Parametric EQ
There are five bands of parametric EQ for each channel. The
frequency can be set in 1/12 octave frequency steps. The filter
bandwidth is set and displayed in octaves. The level can be
adjusted over a +/- 15 dB range. Press the encoder to select the
desired parameter to adjust. Return the cursor to the upper
left corner when done to scroll to other screens.

Horn EQ
The Horn EQ provides a 6dB per octave high frequency boost
that is sometimes required for high frequency horns. The
frequency control sets the low frequency corner of the filter.
To return to the Main Menu, select Discard and Exit or Save and
Exit.

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
System (mS) Delay screen
1 mS steps for system alignment. These delays can be set
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 DSP amplifiers display the equivalent

delay distance in meters and feet in the system delay and
Driver alignment (uS) screen
centimeters or inches in the driver delay.
Limiter
The Pro-LITE DSP has limiters available on each channel.
®
These limit the signal level to the input of the power amplifier
stage. The limit threshold starts at zero and is adjusted in -1 dB
steps, reducing the maximum output. You must be aware that
the Pro-LITE DSP works the same as most other amplifiers
®
in that their maximum output depends on the line voltage and
load impedance. Depending on load, you may need to reduce
Limiter screen
the limiter up to 3 dB before the output is reduced.
