Specifications and features  

 

 

 
This small amplifier is constructed with the TDA1521 IC, with a maximum supply capability of 2 x 15Wrms (4ohm) of 2 x 
10Wrms (8ohm). The IC is thermally and short-circuit protected.  
Additional rectifier and smoothing filter are unnecessary, as alternating current can be directly connected to the unit.
