Raul is correct. I would just add that the wire going to the "ground" side of the RCA plug is the one that should be soldered to pin3. Pin 2 gets the "hot" wire. You can do it yourself, but since Tri is colleagial with Atma-sphere, I am sure he would do it for you, too. I own both a Triplanar and an MP1 myself. I think you will be very happy with that combination and the "right" phono cartridge. |
Convention for a balanced connection: Pin-1: shield (balanced signal ground) Pin-2: positive signal Pin-3: negative signal You have two options: 1. Run single ended into your balanced system as stated the posts above: Pin-1: jumper to Pin-3 (connect RCA ground to balanced ground) Pin-2: connect your positive RCA wire Pin-3: connect your negative RCA wire 2. Create a balanced connection. This has been the subject of heated discussion over the past 12 months. From your perspective, you could care less. I'd try to take this approach. Pin-1: find a tonearm chassis ground point and connect it to pin-1. Pin-2: connect to your positive RCA wire (as above) Pin-3: connect to your negative RCA wire (as above) Comments on running balanced on the Atma-Sphere site: http://www.atma-sphere.com/support/se.html Strictly speaking, Ralph mentions only line level sources in detail in the first paragraph - assuming your tonearm manufacturer will wire your tonearm cable for you. The same principles apply from a wiring perspective for a tonearm - save the discussion on whether or not a cartridge is balanced or floating single ended. For your purposes, you don't care. It's the sound you're after, so wire up in balanced mode and have at it. Cheers, Thom @ Galibier |
Dear Thom, I've been thinking that your scheme #1 for hookup is the way you'd do it if a cartridge really had a hot and ground side, i.e., the way to do it if you were to hookup a single-ended CD player to a balanced input preamp. Scheme #2 is the "only way to go", in my view. In fact, in my case I just hook up the tonearm cable shield to pin 1. This works fine with the MP1. |
