ROTEL RMB-1506

The Rotel RMB-1506 is a robust and sophisticated multichannel amplifier designed for those who want to distribute music across multiple rooms in their home with reliable and controlled performance. This amplifier delivers 6 × 50 watts per channel, providing sufficient power for less complex multi-zone audio systems while maintaining the quality and precision typical of Rotel products.

The RMB-1506 integrates seamlessly with Rotel surround receivers or preamplifiers/processors, allowing it to power up to three additional rooms or “zones.” Thanks to the buffered output, additional amplifiers can be connected to create larger multi-zone setups without any loss of signal quality or control.

The RMB-1506 offers all the features needed for flexible and customized installations: front panel volume attenuators for each channel, easily connectable audio inputs, 12 V triggers for automatic power on/off, buffered output for system expansion, five-way speaker terminals for secure connections, and a detachable IEC power cord. The combination of power, flexibility, and solid construction makes the RMB-1506 ideal for anyone seeking a user-friendly multi-zone amplifier capable of delivering clear, dynamic, and reliable sound throughout the home.
