The DR-07 offers good recording quality and easy operation at an affordable price. The built-in stereo microphone enables you to record directly in MP3 oder WAV format. Alternatively, an external mic can be connected through a mini jack, or you can use a stereo line input with adjustable level for other sources. The recorder features auto gain control and an analogue limiter, a low-cut filter with three switchable frequencies, playback pitch and key control (combined or independently), loop playback, a 2-seconds buffer to start recording before the record key is pressed, a file divide function to cut unwanted parts of a recording, a USB port and a screw socket on the bottom to attach the unit to a tripod or microphone stand.
The DR-07 comes with a 2GB SD card and windshield and can be operated by two alkaline batteries or NiMH rechargeables – perfect for 7 to 8 hours of recording on the road. An AC adapter is available as an option.
