In addition, when using third-party digital signal processors
to filter source signals, it is highly recommended that the fil-
ter be configured to emulate the low-cut filter used by Meyer
Sound's LD-1A and LD-2.

*If the digital signal processor does not have variable Q for
high-pass filters, the filter should be set to "Butterworth"
(Q ≅ .7).
If loudspeakers will be driven directly from a digital signal
processor, make sure the signal is sufficient to drive the total
load impedance of the connected loudspeakers (see "Loop
Connector" on page 13).
TIP:
To address the collective concerns of array
design, subwoofer integration, digital signal
processors, delay systems, and acoustical condi-
tions, a measurement system like Meyer Sound's
SIM 3 is strongly recommended.
