Examples For Active 2-Way Applications - Dynacord System Power Amp Xa 4000 Owner's Manual

EXAMPLES FOR ACTIVE 2-WAY APPLICATIONS

Fig. 1 shows a standard setup consisting of 2x Xa 4000, 2x FX12 used as Mid/Hi cabinets and 4x FX 20 used
as woofer cabinets. This all-purpose setup fulfills the requirements of most applications. The use of four FX
20 bass cabinets produces solid low-frequency sound reproduction, which is most favorable for revival and
jazz-rock bands as well as for other bass drum-oriented musical styles when performed in medium size clubs
or festival tents.
Sound reinforcement of side areas can be realized through employing additional „sidefill" speaker systems,
like for example compact 2- or 3-way fullrange cabinets, which are simply connected via the TOP-Speakon
socket of the Xa 4000. This connector carries the Mid/Hi audio signal via pins 1+/1-.
Fig. 2 shows a variation of the standard setup that is advantageous for wider stages. Whenever placing the
loudspeaker cabinets on stage is possible, in most cases the use of a single FX 20 woofer to elevate the FX
12 Mid/Hi cabinet in the correct height on top of the woofer is sufficient. The remaining two woofer cabinets
are configured as center cluster in the middle and in front of or under the stage providing homogeneous
coverage of the audience area. In addition to that extra degree of homogeneous coverage this left-center-
right setup allows achieving higher SPL in the low-frequency range.
