The black Time Saving Devices TSD-PA122G 12W 2-Channel Power Amplifier from Atlas Sound is a reliable 4Ω stereo amplifier designed for general amplification requirements. The unit adds sound reinforcement to small projector systems as it can provide ample power to drive up to four 8Ω loudspeakers in a classroom or boardroom.
The TSD-PA122G Amplifier features a balanced stereo phoenix-style connector and unbalanced RCA input options with an output of 12W per channel at 4Ω, or 24W bridge mono at 8Ω. The 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.
This Time Saving Devices (TSD) Amplifier is designed to overcome some common audio system problems in an easy and efficient way. It is built with high-quality components and includes 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.
