My dad just produced a stax sr-3 and srd-5, it looks to be in good condition but I'd like to hear it and the L and R speaker inputs have this strange plug on them.

Does anyone know if the female equivalent is still sold or the name of this peculiar plug ?

I'm thinking of making an adapter cable and trying to feeding the srd-5 from my beta22's XLR outputs (once it returns from repair).

thanks for any help

Just cut it off, go bare wire or solder an XLR jack on. I see absolutely no compelling reason to keep those.

Hmmm. First thought was some weird insulated banana, but then I noticed 2 conductors each. These aren't some strange RCA plug variant are they? I can't tell from your pic, but do these have a sleeve like an RCA inside the insulation of that plug?

They are old/vintage speaker plugs.

Bang & Olufsen B&O S-75 Burned Speaker Crossovers

thanks for that

given the price of the female plugs I'll probably re-terminate with neutrik xlr's instead and give it a listen

it'll be my first time I've heard a stax.

Whats funny is that in the late 1970's B&O produced speakers that needed

at least 100 watts to drive properly, and those were the connectors on the

end of a 16 gauge cable.

2 pin speaker DIN is how I've heard those referred to. hey still get used over this side of the pond, mostly in car audio I think.

thanks duggeh

searching for 2 pin DIN is a goldmine, I'll think about my options but at

Yeah, but so does Maggie Smith, so...

Cheap and readily available

Presumably these are the plugs attached to the ends of the left and right speaker outputs from the SRD-5. They are of no use unless you want to connect those outputs to a speaker with the equivalent female terminals, and as these are nearly unheard of, I would suggest removing the connectors. The inputs (from the amplifier) should be bare screw down terminals also at the back of the unit from memory. You should run your amp output to the bare screw terminal inputs of the SRD-5 and the cabled outputs on the unit to the speakers + and - terminals. The speaker/headphone switch will then work correctly.

Polk used to use those on their SDA speakers, for the cable that places one driver from each array into the opposing cabinet.

Also have seen them on really old car radio speaker cables. Pretty unusual for sure.

I think you're right .

I was right and am right.

They'd be connected to the amp level input wires as these were used quite broadly on cheaper electronics in europe in the 70s and 80s. Also because that Stax box has spring terminal connection sockets for the speaker output iirc.

Not unusual per se. Just obsolete. Everybody just switched over to banana plugs.

nothing new here, I'll decide whether to make an adapter once I know my amp is on its way back.

I was incorrect - the coloured wires, because they are so short, have to be connected to the back of an amplifier. The other terminals are for the speaker cables to connect to. Sorry about the senior moment. To repeat (correctly) for a normal amp with speaker cable screw down terminals, the coloured wires connect to the speaker terminals at the back of the amp, the screw terminals are used to attach the speaker wires. Sorry about that!
