Triplanar RCA out to Balanced out for MP-1


Hello all, especially Doug Deacon

Well,,,,,, my Atma-Sphere MP-1 mklll has just arrived. much joy. Now I need to reterminate my RCA out from the Triplanar to a balanced out.

I am a competent solderer.

All suggestions and hints welcome

I have a seperate ground wire coming from this box. It could have been spliced to offer two length's?, I think.

This is a moot point since I have now spoken with Mr. Mai, and he will gladly do the mod for a minor fee.
Cousinbilly, I gather your Triplanar has the optional external junction box with the standard female RCA receptacles. This allows you (or forces you) to use additional phono cables from the junction box to the preamp. Since you have decided to send it back to Tri, I encourage you to consider having him remove the junction box in favor of cables that go directly from the cartridge to your preamp inputs. Said cables would be terminated with male XLR connectors, of course. I think this is advantageous with low output phono cartridges, the likes of which you will be using.
Hello Lewm, I had to read your post twice. I have the newest version of the Tri. After the junction box, we now have two shielded cables coming out. Each one is fitted with the Male RCA. I realise there may have been a time when seperate cables where needed. This is no longer the case. The tonearm connects directly to the pre or phono pre (while I was using the Tom evans groove). No extra cables needed.

I have reread the previous posts. I now see why there where a few different ideas. Some people did not realise the cable is already terminated with male.

The installation of balanced cable ends would not be difficult at all. The only dilema I am faced with is I have no shrink wrap. This makes the installation look less professional.
Triplanars come in two basic terminations:

1. Hardwired from cartrdige lead to connectors (either RCA or XLR).

In this configuration about 2.5 feet of cable runs inside a single braided sheath between the tonearm and a small rectangular box. This sheath carries both channels. The other side of the box feeds two braided cables - one for each channel, terminated in either RCA's or XLR's.

The question I was addressing is what's inside of this box - is there access to the tonearm's chassis ground.

As I mentioned earlier, any wire that connects you to the tonearm's metal components will do (for a pin-1 connection), but it's obviously preferable for there to be a cable shield which is tied to the tonearm - to run this to pin-1.

2. Hardwired from cartridge lead to a junction box with female RCA's - requiring an extra set of interconnects to run to your phono stage. This is *not* recommended because (a) you have an extra connection which degrades the sound, and (b) the Discoverey Cable Tri uses is outstanding.

Cheers,
