The SD-20M is a simple-to-use solid-state recorder at a breakthrough price. The 1-U 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-track 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.
Designed for installations like schools, house of worship, and conferences, the SD-20M is a flexible, affordable solution for long-form recording.
