Due to space restrictions I'd need to place my Beogram 4000 further than the original interconnect cable will allow, but no further than 5m. Logically a female to male 5-pin DIN extension cable would make sense, however, would there be any issues to consider i.e. shielding / signal deterioration?
Any advice would be helpful!
MrRoast: 5 meters... would there be any issues to consider i.e. shielding / signal deterioration?

Yes.Even if you use a double-shielded cable (and that IS a must), there will be amounts of both loss and noise. It's generally not a good idea to make the cables longer than from factory.If you absolutely must, I suggest you fit a RIAA and extend the signal cable at line level.

EDIT: Second attempt at posting this.
Thank you Martin - thorough answer as expected!
I'll go via the RIAA route for the time being until I can get everything in the same place!
Hi MrRoast,
I agree with Martin, adding an external RIAA pre-amp close to the Beogram will allow you to extend the cable from the RIAA to the main system (up to 20m if required!) without any problems:-

Thanks Steve,
I bought a Beomaster 4500 a while back and the seller gave me one of those RIAA amps with cables for nothing - I only needed to get the PSU from Maplins!
I tried your and Martin's suggestion this weekend, connecting my 1202 up to my Beomaster 7000, and it worked a treat. The only issue is the that I'm having to crank up the volume more than normal to get the same 'level' - I believe this is due to the slightly lower output of the B&O cartridges.
Do either of you have any advice on adjustable gain RIAA amps?
Thanks
Dave
Hi Dave,
When using a good quality fixed output RIAA pre-amp, the level of the Beogram should typically be about 2 clicks away from that of your other sources, ie. to match volume 40 on CD or radio, go up to 44 on Phono. If the difference is much greater than this, then your pre-amp may not be up to scratch. As this difference in volume is usually quite small, there isn't really a need for adjustable output pre-amps in most cases.

In frustration, I turned to the variable output TC770LC from www.phonopreamps.com and was more than satisfied. I can highly recommend.

Thanks,
That is good to know. I will try one of these out. I would agree that low spec pre-amps can get noisy but a good quality fixed output RIAA pre-amp won't give any issues.
Thanks Graham & Steve,
As far as sound level I'm going up to around 56-58 on the 7000 - a lot higher than the 46 I usually have set, there's definitely more hum than if the 1202 is connected to my Beomaster 1200.
As for other preamps I've looked at the TC770 as I saw it referred to in another thread but was also looking at the Phono Box V (it certainly looks smart!)
As this is only a temporary arrangement I can probably live with it as is. Still looking for a Beogram 7000 in black though!

Not many were sold as B&O were actively convincing customers that vinyl was dead and CD was king.
