VERIS SERIES
OPERATION MANUAL
INTRODUCTION
Thank you for selecting Community’s VERIS Series. VERIS is a stunning collection of
affordable loudspeakers designed for permanent installation in venues such as nightclubs,
cafes, discotheques, houses of worship, auditoriums, lecture halls, restaurants, theatres,
and most anywhere else that people gather to enjoy music and hear the spoken word.
VERIS excels in applications requiring controlled coverage patterns, high-impact power
response, and intelligible sonic output.
VERIS loudspeakers are flexible, easy to install and use, and most importantly they provide
excellent sound quality.
This Operation Manual is intended to help you install VERIS loudspeakers effectively and
safely. It provides useful information to assist in obtaining the best performance, sound
quality, and reliability from your VERIS products.
We’ve provided several easy-to-understand diagrams to enable you to quickly grasp the
main features of VERIS loudspeakers; however, we recommend that you take the time to
read the entire manual to insure that your VERIS-powered installations meet the highest
possible quality and safety standards.
VERIS TECHNOLOGY
VERIS loudspeakers offer numerous advances in technology that provide superb sound and
long-term reliability. Some of these include:
• Sophisticated internal crossover networks for reduced off-axis lobing and consistent
coverage throughout the crossover region.
• Carbon Ring Cone Technology. Used on all full-range low-frequency drivers, this
technology reduces distortion, improves transient response, and provides as much
as 30% greater cone area than that of conventional cone drivers (patent pending).
• Ferrofluid-cooled high-frequency and mid-frequency drivers for improved heat
transfer and dramatically reduced distortion, through viscous damping of driver
resonant modes.
• Powerful 1-inch-throat high-frequency compression drivers offer extended high-end
response, smooth output, and lower distortion than larger format drivers.
• Non-metallic high-frequency diaphragms provide a further reduction in distortion
by eliminating the mechanical resonance normally associated with brittle metallic
materials.
• Community’s patented Cool-Coil
driver power compression and ensures long-term reliability (used in subwoofers).
• DYNA-TECH
under abusive conditions.
• Rugged 11-ply, 18mm cross-laminated Birch enclosures, coated with a two-part
catalyzed polyester paint for durability.
• Protective steel grilles covered with durable powder-coat finish.

• Load-rated threaded rigging fittings on tops, bottoms, and rear of enclosures for
safe & easy rigging.
• NL4-compatible locking connector with terminal strip in parallel for easy
connectivity.
• Factory designed rigging hardware and mounting brackets available from stock.
• Smaller models may be ordered with an optional low distortion, low insertion-loss
autoformer for 70V and 100V applications.
• All models available in black or white finish at no additional cost.
UNPACKING AND INSPECTION
VERIS loudspeakers are inherently rugged and are carefully packed in sturdy cartons.
However, it’s wise to thoroughly inspect each unit after it has been removed from the
packaging, as damage could occur during shipping.
Please note that once the shipment has left your dealer or the Community factory, the
responsibility for damage is always borne by the freight company. If damage has occurred
during shipping, you must file a claim directly with the freight company. It’s very important
to contact the freight company as soon as possible after receiving your shipment, as most
freight companies have a short time limit within which they will investigate claims. Make
sure to save the carton and the packing material, as most claims will be denied if these
materials are not retained. Your Community dealer and the factory will try to help in any
way they can, but it is the responsibility of the party receiving the shipment to file the
damage claim.
It’s always a good idea to retain the carton and packing materials indefinitely, if possible, in
the event that the unit may need to be returned to your dealer or distributor for repair in
the future.
Each shipping carton contains the following items:
• Loudspeaker System (Qty 1)
• Operation Manual (Qty 1)
• Warranty Card (Qty 1)
DANGER: VERIS rigging fittings are rated at a Working Load Limit (WLL) of 100 lbs
(45.4kg) with a 10:1 safety margin. No single rigging fitting should ever be subjected to a
load that is greater than this stated limit. Failure to heed this warning could result in injury
or death!
