[. . . ] WARNING: To reduce the risk of fire or electric shock, do not expose the unit to moisture or water. 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. Read all the instructions before connecting or operating the component. [. . . ] Twelve-channel power amplifier, with 100 watts per channel ouput into 8ohm Front panel input level control User-selectable power on/off configuration: manual, automatic signal sensing, or controlled by remote 12 volt trigger signal. Protection circuitry against fault conditions with front panel indicators. To turn the amplifier on (or to activate either of the optional automatic poweron modes), push the switch in. The indicator light 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. In addition to basic installation and operating instructions, it provides valuable information on various RMB-1512 system configurations as well as general information that will help you get optimum performance from your system. 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 RMB-1512 shipping carton and all enclosed packing material for future use. Shipping or moving the RMB-1512 in anything other than the original packing material may result in severe damage to your amplifier. Fill out and send in the owner's registration card packed with the RMB-1512. It is your best record of the date of purchase, which you will need in the event warranty service is ever required. The RMB-1512 provides three different options for manual or automatic power on/off operation. These modes are selectable using a three-position slide switch on the back panel as follows: · With the switch in the OFF position, the amplifier is turned on or off manually using the front panel power switch. Also use this mode if you are using a switched AC outlet to control power to the amplifier. With the switch in the SIGNAL SENSE POSITION, the amplifier turns on automatically when a signal is detected at the inputs. The amplifier will go into standby mode several minutes after no signal is no longer present. Turning the switch OFF cuts power to the amplifier, regardless of whether or not a signal is present. With the switch in the 12V TRIG position, the amplifier is turned on automatically when a 12 volt trigger signal is present at the 12V TRIG input to the left of the switch. The amplifier goes into standby mode if the +12 volt signal is not present. Turning the switch OFF cuts power to the amplifier, regardless of whether or not a trigger signal is present. Place the RMB-1512 on a solid, level surface away from sunlight, heat, moisture, or vibration. Likewise, remember the weight of the amplifier when you select an installation location. [. . . ] The polarity or positive/negative orientation of the connections for every speaker and amplifier connection must be consistent so all the speakers will be in phase. if the polarity of one connection is mistakenly reversed , bass output will be very weak and stereo imaging degraded. The wire may have clear insulation with different color conductors (copper and silver). Give yourself enough slack so you can move the components to allow access to the speaker connectors. [. . . ]
