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.

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!
Jumpers shown in “Low Z (4 ohm)” position 2
The input routing jumpers are configured from the factory in the position shown
above (Low Z). They must be moved by the user if “High Z” (70.7Vrms or
100Vrms) operation is required.
NOTE:
For high-impedance connections the internal jumpers must be moved from
position 2 to position 1.
Jumpers shown in “High Z” position 1
CONNECTING THE CFA-2
The input barrier strip wiring is shown below. NOTE the “No Connection” (NC)
positions for each wiring configuration. Please note that when wiring for
100Vrms or 70.7Vrms operation there are various connections that are not used
(NC) based on whether the desired operating voltage is 70.7Vrms or 100Vrms.
SUSPENDING THE CFA-2
The CFA-2 may be suspended using either the stainless steel “U” bracket
(supplied) or by using either the Pole Mount System EX-3 for pole applications or
the PT-76 for either wall or pole mounting. The CFA-2 may be suspended
horizontally using points 1 and 3 shown below via M10 eyebolts.
The CFA-2 rigging points (M10 - 9 points) and mounting point for the “U” bracket
hardware kit (M8 - 1 point (NOT A SUSPENSION POINT) are shown below.
The points shown in red are all M10. The single blue colored point is M8. The
points are numbered in this image to illustrate intended usage as follows:
Points 1 and 2……………..”U” Bracket mount (the blue point, M8, is also used for
the “U” bracket strap kit. The blue M8 point is NOT a structural point and is used
for the “U” bracket strap ONLY!)
Points 1 and 3, 4 and 5…….Horizontal enclosure mount. NOTE: All 4 points,
(Points 1, 3, 4, and 5) must be used for horizontal mount configurations. Point 4
and 5 are for pull up and safety!
Point 6………………………Four points used for either the PT-76 or the Pole
Mount System EX-3 (NOTE: Point 4 is used for the “link” portion of the PT-76 or
the Pole Mount System EX-3 mounts)
The supplied “U” bracket requires the enclosure be suspended “upside down”
with the high frequency section positioned near the bottom of the front baffle. The
“U” bracket will allow adjustment in the vertical axis (tilt) only. See the image
below. NOTE: THE CENTER HOLE IN THE U BRACKET IS FOR THE PULL
BACK STRAP ONLY! THIS HOLE MUST NOT BE USED FOR MOUNTING OR
SUSPENSION!
CFA-2 orientation for external “U” bracket (supplied)
The CFA-2 is supplied with the external “U” bracket and a hardware kit to allow
the enclosure to be tilted back and locked into position. This kit prevents wind
loading and “gravity sag” from altering the required down tilt angle of the
enclosure
The kit consists of:
1ea. Band-it AE4779 All Purpose Band 316SS (Black Coated) 475mm long
2ea. M8 304 grade stainless steel bolts
1ea. M8 304 grade stainless steel nylon insert nut
3 ea. 304 flat washers
1 ea. Lock washer
The M8 fitting is located between the M10 points.
NOTE: The M8 point should NOT be used for rigging.
The M8 point is to be used to mount the hardware kit ONLY!
THE CENTER HOLE IN THE U BRACKET IS FOR CONNE CTING THE STRAP
ONLY! DO NOT USE THE CENTER M8 HOLE IN THE U BRACKET FOR
MOUNTING OR SUSPENDING THE ENCLOSURE !!!
The “U” bracket kit is shown installed above and a close up below.
The stainless steel band is connected to the “U” bracket by using one M8 bolt
and flat washer on the top as shown in the close up below. A second flat washer
and the nylon insert nut are used below the “U” bracket to secure the stainless
steel band to the top of the “U” bracket.

The band is secured on the back of the enclosure using the M8 point, a flat
washer, a lock washer and the second M8 bolt as shown above.

The above image shows the back of the CFA-2 and the strap kit mounting.
The CFA-2 is shown below with both the PT-76 and the Pole Mount System EX-
3. When the CF A-2 is suspended using either the Pole Mount System EX-3 or
the PT-76 the enclosure must be oriented with the woofers near the bottom of the
mount.

CFA-2 with Pole Mount System EX-3
NOTE: When the CFA-2 is used with either the PT-7 6 or the Pol e M ount System
EX-3 the enclosure is rotated 180 degrees as shown above and below. The high
frequency horn is located near the top for use with the PT-76 or the Pole Mount
System EX-3.

Installation instructions for both the Pole Mount EX-3 and the PT-76 may be
found in the “Documentation” section of the One Systems web site.
