Figure 5 shows Variplex
TM
-XL frequency re-
sponse with presets of the Electro-Voice
Dx38 digital electronic crossover system pro-
cessor (see Crossover Equalization section).
The measurement was made with a swept
sine-wave signal, 4 volts at 500 Hz, in an
anechoic (echoless) environment. The micro-
phone was at a distance of 3.048m (10 ft),
on an axis with the aiming pointof the Mid/
Hi-frequency unit. Figure 5 shows the fre-
quency response of the individual sections
of the Variplex
TM
-XL, measured under the
same conditions but at 1 watt at 2 meters. The
results of which were then normalized to 1
watt/1 meter at 500Hz.
