508| Audio In/Out and the Voice Processor
Using MaxxTreble technology you will be able to deliver louder, crisper and
better defined high end without having to worry about clipping or peak-lim-
iting.
MaxxStereo
MaxxStereo is for more realistic, wider stereo imaging. You will hear a wide,
exciting stereo image, similar to what you'd hear in a modern movie theatre.
MaxxStereo spatial imaging technology improves the stereo separation of
closely placed loudspeakers. With loudspeakers that are very close the one
to the other (like in the optional PaAS Amplification System), MaxxStereo
increases perceived separation for optimal imaging, with natural sound and
a generous listening position.
MaxxVolume
MaxxVolume is for dynamics compensation. It increases (or decreases) RMS
levels, delivering louder sound with no audible distortion.
It relies on Peak Limiting, that increases volume without clipping or audible
distortion; Low Level Compression, that increases the clarity of soft sounds,
especially in noisy environments and at quiet volumes; and Noise Gating,
that eliminates background signal and system noise.
