Summary: I bought this to use professionally with a Canon 60D. This recorder is amazing. It has a headphone out and another output for the camera. I've used it on many professional projects with dozens of satisfied clients over the past 3 years. The best feature to this product is it's dual batteries. I can charge the battery via USB, and use AA batteries at the same time. I DEFINITELY RECOMMEND THIS PRODUCT!
Summary: Excellent digital recorder. Recordings are very clear and dynamic and don't distort if you choose the right setting. There are many options on this recorder such as playback at different speeds which doesn't change the pitch, and overdubbing. There are two internal mics but also has the ability to take two XLR external mics. Great recorder-highly recommend!
Summary: Tascam usually makes decent products. This is not one of them however-which I didn't immediately realize. The SHORT: it either crashes, shuts off, or has a file record error at the worst times-do not trust the DR-100 if you need a reliable device to record sound when it counts. When it does record it does so very well, but if you are on a set and it's time to "roll sound" then count your blessings.
Summary: I used this to record audio for an independent film, using the XLR inputs. The quality is good, but I ran into severe problems with the battery. After the Li-Ion rand out (about 4 hours of intermittent use) I had to change out AA batteries every hour. It caused some delays which I do not think is acceptable. I'm returning it and ordering the DR-40 which was just released and hopefully will prove to be a much better fit for me.
Summary: I have used digital audio recorders for years, from $17,000 Sony DAT machines, through the Zoom H4 and then a Sony PCM-M10. This little wonder has them all beat for sound quality, ease of use and versatility. The built-in Uni mics are quiet, have good freq. response, and give a very realistic stereo image.
Summary: I bought the DR-100 to record my music and selected it over others because it had a speaker. The speaker was poor quality and recording volume was also low. Had I known the speaker was unable to properly repoduce Guitar sounds, I would not have bought it. I purchased the GT-R1 after returning the DR-100. I use a headset with the GT-R1. The GT-R1 is what I should have bought initially. It is much better for a Guitar player than the DR-100.
Summary: It's a good option for the price, but there are a great opportunity to do more for it in the future. Weak construction in general, weak precision pieces (e.g, the switch on the back, the locking system for the internal battery, the old fashion screen)... It's OK, but maybe there are better options for the price, really I don't know.
