CINEMA DSP (Digital Sound Field Processor)
Since the Dolby Surround and DTS systems were originally designed for use in movie theaters, their effect is
best experienced in a theater that has many speakers designed for acoustic effects. Since home conditions
(such as room size, wall material, and number of speakers) can differ so widely, it is inevitable that there are
differences in the sound that you hear. Based on a wealth of actually measured data, CINEMA DSP,
Yamaha’s original DSP technology provides the audiovisual experience of a movie theater in your own
home.
CINEMA DSP 3D
The actually measured sound field data contain the information of the height of the sound images. CINEMA
DSP 3D mode achieves the reproduction of the accurate height of the sound images so that it creates the
accurate and intensive 3D sound fields in a listening room.
Compressed Music Enhancer
The Compressed Music Enhancer feature compensates for missing harmonics in compression music
formats (such as MP3). As a result, this technology provides improved performance for the overall sound
system.
SILENT CINEMA
Yamaha has developed a natural, realistic sound effect DSP algorithm for headphones. Parameters for
headphones have been set for each sound program, so that accurate representations of all the sound
programs can be enjoyed on headphones.
Virtual CINEMA DSP
Virtual CINEMA DSP allows the system to virtually reproduce the sound field of the surround speakers with
front left and right speakers. Even if the surround speakers are not connected, the unit creates the realistic
sound field in a listening room.
Virtual Presence Speaker (VPS)
Virtual Presence Speaker allows the system to virtually reproduce the height of the 3D sound field without
front presence speakers. Even if the front presence speakers are not connected, the unit creates the 3D
sound field in your room.
YPAO (Yamaha Parametric room Acoustic Optimizer)
The Yamaha Parametric room Acoustic Optimizer (YPAO) function detects speaker connections, measures
the distances from them to your listening position(s), and then automatically optimizes the speaker settings,
such as volume balance and acoustic parameters, to suit your room.
