I’ve set up my Port to play line-in output through to a One-SL pair in a different room. I want to be able to select between two sources for that - turntable or CDplayer.
I’ve done this by connecting my Port to an analogue (Marantz PM5005) amplifier. I’ve connected the Port’s line-in RCAs to the amplifier’s Recorder-out RCA ports. My turntable (Pro-ject Essential III) is connected to the Phono-in RCAs in the amplifier (i.e.there’s a built-in pre-amp in the amplifier). I also have a (Marantz) CD player connected to my amplifier via CD-in RCAs.
Both CDs and vinyl sound great on my analogue wired speakers.
To get digital output on my One-SLs in another room I select line-in input on my Sonos App. I play vinyl by selecting Phono on the analogue amplifier. This all works perfectly. However, when i select CD on the analogue amp, the sound through the One-SLs is hugely distorted.
Does anyone have any idea why this happens? The phono signal has gone through pre-amp so the signal power shouldn’t be that different. Maybe I need attenuators for the CD-in cables? The other factor is that I don’t want to lose the ability to listen to CDs in analogue mode so I need any solution to keep this possibility.
Just to say too that I previously tried a different approach, using the headphone jack as output source by connecting through a jack to RCA line-in for the port, but this produced distorted sound for both turntable and CD player. I’ve also tried plugging the CD player RCAs directly into the Port – I still get the distortion so it seems like the problem is more likely to do with CD player/Port compatibility than anything amplifier-specific.
All ideas/thoughts much appreciated.
