User manual ROTEL RA-985BX

[. . . ] WARNING: There are no user serviceable parts inside. refer all servicing to qualified service personnel. WARNING: To reduce the risk of fire or electrical shock, do not expose the unit to moisture or water. Do not allow foreign objects to get into the enclosure. [. . . ] typically that will be a conventional tape recorder. When connecting a recorder to the RA-985BX remember that the outputs of the recorder must be connected to the tape inputs of the RA-985BX. similarly the tape outputs of the RA-985BX must be connected to the inputs of the recorder. As with other sources be sure to connect the Left and Right channels of each device to the proper channels on the associated components. Use high quality connecting cables to prevent loss of sound quality. ] The RA-985BX has conventional RCA type input connectors, the type found on nearly all audio equipment. North American models of the RA-985BX have two switched outlets on the back panel. Power is available from these outlets when the RA-985BX is turned on. Power to these outlets is turned off when the RA-985BX is in Standby mode. These outlets can provide up to a total of 400 watts. They are appropriate for supplying power to signal sources, such as CD players, tuners, or tape decks. They should not be used for power amplifiers. Connecting components that will draw more than 400 watts to these outputs could damage the Standby switch in the RA-985BX. However when the Second Zone output function is used, the Recording Selector becomes the source selector for the Second Zone. ] This output (when used with an additional power amplifier and speakers) lets the RA-985BX provide sound to another part of your home. You can listen to a different signal source from the one being played by the main system or to the same source. These connectors, labeled "Pre Out" and "Main In", are normally connected by a set of solid metal jumper connectors. They provide a convenient insertion point for virtually any type of signal processor. To use these connectors, pull out the jumper connectors. One of the most common uses for these connectors is to incorporate a surround sound processor into the system. in general , heavier wire will improve the sound. For best performance, you may want to consider special high-quality speaker cables. [. . . ] the protection circuits are independent of the audio signal and have no impact on sonic performance. Instead, the protection circuits monitor the temperature of the output devices and shut down the amplifier if temperatures exceed safe limits. Most likely, you will never see this protection circuitry in action. However, should a faulty condition arise, the amplifier will stop playing and the LED indicator on the front panel will light up.
