The ST-X DSP Series Control Program
Te control program (GUI) for t e ST-X DSP amplifiers is t e same functionally for bot t e 4-C ST-4X DSP and t e
6-C ST-6X DSP except for t e number of c annels. Bot will ave a default system in t e c annel designation column
but since you ave complete control over all functions, you can use all c annels as t ey best suit your individual
system. Download t e GUI (Grap ic User Interface) from www.zapco.com > downloads, if you ave not already done
t at, and load t e GUI from t e .exe file. Connecting t e PC: Connect t e PC to t e ST-X DSP amp using t e supplied
USB cable. NOTE: T e ST-X DSP GUI is very forgiving about PC Screen resolution. However t e ideal resolution 1600 x
900 optimal on most PC’s.
At t e very top of t e Screen you will find t e Navigation bar. C annel Setup is w ere you will tell t e program w at inputs

1. At t e left of t e main GUI Screen is t e Delay section. Since you can not sit directly in t e center of t e car, t e
program can delay t e arrival time of near speakers so it will sound as t oug you are rig t in t e middle of t e car.

t em by pair. Eac c annel as a Hig Pass (HP) and a Low Pass (LP) filter. You can c oose t e S ape of t e crossover

ot er speakers. You will also find a master level control ere and a system MUTE button.
4. T e lower section of t e GUI is devoted to equalization. Here are 15 bands of parametric equalization for eac
output c annel and you can vary Frequency, Gain, and Q (t e s ape of t e adjustment) for eac band in several ways.
Frequency: Eac band is numbered. You can simply click onto a band button and drag it to w ere you want it. W en
you click onto a band t ere is a “Heads-up display” of t e frequency, gain, and Q of t e band. Any band t at as been

To aid t e tuning process you can temporarily bypass a c annels equalization. You can also t e reset function to reset
one c annel or to reset all c annel to default positions wit no equalization.
