Operation

For true two-channel stereo operation, press
the 

button 



or use the

î

on the remote

until 

STEREO

appears briefly in the

¯

to use only the

front left and right speakers.

Note that if no Center speaker is connected,
the ”Dolby 3 Stereo” mode shouldn’t be
used as the Center information will be lost
in that case.

• The AVR18 RDS is equipped with a
memory system that permits a different
surround mode to be used with each of the
input sources. You may select the mode that
is most appropriate to each source, such as
Pro Logic for a VCR or DVD player
connected to a Video input, Hall for the CD
input and Surround Off for the Tuner. When
you select an input again for a subsequent
listening session the system will
automatically change to your preferred
surround mode for that input.

• To check the current surround mode at
any time, press either 

r

î

NOTE: Once a program has been encoded
with surround information, it retains the
surround matrix as long as the program is
broadcast in stereo. Thus, movies with
surround sound will carry surround
information when they are broadcast via
conventional TV stations, cable, pay TV and
satellite transmission. In addition, a
growing number of made-for-television
programs, sports broadcasts, radio dramas
and music CDs are also recorded in
surround sound. You may obtain a list of
these programs and discs from the Dolby
Laboratories web site at www.dolby.com

When a program is not listed as carrying
intentional surround information, you may
find that Pro Logic or Dolby 3-Stereo modes
often deliver enveloping surround
presentations through the use of the natural
information present in all stereo recordings.
However, for stereo, but non-surround
programs, we suggest that you try the Hall
1, Hall 2 or Theater modes.

The AVR18 RDS is a digital-ready receiver,
which means that it is equipped for use
with optional, external digital audio
decoders. This enables the AVR18 RDS to
serve you well into the future, through
connecting to a decoder for formats such
as Dolby Digital or DTS.

You may also use these inputs for direct
connection to DVD players or digital
television sets that have built-in decoding
for Dolby Digital. When one of these
products is used, no external adapter or
decoder is needed.

For 6-channel direct operation, connect
the outputs of the decoder or other devices
with decoded digital outputs to the
appropriate 

°

on the rear panel, making shure to

match channels.

To listen to the 6-channel source, press the

@ ∂

button on the front panel or remote. A red
LED will light above the Front selector
button 

@

to indicate, that the formerly

selected source remains routed to the
record outputs. After some seconds the
formerly selected video source, fed through
to the TV monitor output, will be indicated
in the information display, f.e. V IN: DVD.
Pressing the 

button 

@ ∂

again will return

to the former input selection.

NOTE: Since the 6-channel input is a
discrete source, the Surround mode
selectors do not function when a 6-
channel direct input is used. In addition,
the record outputs may not be used when a
6-channel source is playing.

The AVR18 RDS may be connected to
optional, external amplifiers for
applications when higher power output is
desired. These outputs may also be used to
send the same source being listened to
through the AVR18 RDS’s built-in
amplifier to a second location.

To connect an external amplifier, simply
connect the Preamp Outputs 

¢

on the

rear panel to the inputs of an optional,
external power amplifier.

No special adjustments are required when
an external power amplifier is in use. All
volume and output adjustments are made
using the standard controls.

The AVR18 RDS’s tuner is capable of
tuning AM(MW), FM and FM Stereo
broadcast stations. Stations may be tuned
manually, automatically or they may be
stored as favorite station presets and
recalled from a 30-position memory.
