9. Supports and trolleys
The equipment should be only used on trolleys or supports, where necessary, that are
recommended by the manufacturer. The equipment / support / trolley assembly must be
moved with extreme caution. Sudden stops, excessive pushing force and uneven floors may
cause the assembly to overturn.
10. There are numerous mechanical and electrical factors to be considered when installing
a professional audio system (in addition to those which are strictly acoustic, such as sound
pressure, angles of coverage, frequency response, etc.).
11. Hearing loss
Exposure to high sound levels can cause permanent hearing loss. The acoustic pressure level
that leads to hearing loss is different from person to person and depends on the duration
of exposure. To prevent potentially dangerous exposure to high levels of acoustic pressure,
anyone who is exposed to these levels should use adequate protection devices. When a
transducer capable of producing high sound levels is being used, it is therefore necessary
to wear ear plugs or protective earphones. See the manual technical specifications to know
the maximum sound pressure level.

POWER
REQUIREMENTS
AND SET-UP
The HDL line arrays Systems are designed to operate in hostile and demanding situations.
Nevertheless it is important to take extremely care of the AC power supply and set up a
proper power distribution.
The HDL line arrays Systems are designed to be GROUNDED. Always use a grounded
connection.
WARNING
The HDL amplifiers are designed to work within the following AC Voltage limits:
230 V NOMINAL VOLTAGE: minimum voltage 185 V, maximum voltage 260 V
115 V NOMINAL VOLTAGE: minimum voltage 95 V, maximum voltage 132 V.
If the voltage goes below the minimum admitted voltage the system stops working If
the voltage goes higher than the maximum admitted voltage the system can be seriously
damaged. To obtain the best performances from the system it is very important that the
voltage drop it is as low as possible.
VOLTAGE
Make sure that all the system is properly grounded. All the grounding points shall be
connected to the same ground node. This will improve reducing hums in the audio system.
GROUNDING
The module is provided with a Powercon outlet to daisy chain other modules. The maximum
number of modules that is possible to daisy chain is:
16 (SIXTEEN) OR 4 HDL 18-AS + 8 HDL 20-A MAXIMUM OR 8
HDL18-A.
AC CABLES DAISY CHAINS
230 Volt NOMINAL VOLTAGE: minimum voltage 185 Volt, maximum voltage 264
Volt (for UK 240V+10%)
115 Volt NOMINAL VOLTAGE: minimum voltage 95 Volt, maximum voltage 132
Volt.
6
A superior number of modules in daisy chain will exceed the Powercon connector maximum
ratings and create a potentially dangerous situation.
WARNING
When the HDL line arrays systems are powered from a three phase power distribution it
is very important to keep a good balance in the load of each phase of the AC power. It is
very important to include subwoofers and satellites in power distribution calculation: both
subwoofers and satellites shall be distributed between the three phases.

1 MAIN XLR INPUT (BAL/UNBAL). The system accept male XLR/Jack input connectors
with line level signals from a mixing console or other signal source.
2 LINK XLR OUTPUT. The output XLR male connector provides a loop trough for
speakers daisy chaining.
3 VOLUME. Controls the volume of the power amplifier. The control ranges from (maximum attenuation) to the MAX level ∞ (maximum output).
4 POWER INDICATOR. Power on indicator. When the power cord is connected and
the power switch is turned on this indicator lights green.
5 SIGNAL INDICATOR. The signal indicator lights green if there is signal present on
the main XLR input.
6 LIMITER INDICATOR. The amplifier has a built in limiter circuit to prevent clipping
of the amplifiers or overdriving the transducers. When the peak clipping circuit is active
the LED blinks orange. It is okay if the limit LED blinks occasionally. If the LED blinks
frequently or lights continuously, turn down the signal level. The amplifier has a built
in RMS limiter. If the RMS limiter is active the LED lights red. The RMS limiter has the
purpose to prevent damages the transducers. The speaker shall never be used with
the limit indicator red, continuous operation with the RMS protection active can cause
damages to the speaker.
7 HF. The switch gives the possibility to set high frequencies correction depending on
target distance (air absorption correction):
- NEAR (used for pole mount applications or near field)
- FAR (for farthest field).
8 CLUSTER. The combination of the 2 switches gives 4 possibilities of mid low
frequencies correction depending on cluster size.
- 2-3 modules (used for pole mount applications ground stacking)
- 4-6 modules (small flown systems)
- 7-9 modules (medium flown systems)
- 10-16 modules (maximum flown configuration).
9 HIGH CURVING. The switch gives the extra possibility to boost mid frequencies
depending on a high curving cluster configuration of few pieces.
- OFF (not active correction)
- ON (for high curving arrays of few pieces HDL20-A or HDL10-A).
10 INDOOR. The switch gives the extra possibility to set low frequencies correction
depending on a indoor/outdoor use, in order to compensate room reverberation on
lows.
- OFF (not active correction)
- ON (correction for reverberant indoor rooms).

