Hi All,
Having trouble with my Marantz CD-400B demodulator. Two big issues.
1. Loud buzz occurs when in direct out two channel mode. I’ve tried daisy chaining the turntable ground from cd-400 to receiver with no luck. Also, when Cd-400 is not hooked up, and the turntable and receiver are hooked up to each other alone I have no grounding or buzzing issues.
2. When playing a Cd-4 record in 4CH mode, the radar button does not light up and it sounds more like it’s just playing double standard stereo between the four speakers. My cartridge is a relatively new AT-VM95ML.
I’m almost 100% positive I have it all hooked up correctly and I think it’s the unit alone. Without it in the system my turntable (Marantz 6200) and reciever (Marantz 4270) worked perfectly when paired only with each other. I’m using brand new RCA cables when trying to use the CD-400B.
Im not very skilled at working on this old equipment in general but if there is someone I could ship this to for repair or if anyone knows of someone in the Chicagoland that could help I would appreciate it. Thanks!
