The RMB-1504 4-channel class AB amplifier delivers 70 watts per channel into 8 ohms and 115 watts into 4 ohms. The constant pursuit of performance without compromise, based on over 55 years of experience in amplifier development. The RMB-1504 multi-channel amplifier delivers the dynamic power and fine detail for Atmos ceiling speakers, for multi-room audio solutions, and for bi-amped front speakers. The RMB-1504 features 12-volt trigger inputs and outputs, a signal-controlled power-on automatic, front-panel input volume controls, audio link function for looping through the input signal, audio link output, 4 Speaker, and an optional rackmount kit, for maximum installation flexibility. Power-on 12 volt trigger automatic 4 x 70 watts per channel into 8 ohms

Class-AB amplifier design

The generously sized, special toroidal transformer, together with the high-power capacitors, drives a series of high-current output transistors that provide fast, accurate timing, precisely detailed and controlled bass – regardless of the power handling of the
Speaker and cable length, ensure. The balanced and musical timing – no matter what the power requirement, is a hallmark for this amplifier and allows its universal use. Careful circuit design and critical selection of audio components relevant to the sound ensures the highest accuracy, performance and efficiency. Together with the high build quality, this ensures that this amplifier can proudly bear the Rotel name.
