The versatile Atlas Sound TSD-RL21 2x1 mic/line mixer is ideal for applications where paging, public address, and BGM music is required.
Use as a standalone remote mixer or in conjunction with Atlas Sound power amplifiers in applications such as conference center meeting
rooms, football stadiums, gymnasiums, retail/hospitality or other areas requiring versatile, multi-source mix control.

Channel one may be configured via rear panel dipswitch to accommodate mic or line level while channel two features a stereo summing RCA line level input. Both inputs are adjustable by front panel controls with removable knobs, which may be easily replaced by security, covers to prevent tampering. The remote level control feature allows use of the Atlas Sound AAVC-10K (or equivalent) decorative wall plate control for convenient remote adjustment of either the entire mix bus or RCA input 2 only (the typical BGM input).

The TSD-RL21 is highly efficient and meets Energy Star standards as one 24V DC power supply (available separately) can power multiple Atlas Time Saving Devices.
