Bridged Mono Block Power Amplifier

The RB-1581 is the ultimate in Class AB power amplification delivering a massive 500 watts of output into 8 ohms. This mono block amplifier powers even the most demanding speakers yet accurately reproduces the details of your audio. Utilizing the Rotel Balanced Design Concept in the PCB circuit layout, custom designed and Rotel factory build oversized toroidal transformer, high efficiency slit foil capacitors in the power supply and discrete power transistors the RB- 1581 is pure performance.

The RB-1581 includes a rear panel mounted mechanical switch to select Balanced XLR or traditional single ended RCA inputs for ultimate connection flexibility. There are 2 sets of 5 way speaker binding posts supporting bi-amplification. A detachable IEC power cord and selectable 12 volt trigger with daisy chain output allows custom installation with ease.

Everything about the RB-1581 amplifier speaks of performance including the 4mm extruded aluminum top and side covers. The elegance of the industrial design, globally sourced sonic electronic components, Rotel signature DNA musical reproduction and factory built precision make this amplifier product to wear the Rotel brand. The RB-1581 is ideal for both 2 channel stereo applications as well as multi-channel installation in custom home theaters.

Power, performance, precision.

The RB-1581 is available in both Black and Silver finishes.

*Note – all Rotel 15 series components may be rack mounted and remotely controlled via RS-232, IR, or 12 volt (depending on model) for complete stealth operation.
