Easy-to-use, single-rackspace SD card recorder with XLR mic inputs. 

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. 

Designed for installations like schools, house of worship, and conferences, the TASCAM SD-20M is a flexible, affordable solution for long-form recording.

MAIN FEATURES 

XLR/TSR combo microphone inputs on the front panel

Four-track recorder capable of simultaneously recording from both the mic inputs and line inputs

Dual recording function captures a copy of your audio at a lower level, for a distortion-proof safety track

Can record a copy of the audio at a lower level according to the set audio recording level. This allows for a backup recording in case of distortion from unexpected loud noises.

In addition to the AC adapter, it can also operate using four AA batteries, which allows for recording to continue even if AC power is lost
