13 ACTIVE MULTI-WAY SPEAKERS
When used in the bi-amp and tri-amp speaker configuration modes, the DEQX becomes
the heart of an active speaker, with each driver being driven by a dedicated amplifier
channel. The bi-amp and tri-amp speaker configuration modes are supported by the
HDP-4, HDP-5, and HDP-Express II.
The bi-amp and tri-amp configurations are considered an advanced mode of operation,
as using them will require knowledge of the intricacies of speaker design as well as
improved measurement technique. The explanation assumes that Chapters 5 to 9,
which focus on the single-amp speaker configuration modes, are already fully
understood.
Bi-amp and tri-amp modes can potentially damage drivers if settings are incorrect. The
symbol at left will appear wherever particular note must be paid to settings or options.
13.1 ACTIVE CONFIGURATIONS WITH DEQX
By way of introduction to active speakers, Figure 4 illustrates a system using a pair of
passive two-way speakers and a DEQX running in single-amp speaker configuration
mode. The internals of the right speaker are shown for illustrative purposes.
