Yamaha DSP -A780 Stereo Amplifier User Manual


 
When you notice that remote control operation has become
erratic, or the distance from which the remote control will function
has decreased, it’s time to replace the batteries. Always replace
all batteries at the same time.
This remote control uses an advanced, highly directional infrared
beam. Be sure to aim the remote control directly at the remote
control sensor on the main unit when operating.
Remote control transmitter operation range
Notes
There should be no large obstacles between the remote
control transmitter and the main unit.
If the remote control sensor is directly illuminated by strong
lighting (especially an inverter type of fluorescent lamp etc.),
it might cause the remote control transmitter to work
incorrectly. In this case, reposition the main unit to avoid
direct lighting.
Digital Sound Field Processing
What is it that makes live music so good? Today’s advanced
sound reproduction technology lets you get extremely close to the
sound of a live performance, but chances are you’ll still notice
something missing, the acoustic environment of the live concert hall.
Extensive research into the exact nature of the sonic reflections that
create the ambience of a large hall has made it possible for Yamaha
engineers to bring you this same sound in your own listening room,
so you’ll feel all the sound of a live concert. What’s more, our
technicians, armed with sophisticated measuring equipment, have
even made it possible to capture the acoustics of a variety of actual
concert halls, jazz clubs, theaters, etc. from around the world, to
allow you to accurately recreate any one of these live performance
environments, all in your own home.
Dolby Pro Logic Surround
The Dolby Pro Logic Surround Decoder program lets you
experience the dramatic realism and impact of Dolby Surround movie
theater sound in your own home. Dolby Pro Logic gets its name from
its professional-grade steering logic circuitry, which provides greater
effective channel separation for a much higher degree of realism than
the “passive” Dolby Surround circuits found in today’s typical home
audio/video equipment. Dolby Pro Logic Surround provides a true
center channel, so that there are four independent channels, unlike
passive Dolby Surround, which has in effect only three channels: left,
right, and rear. This center channel allows listeners seated in even
less-than-ideal positions to hear the dialog originating from the action
on the screen while experiencing good stereo imaging.
