CROSS FIELD ARRAY-2 (CFA-2)

Long Throw/High Intelligibility

All-Weather Loudspeaker System

V100/2015

The One Systems Cross Field Array-2™ (CFA-2) was designed to provi de v ery
high intelligibility and acoustic output where long throw requirements are

specified. The CFA-2 is a nominal 55 degree horizontal by 30 degree array that

features a fully rotatable high frequency horn/waveguide. This allows the CFA-2

to be used in either a vertical or horizontal orientation and still allows the desired
coverage patterns. The high frequency configuration consists of two large format
close-spaced compression drivers coupled to a 2” (50.8mm) constant directivity
horn. The low frequency configuration consists of 4 bandwidth optimized 10”
(254mm) diameter woofers in a 2 x 2 array. The CFA-2 is ideal for both
outdoor/direct weather long throw applications and indoor applications in high
ambient noise environ men ts . Ty pi c al ap pl i cations are football and soc cer fiel ds,
baseball fields and larg e theme park environm ents . Indoor environments such as
basketball arenas and natatorium installations ar e w ell suited due to the ultra-

high system inte lligib ility.

In order to achieve maxi mum sys tem performance the CFA-2 should be high
pass filtered using a 4
filter frequency can be set using the O ne Sy s tems SF -4 High Pass Filter system
or by using any high quality DSP based loudspeaker processor. High pass filter
frequencies as low as 60Hz may be used but maximum system dynamics and
headroom are achieved by using the recommended 80Hz filter corner frequency.

The CFA-2 is a direct weather design that features a three layer stainless steel
grill assembly. The enclosure design is a laminated fiberglass construction with
high safety factory structural rigging points molded in the enclosure s hell . Ther e
are 9 M10 rigging points and the system is supplied with a stainless steel “U”
bracket for simple suspension. The “U” bracket also includes a stainless steel
strap kit that allows the desired tilt angle to be set and maintained regardless of
wind loading.

th

order (24dB/octave) high pass filter set to 80Hz. This

The system is also compatible with the One Systems Pole Mount System EX-3 if
vertical tilt requirements are specified in a pole mount application. The One
Systems PT-76 is also compatible with the CFA-2 when pan and tilt are required.

The CFA-2 has an internal 600 watt autoformer and an internal jumper system
that allows the enclosure to be used in either a “Lo Z” (4 ohm) or “Hi Z”
configuration. The aut o for mer t aps ar e 600 w atts , 300 watts, and 150 watts. The
input will allow for either 70.7Vrms operation or 100Vrms operation. The
autoformer is a very low insertion loss (<0.4dB) impedance converter that
exhibits very wide bandwidth.

NOTE: The CFA-2 is factory configured f or 4 ohm operation. Internal jumpers are
supplied and must be re-configured for “Hi Z” operation.

System input is a five position barrier strip. The input section features an
aluminum weather cover with an integral IP68 rated glad nut. The gland nut will
accommodate cable outside diameters of 7mm to 12mm (0.236” to 0.472”). The
maximum diameter will accept most 2 conductor AWG12 cable assemblies.

CONFIGURING THE CFA-2

NOTE: The One Systems CFA-2 has a factory installed 600 watt autoformer.

The CFA-2 may be configured to present either a “Low Impedance” (4 ohm) or
“High Impedance” load to the amplifier. The CFA-2 is wired at the factory for 4
ohm operation. If a “High Impedance” configuration is required, the crossover
input cup must be removed and the configuration jumpers must be moved as
shown below.

For Low Impedance (4 ohms) all jumpers must be in POSITION 2.
For High Impedance (either 70.7Vrms or 100Vrms) all jumpers must be in

POSITION 1.

THE INPUT WEATHER COVER MUST BE USED FOR ALL CFA-2
INSTALLATIONS, REGARDLESS OF SYSTEM INPUT IMPEDANCE!
