The RMB-1504 Class AB 4-channel amplifier delivers 70 watts per channel into 8 ohms and 115 watts into 4 ohm loads with the continued commitment to performance without compromising the expertise of over 55 years of Rotel amplifier engineering, design and manufacturing experience. This amplifier provides power and refinement for object-based in-ceiling speakers in home theater installations and the demanding drive needed for custom installation and multi-room audio solutions.

12-volt trigger input and output connections, user-selectable audio signal detection power control, front panel volume attenuators, audio output link connections, 5-way speaker binding posts, and available rack-mount kit provide maximum installation flexibility.

A factory-built, oversized toroidal transformer and high-efficiency capacitors drive a series of high-current output transistors that ensure fast transient synchronization, precise detail, and controlled low-frequency consistency, regardless of speaker load capacity or cable distance. Maintaining crucial timing and energy while delivering effortless power is a distinctive feature of this amplifier that provides greater speaker placement options.

Critical evaluation of circuit design and meticulous selection of each acoustic audio component ensures precision, power and efficiency, all coupled with unparalleled build quality, ensuring this amplifier proudly carries the Rotel name.
