M Audio Microtrack 2 writes the recorded material to Compact Flash memory cards or microdrives.Microtrack 2 is equiped with 2 high-quality microphone pre-amps, Line level analog inputs, an S/PDIF coaxial (RCA) input, analog Line level (RCA) and headphone (mini-jack) outputs, phantom power for microphones and separate input level controls for each channel.

It has a USB 2.0 interface, and commes with a rechargeable Lithium-ion battery. The recordings are made in uncompressed WAV and BWF files , both 16- and 24-bit formats at sample rates from 32 to 96 KS/s. It can also record MP3 files at 96 to 320 kbps. While recording it allows monitoring via headphones and the Line outputs.

What's improved? A limiter has been added to the Microtrack 2 to keep control over the input signal so distortion from unexpectedly loud sounds will be eliminated.There is no need to worry about losing any data when the filesize reaches the maximum of 2 GB. Microtrack 2 creates a new file and continues to record.The microphone pre-amp has been giving a wider range of loudness without any distortion or overload.The incomming signal can be monitored over headphones so you'll always have full control over what you're recording.The Phantom power supply offers 48Volts.
