Built with installation in mind, it offers a practical way to power multiple zones or additional speakers from a single, well-engineered component.\u003c\/p\u003e\n\u003cp data-start=\"387\" data-end=\"717\"\u003eEach channel delivers 70 watts into 8 ohms (115 watts into 4 ohms), with all channels driven simultaneously—ensuring consistent performance across every output. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003eThis makes it well-suited for in-ceiling speakers, secondary listening zones, or height channels in immersive home theatre systems.\u003c\/p\u003e\n\u003cp data-start=\"719\" data-end=\"1115\"\u003eThe RMB-1504 is built around Rotel’s Class AB amplification and Balanced Design Concept, combining discrete output devices with a substantial power supply. At the centre is a custom toroidal transformer paired with high-efficiency capacitors, providing stable current delivery and reliable operation even across varying speaker loads and longer cable runs. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-start=\"1117\" data-end=\"1518\"\u003eWhat sets the RMB-1504 apart is its flexibility. It includes input linking for distributing a single source across multiple channels, along with front-panel attenuation controls for adjusting levels by zone. Signal sensing and 12V trigger connections allow for automatic power management, making it easy to integrate into larger systems or custom installations. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-start=\"1520\" data-end=\"1818\"\u003eThe amplifier is housed in a rack-friendly 3U chassis with included rack ears, allowing it to be easily installed in equipment racks or structured wiring systems.
