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-CoilTM heat evacuation technology minimizes cone
driver power compression and ensures long-term reliability (used in subwoofers).
•DYNA-TECHTM active protection circuitry reduces the likelihood of driver damage
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.

Community VERIS Series - Operation and Installation Manual - Page 8
•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.

clusters and distributed configurations. Rigging kits are available from the factory as
standard items.
DYNA-TECH 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.

Community VERIS Series - Operation and Installation Manual - Page 14
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.
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 second-
stage 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.

Community VERIS Series - Operation and Installation Manual - Page 15
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
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

CHOOSING SIGNAL PROCESSORS
A wide variety of equalizers and loudspeaker control systems are available from numerous
manufacturers. Most of today’s products use DSP (Digital Signal Processing) to divide the
frequency band between subwoofers and full-range systems, and to provide equalization,
protective limiting, and signal delay. The use of a good quality DSP processor or
‘loudspeaker management tool’ as many such devices are often referred to, is strongly
encouraged. When properly utilized, a DSP processor provides numerous benefits that
contribute to better quality sound and longer system life. Please contact Community for
up-to-date recommendations regarding specific types and models of available products.
USING PROTECTIVE LIMITERS
Although VERIS loudspeaker systems are well protected against potentially abusive
operating conditions by their internal DYNA-TECH protection circuits, the use of an active,
outboard limiter can add an extra measure of insurance for long-term reliability.
Additionally, an active outboard limiter can be adjusted to provide a subtler degree of driver
protection, precisely tailored to each user’s specific needs in terms of musical styles and
operating conditions.
A limiter is a device that detects the level of the signal that it’s receiving over a given
interval or “time constant.” When the input level crosses a certain threshold, for longer
than a certain time period, the limiter introduces some degree of gain reduction. In turn,
the gain reduction reduces the dynamic range of the program material that reaches the
amplifier.
Limiters, and their close cousin Compressors, are used in music recording and sound
reinforcement to create certain effects such as perpetual sustain of guitar and bass notes.
They’re also widely used to reduce or eliminate peak levels from vocalists, percussionists,
and other dynamic sources, as well as often being employed to avoid overdriving amplifiers
and loudspeakers.
Limiters that are suitable for protecting loudspeaker systems are available as stand-alone
products, as well as typically being included as a function of many DSP based loudspeaker
controllers or ‘loudspeaker management systems.’
Limiters typically allow adjustment of some or all of the following parameters:
•Threshold
•Input Level
•Output Level (frequently called ‘makeup gain’)
•Attack Time
•Release Time
•Compression Ratio
Virtually all limiters allow the user to set the threshold, or level, at which point gain
reduction will occur. Most models also permit the user to adjust the limit ‘ratio.’ Ratio
refers to the magnitude of gain reduction. At a 2:1 ratio, every 2 dB increase in input level
above the threshold will result in a 1 dB increase in output. At a 10:1 ratio, every 10 dB
increase in level above the threshold will also result in a 1 dB increase in output. From
these two examples, you can readily see how the Ratio control settings will drastically affect
the dynamic range.
Incidentally, the term ‘limiting’ generally refers to ratios of 10:1 or higher (some say 20:1),
whereas ‘compression’ is the term used for lower ratios, such as 2:1 or 4:1. In fact, the
only distinction between ‘compression’ and ‘limiting’ is the ratio of gain reduction.
Many limiters will allow the user to set the time constant that determine the length of the
transients that are permitted to pass before the limiting function engages (this is called
Attack), as well as the time span in which the limiter will ‘recover,’ or return to a state of
non-limiting (called Release).
When used to protect a loudspeaker system, the limiter should be set so that gain reduction
engages at some point before damage occurs to the drivers. If the threshold is set too low,

