MaxxBass
®
The MaxxBass enhancement system interacts with the
®
high-pass filter for each channel to produce bass energy in a
frequency range the loudspeaker can handle. The higher the
MaxxBass number, the more the bass is enhanced.

Delay
Delay can be used to align drivers within a loudspeaker or to
delay auxiliary speakers like those installed under a balcony.
A short delay can also be used to delay the main speakers to
align them with the drums or bass guitar. A total of 125 mS
of delay is available on each channel. 5 mS of delay is available
in 41.67 uS steps for driver alignment. 120 mS is available in
1 mS steps for system alignment. These delays can be set
System (mS) Delay screen
independently so that the driver alignment offset can be
maintained when the system alignment delay is adjusted.
The first screen in the delay Sub Menu allows the user to
decide whether the delays will be set independently or B=A.
This selection only applies to the 1 mS step system delay,
leaving the driver alignment delays to be set independently.
The Pro-LITE amplifiers display the equivalent delay distance
in meters and feet in the system delay and centimeters or
inches in the driver delay.
