The 9251 is an Aural Exciter module
which installs in one space of the Aphex Model 9000 rack or compatible dbx 900
series rack.
The Aural Exciter is an audio processor
that provides many benefits to the user, including greatly improved presence and
intelligibility without altering any other part of the audio system.
"SPR" (Spectral Phase
Refractor) restores bass clarity and punch without any increase in amplitude by
adjusting the phase relationshippf the fundamentals to the harmonics.
The "Drive" control of
previous Aural Exciters has been eliminated. Adjustable Harmonics mixing generates
a consistent amount of harmonics over a wide dynamic range.
WHY IT'S NEEDED
The audio reproduction process is
far from perfect, even under the best of circumstances. Every step causes some
degradation of the audio signal. What is happening involves the loss of some of
the harmonics or overtones of the sound, the fragile parts that give it intelligibility.
Equalizers cannot restore clarity and realism because they can only work on what's
left of the original sound, often increasing noise and distortion in the attempt.
Although the initial impression of
the Aural Exciter is often that it is some form of EQ, a comparison soon proves
the difference. Equalizers are a static, fixed process, and they cannot boost
what is no longer there. Equalizers can also add considerable power to the amplifier
output, possibly causing amplifier clipping, speaker damage, ear fatigue and/or
increased reverberation.
The Aural Exciter is a dynamic process
that actually recreates the missing harmonic material and adds it back in the
form of a very small cue signal. Because the enhancement signal is so small, it
adds little power to the audio signal. It is easily reproduced, even by low quality
systems, and is not affected by acoustic problems, such as "dead zones"
or reverberant fields. Because the harmonics or overtones created are derived
from the main signal and are musically and dynamically related, the result is
very natural and pleasing to the ear, and sounds "correct"..
Aural Exciter is a proprietary process,
patented worldwide and cannot be duplicated by any other means than a genuine
Aural Exciter.