At this point you can connect the power supply cable and the signal cable, but before
turning on the speaker make sure that the volume control is at the minimum level (even
on the mixer output). It is important that the mixer is already ON before turning on the
speaker. This will avoid damage to the speakers and noisy “bumps” due to turning on parts
on the audio chain. It is a good practice to always turn on speakers at last and turn them
off immediately after the show.
Now you can turn ON the speaker and adjust the volume control to a proper level.

Audio signal can be daisy-chained using the male XLR loop through connectors. A single
audio source can drive multiple speakers modules (like a full left or right channel made of
8-16 speaker modules); make sure that the source device is able to drive the impedance
load made of the modules input circuits in parallel. The HDL line arrays input circuit presents
a 100 KOhm input impedance. The total input impedance seen as a load from the audio
source (ex. audio mixer) will be:
- system input impedance = 100 KOhm / number of input circuits in parallel.
SIGNAL CABLES DAISY CHAINS
The required output impedance of the audio source (ex. audio mixer) will be:
- source output impedance > 10 * system input impedance;
- always make sure that XLR cables used to feed audio signal to the system are:
- balanced audio cables;
- wired in phase.
A single defective cable can affect the performance of the overall system!

SINGLE HDL20-A, HDL10-A
The HDL is a flexible system that can be used in ground-supported or suspended applications.
The following information will help you set up your HDL system safely and effectively.
When using stands or poles, be sure to observe the following precautions:
- Check the stand or pole specification to be certain the device is designed to support the
weight of the speaker. Observe all safety precautions specified by the manufacturer.
- Be certain that the surface on which the system is to be stacked is flat, stable and solid.
- Inspect the stand (or pole and associated hardware) before each use and do not use
equipment with worn, damaged, or missing parts.
- Do not attempt to place more than two HDL loudspeakers on a stand or pole.
- When mounting two HDL speakers on a pole or tripod, integral rigging hardware must be
used to secure the speakers to each other.
- Always be cautious when deploying the system outdoors. Unexpected winds may topple
a system. Avoid attaching banners or similar items to any part of a speaker system. Such
attachments could act as a sail and topple the system.
POLE AND TRIPOD SAFETY
WARNINGS
A single HDL may be used on a tripod stand (AC S260) or on a pole (AC PMA) over its D
LINE Series subwoofers. The use of a subwoofer is recommended for applications requiring
more low-frequency power and extension and needs a pole (P.N. 13360110).
Usually, the cluster switch on the input panel should be set to the 2-3 position and the HF on
NEAR when a single speaker is used. Indoor switch use depends on the speaker placement.
Place the speaker or the pole on a tripod using its own hardware LIGHT BAR HDL20-A (P.N.
13360229) or LIGHT BAR HDL10-A (P.N. 13360276) as shown in the following picture.

