Topic: Tascam DR-70D 4-channel audio recorder for DSLR cameras

[Life In Rewind]

I am truly impressed with this recorder!!! I just wish it had the option to have 1/8" mini inputs too...

Pretty sure it does have 1/8" inputs...

1 set, channels 1/2 which means if you are going four channel the xlr are split side to side

Looks promising and a good price. I wonder how long tit will run on 4 AA.

That's 2 channel 16/44.1
4 would be less, ie most people will need external usb power

I think it's sort of interesting that Tascam appears to be publishing longer run times for the 70d than the 60d without phantom power, but running 4 channels of phantom power would probably suck 4 AA's dry pretty quickly.  I don't see a published spec at the link on battery life on phantom power which is also interesting. 

The member who actually has a 70d---what does it sound like and how long does it run on 4 channels of 48v phantom?  Inquiring minds cannot sleep until these questions are resolved.

2 channels at 48v phantom on alkaline a last 3 1/2 hours

What is the total current draw of the mics used for this test?

That is the quote in the reference manual.

My unit is due to arrive on Tuesday so I can do some in depth testing then.  I know there is one other who already has one on here.  Just let me know what you guys need to know and I can do some testing once it arrives.  The in-laws are in town so I will have to lock myself in my office anyway

That appears to be the spec on tascam us, but oddly not shown on the link I posted.  3.5 hrs of phantom power seems pretty decent.

Does anyone have this recorder yet? I am curious to hear some feedback.

Mine will be here this week and I will do a boatload of tests once received

No mention made of if the unit does auto saving?  This was a big pain in the ass on the 680, of you lost power during recording you lost the file.  Recovery was iffy at best and Tascam did not help with any kind of support for recovery.  Dos not seem like a big deal unit you lose power ehther with batteries going dead or cord unplugged .

Direct answer from Tascam regarding your concern:

After the DR-680, we fixed all our devices to be tuned to be
more sensitive to the battery voltage, and the recording is
automatically stopped when the battery goes too low.
If you keep AAs in, and power from a USB power pack, you
get a built in UPS functionality as well - it seamlessly
switches over.

So what happens if there is an abrupt loss of power IE: a  powercord being unplugged?  auto saved or not? That functions well ofr a gradual decrease in power.  Adn please don't say keep batteries in it. I get that but we are talking what if's here.  The loss of files was a HUGE bite in the ass when it happend mostly because of the relative inability to recover them

PSI got no horse in this race but it ended up being a real sore spot for me with Tascam and their support, so just a cuatinary tale

Since you bring this nuance up all the time...what decks DO "auto-save"?