Community VERIS Series - Operation and Installation Manual - Page 17
the resultant sound quality will be ‘squashed.’ In other words, the dynamic range of the
program material will be reduced to a degree that is audibly unpleasant. Conversely, if the
threshold is set too high, the limiter will not engage early enough to protect the
loudspeaker system from damage.
It is very difficult to suggest exact limiter settings, because the ideal setting for one system
and one style of music may be undesirable for another system or another style of music.
Coupled with this, the dynamic response characteristics of the amplifier(s) used in the
system also play a large role in determining proper limiter adjustments. Amplifiers differ
from one make and model to another in their dynamic headroom capability, sometimes
greatly, and also in how they behave when they clip (see section on Amplifier Clipping on
page 25 for more information on driver damage caused by clipping.) Because of this, we
can offer only general guidelines on how to set up your system.
Following is a brief discussion on using limiters to protect loudspeaker systems:
•The limiter should be set so that it provides some measure of gain reduction before
the amplifier(s) begin to clip. If the limiter is set so that it allows the amplifier(s)
to go into hard clipping, it will do little to protect the drivers, except perhaps in the
event of extended microphone feedback.
•If the system is large enough to handle the intended musical style in the size of
room that it’s designed to cover, i.e. if there are enough amplifiers and
loudspeakers to provide the desired SPL (Sound Pressure Level) before the
amplifiers reach clipping, then it will be possible to adjust the protective limiter so
that the amplifiers never can go into clipping, even under abusive conditions. This
will provide an excellent level of protection, without sacrificing headroom and
sound quality.
Conversely, if the system is inadequately sized for the room, or just barely
powerful enough, setting the limiter so that the amplifier(s) never goes into
clipping is probably unrealistic. Such a setting will most likely result in less sound
pressure level than desired, as well as a highly compressed sonic quality. In such
case, you can either upgrade the sound system by adding loudspeakers and
amplifiers, or you can make some intelligent compromises. By carefully adjusting
the attack time, release time, and threshold level, you can allow some of the peaks
to get through to the amplifiers while still reducing the potential for damage from
long-term abuse.
A fast attack time (under 10 ms) will limit most of the peaks in normal program
material. By lengthening the attack time, you can allow short transients to pass
through (like a snare drum), while still reducing longer peaks like vocal and
instrumental crescendos. This will improve the dynamic range, while still providing
a measure of protection.
Similarly, a long release time will tend to squash the program material, as well as
introduce an audible ramp-up in level as the limiter slowly recovers. By shortening
the release time, you can increase the short-term dynamic range. As long as the
threshold is not set too high, the limiter can still aid in protecting the drivers from
long-term overdrive, but not as thoroughly as it would in an adequately sized
system.
Be cautious of very short attack and release times, as the detector circuits may
start to track the individual cycles of a sustained low-frequency tone, creating a
‘pumping’ effect, almost like that of a tremolo circuit on a guitar amplifier.
It will take some experimentation to derive the best settings for each situation. Maximum
power and voltage ratings are stated on the VERIS Specification Table on Page 9 in this
manual; these may be used as an aid in calibrating limiter settings. Using a true RMS
voltmeter, you can measure the output of your amplifier when driven by a sine wave
generator, and adjust the limiter to prevent the amplifier’s output voltage from exceeding
the stated maximum. Make sure to do this with the loudspeaker disconnected!
Be aware, however, that static voltage settings made by taking measurements derived from
exciting the system with a sine wave generator, or other constant voltage source, will
represent only a part of the picture. The other part is the time constant. If the attack and

Community VERIS Series - Operation and Installation Manual - Page 18
release times are too long, the limiter will not protect against short-term transients; in fact,
it may never engage at all.
In summary, a protective limiter can go a long way towards preserving the lifespan of a
loudspeaker system, but only if the system is sized properly to begin with and the limiter is
carefully adjusted to properly complement the system. Obviously, it’s safer to err on the
conservative side, as the opposite approach may result in driver damage or complete
system failure.
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..

Community VERIS Series - Operation and Installation Manual - Page 19
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.”
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.

Community VERIS Series - Operation and Installation Manual - Page 20
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.
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 E2/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.
