SYSTEM SETUPS
Speaker systems can be scaled from small to large for the size of the venue
and type of performance, using different speakers in different positions as you
grow a system. For instance a single pair of SCx1112’s or SCx1115’s on pole
stands may be all that is required for a certain situation. Adding SCx1118 or
SCx1118A subs will expand your system for bigger performances, while still
making use of your initial investment. Larger systems add the SCx1253 for main
audience coverage, with the SCx1112 or SCx1115 as stage monitors or side fill.
For the most demanding applications, two SCx1118(A)’s can be used (per side)
to keep up with the high SPL output of one SCx1253 per side.
The SCx1000 loudspeakers feature internal passive crossovers, allowing you
to build systems using full range audio from your power amps with excellent
results.
BIAMPING AND ADVANCED SYSTEM CONTROL
With the SCx1118A, use the XLR THRU jack with the HI PASS OUTPUT switch
engaged to drive the power amp for your SCx1112 or SCx1115 to reduce the
power needed to drive these cabinets.
Active electronic crossovers such as Carvin’s XD360 X-Drive can be used for
more advanced control. Bi-amping, and 2- or 3-way setups allow more efficient
use of speakers and power amps. See the chart for recommended crossover
frequencies.
STACKING AND USING SPEAKER STANDS SAFELY
Ensure that the floor, stage or soundwings are level and solid. Be cautious
of outdoor windy conditions, speaker stacks could topple over in high wind
conditions or be accidentally pushed or bumped over by over-zealous crowds.
Loudspeakers producing very high SPL (especially subwoofers) can shift from
their original position. Ensure the feet of the loudspeakers are locked into the
feet cups of the speaker below. Place frictional material between the floor and
the loudspeaker.
