Ok, so I thought my first project with the 680 was flawless from last Friday (Warren @ Orpheum Boston). Ran 4 channels 3 & 4 direct and dig in via the V3. Great recording until I got around to mixing down and processing the 2nd set this past weekend and realized a segment of the file toward the end (approx 12 minutes) has intermittent clipping. But then the final 5 minutes of the encore is fine. I have narrowed it down to the direct source (ch 3 & 4) as only that source and the mixdown have the problem but the stereo channels/tracks are fine. As such I figure it must be the 3 & 4 pres or maybe the card. I was careful with the card purchase and bought one of the 32 gig sanctioned cards from the tascam list and formatted prior to use so leaning away from that being the issue. Also I was using a dvd 9 v battery that had plenty of power remaining at the end. Any ideas what it might be would be appreciated. Next up is Mtn Jam on 6/4 so it will get a good work out and I will be sure to monitor and troubleshoot starting with trying channels 1 & 2 for the direct source. Again, glad I bought the B & H extended plan, but hopefully won't need it. . .
Ran the 680 3 times this past week.1)
First time was running 680 with channels 1,2,3,4 from a Naint Big Box and V3 with 2 sets of DPA mics. No problems all files came out. Recording sounded really good and no clipping on 680.
2)
Second time running 680 was with 6 channels 1,2,3,4,5,6. Channels 1-4 for 2 sets of mics (front of lip) and channels 5-6 for SBD patch. Channel 1 was overloading ONLY at end of show for about 15 minutes. Almost like levels double and clipping happens all the time on 680. I did not notice the V3 having problems. In wavelab listend to channel 1 and clipping sounded like constant digi-noise.
3)
Third time running 680 was with 6 channels 1,2,3,4,5,6. Channels 1-4 for 2 sets of mics (front of lip) and channels 5-6 for SBD patch. This time it was Channel 3 was overloading for most of the show. Did notice this time big jumps in the V3 that I never noticed before. Was recording with first 2 greens lights on v3 and occasionally hitting 3rd green light then all of a sudden it just jumped into the first red light and occasionally the second red light. Like a 10 - 20 DB gain or more. None of the other channels showed this behavior. When listening in wavelab channel three sounded like complete garbage no music at all just digi-noise during the times it clips. First 5 minutes sounded fine thou with channel 3.
Comments:The above never happens with the Big box only with v3. I believe during the 3rd night I switched the mics from the second night so it would make sense that channel 1 and 3 problems experienced above are probably the same mic. Think the first night the music was not that loud and mics might just not had enough SPL to clip V3/mics/680 pres. The second and third nights the music was very loud on stage with front of lip recording.
Was not really sure what was happening?
(Still not sure if its the my mics, cables, V3 or 680?)
Mics: DPA4022 and 4027
Cables: Most brand new from tgladis
V3 I bought new about 2 years ago.
Card is kingston 32GB class4 (also have 2 16 GB kingston Class 4 cards)
Batteries for 680 is a tekkon with extended battery pack and is set to 12 volts.Batteries: V3 is set to 6 volt and runs off a single tekkeon(I live in boulder and had grace change the V3 from 12 volt to 6 volt due to it was really hot in a fanny pack during recording, so he said at the time since my other recorder was not 12 volt to change it to 6 for the heat issue)
Any comments on my comment or the above comment would be appreciated.
Thanks.
