject DS2 Pre Analogue, but the buzz / humm would be the same. I tried different PreOut Input of the Marantz, still the same. If I disconnect the RCA from the Marantz Cinema 70s and leave the signal chain on, then the buzz / humm stays the same.
Does someone has a suggestion how I can solve the problem or another idea what I can try?
The Pro-Ject DS2 Amp Box has an Inputsensitivity of 550mVrms, maybe it is too low for the Marantz Cinema 70s Inputs? In the Wiim App I changed the Line Out Level (mVrms) to 500. Is there an Option for the Marantz Cinema 70s ?
Sorry for my bad english,
