Hi Everyone,
I'm having some problems with my Beocord 5000 (pizza box version) and hope you can help...
If I record using Dolby C I get fluctuating volume especially in quiet passages, it also happens (but much less) with Dolby B, but it sounds all right (apart from the hiss) without any Dolby enabled.
Its the same whether I use fero or chrome tapes. I have recording levels set between 5 and 6.
Have a listen to the following recording and let me know what you think -
https://www.dropbox.com/s/saes9h3ic5mt3t4/beocord.wav
Its one file but its separated into 3 with a few seconds of silence in between sections, the first part is recorded and played back on a chrome tape with Dolby C enabled, the second is Dolby B and the third part is without Dolby switched on for both recording and playback. The CD that I recorded from sounds wonderful in the Beogram CD50.
Thanks in advance,
Lee
This is typical of badly calibrated Dolby circuits. You can't do that yourself I'm afraid; it is a highly specialized job.
But it can be fixed of course, and since the Beocord 5000 is an excellent deck, I'd have it re-calibrated.

Sounds expensive :-( why would it go out of calibration?
Just in case this helps narrow it down, it plays back pre-recorded Dolby B tapes perfectly.
I'm beginning to think it's related to the recording volume, I've just tried recording a chrome tape with the recording level turned-up to 7 and it sounds much better... Could the cause of the 'distortion' be recording level set too low? I recall reading about Dolby C suffering from a 'breathing' effect... maybe this is what I can hear...
Any thoughts?
What brand of tape are you using ?
Martin
Yes, breathing or pumping effect. Calibration, calibration, calibration. Dolby level must be thouroughly adjusted. Heads wear, components age you see!
Hi Martin,
Goldstar for the chrome and Sky brand for the fero... not the best tbh.
Could the problem be caused by the recording level been too low?
If you have a Maxell or TDK, I suggest you try it.
I use TDK SA almost exclusively. The results are impressive on both 5000 and 9000 Beocords.
I've just made a Dolby C recording on a TDK cassette and the results are impressive, even with the recording levels set low <5 I got no distortion as before....
Looks like its TDK from now on :)
Thanks again for all your help
