Soundbox Posted March 24, 2011 Report Share Posted March 24, 2011 On my JE510 I have a feature which is A-B repeat. After selecting the start and stop times I get an endless repeat which can be set very accurately. I note that some newer decks do A-B repeat but with a gap between each repeat. Was the gap between each repeat seen as an improvement or was this due to other internal changes? I do use this feature quite often in my mixes (the last one was the repeat of the hard-hitting funk guitar licks from a Bing Crosby LP). So, what decks offer this feature apart from the JE510?

jim.hoggarth Posted March 24, 2011 Report Share Posted March 24, 2011 Hi Ian I stand to be corrected by some other expert, but I believe every deck has A-B repeat. It's part of the firmware from day one. Whether they all have the feature available from the front panel or the remote control is another thing, but I am sure even the thinnest of MD remotes has the A-B function? As for a gap, can't say I have ever noticed. How long is the gap? Microseconds or something silly like a second or two? If you ask nicely I will do some experimentation as and when I get individual decks on the bench. I have a JE510 and JE530 in front of me now, and should have an M100 out soon (although the M100 is basically the same as the JE520 and S40/S41 IIRC).

Soundbox Posted March 24, 2011 Author Report Share Posted March 24, 2011 Any of your findings would be much appreciated Jim. The gap I have heard on other decks (later models) is around 1 second - but my JE510 has no gap at all. I was trying out some of the MD decks in Cash Converters with my headphones and was surprised to hear the gaps. A-B repeat is useless really if it has a silent space (worse for short passages).

jim.hoggarth Posted March 24, 2011 Report Share Posted March 24, 2011 Any idea roughly at what model this gap may have appeared? Might save me some time checking everything. I have loads of JE480s in stock at present - would it affect this one? Jim Quote Link to comment Share on other sites More sharing options...
Soundbox Posted March 24, 2011 Author Report Share Posted March 24, 2011 Don't worry about checking them all Jim - I was just curious as to whether this was a known and documented issue. I have only ever tried a couple of decks so I cannot say for sure when the gap became noticeable. I don't think that many people used this feature - probably because of the poor (gappy)implementation in CD players. Quote Link to comment Share on other sites More sharing options...
jim.hoggarth Posted March 24, 2011 Report Share Posted March 24, 2011 Ian. Just tried this on a JE510, and even though you say it doesn't do it, this model inserts a pause between the A and B points. That even applies if the gap between A and B is only a second or so, which rules out some form of delay due to seeking the audio data start point as it should all be coming from buffer. The JE530 showed exactly the same half-second or so gap. Are you sure on this? Jim Quote Link to comment Share on other sites More sharing options...
sfbp Posted March 24, 2011 Report Share Posted March 24, 2011 Guys.... does the half second correspond to the S/PDIF setup time? Maybe it doesn't do it with analogue output? Quote Link to comment Share on other sites More sharing options...
jim.hoggarth Posted March 24, 2011 Report Share Posted March 24, 2011 This is independent of the SP/DIF. It's output anyway, not input. Using the remote you can set the 'A' mark, and then press again for the 'B' mark. In theory the machine then cycles through the same A-B section ad infinitum until the repeat button is pressed or a new A-B section is defined, carrying on from the end of the last 'B' mark. But on replay, there is a good half second pause before the section is repeated. I suppose the question is pretty academic anyway, as the only reason you would need a seamless continuation is in looping for musical effect and there are other ways to achieve this. A wannabee rock-god will presumably just be happy that they can repeat the guitar solo from 'Comfortably Numb' bar-by-bar until they have learned it by heart, anyway.

sfbp Posted March 24, 2011 Report Share Posted March 24, 2011 mea culpa. yes, I meant output Quote Link to comment Share on other sites More sharing options...
Soundbox Posted March 25, 2011 Author Report Share Posted March 25, 2011 Thanks for the comments. At the moment my JE510 is in bits undergoing restoration but I feel 99% sure that there was no gap between repeats as I have the results transferred to other MD's - on my mixes. Until it is back together and fully working I will hold off saying I am 100% sure! Saying that, this machine was purchaced under slightly special circumstances from when I worked for Dixons - and I feel that it may differ very slightly from other JE510's I have used.
