Olympus LS-100 Conference Recorder

LS-100 Audio Review

"It is, bar none ... the most fantastic handheld recorder I've ever reviewed! The only recorder that I've heard that's quieter is my Sound Devices recorder which costs thousands of dollars."

The portable Olympus LS-100 recorder looks weird, is built well and records like no other. The LS-100, like its spiritual ancestor the LS-10, is really designed for musicians and live music enthusiasts, but recording professionals and hobbyists will appreciate everything it has to offer: it can record, with minimal clipping, up to 140 dBspl of sound pressure; it has left and right phantom-power XLR inputs; the built-in condenser microphones are Olympus's most advanced ever; it has a built-in metronome and tuner; and an easy-to-adjust left/right balancer. You don't have to follow a rock tour to get the most out of this Olympus digital stereo recorder: journalists and podcasters will also appreciate getting the best natural sounds, from the splash of a rare Kingfisher to the roar of the crowd. On top of that, re-listening to your child's piano recital will never sound so good, even if it's bad. On top of that, re-listening to you kid's piano recital will never sound so good, even if it's bad.
