The Dolby Surround Pro-Logic decoder integrated in the HEARO 999 AUDIOSPHERE derives
a center and a surround channel from a Pro-Logic encoded stereo signal. The IVA processor
converts these signals to a binaural format equivalent to that reproduced by four high quali-
ty loudspeakers (3 front, 1 rear speaker). This lets you enjoy the 360° listening experience of
Dolby Surround even through headphones.
Also integrated in the HEARO 999 AUDIOSPHERE, the Dolby Digital decoder processes digi-
tal multichannel signals in Dolby Digital format for perfect reproduction via headphones.
Dolby Digital provides even better channel separation and five loudspeaker channels. The IVA
processor converts these signals to a binaural format equivalent to that reproduced by five
high quality loudspeakers (3 front, 2 rear speakers).
The VMAx processor enables a single pair of loudspeakers to provide surround sound.
Similar to IVA, VMAx processing derives three-dimensional sound from analog or digital input
signals. VMAx will simulate the appropriate loudspeakers for Dolby Pro-Logic and Dolby
Digital encoded input signals.
VMAx also allows you to increase the virtual distance between closely spaced stereo loud-
speakers (e.g., speakers placed next to a computer monitor).
The processed signal is available at the analog audio output so you can use a standard stereo
amplifier to reproduce the VMAx signal.
B: Listening through headphones:
Amplitude and phase differences
are eliminated. Sound sources
are localized inside the head rat-
her than in the room.
C: Listening through headphones
with IVA processing: The ear
matching function modifies the
audio signals at the ears to
resemble diagram A. This resto-
res natural, spatial hearing.
