Title: Grounding ZP3 and ZMC Post by Kirk on 02/05/24 at 20:10:05 How should the grounding lugs be used on ZP3 and ZMC? Should those lugs be connected to my home's main ground? I am about to rewire my Rega Planar 3 and the kit will add an external ground. Should the TT external ground connect to the ZMC? I do not use the power cord on the ZMC. |
Title: Re: Grounding ZP3 and ZMC Post by Sean on 02/05/24 at 21:42:39 I don’t have a ZMC, but I use a Cinemag SUT. I run the ground from the TT to the SUT and another from the SUT to ZP3. I have tried removing the ground between the ZP3 and SUT and get a hum. On other phono pre’s you can eliminate the SUT to phono pre ground to lower hum, I believe Steve mentioned the ZP3 needs ground to the SUT n the papers, but I haven’t read them in awhile. If you get hum, I’ve read wrapping the ground around the RCA’s can help. Made no difference for me. My system does hum, I didn’t think it did until I turned the whole house fan off. I don’t notice hum during playback, just with my ear in front of speakers. |
Title: Re: Grounding ZP3 and ZMC Post by Kirk on 02/08/24 at 23:40:35 Thanks Sean. I rewired my Rega tonearm so I now have an external ground (and better cabling and RCA connects). External ground is connected to the SUT and SUT's ground is connected to the ZP3. Sounds terrific. I no longer get a snap in the speakers when I touch the tonearm (static electricity discharge). |
