Hopefully my BM6000 quad can be repaired so for my BG6000 I'm looking for a quad/SQ4 Pink Floyd Dark Side Of The Moon album.
Are these hard to find and can it be used on my BG6000 recordplayer? What's the difference anyway between SQ4 and CD4?
Brengen & Ophalen
I have no idea but I'd suspect they are hard to find.
The difference between CD4 and SQ4 is that CD4 was a discrete 4 channel format, 4 independent channels, encoded in very high freq content, which required the Shibata stylus to get the signal off the LP. SQ4 was a matrixed surround like the original Dolby ProLogic surround sound. The rears were both the same signal, and it was ambience not discrete channels. On CD4 you could get a different instrument out of each speaker, not so for SQ.

I'm afraid I'm recovering from the BeoVirus.
Thanks Jeff, understand completely!
Hi Leslie,
is that the Beogram 6000 I was hoping to buy from you but then didn't hear from you again? Anyway, they come up on eBay sometimes:

They are quite scarce. I go to a few vinyl sales here in France and have never come across a copy of this in CD4 or SQ4.
Good luck in your search.
Dave.
They do come up but are expensive. Do remember the following - SQ records as stated above are matrix recordings - you can paly these on any deck and the decoder is in the Beomaster 6000 - in my experience underwhelming! The CD4 records are the real McCoy - four separate channels. However they are usually pretty poor as well - either the production jumps the sound around to 'impress' the listener or someone has played the record with a heavy tracking cartridge and the rear channels sound distorted. You do need a really good cartridge to play CD4 records - this is the one time where aging cartridges can be detected. I think the B&O fanatics all go through a quad phase - it all seems such a great idea - reality kicks in pretty soon though - I got rid of my system though I do have the BM6000 somewhere. Quite frankly it just isn't as good as a well sorted stereo system!

Quite right about damage to CD4 LPs. Back in the day my friend had a cheap Panasonic quad system, all in one. A CD4 LP would survive about two playings on that crappy turntable, I always thought selling it as CD4 capable was tantamount to fraud.
Another tech that was ahead of technologies ability to support at the time. Now that there's a lot of good approaches for multichannel music, DVD-A, etc. everyone has lost interest.
were there more standards at the time then sq and cd4?
My re-capped M75 are my precious diamonds.
There was another matrix one called QS (confusingly!) I don't know if the two types were similar or if the decoders worked on either. CD4 was also called quadradisc.
I bought 5 Quadraphonic SQ records some time ago on a fleemarket, thought I should try them our for fun, at some time. Then I guees correct, it is just outphased information, just like the later patented Dolby Stereo.Interesting test you can do, is to activate the SQ button on a old quadraphonic reciever playing some MP3 material and listen to what comes out through that channel. Its more or less just digital rest products.
Dave Farr:is that the Beogram 6000 I was hoping to buy from you but then didn't hear from you again?
Hi Dave, I remember we had some email talks about that and from my memory I was the last who replied? Told you about the new dustcover I made for my BM6000?
I have two BG6000's now.

my recollection is that I told you I'd actually be more interested in a BG 3400 to go with my BM 3400 as I already have a non-working BG 6000. I didn't hear back from you. I knew you had health issues with your eyes so didn't want to push it.
Have you found the vinyl yet?
The problem with the BG3400 is that most do not have the CD4 decoder in them - it is an optional kit - I have only seen one which was lost in the Bellac adventure - I had a 3400 and the decoder separately but the decoder disappeared. I would suggest the Beogram 6000 is the one to have anyway as tangential tracking is probably particularly good for CD4 records and contact line styluses. The Beomaster 3400 is however in my opinion the better performer compared to the Beomaster 6000, though nothing like as dramatic!
The Beogram 3400 usually has a small black plastic plug just above the printed name - if the kit is fitted, this is replaced with a red LED.
Hi Peter,
yes, I know that. I would just like a BG 3400 to complete the system. I already have one BG 6000 (and the BM 6000) awaiting service. If Leslie had a BG 6000 fully working at a reasonable price then I'd take it but I haven't received a price from him.
I should have guessed! I did much the same! The BG3400 is a very elegant deck - slim and it is among the first of the MMCx000 carrying decks. Mine had a MMC5000. I always liked these decks as they felt solid and the arm, though very light , seemed more substantial than the later radial decks. I think I have the lid for one somewhere!!
I bought a really nice BG 3400 and it arrived in pieces! The lid is completely smashed and only fit for the bin I'm afraid. It does not have the optional decoder in it - I opened her up (didn't take much considering the state it arrived in). The tonearm and motor all work and it does hold speed and will play a record but will need a lot of work.
If you would like to be liberated of the lid, let me know! If you need it for a future project, that's fine.
I don't know how feasible it would be to construct a duplicate decoder for the deck? I think it's been covered before from my failing memory.
Best,
Dave
I'll see if I can find it - it will only be collecting dust! The ciruit for the decoder should be pretty simple - I will see if I can find the diagram. I have a feeling it came with the kit but I may not have scanned it.
Here an indicative address for Dark Side of the Moon:

Thanks guys! There seems to be another Pink Floyd album Atom Heart Mother recorded in SQ4 (thanks Alain ). On the search for that. Meddle as well?
Here is one possible source for Atom Heart Mother:

A bit expansive, I will check if there is cheaper else where
Bought Dark Side Of The Moon SQ4 for 30 euro on Ebay :-)
Leslie: Bought Dark Side Of The Moon SQ4 for 30 euro on Ebay :-)
Please post your impressions when you get to hear it. I didn't know there was an SQ version, I'd only heard about the CD4 one.
I will Jeff. Olly (Step1) is taking care of my quad 6000 so when that thing is repaired (hopefully he can) I will post pictures of the complete setup.
Hi Leslie
Did you have the opportunity to put in place a complete quadraphonic set up?
Any comments or feedback if so?
Cheers
Not yet Alain, it's still with Olly (Step1) for repair BM6000.
But I got my Pink Floyd SQ album
Holy carp! How much B&O do you have? That's a load of pizza boxes!
That's just a part Jeff!
