User manual ROTEL RT-870

[. . . ] Take the unit to a qualified service person for inspection and necessary repairs. Read all the instructions before connecting or operating the component. Heed all warnings and safety information in these instructions and on the product itself. You must allow 10 cm or 4 inches of unobstructed clearance around the unit. [. . . ] For convenience, each topic begins with an overview of the particular connection, followed by detailed hookup instructions. 13 [See Figure 4] These three sets of RCA outputs (VIDEO 2, VIDEO 3, and VIDEO 4) include left and right channel audio plus composite video outputs from the RT-870 to appropriate components (VCR, etc. ) for recording or further processing. Connect the RT-870's VIDEO 2 left and right audio outputs to the audio inputs of the first source component. Then, connect the VIDEO 2 composite video output to the video input of the same source component. 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. 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. You can select a different source or adjust Zone 2 volume without effecting the MAIN outputs in any way. Avoid sending the same infrared command to the RT-870 front panel sensor and the Zone 2 repeater at the same time. This means that Zone 2 must be in a different room from the RT-870. Remote External Sensor/Repeater Jacks 20 [See Figure 6] These 3. 5 mm mini-jacks allow your RT-870 to send/receive command codes from industry-standard infrared transmitters and receivers via hard-wired connections. They are used in configuring your RT-870 with the proper IR connections for Zone 2 operation. These 3. 5 mm mini-jack connections provide easy incorporation of third party infrared transmitters and repeaters (Xantech, etc. ) for total control of custom installed and multi-zone systems. [. . . ] An instruction menu appears and a low frequency noise signal is sent to the subwoofer (or LARGE speakers if no subwoofer is present). Adjust the noise level with the VOL buttons until you just begin to hear distortion from the speakers. STEREO/P/L SW: This setting allows you to override the standard bass management in STEREO, PRO LOGIC, and DSP MUSIC modes when LARGE front speakers are selected. Select YES to have a subwoofer active with LARGE front speakers in these modes. [. . . ]
