FEATURES
• 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 MASTER VOLUME control or connect components
to the input jacks.
• Muting of PRE OUT jacks, HEADPHONE jack and SPEAKER
terminals
The PRE OUT jack, HEADPHONE jack and SPEAKER terminals
include a muting circuit. Because of this, the output signals are
greatly reduced for several seconds after the power switch is
turned on or input function, surround mode or any other-set-up is
changed. 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 switch is in the STANDBY state, the
apparatus is still connected on AC line voltage.
Please be sure to unplug the cord when you leave home for,
say, a vacation.

Dolby Pro Logic II is a new format for playing multichannel audio
signals that offers improvements over conventional Dolby Pro
Logic. It can be used to decode not only sources recorded in Dolby
Surround but also regular stereo sources into five channels (front
left/right, center and surround left/right). In addition, various
parameters can be set according to the type of source and the
contents, so you can adjust the sound field with greater precision.

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.
