The color fade function will change the colors at a slow rate, with all the lights the same color. The
effects speed control sets the change time. The fastest change will be every ½ second. The slowest
is approximately every 4 minutes. With the control in the middle the change is every 15 seconds.

The strobe function is white only and operates from one flash every 3 seconds to 6 flashes per
second controlled by the effects speed control.

The audio chase has 7 colors and advances on the start of each 90 Hz audio beat. The fade rate
is affected by the effects speed control. Setting the effect rate control in the middle is optimum for
normal operation.

This is the classic Color Organ function, but implemented with DSP technology to increase the
response to transients and to allow each channel to continuously adjust the gain. The high band is 8
kHz to 15 kHz and the mid band is 700 Hz to 3 kHz using IIR filters. The high bass is centered at 90
Hz and the low bass is centered at 45 Hz both using FIR filters that respond in about ¾ of a cycle.
The fade rate is determined by the fade rate control. This effect can be made significantly faster with
the fade rate control. The low bass is blue, high bass red, mid green and high yellow-orange.
NOTE: FIR and IIR stand for Finite Impulse Response and Infinite Impulse Response. These are
com-mon terms for digital audio filters.

This is similar to the function above but with the audio midrange band excluded and the 90 Hz
high bass channel routed to 2 lamps per bar. This creates a display with more emphasis on flash-
ing with the music beat. The low bass is blue, high bass red and high is green. The fade rate is
faster but can be slowed down with the effects speed control.

Lights are flashed two at a time modulated by the bass beat. The pair colors are rotated in 5 steps
and 7 steps to create pseudo random color pairing. The position pairing repeats after 6 steps.

All four lights are flashed modulated by the bass beat. There are two lights of each color with the
colors rotated in 5 steps and 7 steps to create pseudo-random pairing.