IMPORTANT: The flat-head Allen-drive rigging screws that come installed in each
enclosure must either be replaced with rigging brackets and threaded fasteners, or they
must be kept in place to seal the enclosure from air leaks. If the rigging fittings do not
remain sealed, air leaks will occur in the enclosure that will compromise the low-frequency
performance with distortion and reduced output.

be designed around horizontal splayed arrays, vertical splayed arrays, as well as exploded
clusters and distributed configurations. Rigging kits are available from the factory as
standard items.
DYNA-TECHTM DRIVER PROTECTION SYSTEM
All VERIS Series loudspeakers employ Community’s advanced technology DYNA-TECH
driver protection system. Functioning as a multi-stage limiter, DYNA-TECH circuitry
provides precise and repeatable protection by reducing excessive power to the drivers
under abusive conditions.
The first stage of limiting is designed to protect against short-term excess power applied to
the high-frequency driver(s) in the system. This circuit utilizes an HPCCR (High Positive
Current Coefficient Resistor) in series with the driver(s). The HPCCR increases resistance
as the current flowing through it increases. As its resistance rises above nominal, the
heating of the element provides RMS conversion. The result is an RMS limiter with a ratio
that varies according to the demands of the program material.
The second stage of limiting protects against excessive power levels to all drivers in the
system. This stage is based on an electro-mechanical relay driven through a voltage
sensing circuit. The relay engages at a pre-determined voltage, corresponding to a power
level that would otherwise cause driver damage. When engaged, the relay introduces a
bank of high-wattage resistors in series with the drivers. These resistors cause a voltage
drop to the drivers, thereby reducing the power applied to them. A red LED on the rear
panel indicates that this protection circuit has been engaged.
When the relay protection circuit is activated, there will be a noticeable drop in the system’s
level (approximately 3 to 4 dB). The red LED, as well as the drop in level, serves as a
warning to the operator that the loudspeaker is being overdriven. When this stage of
protection is engaged, the level of the console and/or the amplifier’s output to the
system should be reduced.
Community VERIS Series - Operation and Installation Manual - Page 13
IMPORTANT: If the operator continues to run the system at excessive levels, or worse, if
the operator raises the drive level to compensate for the drop in output caused by the
protection circuitry, eventually an additional stage of protection will engage that shuts down
the system entirely (note that this additional stage of protection will never engage until
after the second stage has been triggered). If the system shuts down entirely, the operator
can immediately restore sound by simply reducing the drive level to the system.
Advantages of Community’s DYNA-TECH Circuitry
There are numerous advantages to this type of multi-stage protection circuitry. The trip
point is pre-set to engage at exactly the same time on all speakers that are powered from
the same amplifier. The initial stages of DYNA-TECH protection circuitry do not rely on, and
are not affected by heat build-up. Some manufacturers use circuit breakers that require
heat build-up before they trip; this limits their ability to protect a cold speaker. The trip
points of such breakers are also affected by ambient temperature, their own internal
heating curves, and small variations in speaker impedance or crossover component
tolerances, all of which can cause unpredictable behavior.
Because the first and second stages of Community’s DYNA-TECH circuits are not thermally
sensitive, they react nearly instantaneously to protect against an excessive increase in
level. Moreover, the protection disengages almost immediately when the drive level to the
system is reduced; it is not necessary to wait for a circuit breaker to cool down. This
means that your loudspeaker can operate at its full dynamic range and still react quickly to
protect against excessive musical peaks, avoiding damage to the system. It also means
that your loudspeaker is protected from the moment the power amplifier is plugged in and
turned on, regardless of the ambient temperature.
As mentioned above, the protection circuitry provides a third level of protection for the
entire loudspeaker to guard it from severe misuse. If the system is operated in the secondstage mode of protection for a long period of time, or if the input level is increased to try to
overcome the volume drop from the second-stage protection circuitry, a solid-state circuit
breaker will trip and remove all signal from the loudspeaker until the input level is reduced.
Because this circuit breaker is heat sensitive, it provides a final level of protection that
takes heat into account as well as power. However, unlike most implementations of circuit
breakers that take time to cool down before resetting, DYNA-TECH circuits respond
instantly to a reduction in level, restoring the system to its full dynamic range without
needing to wait for the circuit breaker to reset itself.
