User manual ROTEL RC-850

[. . . ] 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. [. . . ] Shipping or moving the RC-850 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 RC-850. Also 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. RC-850 Stereo Control Amplifier 6 Placement Like all audio components that handle low-level signals, the RC-850 can be affected by its environment. Do not stack the RC-850 on top of a power amplifier. This will minimize chance it will pick up hum or interference. We recommend installing the RC-850 in furniture designed to house audio components. Such furniture is designed to reduce or suppress vibration which can adversely affect sound quality. Ask your authorized Rotel dealer for advice about component furniture and proper installation of audio components. Remote Sensor 3 The Remote Sensor is located to the right of the Phones jack on the front panel. It picks up the infra-red signals from the remote control. It must be clear of obstructions or the remote control will not work properly. See the "Controlling Other Components" section of this manual for more information. Most of the RR-AT97 functions duplicate the front panel controls. In this manual the remote control functions are covered in the same section as the front panel control operation. Numbers in gray boxes such as 1 indicate items on the front and rear panel control and connection illustrations. Letters in gray circles such as A indicate items on the RR-AT97 illustration. See Figure 2 on page 3. Input Signal Connections e and r [See Figure 3. ] The RC-850 has conventional RCA-type connectors for all inputs. NOTE: To prevent loud noises that neither you nor your speakers will appreciate, make sure the system is turned off when you make any signal connections. Line Level Inputs r The CD, Tuner, and Aux inputs of the RC-850 are "line level" inputs. NOTE: The EXT REM IN jack located next to these jacks is for use with an external IR sensor duplicating the front panel IR sensor and located in the primary zone. 12 Volt Trigger Outlet p 12V Trigger Connections p Many Rotel amplifiers offer the option of turning them on and off using a 12 volt trigger signal sent to them. The RC-850 provides two 12 volt trigger outputs. When the RC-850 is turned on, a 12 volt DC signal is sent to the amplifiers to turn them on. When the RC-850 is put in STANDBY mode, the trigger signal is interrupted and the amplifiers turn off. [. . . ] Turning the control clockwise shifts the sound balance to the right. Balance Control 7 When the Tone Switch is in the Off (out) position the Bass and Treble Control circuits are bypassed to ensure the purest possible sound. Leave the Tone Switch in the Off position unless you want to use the Tone Controls. Push in the Tone Switch if you want to adjust the Tone Controls. Tone On/Off Switch 6 Controlling Other Components In addition to operating many of the controls of the RC-850, the RR-AT97 remote control can operate basic features of some Rotel CD players, DVD players, and AM/FM tuners. When the Tone Switch is pushed in, turning the Bass and Treble Controls adjusts the tone balance of the sound. Turn the Controls clockwise to increase the bass or treble output. [. . . ]
