The TSD-PA122G 4Ω stereo amplifier is perfectly suited to almost any general amplification requirement. Perfect for adding sound reinforcement to small projector systems, it provides enough power to drive up to four 8Ω speakers in a classroom or boardroom application. Output is 12W per channel into 4Ω or 24W bridged mono into 8Ω. Input is via balanced Phoenix-style and unbalanced stereo RCA connectors. Front-panel gain controls provide adjustment for left/right or bridged outputs and include removable knobs.

The unit requires a separately sold power supply to operate properly; multiple TSDs can be powered with one power supply depending on current requirements. This unit has a power requirement of 500 mA into 8 Ω and 1000 mA into 8 Ω, so you must use the TSD-PS24V500MA or TSD24V2500MA power supply. For multiple TSD applications, use the TSD Power Calculator to determine the appropriate power supply needed.
