Linear PCM is a signal format under which an analog 
audio signal is digitized, recorded and transmitted without 
using any compression. This is used as a method of 
recording CDs and DVD audio. The PCM system uses a 
technique for sampling the size of the analog signal per 
very small unit of time. Standing for “pulse code 
modulation”, the analog signal is encoded as pulses and 
then modulated for recording.

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. 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 a movie theater in the listening room 
of your own home.

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 on headphones.

YAMAHA has developed a Virtual CINEMA DSP 
algorithm that allows you to enjoy DSP sound field 
surround effects without any surround speakers by using 
virtual surround speakers.
It is even possible to enjoy Virtual CINEMA DSP using a 
minimal two-speaker system that does not include a center 
speaker.
