Hi Everyone, I picked up a Beomaster 2000 (2912) model as a bit of a treat to myself and I was hoping for some basic help to get started. 

I have a pair of Canon S30 mushroom speakers that I want to connect to the amp. However, the B&O connector plugs have me flummoxed. I am unclear what each prong does on the connectors and how to them up.

The S30 have 2 connectors with one wire going to each connector. The B&O connectors are the 2 prong type which use 2 wires per side. How do I correctly connect these speakers to some (aftermarket) B&O connectors? 

Proposed connectors

I suggest you ask Steve at Soundsheavenly in the UK.
He is the master when it comes to cables.

Using those red and black plugs in your post would be asking for trouble. They easily short and that'll take out your amplifier.

And those "strange B&O plugs" are 2-pin DIN and actually the only worldwide industrial standard for home-stereo speakers.
It's everything else, including those "strange springy clamps" at the back of your speakers, that are non-standard.

Pin is positive.
Spade is negative.

I feel very nervous here because I'm going to question Martin's wisdom...Surprise

Question 1 to tiktokrick - The photo of the white cable with B&O plugs on the end - are you in possession of this cable? If so, simply strip the ends to expose about 1 Cm of bare wire. put the cable with the grey line on it into the same coloured terminal of each speaker - it doesn't matter which terminal as long as both speakers are the same.

Question 2 to Martin - Am I right in thinking you maybe thought the same as me at first - that with the connectors, the screws that are visible are to close to each other, increasing the risk of shorting? The bare wire doesn't go around the screws - it goes into the holes and the screws then hold the wire in the holes. On this basis I would have thought that they were fairly safe?

I stand (well, I'm sitting actually) to be corrected!

Cheers

Nigel

Hi.

I guess you are unclear about the polarisation of the cables.

The small one (pin) is + (hook it up to the red side of your speakers)

The wide one is ground

The problems with those plugs are many.
The screws are not very good at holding the cables and the wires won't go very deep. The screws can barely hold the wires.
The wires - or even worse an amount of strands - slip out at even the slightest pull, and with some strands out the tension on the rest disappears.

The plastic gets brittle, they crack and fall apart. The red ones are particularly prone - but the black ones are bad too.
I throw them away every time I see them on things coming in for repairs here.

Or you can get a set premade from sounds heavenly. I wouldn’t cut off the female ends of the s30 b&o cables.
