Problem
FM
AM
Cause
The characteristics of FM stereo
broadcasts may cause this problem
when the transmitter is too far away or
the antenna input is poor.
There is multipath interference.
The station is too weak.
This unit has been disconnected for a
long period.
The signal is weak or the antenna
connections are loose.
Noises result from lightning,
fluorescent lamps, motors, thermostats
and other electrical equipment.
A TV set is being used nearby.
Remedy
Check the antenna connections.
Try using a high-quality directional FM
antenna.
Use the manual tuning method.
Adjust the antenna position to eliminate
multipath interference.
Use a high-quality directional FM antenna.
Use the manual tuning method.
Re-store the stations.
Tighten the AM loop antenna connections
and orient it for best reception.
Use the manual tuning method.
Use an outdoor antenna and a ground wire.
This will help somewhat, but it is difficult to
eliminate all noise.

GLOSSARY
Dolby Surround
Dolby Surround uses a 4 channel analog recording system
to reproduce realistic and dynamic sound effects: 2 main
left and right channels (stereo), a center channel for
dialog (monaural), and a rear channel for special sound
effects (monaural). The rear channel reproduces sound
within a narrow frequency range.
Dolby Surround is widely used with nearly all video tapes
and laser discs, and in many TV and cable broadcasts as
well. The Dolby Pro Logic decoder built into this unit
employs a digital signal processing system that
automatically stabilizes the volume on each channel to
enhance moving sound effects and directionality.
Dolby Digital
Dolby Digital is a digital surround sound system that
gives you completely independent multi-channel audio.
With 3 front channels (left, center, and right), and 2 rear
stereo channels, Dolby Digital provides 5 full-range audio
channels. With an additional channel especially for bass
effects, called LFE (low frequency effect), the system has
a total of 5.1 channels (LFE is counted as 0.1 channel).
By using 2-channel stereo for the rear speakers, more
accurate moving sound effects and surround sound
environment are possible than with Dolby Surround. The
wide dynamic range (from maximum to minimum
volume) reproduced by the 5 full-range channels and the
precise sound orientation generated using digital sound
processing provide listeners with previously unheard of
excitement and realism.
With this unit, any sound environment from monaural up
to a 5.1-channel configuration can be freely selected for
your enjoyment.
Matrix 6.1
The unit incorporates Matrix 6.1 decoder for Dolby
Digital and DTS multi-channel software that enables 6.1-
channel reproduction by adding the rear center channel to
existing 5.1-channel format. (The rear center channel is
created from rear left and right channels, and outputted
from virtual rear center speaker.) With this additional
channel, you can experience more dynamic and realistic
moving sound especially with scenes with “fly-over ” and
“fly-around ” effects.
Dolby Pro Logic 
Dolby Pro Logic  is an improved technique used to
decode vast numbers of existing Dolby Surround
softwares. This new technology enables a discrete 5-
channel playback with 2 main left and right channels, 1
center channel, and 2 rear left and right channels (instead
of only 1 rear channel for conventional Pro Logic
technology). A music mode is also available for 2-channel
sources in addition to the movie mode.
DTS (Digital Theater Systems)
Digital Surround
DTS digital surround was developed to replace the analog
soundtracks of movies with a 6-channel digital sound
track, and is now rapidly gaining popularity in movie
theaters around the world. Digital Theater Systems Inc.
has developed a home theater system so that you can
enjoy the depth of sound and natural spatial
representation of DTS digital surround in your home.
This system produces practically distortion-free 6-channel
sound (technically, a left, right and center channels, 2 rear
channels, plus an LFE 0.1 channel as a subwoofer, for a
total of 5.1 channels).
LFE 0.1 channel
This channel is for the reproduction of low bass signals.
The frequency range for this channel is 20 Hz to 120 Hz.
This channel is counted as 0.1 because it only enforces a
low frequency range compared to the full-range
reproduced by the other 5 channels in a Dolby Digital or
DTS 5.1 channel systems.
CINEMA DSP DIGITAL
Since the Dolby Surround and DTS systems were
originally designed for use in movie theaters, their effect
is best felt in a theater having many speakers and
designed for acoustic effects. Since home conditions,
such as room size, wall material, number of speakers, and
so on, can differ so widely, it’s inevitable that there are
differences in the sound heard as well. Based on a wealth
of actually measured data, YAMAHA CINEMA DSP uses
YAMAHA original sound field technology to combine
Dolby Pro Logic, Dolby Digital and DTS systems to
provide the visual and audio experience of movie theater
in the listening room of your own home.
SILENT CINEMA
YAMAHA has developed a natural, realistic sound effect
DSP algorithm for headphones.
Parameters for headphones have been set for each sound
field so that accurate representations of all the sound field
programs can be enjoyed using headphones.
