Topic: TASCAM DR-680 portable 8-track #3

I bought one of these:

but only using it for my USNPre2 so far.  I want to try it with the pre and the 680.  One thing you will not like is the lack of any kind of charge indicator

This is the same battery I use with my DR680.  It's been reliable, so far.

How long did you run it?  How many channels did you use?  Was phantom power on?

Well, the longest I've had occasion to run it so far was about 2.5 hours with 6 channels (4 channels phantom and 2 channels line in) at 24/48.  Since there's no battery meter I had no way of knowing how close I came to draining the thing.

Anyone use a Kingston 32 gig class 6 sd card?
On sale for $50 at buy.com today, thinking about doing it...

Have kingston 32 GB class 4 SD card and have run 24/96 with 6 channels no problem.

Manual file splits by pressing the record button should be seamless, tmk. Pre-recording is not in effect once you are in record mode, so there won't be overlap between the files.

Exactly what I was going to say. Thats how the 722 does it too!

Thanks Bean and others for their comments.

Will try the record button to create new files...

I have two of these and I have run it for 6.5 hours and then stopped it, but I don't know how much juice it had left. That time I had two channels with phantom power.
I have used them in really cold weather and they work fine.
There is a problem with both of them that is annoying...
When I switch it on and have it close to 680 there is a signal that gets recorded... I don't have to have it connected to 680. I can hear the signal just holding it close to my ear.
It ruins the recordings... getting a signal at 4000, 8000, 12000, 16000hz and so on...
The problem is solved by getting the battery away from 680 and a 1/2 meter is enough. The default cable must be stretched fully to avoid the signal. I have made my own cable now with angled connectors and it's a bit longer than the cable that came with the battery.
It's a drawback to not be able to have it in the same case. Especially when both of them fitted in the extra pocket on the 680 case. I just have to remember to take them out and put them away from the recorder when i use them.
Does anyone know how to fix this? It guess it's the on/off switch that is bad. I haven't opened them up yet.

That is because of the regulator circuit for the +9v and +5v... just the straight  battery would be better

I don't mean to get off topic but does anyone know if this could be used to power the UA-5?

[kirk97132]

should work but Edirol needs negative center pin

Tested out pressing the "RECORD" button on the tascam DR680.

Anytime you push record while recording the tascam will create a NEW seemless file.

---------------------------------------------------------------------------------------

PS: Found out if I don't power things up (batteries/preamp and recorder)in a certain order the tascam DR680 does not see the incoming signal correctly from the V3. Channel 1&2 were connected to the V3 and channel one kept overloading even at 0 DB for output on the V3 knob for that channel. I reconnected all wires in back and the SPIDF was not tightly screwed on. So retighten SPIDF and reconnected. Then repowered up v3 and tascam and channel one was not overloading.

Good stuff. Thought one DPA was having a problem but it was PILOT error...

A recent issue has developed with my 680.  My analog input #2 has dropped by 10db.  Anyone run into this?

You probably did this already, but double check your mic/line, hi/low gain switches on the top of the unit.  One of those may have just gotten bumped.

thanks, but it isn't that, the limiter, cables or mics.

[kirk97132]

any chance something got changed by menu selection?  IE: limiter.   Just guessing at this point.

[tgakidis]

checked all that unless there is something else i am missing.  Smokinjoe suggested cleaning the contacts but I haven't tried that yet.

[NOLAfishwater]

ted, have you checked the whole chain? caps>mics>cables?
