User manual ROTEL RT-1220

[. . . ] 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. Keep this manual so you can refer to these safety instructions. [. . . ] For proper performance, you must maintain this polarity at all speaker connections. Always connect the positive terminal of each speaker to the corresponding red speaker terminal on the RT-1220 and the negative speaker terminal to the corresponding black connector on the RT-1220. Route the wires from the RT-1220 to the speakers. Leave enough slack so you can move the components to allow access to the speaker connectors. If you are using banana plugs, connect them to the wires and then plug them into the binding posts. The collars of the binding posts should be screwed in all the way (clockwise). If you are using terminal lugs, connect them to the wires. If you are attaching bare wires directly to the binding posts, separate the wire conductors and strip back the insulation from the end of each conductor. Be careful not to cut into the wire strands. Place the connector lug or the twisted bare wire through the hole in the binding post shaft. Turn the collars clockwise to clamp the connector lug or wire firmly in place. VCR See Figure 8 VCR connections can be made to the VIDEO 1 or VIDEO 2 inputs and outputs. When only one appears, that function is found only on the RT-1220 or the remote. The display can be turned off, if desired. See the DISP button section for instructions. Remote Sensor This sensor receives IR signals from the remote control. Do not block this sensor unless an external IR receiver is used. STANDBY Button POWER Switch The front panel STANDBY button activates or deactivates the unit. The rear panel master POWER switch must be in the ON position for the standby function to operate. ON/OFF Buttons The power ON and OFF buttons on the remote provide discrete ON/OFF commands which duplicate the function of the front panel STANDBY button. Press the ON button to activate the unit; press the OFF button to put the unit into standby mode. The rear panel master POWER switch must be in the ON position for the standby function to operate. Layout of Controls, Buttons, and Features The following is a brief overview of the controls, buttons, and features of the RT-1220. Details concerning the use of these controls are provided in subsequent sections of this manual describing various operations. VOLUME Knob VOLUME Buttons The large rotary control on the front panel and the pair of VOLUME buttons on the remote provide the master VOLUME control, adjusting the output level of all channels simultaneously. MUTE Button Push the MUTE button on the remote once to turn the sound off. An indication appears in the front panel. Press the button again to restore previous volume levels. RR-AT93 Remote Control The RT-1220 includes a remote control that operates the RT-1220. The RR-AT93 is also preprogrammed to operate many Rotel CD and DVD players. Pressing the volume buttons on the remote also cancels the muting function. NOTE: Front-panel Display The display on the front panel of the RT-1220 provides information about the status of the unit, tuner reception, and special features. The main portion of the display typically shows the current input source (or radio station frequency). [. . . ] When linked, changing the input in the main room will automatically change it in the remote zone, too. Troubleshooting The unit does not turn on. · Make sure the power cord is plugged into the rear panel and a live AC wall outlet. · Make sure the rear panel POWER switch is in the ON position. · Make sure that MUTING is off and VOLUME is turned up.
