Simplified interface with controls on hardware switches and knobs instead of menus, for quick adjustment during a take
Dual record function captures a safety track to have a backup in case of distortion

    Tascam DR-70D reviews

    DR-70D 4-Channel Audio Recording Device for DSLR and Video Cameras is rated 4.2 out of 5 by 176.
    Rated 5 out of 5 by from A good compact recorder I use this to shoot double system sync with Pocket Cameras and the JVC LS300. I don't attach it to the camera, but have my sound person use it on a strap in the old Nagra style, with the optional external battery supply made for it. We phantom power a Sennheiser 416 on a pole, without a mixer or preamp, and the audio is excellent for documentaries. Since I only record one channel in my type of work, the audio monitoring complaint doesn't affect me. In fact, I set it at dual record and get two identical channels, with one set at minus 6db for protection. It's a very light and small unit, a real pleasure to use - reminds me of the Walkman Pro days.

    Rated 5 out of 5 by from simply amazing I do video production for a living. This is the best audio deck for the money hands down. The size of this thing is so much smaller than I expected. If you are doing audio production with a small team or by yourself the dr-70d is the only recorder I would invest in. I can be powered by usb power which means battery backup solutions out in the field become much more simple as any usb charger or battery back can be used. Getting to the SDcard isn't so bad that you should ignore this product. Battery life is bad for all these size devices but USB saves the day. My zoom h4n was worse and stopped working after about 100 projects.

    Rated 4 out of 5 by from correction to most useful negative review by Mobius Strip Mobius Strip wrote Nov 21, 2015 that the batteries are replaced by removing the entire front of the device, which then dangles by a piece of tape. Assuming that wasn't a misplaced review, it must have been a design flaw that has been fixed in the current design, since the current manufacturer reference manual shows the battery door is clearly on the back side of the unit (see page 12). Mobius' other complaint about external power coming in only on a micro-USB seems still valid, however for MOBILE sound (too easily bumped loose in a shoulder bag). But my only use is tripod mounted or desktop, so a little gaf-tape on the connection is all the insurance I need.

    Rated 2 out of 5 by from One of the recording ports does not work Was excited to get this to record for movies and reality shows only to find out that one of the recording ports does not work. I found this out after the 30 day return policy because I was only recording 2 people and didn't notice the issue until I started recording more than 2 people. Called Bhphoto for return was told this was out of the 30 day return and they told me to call the manufacturer because I had a 1 year warranty. Called TASCAM and in order to stay in queue for returns you have to continue pressing the number 1 every 20 seconds! Completely insane idea to have customers continue to press 1 or as they say your call will automatically be disconnected. This is the epitome of terrible customer service.

    Rated 2 out of 5 by from Great but not professional I have been using Tascam Dr60D for more than 2 years and recorded 3 movies and more than 20 short movies with it, Having an extra XLR input in the 70D makes this artifact incredible, leveling up the product to compete directly with other more professional items, this is what I tought until i got the tascam 70D, to make it simple, you cant monitor each channel individually like in the 60D, the monitor select button is gone and theres no another option, i have already sent emails to Tascam and they said that they wanted to make this product smaller, thats why some buttons are gone, and if more users complain about this they will start a firmware update to fix this, thats too bad, this is, at most, an amateur recorder right now.

    Rated 1 out of 5 by from Unreliable This recorder has caused me a lot of grief. Bought it to record a podcast using three mics that require phantom power. When I turn it on, it usually only picks up one of the mics, so I have to record the other two separately on my Zoom. On occasion I'll get lucky and it will pick up all three. I upgraded the firmware, and purchased an SD card that was on their list of approved cards. No help. I have a buddy who purchased one as well, and he's reported similar problems. I have a hard time understanding how this thing garnered so many positive ratings. Maybe we both happen to get recorders from some manufacturing run that produced bad recorders.

    Rated 4 out of 5 by from A bit complex but worth it. This is definitely not a tool for beginners, you definitely need a fairly decent amount of knowledge on audio and recording before using this. That being said I really enjoy this system. I am a wedding filmmaker and in the field this worked perfectly. The ability to record the same track twice with a different levels is perfect for weddings. I can't always monitor my recorders so this gives me a safety net. The preamps in this are great and the sound was perfect. I have used many other recorders including the Zoom H4n, H6, and other tascams, and this beat them all sound wise. The battery door is a bit flimsy and isn't connected in the most logical way, but it is functional.

    Rated 2 out of 5 by from Serious power issues, no one wants to honor the warranty... We bought this in September 2016. After a few months, we realized that something was not right with the internal battery life. After 20 minutes with two phantom powered Mics, the 4x 2700 mAh batteries are dead. B&H won't take it back as it is past the 30 day period. We have to send to a USA based servicing facility (we are based in Canada). But they won't ship back to outside the USA... We are pretty much stuck with a faulty unit. I hope someone at B&H or Tascam reads this and will be willing to help us as, as it stands, we are pretty disappointed by the Tascam brand after sale service...
