And, as more and more electronics are produced and later discarded, it is especially important for a manufacturer to do all it can to engineer products that have a minimum negative impact on landfill sites and water tables. When used in a high-quality music or home theater system, your Rotel amplifier will provide years of musical enjoyment. The RB-1562 and RB-1572 are sophisticated two-channel power amplifiers. Their Class D amplifier circuitry, switching power supply, premium components, and Rotel's Balanced Design ensure superb sound quality.

Opening the enclosure of the amplifier exposes you to dangerous voltages. Consult a qualified technician or the Rotel factory service department for information.
