2 CAUTIONS ON INSTALLATION Noise or disturbance of the picture may be generated if this unit or any other electronic equipment using microprocessors is used near a tuner or TV. If this happens, take the following steps: • Install this unit as far as possible from the tuner or TV. • Set the antenna wires from the tuner or TV away from this unit's power cord and input/output connection cords. • Noise or disturbance tends to occur particularly when using indoor antennas or 300 Ω/ohms feeder wires. We recommend using outdoor antennas and 75 Ω/ohms coaxial cables. For heat dispersal, leave at least 10 cm of space between the top, back and sides of this unit and the wall or other components. ENGLISH 10 cm or more B 10 cm or more Wall 3 CAUTIONS ON HANDLING • Switching the input function when input jacks are not connected A clicking noise may be produced if the input function is switched when nothing is connected to the input jacks. If this happens, either turn down the VOLUME control or connect components to the input jacks. • Muting of PRE OUT jacks The PRE OUT jacks include a muting circuit. Because of this, the output signals are greatly reduced for several seconds after the power operation switch is turned on. If the volume is turned up during this time, the output will be very high after the muting circuit stops functioning. Always wait until the muting circuit turns off before adjusting the volume. • Whenever the power operation switch is in the STANDBY state, the apparatus is still connected on some AC line voltages. Please be sure to unplug the cord when you leave home for, say, a vacation. 4 FEATURES 1. Multi Room Music Entertainment System Multi Source Function: This unit's Multi Source function lets you select different audio or video sources for viewing or listening Different sources can thus be enjoyed in the main room and the subroom simultaneously. This novel feature gives you considerable flexibility when setting up and enjoying your system with the this unit. The output level, adjustable by the remote commander, is as much as 1V, enough to operate the optional power amplifier placed in a subroom. 2. Powerful, Versatile Amplifier High-Quality Power Amplifier: High-speed, high-power transistors employed in a rational circuit configuration reflect DENON'S advanced amplifier technology and ensure a very hefty, clean power output. 3. Signal Level Divided Construction (SLDC) The circuits handling low-level and high-level signals have been divided into separate blocks to ensure that influences from these signals on each other are held to an absolute minimum. This chassis design in the this unit is called the Signal Level Divided Construction (SLDC). Signals for output are cleaner than before, allowing them to be reproduced with even greater fidelity and clarity. 4. Remote Control Functions • Remote Control unit with pre-memory function (RC-872): This unit comes with a remote control unit equipped with a pre-memory function. The remote control command codes for DENON remote controllable AV components as well as for DVD players, video decks, TVs, etc., of other major manufacturers are prestored in the memory. • Multi Source Remote Control Unit (RC-873): This unit comes with the Multi Source Remote Control Unit, which operates the Multi Source Output and commands the receiver to select the function, recalling preset stations, and adjust the volume level from a subroom. 5
