User manual ROTEL RKB-2100

[. . . ] Rotel products are designed to comply with international directives on the Restriction of Hazardous Substances (RoHS) in electrical and electronic equipment and the disposal of Waste Electrical and Electronic Equipment (WEEE). The crossed wheelie bin symbol indicates compliance and that the products must be appropriately recycled or processed in accordance with these directives. This symbol means that this unit is double insulated. An earth or ground connection is not required. [. . . ] Save the RKB-2100 shipping carton and all enclosed packing material for future use. Shipping or moving the RKB-2100 in anything other than the original packing material may result in severe damage to your amplifier. It is your best record of the date of purchase, which you will need in the event warranty service is ever required. However, when rack mounting or otherwise installing the amplifier in a confined space near other heat-generating components, additional cooling may be desirable. The optional RKBF1 fan kit can be easily installed for additional forced air cooling. In addition to lowering operating temperatures, the optional fan kit improves the performance of the amplifier, especially when driving difficult loudspeaker loads. When not using an equipment rack, place the RKB-2100 on a solid, level surface away from sunlight, heat, moisture, or vibration. When using the fan cooling, select a location for the amplifier where the noise will not be intrusive. Your RKB-2100 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. The RKB-2100 is supplied with the proper AC power cord. Use only this cord or an exact equivalent. Be sure the power switch on the front panel of the RKB-2100 is turned off. Then, plug one end of the cord into the AC power connector on the back panel of the amplifier. Plug the other end into an appropriate AC outlet. If you are going to be away from home for an extended period of time, it is a sensible precaution to unplug your 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. The front panel power switch overrides this function. it must be ON for the signal sensing to work. 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. [. . . ] If you encounter problems, isolate the area of the difficulty, check the control settings, determine the cause of the fault and make the necessary changes. If you are unable to get sound from the RKB-2100, refer to the suggestions for the following conditions: 03% THD) 100 watts/ch into 8 ohms, all channels driven Continuous Power Output into 4 ohms (DIN 1 kHz, 1. When sizing openings in custom cabinets, measure the unit to be installed and/or allow at least 1 mm clearance on all sides for unit to unit tolerances. all specifications are accurate at the time of printing.
