A few ADAT questions......

Postby roses2at » Thu May 08, 2008 6:16 pm


I recently bought a couple of s/h ADAT LX20's (don't laugh, but they were cheap and in good condition with low hours) and I have few questions about them. If anyone can help or shed any light, I'd be very grateful.

1) Can the Digital IN read a standard stereo signal via optical cable from a MD or DAT? Or is it only for 8 channel ADAT signals?
The reason I ask is that I want to transfer a few songs from my Korg D12, which I will obviously have to do two tracks at a time using MIDI sync. Would prefer not to have to do this via analogue.


2) Talking of MIDI sync, is it better to use the ADAT as a master or slave? (I have a BRC by the way.) Can someone point me in the right direction in the manual how to set this up?

3)I've seen a ADAT Remote Meter Bridge for sale but I'm not sure if it's compatible with the LX20. I see nowhere on its back panel to connect the RMB to. Someone told me they're only compatible with Blackface machines which strikes me as ridiculous. Why on earth did they phase out such a useful function on the later and more upmarket 20-bit ADATs??

Okay, plenty more questions still to come, but that's all for now.

Thanks.

Not sure about the litepipe question - never tried my blackface ADAT with anything other than an 8 channel ADAT to my MOTU. I would not laugh at ADATs - I recently bought one to transfer some masters and the track quality was stunning. And that was after the delivery guy dropped the box 5 feet onto stone floor :headbang:
If you have a BRC - then by all means use it. It's been a long time but if memory serves your top ADAT is the master and you daisychain down to the others from that one. BRC then connects to the top one. I'd slave the sequencer from the BRC too - if you are using one.

Apart from that - ADAT life is much easier if you follow the
'ADAT rules': FF/REW each tape before formatting so that the
tape is wound correctly on the spools. Once a tape is associated with a machine - preserve this relationship as the transports behave differently (in a subtle way). Use approved tape stock and do a 1-for-1 safety bounce of important projects. Clean, but do not overclean the heads with an approved cleaning tape.

Hope this helps, Rich

As far as I know it only works with ADAT format signals. However, I guess you could always try feeding it an spdif signal and see what happens. I suspect that it won't lock onto the signal.

Hmm, you're right. It doesn't see the SPDIF stereo signal from my MD or DAT. Which is annoying cos I want to transfer to ADAT from my other digital multitrack, a Korg D12.

Anyone know a workaround t"]this??

1) The ADAT lightpipe in is definitely ADAT format only, so won't accept S/PDIF.

2) Generally I found it easier to use the ADAT (the BRC in fact) as the master.

3) From what I remember, the meter bridge attaches to the BRC, so should work with the LX20s.

(I've still got a couple of black face ADATs and a BRC which I use for taking up space and putting things on top of, respectively, so I'm relying on distant memories here. I do have the BRC manual, though, so I'm happy to check if the meter bridge is referred to there.)

No, there's definitely no connection on the back of the BRC. (THat's what i hoped for originally, but logically, that couldn't work because there's no audio signal going from any type of ADAT to the BRC, only sync and track arm signals.)

Ah well, I'll be selling my two RMBs on Ebay soon (they each come with the 30 foot 4 way D-plug loom, mains cable and manual) so if anyone's interested, send me a PM. Would be prepared to split them.

Is there some kind of device (simple and cheap if possible)that can covert SPDIF into ADAT format??

I think that Alesis made a box to do this - the AI1 if I remember correctly.

Because the LX20 is the budget 20 bit machine. The XT20 was the upmarket 20 bit model. MIDIman/ Flying Cow made a little box to allow ADAT to S/Pdif routing.

I've just downloaded the manual for it and it seems to do what I want.

Anyone got one kicking around which they might be prepared to sell to save me trawling through Ebay?

What sort of price should I expect to pay??

What was it called? Or are you referring to the M-Audio SAM??

Again, anyone got one of them for sale for a reasonable and fair price?

Does anyone out there have a service (not operating) manual for the ADAT (any model would do, but LX-20 specifically)?