COOL-COIL™ TECHNOLOGY
The cone drivers used in the VERIS subwoofers utilize Community’s patented Cool-Coil™
heat evacuation technology. A proprietary process, Cool-Coil employs an airflow director to
remove heat from the voice coil, thereby increasing both the performance and reliability of
the cone drivers. In particular, the effect of Power Compression is significantly improved by
Cool-Coil technology. Power Compression occurs when drivers respond non-linearly to
applied power, producing less and less output as their voice coils heat up and their
impedance rises.
High voice coil temperatures have other undesirable effects on performance. Most materials
used in drivers, particularly adhesives and insulation, suffer some diminished properties
under extremes of heat. Thermal expansion can result in warpage and misalignment of
components. A voice coil in which the diameter has increased due to thermal expansion
will often no longer be round, and certainly has a greater possibility of rubbing against the
magnetic structure.
Any amount of cooling that can be applied to a woofer will be beneficial. One very
commonly used cooling method is venting of the pole piece of the magnet structure.
The motion of the cone assembly will pump air in and out of the cavity under the dust cap.
This air passing through the pole vent helps to cool the magnet structure. Community has
improved on this common cooling method by introducing an airflow director (US patent
6,390,231) into the air path. Figure 3 shows a conventional woofer motor with a vented
pole piece, and also a similar motor with the addition of an airflow director. The voice coil
former in the airflow motor is aluminum, and is taller than normal. This extended
aluminum former becomes a cooling fin for the voice coil, and the airflow director causes
the air to pass in close proximity to the former. By directing the air to flow over the hot
aluminum former, more heat is removed from the voice coil than simply allowing the
Community VERIS Series - Operation and Installation Manual - Page 14
pumped air to take its natural path in and out of the cavity. This results in woofers that can
handle higher power with greater reliability than those of conventional design.

HIGH-PASS FILTERS
We strongly encourage the use of an external, active high-pass filter to protect the cone
drivers from excessive low-frequency excursion. A high-pass filter will eliminate the
potential of low-frequency modulation from wind noise, turntable rumble, stage vibration,
and other causes that result in a poorly defined and ‘muddy’ bass response. Additionally, a
high-pass filter will avoid wasting amplifier power by keeping the amplifier from attempting
to reproduce frequencies below the loudspeaker’s intended operating range. The table
below shows the recommended filter settings:
Model High-Pass Filter
VERIS6 Full-Range: 100 Hz, 24db/octave
VERIS8 Full-Range: 90 Hz, 24db/octave

CONNECTING THE AMPLIFIER TO THE LOUDSPEAKER
All VERIS Series loudspeakers come with two methods of connecting the amplifier to the
loudspeaker. One is an industry standard NL4 type locking connector, and the other is a
terminal strip. These two connectors are wired in parallel with each other, on all models.
Figure 4: VERIS Input Panel
The following figure is an example of a typical input panel used on VERIS loudspeakers.
A similar panel is used on all standard, low impedance VERIS models. The loudspeaker is
intended to be connected directly to the amplifier.
Typical Standard Input Panel
PIN DESIGNATIONS
For all models the pin designation is as follows:
• NL4 Pin 1+ or the terminal screw labeled (+) connect to the positive (red)
output of the amplifier.
• NL4 Pin 1- or the terminal screw labeled (-) connect to the negative (black)
output of the amplifier.
Note that the NL-4 and the terminal strip are wired in parallel, and that Pins 2+ and 2- on
the NL4 connector are not utilized.
CAUTION: Be sure to carefully observe polarity when wiring your loudspeakers. If one
loudspeaker is wired with the opposite polarity from another loudspeaker, acoustic
cancellation will occur. The result will be less acoustic power output than if only one
loudspeaker were used by itself.
Figure 5: VERIS Input Panel, Optional Autoformer Version
The following figure is an example of the input panel used on VERIS loudspeakers equipped
with an optional autoformer. Such models are intended to be used in a 70V or 100V
“constant voltage distribution system.”
