Amp to turntable

Postby Docoe » 12 Dec 2017 23:32

Hey folks,

Sorry if this is the wrong forum, I'm new here (and to turntables in general).

I've recently bought a Pioneer PL-112D turntable, and wish to hook it up to a Philips 702 tuner amp. The problem I have is the Pioneer has an output which is RCA wires (it has the red and white plugs, with a ground wire too).

Meanwhile, the Philips 702 tuner amp takes a 5 pin input, rather than RCA.

So I need an adapter with female RCA and male 5-pin. I've searched around, but I cannot find any that also take the ground part into consideration, which would leave it disconnected upon use. I've heard that having ground disconnected can create a hum.

Any advice, or can you point me in the direction of the adapter I need?

Many thanks.
Docoe

Yeah you just need a (female) RCA to a 5 pin (male) DIN adapter which are readily available on E-bay from many dealers.

So I don't have to worry about the ground cable which won't be connected?

Hello Docoe, welcome to vinylengine.

I think you're looking for an adapter like this:

That looks almost right, but then I'd have two of the U shaped earth parts not connected, which doesn't solve that issue.

Sorry if I explained this poorly in the initial post, I'm not used to talking about technology.

It would be possible to connect the both u shaped connectors by a screw, a nut and some washers.

Excellent idea. You could also clamp the two together with some sort of clip.

I once made one of these myself, I used a so called 'alligator' clip. It can 'grab' the spade of the turntable.

I have a soldering iron. Could I solder then together and just cover the metal with some electrical tape?

Well, you could solder them together, but it's really not necessary. It is only a ground wire.

You could just connect them with a small screw and nut as suggested.

This gives a secure connection that can be easily disconnected if needed, for whatever reason... and nothing has to be cut or modified.

Alternately, if you want to get fancy.......
Get a female spade connector that will accept the "U" connector from your TT and install it on the adapter.... in place of its "U" connector. :)

Hi,
the chassis ground is carried on the metal casing part of the DIN plug/socket - as opposed to the signal grounds which are carried on pin 2 (left and right together). The DIN cable will have, signal and signal ground wires, wrapped inside a braided shielding, it's this shielding that is connected to the 'metal casing' and carries the ground connection. This is why an amp fitted with 'din' connectors, may not have a ground terminal fitted.
The metal shell protrudes slightly proud of the pins, one benefit of this, over RCA connectors, is if you should connect/disconnect equipment with the amp switched on the ground connects first, avoiding the nasty buzz. Still not 'best practice' though.
You could connect your decks earth lead to the 'metal casing (shell)' of an adaptor, but as stated/shown in previous replies, if you can get one with the 'ground wire' fitted then it's a much simpler answer - din plugs are fiddly little things and soldering them is, for me at least, a last resort these days.
