Know before you buy
Yes. Unlike some amplifiers that only reach their rated power when driving one or two channels, the RMB-1555 is rated to deliver 120 watts per channel into 8 ohms with all five channels driven simultaneously.
The Class AB configuration provides a strategic balance between high-fidelity sound quality and thermal efficiency. It ensures the amplifier remains powerful enough for cinematic dynamics while maintaining the precision required for detailed musical playback.
The 12-volt trigger input allows your processor or receiver to automatically turn the amplifier on or off in sync with your system. This eliminates the need to manually power the amplifier every time you start a movie or listening session.
Slit foil capacitors are designed to reduce internal inductance and improve the speed of energy delivery. This results in a more responsive, cleaner sound, particularly during complex or high-impact audio sequences.
The RMB-1555 is optimized for an 8-ohm load. While it is built with a robust high-current toroidal transformer, you should verify that your specific speakers are compatible with this power output to ensure optimal performance and longevity.
