Prefix connection

Mick
Mine is
Prefix to socket 4
socket 2
to preamp

Bob

the prefix's 5 pin din goes into hicap socket 4 (its the only socket on the hicap it can go into). then you need either (a) a 4 pin din to 2xBNC cable to connect from hicap socket 3 to the BNC inputs on your 52 (MAKE SURE THERE ARE NO PHONO CARDS IN THE 52!!!!) or (b) a 4 pin din to 5 pin din cable to connect from hicap socket 3 to any available 5 pin din socket on your preamp. READ the 52 manual on the dual purpose of input 2 (2a and 2b) on the 52 and follow the instructions carefully.

good luck...

Mick, You will be happy about the improvment.

Thanks for the advice but I appear to be lacking the correct interconnect between the Hicap and 52.

Mick

I'm not sure it would always be the same socket from the HiCap to the 52 - it depends on vintage.

Naim would always recommend feeding a Prefix into a DIN socket input on the 52.

Erik,

some prefer the Prefix powered directly from the 52.

i am sure you can get the appropriate cable from your dealer or from naim direct.

are you going for bnc's or din on the 52?

That is how I currently have it connected.

"Some prefer the Prefix powered directly from the 52"

That'll be Dev then.

I ran my Prefix from a Hicap (Supercap is better) and much preferred it to 52 power.

With a 552, on-board power is superior to the Hicap. Not tried Supercap vs 552 but Herman on the M*n* forum has and prefers the 552 powered Prefix

Hi Bosh & Mick,

This is personal preference, but I do prefer the Prefix straight into the 52.

Compared to the Hicap it is not as "refined" sounding but it really has superior PRAT and more of a upfront presentation. In my large room this is better as the sound projects out of speakers more.

The Hicap Prefix is more refined and smoothes over HF (i.e makes it more extended and sweeter) but it is slower and doesn't PRAT as well. If you have a very refined cartridge the straight into 52 option is better, but if you have the choice you can A/B and decide.

All of this is just my preferences though (...and I think a CDS2/XPS2 is even better in the PRAT/Musical dept that my LP12...)

regards

Dev

If you are being experimental - how about trying cross dressing?

Mick.....the cable to connect the HiCap to the 52 should have been supplied with the Prefix when purchased. If it wasn`t, go back to whoever sold it to you and ask them to supply it....you should not have to pay extra for this

Dev,

have you had your Prefix updated with the RF mod?

Some time ago I compared Stageline S to my Stageline K (with DV TeKaitora). The S was a lot better, the instruments just gelled together and music made a lot more sense.

I put this down to correct loading of the cartridge, but since then I have made some RF mods to my amps, specifically removing the paint around the RF bolts on my olive kit, and a similar change to my 135s. These brought big gains in cleanness, speed and control, and I now believe that the main improvement of the 'S' boards were to reduce RF in my LP replay.

Before I made the RF mods on the amps, the LP12 was a lot better than the CDS2. Tables are currently turned, something I'm sure the new low-RF prefix would fix.

cheers, Martin

P.S. let's hope this posts OK this time!

There is a cable from the prefix which goes into the 52. Should there be another ?

Dev

I think I will give your suggestion a miss (pun intended)

you use that cable if you want to power the prefix from the 52. but from your initial message this is NOT what you wanted to do. you wanted to power the prefix independently of the 52, in which case, as i said in my first response to you -- YES, you need another cable to connect the prefix's *cap to either DIN or BNC's. and sa i said, your dealer should be able to supply that cable to you. have you asked your dealer yet?

enjoy

Mick..the cable from the prefix to the 52 (input 2b-I think) carries power from the 52 (scap) to the prefix, and signal from the prefix to the 52. This cable is captive to the prefix. When you use a hicap, this captive cable plugs into the hicap. You then need a another cable (snaic) between the hicap and the 52. This second (non-captive) snaic should indeed be supplied as part of the prefix package when purchased, and is not an "extra" item

Hope this clarifies

Laurie,

actually, it's an interconnect.

Martin is quite correct. If you are using the Prefix with a dedicated power supply then to take the signal from the power supply to the preamp you will require a 4-5pin DIN Interconnect.

Richard

I thought that S.N.A.I.C. was an acronym for:
Super-Naim-Audio-Inter-Connect?????

(So...is a SNAIC not an INTERCONNECT?)

I`m guessing here...Naim reserve the term "SNAIC" for "cables" that carry signal AND power.... cables that carry signal ONLY are thus referred to as "interconnects"

Whatever you call it....you need one and it should have been supplied with the prefix

Laurie,

yes, you have it.

The major constructional difference is that the SNAICs are shielded, and the interconnects are not.

Whilst Richard is contributing to this thread, can he confirm if a 4-5pin DIN interconnect is supplied with a Prefix?

cheers, Martin

It is.

The prefix when used with a power supply needs a 4 pin 240 degree to 5 pin 180 degree lead. That is what we supply.

From Naim (20.08.2001) Hope this helps

Hermann

Hi Martin,

yes, the Prefix comes packed with a 4-5 pin DIN Interconnect as standard.

Richard

p.s Thanks Hermann, just noticed your reply.

I have just found the 4/5 pin interconnect tucked away in a cupboard, so I will wire it up on Saturday.

Thanks for all your help.

Regards

Mick

I connected up the Hicap this morning and it sounds considerably better than just plugging it directly into the 52.

I will do the same experiment with the Supercap2 when it arrives next week and then go for either one or the other. The TT was sounding brilliant with the Hicap.

Regards

Mick