Community VERIS Series - Operation and Installation Manual - Page 16
Typical Input Panel for Autoformer Equipped Models
PIN DESIGNATIONS
The pin designation is as follows:
• ‘C’ or ‘common’ connects to the ‘C’ or Ground connection on the amplifier
(typically a black binding post).
• One of the taps connects to the positive output of the amplifier (typically a red
binding post).
USING POWER TAPS
A VERIS loudspeaker equipped with an optional autoformer has four taps. These are set at
25W, 50W, 100W and 200W on the two larger models, and 12.5W, 25W, 50W and 100W on
the two smaller models.
By choosing one of the four taps, you can govern how much amplifier power is available for
each loudspeaker. For example, if the 50W tap is selected, that particular loudspeaker will
draw 50 watts of power when a 70V amplifier is run at its maximum level. A second
loudspeaker might be connected to the same amplifier, but tapped at 100W (100 watts). In
such case, the second loudspeaker will draw 100 watts from the same amplifier, making it 3
dB louder than the first loudspeaker. A third loudspeaker might be tapped at 200 watts,
which would make it 3 dB louder than the second loudspeaker, and 6 dB louder than the
first.
By using the various taps, one can balance the relative sound levels in a system. A
loudspeaker that is closer to audience members will need to be tapped at a lower wattage
than one that is farther away, in order to produce similar levels.
Typically, every time you double the distance from a sound source, the level drops by 6 dB,
which is equivalent to one-fourth of the power. Although this is an acoustical law, and is
true in a free space environment such as outdoors, be aware that the effect of room
acoustics can radically change the actual results. Even outdoors, it is normally not possible
to validate this acoustical law using a sound level meter, due to the ground plane effect.
That said, the use of pink or white noise to excite the system, and a sound level meter to
take nearfield measurements, will help you precisely balance the relative level of each
loudspeaker in a sound system. Just make sure to take your readings at an identical
distance from each of the loudspeakers in the system, otherwise the results will be skewed.
Community VERIS Series - Operation and Installation Manual - Page 17
70.7V and 100V SYSTEMS
Several voltage standards have been put in place regarding so called ‘constant voltage
systems.’ In the United States, 25V, 70.7V and 100V are common. Occasionally 140V
systems can be found, usually in very large venues such as racetracks, where the need to
overcome cable resistance by scaling the voltage up is extremely important. In Europe and
Asia, most constant voltage systems use the 100V standard.
A VERIS loudspeaker equipped with the optional autoformer will support both the 70.7V and
100V standards. The same screw terminals are used for both voltage standards, but the
power level of the tap is different, depending on whether the voltage is 70.7V or 100V.
Note that on the rear input panel, the power levels above the horizontal line refer to a
70.7V system, while the power levels below the line refer to a 100V system.
A 100V system will produce twice the power at a given tap, as that of a system run at 70.7
volts. This can be verified by the simple Ohm’s Law calculation E
2
/Z = W, where E is the
voltage applied, Z is the load impedance, and W is the power expressed in Watts.
Assuming a load impedance of 50 ohms, we can see that 70.7 x 70.7 / 50 = 99.97 and that
100 x 100 / 50 = 200. Therefore, when scaling up from 70.7V to 100V the power will
double; when scaling down, the power will halve.
CAUTION: Be sure to carefully observe polarity when wiring your loudspeakers. If one
loudspeaker is wired with the opposite polarity from another loudspeaker, acoustic
cancellation will occur. The result will be less power output than if only one loudspeaker
were used by itself.
C-TIP: When using the barrier strip for wiring, we recommend that you first terminate the
wire with a plated copper crimp-on type spade lug, using moderate to heavy pressure on
the crimp tool. When the spade lug is tightened firmly on the barrier strip, it will form a
gas-tight connection resistant to corrosion. Be careful not to over-tighten the barrier strip
screws, as they can sheer off under too much torque. This is the recommended method of
wiring for fixed installations, especially those that may be exposed to inclement
environmental conditions.
