The RMB-1504 Class AB 4-channel amplifier delivers on the ongoing commitment of performance without compromise building on over 60 years of Rotel amplifier design and in-house manufacturing of Hi-Fi electronics. This amplifier provides the power and refinement suited for home theater installations as well as custom installation multi-room audio solutions.
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 andhigh efficiency capacitors drive an array of high currentoutput transistors ensuring fast transient timing,accurate detail and controlled consistency of lowfrequency regardless of the loudspeakers load ratingor cable run distance. Maintaining crucial timing andenergy while delivering effortless power is a signaturetrait of this amplifier providing increased speakerplacement options.
Critical evaluation of the circuit design and meticulousselection of each acoustic audio components ensuresaccuracy, power and efficiency all coupled with anunsurpassed build quality ensuring this amplifierproudly wears the Rotel name.
