Rotel RMB-1575 Five-Channel Class D Power Amplifier



The Rotel RMB-1575 is the multi-channel powerhouse of the Rotel's 15series that utilize both the ASP and A modules to create a powerful amplifier. By using two of the powered (ASP) modules for the front LT/RT Rotel then powers three additional passive (A) modules for the C/SL/SR channels. This sharing of power supplies could potentially decrease the available power to all channels, yet Rotel claims that the RMB-1575 is able to deliver 250watts a channel, with all channels driven (20-20 kHz, 0.03% THD, 8 ohms). This is an impressive amount of power for such a relatively small amplifier.
