HEARO SURROUND SYSTEMS
LOGIC7-Decoder
Until now, this latest development by the innovative engi-
neers at LEXICON was only used in high-end processors for
high-quality home theater systems. Now, the unique
advantages of LOGIC7 decoding are available for head-
phones for the first time.
The LOGIC7 decoder automatically identifies the input sig-
nal as mono, stereo, or surround encoded and processes
the signals appropriately.
The LOGIC7 decoder uses the localization cues contained in
stereo signals to generate a 3-D sound that conveys to the
listener a sense of envelopment in the sound rather than
standing in front of a pair of loudspeakers. Surround
encoded signals are reproduced exactly as defined in the
mix.
Dolby Surround Pro-Logic
Unlike Dolby Digital where all channels are recorded and
read separately, the Dolby Surround Pro-Logic format en-
codes and decodes surround signals in a “piggyback” ma-
trixed fashion on the two stereo tracks. Therefore, many
types of media such as VHS video or radio, and many DVDs,
too, include Dolby Pro-Logic Surround signals.
DOLBY DIGITAL inside
The digital multi-channel format of Dolby Laboratories, Inc.
used in advanced movie theater equipment is the most
widespread digital surround standard for DVDs, laser discs,
and digital TV. The distinguishing feature of Dolby Digital is
that all tracks (five audio tracks plus one subwoofer track)
are stored separately in digital form. Each loudspeaker is
fed specific audio information for optimum spatial imag-
ing.
Digital transmission
The new digital RF transmission system ensures virtually
noise-free surround sound and CD-level dynamic range. It
also eliminates blanking and interference from adjacent
frequency bands emitted, for instance, by a PC or TV set.
