Advanced Features

In addition to basic audio functions,
this receiver is capable of audio/video
dubbing and a wide range of surround
modes. Advanced digital decoding and
signal processing provides specialized
surround modes that are compatible with
virtually all types of music software and
movie soundtracks.

The input directed to the audio and video
record outputs 

£ ∞ e h

is normally

the source currently selected for listening
through the AVR75. If you are using a
tape recorder or cassette deck with three
heads and wish to listen to the “off tape”
playback to verify the recording, press the
front panel

button 

5

or the

d

button on the remote until

the red light over

on the front

panel illuminates. You will then hear the
source as it is being recorded and played
back through your tape machine. The
source will be verified in both the front
panel and on-screen displays. Note that
the video surrounding the word

AUDIO

will turn white to indicate that you are in
the Tape Monitor mode.

It is possible to watch and listen to, or
record the video from one source along
with the audio from a different input.
This is useful in the case of musical pro-
grams where the sound is being broadcast
via FM, or for sports events where you
wish to have the picture from a TV sta-
tion, but the play-by-play from a radio
station.

For simulcast operation first select the
video source input using the input selec-
tion buttons on the remote control or
front panel

8)!d

. Next, select the

audio source 

2457d

. Note that

the on-screen menu display will show the

split sources (see figure #7). The front
panel display will show the audio source
in large letters in the main portion of the

J

, while the

video source will appear in smaller letters
next to the

indicator 

P

.

With the increasing sophistication of
today’s home entertainment systems, it
often takes numerous remote controls to
turn on all components in a system. This
receiver’s unique “TV Auto On” function
greatly simplifies that task and reduces
the actions needed to bring your entire
system to life.

If you are using a TV or projector that has
a video output, connect the TV’s audio
and video outputs to the rear panel of the
AVR75

ª

. Once those connections have

been made and the feature is turned on,
the AVR75 will automatically turn on
whenever the TV set is on, thanks to a
video-sensing circuit in the AVR75. This
eliminates the need to turn the unit on
separately from the TV.

As long as the TV is on and feeding a
video signal, the AVR75 will remain on. 
If no other input source is selected and
the TV is turned off, the AVR75 will turn
off approximately five minutes after the
TV set.

This feature is turned off in the AVR75’s
factory configuration and must be turned
on using the following steps:

1. Press the front panel 

⁄

button 

@

.

2. While holding the Mode button, press
the 

button 

8

for at least 5 seconds

until the 

J

display reads 

TV AT OFF

.

3. Release both buttons and immediately
press the 

button 

8

again until the

display reads 

TV AT ON

.

If you select another input, such as CD 
or the AM/FM tuner after the unit has 
turned on, it will remain on even if the 
TV is turned off. You must then turn the
receiver off using the front panel or
remote 

buttons 

1c

.

NOTE: The TV Auto On Function will only
respond to conventional video signals. It
will NOT operate with S-Video.

If, at some future point you wish to dis-
able this feature, follow the steps outlined
above but press the 

button 

8

as

shown in step #3 so that the display reads

TV AT OFF

.

One aspect of the surround modes is the
delay of audio signals between the front
speakers and the rear speakers. Each
surround mode is factory preset with a
specific delay time, but it is possible to
individually adjust the delay timing to
custom tailor the sound to your individ-
ual taste and the acoustic conditions in
your listening room or home theater.

The factory setting is appropriate for
most rooms, but some installations
create an uncommon distance between
the front and surround speakers that may
cause the arrival of front channel sounds
to become disconnected from surround
channel sounds.

To resynchronize the front and surround
channels, follow these steps:

1. Measure the distance from the
listening/viewing position to the
front speakers.

2. Measure the distance from the
listening/viewing position to the
surround speakers.
