I upgraded from the Tascam DR-40 to this, and I couldn't be happier. The preamps are superb, the features it has are perfect for my needs, and the design is great as well. The fact that this recorder is slim & lightweight, and also has tripod mounts on the bottom AND the top are a bigger selling...
Yeah, folks mention it can be noisy (somewhat) but for the price you get a really useful device, built in phantom power, flexible inputs, design works well under DSLR but have also used as a field mixer plugged into a broadcast level camera - though the connection is unbalanced.
best investment yet, if your wireless mics fail, this thing hasn't yet, very good backup, you just hook it up to the DJ station with the 1/4 inch connectors (not included) and hit the red button to record all the sound coming through the mics
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...
I bought this to replace my Tascam DR-40D and I'm immensely glad I did. I'm often operating a one-man crew and having the ability to mount this straight to the camera makes this worth the price alone.
I really like this recorder. Mounted it under my Nikon 5500, connected two shotgun mics to it. The 3.5 mm cable connected the DR-70D to my Nikon without issue. Recorded 14 ten minute interviews and all went well. For the price I would highly recommend.
I have recorded many interviews, including for state government, many short films and one feature and this device has been great clean sound and enough monitoring adjustments to get the right signal boost and noise reduction. Get the 6 battery extender to mount on top and you last all day.
A little time spent to learn all the features, but works great, very good quality recording. I set the gains to High+ to get enough volume, but that may be the microphones that I'm currently using also.
Thing is great. Easy to use, excellent recording using this with a RODE videomic Pro. There are a few things yet to play with, but overall I’m really liking the quality of recording I get.
I've been using this recorder for nearly two years at my film school, and finally decided to purchase one of my own. It is a great recorder, capable of capturing very professional sound if enough practice and patience is performed in using it.