WARNING
The suspension system is designed to have a proper Safety Factors (configuration
dependent). Using the “RCF Shape Designer” software it is very easy to understand safety
factors and limits for each specific configuration. To better comprehend in which safety
range the mechanics are working a simple introduction is needed: HDL mechanics are
built with certified UNI EN 10025-95 S 235 JR and S 355 JR Steel. RCF prediction software
calculates forces on every single stressed part of the assembly and shows the minimum
safety factor for every link.
“RCF SHAPE DESIGNER”
SOFTWARE AND SAFETY
FACTOR
S 235 JR is a structural steel and has a stress-strain (or equivalent Force-Deformation) curve
like the following.
The curve is characterized by two critical points: the Break Point and the Yield Point. The
tensile ultimate stress is simply the maximum stress attained. Ultimate tensile stress is
commonly used as a criterion of the strength of the material for structural design, but it
should be recognized that other strength properties may often be more important. One
of these is for sure the Yield Strength. Stress-strain diagram of S 235 JR exhibit a sharp
break at a stress below the ultimate strength. At this critical stress, the material elongates
considerably with no apparent change in stress. The stress at which this occurs is referred
to as the yield point.
Permanent deformation may be detrimental, and the industry adopted 0.2% plastic strain
as an arbitrary limit that is considered acceptable by all regulatory agencies. For tension
and compression, the corresponding stress at this offset strain is defined as the yield.
S 355 J and S 235 JR characteristic values are R=360 [N/mm2] and R=510 [N/mm2] for
Ultimate Strength and Rp0.2=235 [N/mm2] and Rp0.2=355 [N/mm2] for Yield Strength. In
our prediction software the Safety Factors are calculated considering the Maximum Stress
Limit equal to the Yield Strength, according with many international standards and rules.
The resulting Safety Factor is the minimum of all the calculated safety factors, for each link
or pin.
This is where you are working with a SF=4:
Depending on local safety regulation and on situation the required safety factor can vary.
It is responsibility of the owner or rigger to make sure that the system is properly rigged
in accordance with Country and local laws and regulations. The “RCF Shape Designer”
software gives detailed information of the safety factor for each specific configuration.

ENGLISH
The safety factor is the result of the forces acting on fly bar’s and system’s front and rear
links and pins and depends on many variables:
- number of cabinets;
- fly bar angles;
- angles from cabinets to cabinets. If one of the cited variables change the safety factor
MUST BE recalculated using the software before rigging the system.
In case the fly bar is picked up from 2 motors make sure that the fly bar angle is correct. An
angle different from the angle used in the prediction software can be potentially dangerous.
Never allow persons to stay or pass under the system during the installation process.
When the fly bar is particularly tilted or the array is very curved the centre of gravity can
move out from the rear links. In this case the front links are in compression and the rear
links are supporting the total weight of the system plus the front compression. Always
check very carefully with the “RCF Shape Designer” software all this kind of situations
(even with a small number of cabinets).

ARRAY SYSTEMS
DESIGN
HDL allow users to choose from different face-to-face angle adjustments to create arrays
with varying curvature. Thus, designers can create arrays custom-tailored to each venue’s
profile.
The basic approach to array design dependent on three factors:
- Number of Array Elements;
- Vertical Splay Angles;
- Horizontal Coverage.
Determining the number of elements to use is critical: the number of elements greatly
affects the SPL available from the system as well as the uniformity of coverage in both SPL
and frequency response. The number of elements profoundly effects the directivity at lower
frequencies.
The next easy equation, works as an approximation for flat listening planes.
Coverage (x) ≈ 8n (m) Coverage distance required = x (metres).
Changing the splay angles between cabinets has a significant impact on vertical coverage
for the high frequencies, with the result that narrower vertical splay angles produce a
higher Q vertical beamwidth, while wider splay lowers the Q at high frequencies. In general,
the splay angles do not affect the vertical coverage at lower frequencies.
The curved array system design can be summarized as:
- flat-front HDL for long throw sections;
- increase curvature as distance decreases;
- add more enclosures for more output.
This approach focuses more transducers mounted on long-throw horns at the farthest seat,
gradually focusing fewer transducers as distance decreases. As long as the no gap rule is
maintained, arrays constructed according to these principles will provide even SPL and a
consistent sonic character throughout the venue without requiring complex processing.
This approach, where the same amount of acoustic energy is spread over a larger or smaller
vertical angle depending on required throw, typically have the following objectives:
- even horizontal and vertical coverage;
- uniform SPL;
- uniform frequency response;
- sufficient SPL for the application.
This discussion represents, of course, just a basic approach. Given the infinite variety of
venues and performers, users will find themselves needing to solve specific problems in
specific situations. RCF Shape Designer software designed to help calculate optimum splay
angles, aiming angles, and fly-bar pick points (crucial in aiming the array) for a given venue,
will be explained later in this Guide.

