Sonically and feature-wise, this is a decent recorder. In fact, it appears to be the only one on the market that isn't ruined by some blunder regarding dual recording (recording a second pair of tracks at a lower level, to as backup against clipping).

One of my favorite pieces of equipment...so easy to use and affordable. It does a great job, but burns batteries like a son-of-a-gun with phantom power...on just one mic. You should have many batteries with you if you plan to phantom power all four inputs on battery power.

This little guy may be small but it gives you a ton of control over your recordings. It's small profile keeps it out of the way, but is right there when needed.

I use this audio recorder along with my Blackmagic Pocket Cinema Camera. I've used high-end Sound Devices recorders and mixers, Zoom recorders, and the Tascam DR-60D and this recorder exceeded my expectations for the cost. Pros: - Surprisingly durable construction.

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...

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.

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

What else can I say other than yes? This makes my short film quality a dozen times better.

Finally, I have a great way to get amazing sound to sync up with my beautiful image that my DSLR provides. It's an easy to use, great sounding recorder. I shot a wedding with it the day after it arrived; I barely had time to learn it.

Good portable mixer and audio recorder. Wish there was a way to plug external power supply in.
