Rotel RMB 1504 - 4 Channel Power Amplifier

The Rotel RMB-1504 is a 4-channel Class AB power amplifier delivering 70 watts per channel into 8 ohms and 115 watts into 4 ohms, building on more than 55 years of Rotel amplifier design and in-house manufacturing. It suits both home theatre installations and custom multi-room audio solutions where four channels of solid, well-controlled power are needed.

A 12-volt trigger input and output are joined by user-selectable audio signal sense power control, allowing the RMB-1504 to switch on automatically from either a trigger voltage or an incoming audio signal, whichever suits the installation.

Why Consider the Rotel RMB-1504

Four channels covers a 4.0 zone, a pair of stereo zones, or the surround channels of a larger home theatre system fed from a separate front-channel amplifier. The choice between 12-volt trigger and signal-sensing power control means the RMB-1504 fits either a fully automated custom installation or a simpler system that just needs to switch on when it detects audio.

Ideal For

• 4-channel or dual-zone custom installations
• Surround channel amplification alongside a separate front-stage amplifier
• Systems using either 12V trigger or signal-sense power control
• Multi-room audio solutions needing rack-mount amplification
