Product Overview
A 4-track recorder designed for installation, the Tascam SD-20M is a 1U rack-mount unit that includes a pair of microphone preamps with phantom power for direct microphone recording. Both the mic and the line inputs can be simultaneously recorded in 4-track mode. The dual-mode captures a copy of your audio at a lower level, as insurance against distorted takes. Additionally it includes a battery backup system: AA batteries can keep recording for hours in case of a power loss. A wired remote or footswitch can be connected to control recording and playback. Plus variable-speed playback allows the playback to be changed without the pitch being affected.
