The RB-1552 has all of the advanced design features of the higher powered RB-1582, but with a slightly more modest output of 2 x 120 watts into 8 ohms. The rock solid power supply, select grade components, and refined sound are all hallmarks of Rotel’s nearly 50 years in audio design and manufacturing. RB-1552 features include 12-volt triggers for remote operation and an IEC detachable power cord.
