The Tascam iM2 turns the iPhone, iPad or iPod touch into a high-quality stereo recorder. The iM2 uses a pair of condenser microphones - the same high quality as Tascam's best-selling DR-series recorders - and plugs into the dock connector of your Apple device.The microphones are adjustable over 180 degrees for the best sound placement. The uni-directional elements are arranged in an AB pattern for detailed stereo imaging while capturing the ambience of your room.The iM2 contains its own microphone preamp and analog-to-digital converter for low noise and great audio quality. Unlike mics that use the built-in iPhone preamp, the iM2 can handle up to 125dB sound levels to capture the loudest concerts and instruments without distortion.Also contained in the iM2 is a stereo limiter to tame sudden loud sounds. The microphone level is adjustable with a knob on the side, making it quick to adjust without even looking at the unit. It's powered through the dock connector so no battery is required. A USB input is provided to charge your Apple iOS device for long recordings, either through a computer or Tascams PS-P515U power adapter.The iM2 works great with just about any recording app, including the built-in video camera. Record stereo sound while you capture hi-definition video on your iPhone to capture every moment with clarity and realism.