WIRING NEUTRIK TYPE CONNECTORS
The following diagram shows how connections are made to a Neutrik SpeakonTM style
loudspeaker connector. Terminations may be soldered, or made by means of their built-in
screw and pressure clamp. If using the pressure clamp, it’s important to tighten it fully,
then to wait about ten minutes (longer is better), then to tighten it again. This is because
copper wire flows under pressure. After initially tightening the screw clamp, some minutes
later the screw will no longer be as tight due to the effect of the compression on the
copper. Typically, only one cycle of “tighten – wait – re-tighten” is required for a secure
connection.
Figure 6: NL4-Type Connector
NEUTRIK SPEAKON™
CONNECTOR – NL4FC
Note: Pins 2+ and 2- are not used in the VERIS loudspeaker series.
DANGER: When wiring the amplifier(s) to the loudspeaker(s), always power-down the
amplifier(s) and disconnect their AC Mains plug(s). Many modern, high power amplifiers
can deliver enough voltage and current to cause a harmful or lethal electric shock. Shocks
from very low frequencies, such as kick drums, can cause the human heart to stop beating
at relatively low power levels.
Community VERIS Series - Operation and Installation Manual - Page 18
WARNING: After wiring the amplifier(s) to the loudspeaker(s), first power up all devices
that are upstream of the amplifier, such as mixers, equalizers, compressor/limiters, etc.,
before powering-up the amplifier. This is to avoid passing any clicks or pops that may
originate in the upstream devices to the loudspeakers. The amplifier should initially be
powered-up with its gain controls turned all the way down. After making sure that a
continuous signal is present, such as a CD playing, slowly raise the level of the gain
controls to establish that the wiring has been installed correctly. Only then should the
loudspeaker be operated at normal output levels.
KNOW YOUR AMPLIFIER
Not all amplifiers can safely drive low-impedance loads, though usually 4 ohms and higher
is not a problem. Very low impedance loads may cause the amplifier to clip prematurely,
overheat, shutdown, or fail altogether due to internal device damage.
Even when an amplifier is quite stable driving a low impedance load, cable loss will be
greater than with moderate impedance loads, damping factor will be reduced, and if the
amplifier were to fail, a larger portion of the sound system is likely to be taken off-line due
to the fact that a low impedance load implies a larger number of loudspeakers being
powered from a common amplifier.
C-TIP: Keeping the loads at 4 ohms or higher will lengthen the life of your amplifier(s) and
improve the reliability and overall sound quality of the system.
CHOOSING LOUDSPEAKER WIRE
Wire and cable is used to transfer power between the amplifier and the loudspeaker. Wire
and cable can be purchased with copper and aluminum conductors; for loudspeakers only
copper conductors should be utilized.
The construction, conductor type, and insulation material of wire and cable vary widely.
Wire can be purchased with solid core construction, stranded core construction, and densely
stranded construction. Cables are typically available only as stranded or densely stranded.
Speakers may be driven through individual conductors bundled together and pulled through
conduit, or through a cable made up of a number of conductors covered with an overall
jacket, which then may or may not necessarily be installed in a conduit. Wire and cable
manufacturers offer multi-conductor cables with 30 or more high current conductors
covered with a variety of jacket types. Jackets may be made of PVC, rubber, neoprene,
and other materials, depending on the intended conditions of use.
Generally speaking, the wires and cables that power loudspeakers do not need to be
twisted into pairs, though there is some benefit to doing so. A twisted pair of conductors
has the effect of cancelling electro-magnetic radiation, thereby reducing mutual induction
among circuits that share the same physical space (such as a cable tray or conduit), along
with canceling the crosstalk that might otherwise result.
Twisted pairs are commonly used for balanced line signal and microphone cables, in which
the nominal voltages are very low and the input impedance of the load is typically quite
high (>10K ohms). Under such conditions, the use of a twisted pair is essential to reduce
crosstalk among adjacent cables. The twisting insures that the differential amplifier in a
balanced line receiver will see identical phase and amplitude of any extraneous Electro
Magnetic Interference (EMI) induced in the cable on both polarities, thereby allowing the
EMI to be differentially cancelled.
