The SD-20M is a simple-to-use solid-state recorder at "a breakthrough price". Featuring stereo RCA line-inputs on the rear, 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. Using the dual recording mode, users can capture a copy of the audio at a lower level, as an 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, whilst variable speed playback allows the playback to be changed without affecting the pitch.
Designed for installations in venues such as schools, houses of worship and conferences, the SD-20M is a flexible and affordable solution for long-form recording.
