Getting Started

Thank you for purchasing the Rotel RB-1562 or RB-1572 Stereo Power Amplifier. 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. High current capability allows the RB-1562 and RB- 1572 to drive difficult speaker loads with ease.

The RB-1562 and RB-1572 are essentially identical units. They differ only in power output. In this manual the RB-1562 is most often depicted, but the RB-1572 operates in the same way.

Operating Features

•Two amplifier channels.

•User selectable power on/off configuration: manual or controlled by remote 12 volt trigger signal.

•Protection circuitry with front panel indicators.

•Dual binding post speaker outputs.

A Few Precautions

Please read this manual carefully. In addition to installation and operating instructions, it provides information on various system configurations. Please contact your authorized Rotel dealer for answers to any questions you might have. In addition, all of us at Rotel welcome your questions and comments.

Save the amplifier shipping carton and packing material for future use. Shipping or moving the amplifier in anything other than the original packing material may result in severe damage to your amplifier.

Be sure to keep the original sales receipt. It is your best record of the date of purchase, which you will need in the event warranty service is ever required.

Placement

The amplifier generates heat as part of its normal operation. The heat sinks and ventilation openings in the amplifier are designed to disperse this heat. The ventilation slots in the top cover must be unobstructed. There should be 10 cm (4 inches) of clearance around the chassis, and reasonable airflow through the installation location, to prevent the amplifier from overheating. Likewise, remember the weight of the amplifier when you select an installation location. Make sure that the shelf or cabinet can support its weight.

AC Power and Control

AC Power Input 7

The amplifier is supplied with the proper AC power cord. Use only this cord or an exact equivalent. Do not use an extension cord. A heavy duty multi-tap power outlet strip may be used, but only if it is rated to handle the current demand of the amplifier.

Be sure the Power Switch 1 on the front panel of the amplifier is turned off. Then, plug one end of the cord into the AC power connector 7 on the back panel of the amplifier. Plug the other end into an appropriate AC outlet.

Your amplifier is configured at the factory for the proper AC line voltage in the country where you purchased it (USA: 120 volts/60 Hz, Europe: 230 volts/50 Hz). The AC line configuration is noted on a label on the back panel.

Note: Should you move your amplifier to another country, it is possible to configure your amplifier for use on a different line voltage. Do not attempt to perform this conversion yourself. Opening the enclosure of the amplifier exposes you to dangerous voltages. Consult a qualified technician or the Rotel factory service department for information.

If you are going to be away from home for an extended period of time, it is a sensible precaution to unplug your amplifier.

Power Switch and Indicator 1

The Power Switch is located on the front panel. To turn the amplifier on (or to activate either of the optional automatic power-on modes), push the switch in. The ring around the switch will light, indicating that the amplifier is turned on. To turn the amplifier off, push the button again and return it to the out position.

Protection Indicator 2

Thermal protection circuits protect the amplifier against potential damage in the event of extreme or faulty operating conditions. Unlike many designs, the protection circuit of the RB-1562 and RB-1572

is independent of the audio signal and has no impact on sonic performance. Instead, the protection circuit monitors the temperature of the output devices and shuts down the amplifier if safe limits are exceeded.

In addition, the amplifiers includes over-current protection which operates only when load impedances drop too low. This protection is independent for each channel and is indicated by the front panel Protection LED.

Should a faulty condition arise, the amplifier channel at fault will stop playing and the Protection LED on the front panel will light.

If this happens, turn the amplifier off, let it cool down for several minutes, and attempt to identify and correct the problem. When you turn the amplifier back on, the protection circuit will automatically reset and the PROTECTION LED should go out.

In most cases, the protection circuitry activates because of a fault condition such as shorted speaker wires, or inadequate ventilation leading to an overheating condition. In very rare cases, highly reactive or extremely low impedance speaker loads could cause the protection circuit to engage.

Note: The Protection Mode LED also lights when the 12V Trigger system is being used and the amplifier is in Standby mode.
