Rotel RMB-1504 Four Channel Power Amplifier

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 ongoing commitment of performance without compromise building on over 60 years of Rotel amplifier engineering, design and manufacturing experience. This amplifier provides power and refinement for object based overhead speakers in home theater installations and the demanding drive required for custom installation and multi-room audio solutions.

The 12 volt trigger input and output connections, user selected audio signal sense power control, front panel volume attenuators, audio output link connections, 5-way speaker binding posts and available rack mount kit  (rack ears included in some markets) provides ultimate installation flexibility.

An oversized factory built toroidal transformer and high efficiency capacitors drive an array of high current output transistors ensuring fast transient timing, accurate detail and controlled consistency of low frequency regardless of the loudspeakers load rating or cable run distance. Maintaining crucial timing and energy while delivering effortless power is a signature trait of this amplifier providing increased speaker placement options.

Critical evaluation of the circuit design and meticulous selection of each acoustic audio components ensures accuracy, power and efficiency all coupled with an unsurpassed build quality ensuring this amplifier proudly wears the Rotel name.
