User manual ROTEL RT-870

[. . . ] Do not allow foreign objects to get into the enclosure. 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. [. . . ] Then, connect the VIDEO 2 composite video output to the video input of the same source component. Repeat these steps for VIDEO 3 and VIDEO 4 connections. To avoid mistakes, make sure that you: Main Processor RCA Audio Outputs 18 [See Figure 3] The RT-870 sends six channels of audio to the power amplifiers. These outputs (6 individual RCA-style jacks) direct the RT-870's main output to power amplifiers for speakers in the primary listening/viewing area. These six outputs (Left Front, Center Front, Right Front, Left Surround, Right Surround, and Subwoofer) connect the RT-870's main audio output to a multichannel power amplifier or multiple power amplifiers for the primary listening area. Standard color coding applies with black insets to distinguish Center Channel and Subwoofer outputs from Left (white) and Right (red) Front and Rear outputs. To hook up the RCA main audio outputs, connect a standard audio cable from each output to the input of the amplifier channel that will power the corresponding speaker. In a full home theater system, you will need to make six different connections corresponding to the six speakers (Left Front, Center Front, Right Front, Left Surround, Right Surround, and Subwoofer). It is important to make sure that you have the correct output connected to the proper amplifier channel. Take your time and you will have no trouble getting it right. · Connect the source component's outputs to the appropriate RT-870 inputs Connect the appropriate RT-870 outputs to the source component inputs. Make sure that whatever video component is connected to the VIDEO 2 inputs is the same component connected to the VIDEO 2 outputs, etc. · · Note 1: The signal available at these outputs is determined by the RECORDING input selection buttons and is not necessarily the same source as that selected by the LISTENING input selection buttons. This is the only way to have a "mixed" system with some RCA composite and some S-Video sources. Tape Monitor Audio Outputs 14 [See Figure 4] A pair of RCA-type audio outputs send a signal to an audio recording device (cassette deck, DAT, or Mini-Disc recorder, etc. ). The analog signal from any of your source components will be routed to these outputs for recording, depending on the selection made with the LISTENING input buttons. Connect audio cables from the RT-870's TAPE MONITOR OUT jacks to your recorder's analog inputs. Note: Only analog input signals are routed to the TAPE MONITOR OUT jacks. If you are using a digital input, you should also connect the analog output of the source component for recording. Rear Panel AC Power Connections AC power 21 Your RT-870 is configured at the factory for the proper AC line voltage in the country where you purchased it (115 volts/60Hz AC in the USA and 230 volts/50Hz AC in Europe). The AC line configuration is noted on the back of your unit. Plug the supplied power cable into the AC receptacle on the back of the unit. Then, plug into an appropriate AC outlet. · An infrared repeater system (Xantech, Niles, et al) should be used for Zone 2 control via the 3. 5 mm REMOTE EXTENSION IN jack on the back panel Zone 2 is immediately active when the RT-870 is turned on, either at a zero volume level or at the last previous volume depending on the "Zone 2 Auto-Mute" setting chosen from the ON-SCREEN MENU system during initial system setup. By default, Auto-Mute is engaged, meaning that every time you turn the unit off, the volume in the remote zone is muted and must be manually raised the next time Zone 2 is used. If Auto-Mute is not engaged, the remote zone will begin playing at the previous volume the next time the RT-870 is activated. The RR-939 remote control supplied with the RT-870 will operate Zone 2 if used in conjunction with a repeater system from the remote zone. It can also be programmed to operate Rotel source components via the RT-870's REMOTE EXTENSION OUT jack. · · 17 SURROUND SOUND PROCESSOR RT-870 · All source components connected to the RT-870's analog audio inputs (except the TAPE MONITOR and 5. 1 CHANNEL input) are available at the line level output for Zone 2. [. . . ] LFE MIX LEVEL: This setting determines the relative signal level of the LFE (Low Frequency Extension) channel (the . 1 channel) relative to the five full-range channels. It is factory set according to the standards of Dolby Labs, DTS Technology, and THX Lucasfilm. The adjustment may be varied for each surround mode according to personal taste, if desired. The LFE content of DTS encoded movies is mixed differently than DTS encoded music. [. . . ]
