Description

The AtlasIED TSD-PA252G is a reliable, cost-effective stereo amplifier perfectly suited for almost 

any general amplification requirement. The unit is especially suited for adding sound reinforcement 

to small projector systems as it provides ample power to drive up to four 8

Ω

 loudspeakers in a 

classroom or boardroom application. 
The TSD-PA252G features a balanced stereo phoenix style connector and unbalanced RCA input 

options with an output of 25W per channel at 4

Ω

. Front panel gain controls provide adjustment 

for both left/right or bridged outputs and these removable knobs can easily be replaced with the 

included tamper-resistant security covers.
The TSD-PA252G is part of a full line of AtlasIED Time Saving Devices. These compact  

(1.5" x 4" x 5.2") units are designed to solve some of the common audio system problems in the 

easiest, most efficient, and cost-effective way. All models are made from high quality components 

and include removable individual I/O connectors for quick and precise wiring, separate ground 

terminals for all I/Os assuring secured connections, and removable level controls that can be 

replaced with tamper-resistant security covers. The TSDs are highly efficient and meet most energy 

standards as one 24V DC power supply (available separately) can power multiple Atlas Time Saving 

Devices.
