DR-1 Portable Stereo Recorder
Item Summary
The DR-1 is a compact portable stereo digital recorder that captures hours of music to SD memory media. A built-in high-quality, variable-angle stereo condenser microphone allows the user to record from almost anywhere at MP3 or WAV file formats. Two microphone inputs are available for an external mono or stereo mic. The recorder includes auto gain control and analogue limiting for easy setup and a switchable low-frequency filter to eliminate handling or wind noise. One out of eleven effects can be applied to the input signal during recording. Recordings can also be added to existing audio files (overdub feature). And a host of playback features is supplied, including pitch and key control, a cancelling function as well as a tuner and a metronome.
The DR-1 comes with a 2-Gigabyte SD card and a lithium-ion rechargeable battery for many hours of recording time. An AC adapter and an accessory kit are available as an option
