Setting the audio outputs and the final effects |833
Turning the separate effects on/off
▪ Use the On/Off buttons on top of each slider to turn the corresponding ef-
fect on/off.
Programming the Master effects
▪ Use the IN/OUT indicators to check the level of the audio entering and com-
ing out of the MaxxAUDIO processor. Be sure the indicators never go to the
red area (since this means distortion).
▪ Use the virtual sliders to increase or decrease the level of the corresponding
parameter.
If the input level is too high, decrease the level of the Sounds, Styles, Songs
that are playing.
If the output level is too high, decrease the level of the various Maxx AUDIO
controls (in particular, the Volume control).
MaxxBass
MaxxBass is for low frequency response beyond what your loud- speakers
can deliver. You will hear low frequencies as much as 1.5 octaves below the
limits of your loudspeakers.
MaxxBass isolates the low bass frequencies that can’t be reproduced by the
loudspeakers. The low frequencies are analyzed to create a complex set of
higher frequency harmonics, which the loudspeakers can reproduce.
These harmonics are added back to the rest of the audio, replacing the origi-
nal low frequencies. Your loudspeakers then reproduce the harmonic series,
which are perceived by the brain as the original low frequencies. Finally,
MaxxBass uses dynamic compression to focus and clarify the lower frequen-
cies.
The result is larger, more powerful sound, with extended bass response up to
1.5 octaves below the roll-off frequency of the loudspeaker.
MaxxTreble
MaxxTreble is for enhanced high frequencies; it is ideal for one-way driver
systems.
Using technologies originally developed for Waves professional audio plug-
ins, MaxxTreble is a non-linear dynamic processor that enhances high fre-
quency response, delivering a clean and pleasant high end, while minimizing
distortion.
