Topic: UA-5 > Microtrack 24/96: dropped samples

[Wiesel]

I recorded two sets last friday with my mics > UA-5 > Microtrack 24/96 gear. The first set came out perfectly, but the second one is missing samples at a few places which I noticed because I wanted to synchronize it with a SBD feed. The recording is about an hour long and there are five or six places where something is missing, at one place it's even two seconds.

I have no idea why that happened, but my suspicion is that either one device is bass sensible (it was a very bass heavy show) or that it got too hot (I didn't turn off the gear between the 2 sets). Did anyone ever experience something similar with this gear? Or does anyone have an idea why that happened?

the only thing i can tell you is that my mt will get hot
hot enough that you don't want it in your pants for 3hrs
never had an issue though

I would suspect cable connections.  When this happened to me with UA-5 > optical > H120 I would replace the cable.  Since coax cables seem a bit more solid I generally just clean the ends with Qtip and alcohol and try not to "mess with the gear" in the bag... Put the MT in a position in your bag so you can see it without having to pick it up to look at it... every time you wiggle it you stand a chance of disrupting that connection which is flowing a bazillion bits per second and would need to resync if disrupted.

mine also gets hot as hell but I've never experienced that issue before... maybe heat really isn't the cause.

I had the MT laying on my bag and didn't touch it a single time except for starting and stopping the recording. I'm using a coax cable but I can't believe it's the cables fault since the first set came out flawless. Like I said I didn't mess with the gear but the heavy bass might have shaken it. I'll check the cable anyway since it's the only thing I can now do... the problem is I have no idea how to reproduce the situation to verify if the error is present or gone...

The only time my MT ever dropped samples (twice) it was the exact same rig in the exact same venue -- running a matrix (SBD + Neumanns) into the UA-5 > MT (24/48).  There was no issue of heat (2 short shows -- have run hours longer with no issue), cable connections (no other problems ever) or bass-heavy-ness (one band didn't even have a bass!).

I thought it might have something to do with the power coming from the board, but really I have no clue.
