The Tascam SD-20M is a 4-track recorder for installation. The 1-U rackmount includes a pair of microphone preamps with phantom power for direct microphone recording. Both the mic inputs and the line inputs can be recorded simultaneously in four-track mode. The dual mode captures a copy of your audio at a lower level, as insurance against distorted takes.
The SD-20M includes battery backup system: AA batteries can keep recording for hours in case of power loss. A wired remote or footswitch can be attached to control recording and playback. Variable speed playback allows the playback to be changed without affecting the pitch.
