Tascam SD-20M Rackmount Solid State Audio 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. The dual recording mode captures a copy of your audio at a lower level. Designed for installations like schools, house of worship, and conferences, the TASCAM SD-20M is a flexible, affordable solution for long-form recording.

XLR/TRS combo inputs on the front for easy access

Mic and line signals can be connected to the 2 XLR/TRS combo inputs on the front. Their levels can be adjusted with the dedicated knobs.

Simultaneous 4-track recording from 2 Mic and 2 Line inputs

During the recording of a meeting, for example, while recording the line outputs of the meeting system equipment, you can simultaneously record two channels of mic input separately as a backup. In a music classroom, studio or similar situation, you can easily set up a system for multitrack recording and other uses using the line inputs for instruments with line output and the mic inputs for acoustic instruments.

Exclusive Dual Recording function

The dual recording function allows a file to be recorded simultaneously at a lower level in addition to the main recording. If the main recording should become distorted due to sudden loud noises, you can use the backup file recorded at a lower level. * When the dual recording function is enabled, only two inputs can be used to record.

3-way operation power for secure recording

In addition to the included AC adapter, the unit can also be powered by 4 AA batteries. If the AC power is interrupted for any reason, the unit will automatically switch to the AA batteries and continue operating without affecting recording or playback.

Conventional SD/SDHC/SDXC cards for recording

This unit uses SD cards, which are very common and easy to obtain, as recording media. Data files recorded with the SD-20M can easily be managed or copied using the SD cards themselves and a computer, for example.

Support SDXC cards up to 128 GB for longer recording

SDXC cards with capacities up to 128 GB are supported. You can continuously record even long meetings and rehearsals, for example, with peace of mind.

WAV/BWF high-resolution recording up to 96kHz/24-bit

Linear PCM recording is supported with resolutions up to 24-bit/96kHz. Since recording with high resolution is possible, you can capture music concerts and other important events with high levels of audio quality.

Supporting MP3 recording for extended recording times

You can keep the sizes of files created smaller by selecting an MP3 format. By using an MP3 format to record meetings, discussions and other long events, you can record for much longer amounts of time on the same card compared to when using a WAV format.

50 to 150% Variable Speed Audition function

The Variable Speed Audition (VSA) function allows you to change the speed at 50–150% normal speed (in 10% increments) during playback with this unit. Since the playback speed can be changed without affecting the pitch, this function is useful for language practice and meeting transcription.

XLR/TRS combo inputs and Mic inputs with phantom power

The 2 XLR/TRS combo inputs on the front support balanced +4dBu line level input from mixers and other devices. They also support condenser Mics that require +48V phantom power supply. These features enable a wide range of setups. The locking mechanism also prevents the unintended disconnection of cables.

RCA unbalanced inputs for mixers and other devices

The RCA unbalanced inputs on the back support –10dBV line level input from mixers and other devices. Together with the XLR/TRS combo jacks, they enable connection of a variety of devices.

Auto Rec function starts recording when input level is detected

The automatic recording function starts recording when the input level is detected. For example, you can use this function to record a radio program. By setting a timer for a radio tuner and putting the SD-20M in standby, the SD-20M will start recording when the tuner turns on at the set time.
