Topic: TASCAM DR-680 portable 8-track #6

[2manyrocks]

  Can you use a Sound Devices 702 or 744 to use channels 7 & 8 on the 680 via a S/PDIF?  I'm sort of thinking I want one of the SD units for my main two mics, but would be content to use my 680 for spot mics if these units will work together like this. 

[Gutbucket]

Yes.  The clock on the 680 will slave to that of the SD across the SPDIF link.  You'll need to start the transports separately, and line up the resulting files recorded on the two different machines afterwards, but they will share clock-sync.    You can either choose to record the stereo SPDIF input on the 680 or not, it's not required that you do so to sync the machines. If you do, you won't have to do any file aligning between that SPDIF stereo channel and the others recorded on the 680.

Thank you.

Hi all, I'm running the new 680 for the first time tonight and have a couple questions. Forgive me if these have already been covered, I haven't had a chance to dig in to the other 680 threads yet.

What's the process to gang/un-gang channel's? I've read the manual but it's not explained very well. Is it really as simple as pressing the the 2 channel buttons on either end of the group you want to gang? Can this be done at any time or only while monitoring/recording? I assume you reverse the sequence to un-gang groups?

I plan to run a 5 channel mix, 2 mics onstage, a stereo SBD feed and a 3rd mic towards the back of the room. Is it possible to create stereo files for the 2 stage mics (1/2) and 2 SBD channels (5/6) then record the 3rd mic (3 or 4) as mono? I'd like mix everything to stereo on the fly but need to be able to split the 3rd/mono mic between left and right.

Is there a way to add delay to any of the channels? The 3rd mic will be about 30-35' away from the stacks. If I can't add delay I'll need to remove it from the stereo mix and add it back in post.

Apologize for all the questions.     I'm a little stressed about running tonight, I'll practically be un-boxing 680 at the venue before the show starts.

Press and hold the button for one channel, press the button for the other channel, let go. Order doesn't matter. Can be done any time.

With this unit, a group of audio files that are recorded at the same time are collectively called a “take.”

Depending on the file recording mode setting, the files included in the recorded take will be as follows.

Example 1: 6 tracks and a stereo track recorded

• MONO format set: 6 mono WAV files and a stereo WAV file
• STEREO format set: 3 stereo WAV files of inputs pairs 1-2, 3-4 and 5-6 and a stereo WAV file of the mix
• 6ch format set: a 6-channel WAV file and a stereo WAV file

---

There's no way to have stereo files for 1&2 and 3&4 and a mono file for 5.

Is there a way to add delay to any of the channels? The 3rd mic will be about 30-35' away from the stacks. If I can't add delay I'll need to remove it from the stereo mix and add it back in post.

Nope. I'm not sure what you mean. Why can't you just record the 5 tracks as-is and shift around (if necessary) when mixing?

No delay available on the recorder.  You'll need to shift/delay as required later.  Set it to write 6 mono files to make doing so easier.

Thanks lukpac!

So it sounds like my only option to mix the 3rd mic into the stereo mix, without recording an unneeded 6th channel, is to use the MONO format with the stage mics and SBD channels panned full left/right and the 3rd mic center panned. Does that sound right? Can you gang channels running in mono mode?

For my delay question, I'd like to get the stereo mix as close as possible at the show. With the 3rd mic being a ways back from the PA there will probably be a noticeable delay in the mix if I can't delay to the other channels while recording. Channels can be individually delayed on the DR-70D so it seems like this would be an option on it's big brother, the 680.

I know my chances of getting my the stereo mix right at the show are slim but I run a lot of matrix's at this venue and if I can get mixing dialed in over the next few shows it'll save me a ton of time in post.

Yes to both questions.

It should be a feature on the 680, along with polarity invert and EQ, but unfortunately is is not.  These features are not included in the new 680mkii version either, which is my primary gripe with the new version.

The stereo mix (essentially the 7th and 8th tracks) is independent from 1-6 as far as format goes. That is to say, it doesn't matter how you save 1-6. The format for those will have no effect on the stereo mix. You need to use MONO to prevent recording an unused 6th channel, but that has nothing to do with the stereo mix.

Yes, you can gang channels in any mode.

Yeah, no option for delay on the recorder.

Usually that amount of delay is probably welcome, although I suppose it depends on the venue and personal taste. And I almost always use EQ and compression anyway, so for me the stereo mix wouldn't be anything more than a rough mix to sample until I did the real thing.

I'm running the mkii tonight, wish I knew these options were missing before I bought it. Cue buyers remorse...

This seems like a major oversight on Tascam's part, maybe they can add some of these options via Firmware updates?

Yep, get two of these, and give one to me

Tascam updated the original 680 firmware at least once and issued new firmware for the mkii when it was released.  Sorta doubt they will add more features.  If you're serious about buyer's remorse and still have the option to return it, you might consider this.

680 operation is not as easy as the 60d or 70d, IMO.  I was hoping for a mkii version more along the lines of the 70d myself.

That's my somewhat doubtful hope. Not sure if it's possible, and if it is if they will have enough incentive to do so.

Please complain about this loudly to Tascam!  If enough users do so, they may work to implement it if possible.  As a new owner of the mkii, Tascam should be more open to your concerns than the rest of us!

There were 3 or 4 firmware revisions on the 680 (I never implemented the last, which was mostly an mp3 update as I recall).  The early updates offered a few major feature improvements however, which included the channel ganging feature.  This all hinges on if there is the DSP processing power and architecture available in the machine to implement those features.  If not, Tascam should have added that with the mkii hardware updates.  The 70d doesn't feature channel ganging, which is a deal-killer for me (and I need more than 4 channels too).  It doesn't appear channel ganging could be added easily to the 70d due to it's analog gain pots.  If they were infinitely rotatable digital control pots instead, they could add it while retaining the easy "twist a separate physical knob for each channel" interface.

2manyrocks, If you return it please tell Tascam why you are doing so, not just the retailer, so that they are made aware of this stupid design mistake.

Cool box.  Except he'd need both of them delay the other 4 channels, and preamplification/phantom for two of those as well.
