I bought Ed's MKIII not for the digital input but something entirely different.

But, this had me wondering, why have a variable level control for a digital input?  Who records that way?  And what kind of AD would send a signal that needs adjustment at the recorder position?  I'm assuming all level adjustments were done at the pre stage.
A lot of people run a race to see who is the fastest. I run to see who has the most guts, who can punish himself into exhausting pace, and then at the end, punish himself even more.

It's a great field recorder, i did a few recordings digi-in to see what the problem is?
Mine sounded great....but they probably arent bit perfect from the source, oh well

I still have one and i use it!

The person I had corresponded with before has left the company, but my renewed request has reportedly been sent "to the product team for review". In the meantime, see http://taperssection.com/index.php?topic=192871.msg2322775#msg2322775 , which is very interesting.

I just did a bit of testing with the recorder set for automatic level control, which is something I would otherwise never have thought of doing. I fed signals into its digital input, and if I moved the record level controls, a sign came up on the screen saying "ALC" and the rec level controls had no effect whatsoever (which goes along with what I expected based on DATBRAD's message). I could turn them all the way up or all the way down; they were clearly out of the circuit (or the logic flow).

However, I didn't see or hear any actual ALC action from the recorder. I sent a set of overload-y signals in--repeatedly blowing into a mike that was connected to another recorder, whose digital output I fed into the Marantz--but there was no audible reduction in gain, and the meters registered similarly before, during and after the overloads.

So that's rather strange--but I think it might mean that the ALC setting, while not providing ALC, might provide 1:1 "bit bucket" capability. I can test for that, but it would take another hour's work or thereabouts, and right now I'm only awake temporarily (I hope) during a bout of insomnia, so I'll do that some other time.

--best regards
