VERIS 2 OPERATION MANUAL
INTRODUCTION
In 2007 Community introduced the VERIS line of loudspeakers. It rapidly became one of our most
successful product families.
Now, in 2012, we have re-engineered the VERIS family and re-named it VERIS 2. These all-new
loudspeakers retain the size, shape and features that have become highly sought after, following the
introduction of the original VERIS line - while simultaneously providing significantly improved
performance. Technology marches on… and we’ve used the best and latest materials, manufacturing
techniques and acoustical methodology to improve VERIS 2, without adversely harming the
performance-to-price ratio.
Some of the new exciting VERIS 2 technologies include:
A powerful one-inch High Frequency driver that outperforms anything in its class. The new HF
driver also permits lower frequency crossover points, thereby providing better integration with the
cone drivers as they approach the crossover region.
All crossovers have been re-designed and individually voiced to increase uniformity among the
various models in the line.
Models that employ dual cone-drivers, the V2-26 and V2-28, now utilize improved frequency-
shading of one of the cone drivers. This improves the polar response, as well as the frequency
response, throughout the crossover region.
The smaller VERIS 2 models, the V2-6, V2-8, V2-26, and V2-28 feature a new rotatable horn
design that allows optimal dispersion in either vertical or horizontal mounting positions. Accessed
by removing the front grille, the horn may be easily rotated in the field.
All models in the line feature re-engineered protective front grilles. The new grilles have larger
perforated openings that reduce reflective interference without sacrificing structural integrity.
The VERIS 2 product family includes a new dual 15” subwoofer called the V2-215S. Additionally, all
full-range models benefit from the introduction of new optional Vertical Yoke Brackets.
OVERVIEW
The ability of VERIS 2 loudspeakers to meet the needs of a broad range of installation requirements,
at affordable price points, is truly unmatched. Venues such as nightclubs, cafes, discotheques, houses
of worship, auditoriums, lecture halls, restaurants, theatres, and almost anywhere else that people
gather to enjoy music or hear the spoken word, are within the ability of the VERIS 2 line to respond
with acoustical perfection.
VERIS 2 excels in applications that require controlled coverage patterns, high-impact power response,
and intelligible sonic output. VERIS 2 loudspeakers are flexible, easy to install, and most importantly,
they provide excellent sound quality.
This manual is intended to help you install VERIS 2 loudspeakers effectively and safely. It provides
useful information to assist in obtaining the best sound quality, overall performance, and reliability
from VERIS 2 products.
We’ve provided several easy-to-understand diagrams that enable you to quickly grasp the main
features of VERIS 2 loudspeakers; however, we recommend that you take the time to read the entire
manual to insure that your VERIS 2 installations meet the highest possible standards of performance
and safety standards.

VERIS 2 – Operation Manual - Page 7
VERIS 2 TECHNOLOGIES
VERIS 2 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 patented
technology reduces distortion, improves transient response, and provides as much as 30%
greater cone area than that of conventional cone drivers of the same rated size.
Ferrofluid-cooled high-frequency and mid-frequency drivers for improved heat transfer and
dramatically reduced distortion by means of viscous damping of the driver’s resonant
modes.
Powerful one-inch-throat high-frequency compression drivers offer extended high-end
response, smooth output, and lower distortion than previous 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 VERIS 2 subwoofers).
DYNA-TECHTM 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.
Load-rated threaded rigging fittings on tops, bottoms, and rear of enclosures for safe &
easy rigging.
NL4-compatible locking connector, plus a screw-type terminal strip wired 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 are available in either black or white finish, at no additional cost.
NEW! Protective steel grilles covered with durable powder-coat finish that also feature
increased open space to reduce harmful acoustical reflections.
NEW! Rotatable horns on V2-6, V2-8, V2-26, V2-28.
NEW! Individually voiced crossovers for each model and horn pattern.

UNPACKING AND INSPECTION
VERIS 2 loudspeakers are inherently rugged and are carefully packed in sturdy cartons. However, it is
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 is 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 damage 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 is 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)
VERIS 2 models V2-6, V2-8, V2-26, and V2-28 include a
yoke-style mounting bracket at no additional charge.
DANGER: VERIS 2 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, reduced output, and premature driver
failure.

VERIS 2 loudspeakers may be used in multiples, forming clusters and arrays. Systems may
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 2 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.

VERIS 2 – Operation Manual - Page 14
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 2 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

VERIS 2 – Operation Manual - Page 15
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.
Figure 3: Community’s Cool-Coil™ Heat Evacuation System
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
V2-6 Full-Range 100 Hz, 24db/octave

CONNECTING THE AMPLIFIER TO THE LOUDSPEAKER
All VERIS 2 Series loudspeakers are provided with two methods of connecting the amplifier to
the loudspeaker. One is an industry standard NL4 type locking connector, and the other is a
pressure-screw terminal strip. These two connectors are wired in parallel with each other, on
all models.
Figure 4: VERIS 2 Input Panel
The following figure is an example of a typical input panel used on VERIS 2
loudspeakers. A similar panel is used on all standard, low impedance VERIS 2 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 NL4 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 2 Input Panel, Optional Autoformer Version
The following figure is an example of the input panel used on VERIS 2 loudspeakers
equipped with an optional autoformer. Such models are intended to be used in a 70V
or 100V “constant voltage distribution system.”

VERIS 2 – Operation Manual - Page 17
Typical Input Panel for Autoformer Equipped Models
PIN DESIGNATIONS
The pin designation is as follows:
‘C’ (meaning ‘Common’) connects to the ‘C’ or Ground connection on the
amplifier (typically a black binding post, or the 1- pin of an NL4 type connector).
The selected tap connects to the positive output of the amplifier (typically a red
binding post, or 1+ on an NL4 type connector).
USING POWER TAPS
A VERIS 2 loudspeaker equipped with an optional autoformer has four 70.7V taps and three
100V taps. The 70.7 volt taps 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. The 100V taps are set
at 50W, 100W and 200W on the two larger models, and 25W, 50W, and 100W on the two
smaller models.
By choosing one of the 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. 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, the installer 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 sound 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, the effect of room acoustics can (and usually
will) 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 the installer to 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.

VERIS 2 – Operation Manual - Page 18
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-up the voltage becomes extremely important. In Europe
and Asia most constant voltage systems use the 100V standard; in the USA the 70.7 voltage
standard is most often utilized.
A VERIS 2 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 amplifier 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 if the loudspeakers share the same acoustic space. The result
will be less power output than if only one loudspeaker were used by itself.
TIP: When using the barrier strip for wiring, we recommend that you first terminate
the wire with a plated copper crimp-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 NL4 TYPE CONNECTORS
The following diagram shows how connections are made to an NL4 type of 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
Note: Pins 2+ and 2- are not used in VERIS 2 loudspeakers.
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.

VERIS 2 – Operation Manual - Page 19
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 avoids passing any
transient ‘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.
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.

VERIS 2 – Operation Manual - Page 20
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 8Ωload or 576 watts into a 4Ωload:
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.
