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 /ohms feeder wires. We recommend using
outdoor antennas and 75 /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 compo-
nents.

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.

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.
B
• 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. 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.
