SYSTEM CONFIGURATIONS
FIGURE 2 and FIGURE 3 show the possible configurations for the XLT and XLTE loudspeakers and subwoofers.
FIGURE 2 shows the possible configurations when your full-range system is operated in PASSIVE mode both with and
without an XLT or XLTE subwoofer. FIGURE 3 shows the possible configurations when your full-range system is
operated in BIAMP mode both with and without an XLT or XLTE subwoofer.
NOTE: The figures show only basic system components needed for connecting the loudspeakers.
Refer to SECTION 6.4 for exact details about wiring the connectors. You will also find this information listed on the
input panel label of the loudspeaker.
5.2.1
Configuring a Full-Range System with a 51 or 55 Subwoofer
In each figure there are two methods shown for configuring a subwoofer with a full-range loudspeaker. These are
shown in FIGURES 2C & 2D and in FIGURES 3B & 3C. The difference is whether a separate amplifier channel is used
to power the subwoofer. While both methods are acceptable to use, the following points should be considered.
1.
Using one amplifier channel for both the full-range loudspeaker and subwoofer (as shown in FIGURE 2C
and FIGURE 3B) means you need fewer amplifier channels for the overall system. However, the acoustical
balance between the full-range loudspeaker and the subwoofer will be determined by the inherent efficiencies of
the full-range loudspeaker and the subwoofer. Refer to SECTION 5.1.2 for load impedance considerations when
using this feature.
2.
Using separate amplifier channels for the full-range loudspeaker and subwoofer (as shown in FIGURE 2D
and FIGURE 3C) means more amplifier channels are required for the overall system. However, the acoustical
balance between the full-range loudspeaker and the subwoofer can be adjusted to suit your personal taste by
using the input level controls on your amplifiers.
3.
Using an electronic crossover will allow more precise division of the audio frequencies, when using
separate amplifier channels for the full-range loudspeaker and subwoofer. Community cannot provide