In contrast, however, loudspeakers have input impedances that are quite low and operate
on much higher voltages. The potential of inducing an audible signal from adjacent wiring
is close to zero. The installer may, however, choose to use twisted pair loudspeaker cable
for other reasons. Certain amplifiers may exhibit instability when driving long lengths of
wire installed in conduit. A twisted pair will insure that the reactance of the loudspeaker
cable is identical on both the plus and minus wires, thereby presenting a more stable load
to the amplifier.
Note that when specifying multiple twisted pairs of speaker cables intended to share the
same conduit, the conduit will need to be sized much larger than with loose or bundled
conductors.
Community VERIS Series - Operation and Installation Manual - Page 19
CONDUCTORS AND INSULATION
Solid conductor wire is slightly less expensive than stranded wire, but much more difficult
to pull through conduit. Also, it does not terminate to most speaker connectors as easily as
stranded wire. Therefore, we recommend using stranded THHN type wire for installations
that involve conduit.
Densely stranded cables, typically used for portable cordage, will coil up easily and lay flat
on the stage, making them a good choice for applications requiring portability such as floor
monitors. Typical examples are 14/2 and 14/4 SJO. Such cable is normally stocked in
many hardware stores.
Wire and cable insulation is always rated for a working voltage and a maximum
temperature. In power distribution systems, wire and cables can get very hot, making the
temperature rating extremely important. When used with loudspeakers, the temperature of
the wire or cable will hardly ever rise more than 10º C above ambient, and voltages will
never exceed 300V (which is the minimum rating of most industrial wire and cable).
Special cables are manufactured for installation in air plenums, while others are made for
direct burial. Use of such products can save a lot of time and expense compared to
installing conduit. However, local, state, or federal building codes may require that
loudspeaker cables are installed in conduits or in cable trays. Therefore, it’s a good idea to
check applicable regulations carefully, before beginning any installation.
In the United States, conductors are sized according to a numbering system know as the
American Wire Gauge, or AWG. Larger numbers, such as #22 or #24 indicate smaller
diameter wire, while smaller numbers such as #10 and #12 indicate larger diameter wire.
In other parts of the world, the metric system is widely used to define conductor diameter.
Metric equivalents can be converted to US AWG sizes, with only a small loss of precision.
The larger the diameter of the conductor, the lower the resistance will be for a given length.
Resistance is normally stated per foot, or per hundred feet of wire. For example, #10
stranded copper THHN has a resistance of .204 ohms per hundred feet, though this can
vary slightly among manufacturers.
The resistance of the wire, the impedance of the load, and the output voltage of the
amplifier will determine how much loss occurs in the wire. These parameters also govern
the damping factor of the amplifier/speaker combination (more on this later).
Below is a table that gives a quick look at the effect of wire size on line loss. These
numbers assume that the amplifier is producing a constant 48 Volts at its output terminals,
which is equivalent to 288 watts into an 8Ω load or 576 watts into a 4Ω load:
Size Length Load Z Loss in dB
#10 AWG 100’ 8Ω -0.42 dB
#10 AWG 200’ 8Ω -0.83 dB
#10 AWG 100’ 4Ω -0.83 dB
#10 AWG 200’ 4Ω -1.58 dB
#12 AWG 100’ 8Ω -0.66 dB
#12 AWG 200’ 8Ω -1.28 dB
#12 AWG 100’ 4Ω -1.28 dB
#12 AWG 200’ 4Ω -2.39 dB
#14 AWG 100’ 8Ω -1.03 dB
#14 AWG 200’ 8Ω -1.95 dB
#14 AWG 100’ 4Ω -1.95 dB
#14 AWG 200’ 4Ω -3.55 dB
The worst-case scenario shown above is the 200’ run of #14 AWG into a 4 ohm load. This
will result in a staggering loss of -3.55 dB, or more than half of the amplifier’s total power
output. Use of wire that’s one size smaller, #16 AWG, would cause a power loss of -5.11
dB. This approaches a 75% loss of total available power! As you can readily see, it’s very
important to use the largest gauge wire that you possibly can, particularly when long lines
are unavoidable. Note: NL4-compatible connectors easily accept #12 AWG.