ENTERING VENUE DATA
For best results, planes should be used as follows:
FLOOR is used to simulate the main floor area from the stage to a rear bleacher or
boundary.
PLANE 1 is used to simulate any audience continuation behind FLOOR (e.g. a rear bleacher)
from the end of the main floor to furthest and highest seat below PLANE 2.
PLANE 2 is used to simulate the furthest/highest audience area.
Enter the height, length and elevation of up to three planes.
For all planes Length refers to the horizontal length of that plane.
For all planes Height refers to the height of the rear of the plane.
For PLANES 1 and 2 Elevation refers to the elevation (height) of the front of the plane.
For PLANE 1 and 2 Distance relates to the actual distance from the front of the array to the
start of the plane.
For all planes selecting Seated or Standing places ear level at 1.3 or 1.7 m above the
respective plane.
Specify the horizontal coverage distances from the front of the array.
COVERAGE
Select either Suspended or Stack in the Array installation section to determines how the
array is supported.
ARRAY INSTALLATION
In Suspended mode the grid is suspended and cabinets are attached beneath.
In Stack mode the grid forms a base and cabinets are placed on top.

AUTO H SETTING - MIN TRIM HEIGHT
This is the low limit for the array and is defined as the smallest allowable distance from the
lowest point of the array to the ground below
AUTO H SETTING - MAX SUSPENSION POINT
Set this to the maximum array height allowable (usually the highest part of the flying frame).
The maximum pick height is usually chosen to allow for the maximum flying point height
minus a sensible allowance for any shackles, stingers, bridles or flying hooks. 1m should be
allowed for a stinger between each grid flying lug and the relevant motor hook to ensure that
motor chain bags do not rest on the grid or top cabinet and upset its tilt angle.

OPTIMIZING
THE ARRAY
Once the design (number of elements and vertical splay angles) has been designed using
Shape Designer software, you can effectively optimise the array depending on the environment
and the application by driving it using different DSP presets stored onboard. Typically arrays
are divided in two or three zones depending the design and size of the array.
To optimise and EQ the array, different strategies are used for high frequencies (long throws
and short throws) and low frequencies.
The longer the distance, the greater the attenuation at high frequencies. Generally, high
frequencies need a correction to compensate for energy lost over distance; the correction
needed is usually proportional to the distance and high-frequency air absorption. In the
near- to mid-field, the air absorption is not nearly as critical; in this zone, high frequencies
need little additional correction.
HIGH-FREQUENCY
EQUALIZATION STRATEGIES
In the next figure is shown the equalization that corresponds to HF settings for NEAR and
FAR:

ENGLISH
While wave-guides provide isolated control over various mid- to high-frequency coverage areas,
the low-frequency section of a HDL array still requires mutual coupling - with equal amplitude
and phase - to achieve better directionality. Low-frequency directionality is less dependent on the
array’s relative splay angles and more dependent on the number of elements of the array.
LOW-FREQUENCY COUPLING
EFFECTS
At low frequencies, the more elements in the array (the longer the array), the more directional the
array becomes, providing more SPL in this range. The directional control of the array is achieved
when the length of the array is similar or larger than the wavelength of the frequencies being
reproduced by the array.
Although the array can (and usually should) be zoned for implementing different
equalization curves for high frequencies, identical equalization should be maintained in all
the low-frequency filters.
Different low-frequency equalization settings in the same array will degrade the desired
coupling effect. For the same reason, gain differences are not recommended for line arrays,
since adjusting various zones with an overall amplitude control for each results in decrease
of Low-frequency headroom and directionality.
In any case, line arrays generally need a correction to compensate for energy sum on lows.
LOW-FREQUENCY STRATEGIES
In the next figure is shown the equalization that corresponds to CLUSTER settings, referring
to different number of speakers from 2-3 up to 10-16. Increasing the number of cabinets,
response curves are decreased in order to compensate the low-frequency section mutual
coupling.

2) The stacking bar adds a fixed amount of up or downtilt to ground-stacked HDL
loudspeakers, with additional 15 degrees of adjustment possible (from +7,5° to -7,5°).
3) Connect front bracket of the first HDL cabinet using 2 quick lock pins.

4) The baffle of the bottom box in a stacked array does not necessarily have to be parallel
to the stage or the array frame. It can be tilted up or downward if desired. In this way arced
arrays can be readily created from a ground stack position.

5) The bottom box in a stacked array can be tilted to obtain proper coverage patterns (from
+7,5° to -7,5°). Reverse and connect the 1 rear stacking bar bracket to the first enclosure
using the hole for the proper angle and quick lock pins.
Add HDL cabinets one by one as indicated for flown configurations. Up to four HDL
enclosures can be stacked and interlinked using the standard D LINE rigging components
and the D LINE subs as ground support.
6) It is possible to stack HDL speakers on the ground using its own fly bar as shown in the
pictures.
