TASCAM’s SD-20M is a simple-to-use solid-state recorder for demanding installations. The 1U rackmount includes a pair of microphone preamps with phantom power for direct microphone recording. Both the mic inputs and line inputs can be recorded simultaneously in four-channel mode. The dual recording mode captures a copy of your audio at a lower level, as insurance against distorted takes. The SD-20M includes a 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.
