Fig. 6.8: Triple stereo delay line
In this application, the ULTRADRIVE PRO is not used as a crossover network. Instead, it produces stereo delay lines, i.e. stereo speaker cabinets delayed in time with
regard to each other. All pairs of cabinets are supplied with the same full-range stereo input signal A+B. Then, these pairs can be placed at regular distances away
from the stage, as is often the case at big open-air concerts. The farther away the original signal (usually the music played on stage) is, the more audible the delay
between speaker signal (close to the listener) and original signal (far away) becomes. The DCX2496 allows you to make up for the resulting echoes by adding specific
delay times to the speaker signals. This allows the audience to feel as if they were "part of it" even though they may be far away from the stage—and this without any
annoying echoes.
