BEFORE USING
Pay attention to the following before using this unit:
• Moving the set
To prevent short circuits or damaged wires in the
connection cords, always unplug the power cord and
disconnect the connection cords between all other
audio components when moving the set.
• Before turning the power operation switch on
Check once again that all connections are proper and
that there are not problems with the connection cords.
Always set the power operation switch to the
standby position before connecting and disconnecting
connection cords.
• Store this instructions in a safe place.
After reading, store this instructions along with the
warranty in a safe place.
• Note that the illustrations in this instructions may
differ from the actual set for explanation purposes.
• V. AUX terminal
The AVR-1803's front
panel is equipped with a
V. AUX terminal. Remove
the cap covering the
terminal when you want
to use it.
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.
• 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 jack, 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
operation 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 operation switch is in the
£ OFF or 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.
1. Dolby Pro Logic II decoder
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.
2. Dolby Digital decoder
Dolby Digital, a digital discrete system in which the
different channels are completely independent,
recreates “three-dimensional” sound fields (sounds
with a sense of distance, movement and position)
with no crosstalk between channels for greater
reality. In addition, the 5 channels (excluding the 0.1
channel for low frequency effects) have a playback
range extending to 20 kHz, the same as the range
of CDs, thus resulting in clearer, more richly
expressive sound.
3. DTS (Digital Theater Systems) decoder
DTS provides up to 5.1 channels of wide-range, high
fidelity surround sound, from sources such as laser
disc, DVD and specially-encoded music discs.
4. DTS-ES Extended Surround and DTS Neo:6
The AVR-1803 is compatible with DTS-ES
Extended Surround, a new multi-channel format
developed by Digital Theater Systems Inc.
The AVR-1803 is also compatible with DTS Neo:6,
a surround mode allowing 6.1-channel playback of
regular stereo sources.
5. Component Video Switching
In addition to composite video and “S” video
switching, the AVR-1803 provides 2 sets of
component video (Y, P
B/CB, PR/CR) inputs
assignable, and one set of component video
outputs to the television, for superior picture
quality.
6. Auto Surround Mode
This function stores the surround mode last used
for an input signal in the memory and automatically
sets that surround mode the next time that signal is
input.
