User manual ROTEL RMB-100

[. . . ] Do not place objects filled with liquids, such as vases, on the unit. Do not allow foreign objects to get into the enclosure. If the unit is exposed to moisture, or a foreign object gets into the enclosure, immediately disconnect the power cord from the wall. Take the unit to a qualified service person for inspection and necessary repairs. [. . . ] Rotel has chosen to specify the power output in this way because, in Rotel's experience, it gives the truest value of the receiver or amplifier's power capability. When comparing specifications for different products, you should be aware that power output is often specified in other ways, so you may not be comparing like with like. For example, the power output may be quoted with only one channel operating, giving a higher maximum figure. The highly regulated power supplies of the Rotel Class D amplifiers ensures that they will produce the full specified power output to one or all channels. A loudspeaker's impedance rating indicates the electrical resistance or load it offers when connected to the amplifier, usually 8 ohms or 4 ohms. The lower the impedance, the more power the speaker will need. In effect, a 4 ohm speaker will require twice as much power as an 8 ohm speaker. So ideally, the amplifier should be give double the power into a 4 ohm load ­ a rating of 100 watts into an 8 ohm load should become 200 watts into 4 ohms. Using lower impedance speakers makes greater demands on the amplifier's power supply, because it will be drawing more current and giving off more heat. Over the decades, we have received hundreds of awards for our products and satisfied hundreds of thousands of people who take their entertainment seriously - like you!Rotel was founded by a family whose passionate interest in music led them to manufacture high-fidelity components of uncompromising quality. Consult a qualified technician or the Rotel factory service department for information. Plug the supplied cord into the AC INPUT receptacle 7 on the back panel of the unit. After all connections have been made, plug the other end into an appropriate AC wall outlet. Note: If you are going to be away from home for an extended period of time, it is a sensible precaution to unplug your amplifier. 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. To turn the amplifier on (or to activate either of the optional automatic power-on modes), push the switch in. [. . . ] in general , heavier wire will improve the sound. For best performance, you may want to consider special high-quality speaker cables. Your authorized Rotel dealer can help in the selection of appropriate cables for your system. Thermal and protection circuits protect the amplifier against potential damage in the event of extreme or faulty operating conditions. [. . . ]
