7
JBL VLA-C SERIES | USER’S GUIDE
2.5 - INSPECTION AND MAINTENANCE
Suspension systems are comprised of mechanical devices and, as such, they require regular
inspection and routine maintenance to ensure proper functionality. Before suspending any
speaker system, always inspect all components (enclosure, suspension frames or brackets,
eyebolts, etc.) for cracks, deformations, corrosion or missing/loose/damaged parts that
could reduce strength and safety of the array. Do not suspend the speaker until the proper
corrective action has been taken.
Installed systems should be inspected at least annually. The inspection shall include a visual survey
of all corners and load-bearing surfaces for signs of cracking, water damage, delamination or any
other condition that may decrease the strength of the loudspeaker enclosure.
Accessory suspension hardware provided with or for VLA-C systems must be inspected for
fatigue at least annually or as required by local ordinance. The inspection shall include a visual
survey of the material for signs of corrosion, bending or any other condition that may decrease
the strength of the fastener. Additionally, any eyebolts shall be checked for possible spin-out of
the enclosure.
For all other hardware and fittings, refer to the hardware manufacturer’s inspection and
maintenance guidelines for process .
JBL is not responsible for the application of its products for any purpose or the misuse of this
information for any purpose. Fur thermore, JBL is not responsible for the abuse of its products
caused by avoiding compliance with inspection and maintenance procedures or any other abuse.
Prior to suspending the system, an expert, trained and experienced in suspending speaker
systems, should inspect all parts and components.

JBL VLA-C SERIES | USER’S GUIDE
3 - MECHANICAL INFORMATION
VLA Compact suspension system and accessories are also in compliance with the ANSI E1.8
- 2012 Section 5.3.4 standard for a minimum safety factor of 5:1. Minimum safety factor
requirements are often set by local regulations and the VLA-C Calculator should be used to
verify the safety factor for each array configuration.
TIPS:
•While the VLA-C265 and VLA-C2100 have similar dimensions and weights, they
are not identical. Therefore, there may be small gaps between boxes in an array.
•Because of their similar sizes, VLA-C2100 & VLA-C265 are sometimes used
interchangeably throughout this document.

VLA-C CALCULATOR
The free VLA-C Calculator is simulation software for designing and predicting JBL VLA-C
Series systems.
Acoustical Mapping
The Acoustical Mapping tab allows for 2D sectional-view modeling of VLA-C arrays on up to
four seating planes. Included are both patterns of the VLA-C full-range boxes (VLA-C265 and
VLA-C2100) and the subwoofer (VLA-C125S). Mixed arrays may be modeled.

12
JBL VLA-C SERIES | USER’S GUIDE
Array Configuration
The Array Configuration tab describes the array and provides information about weight factors
and center of gravity (CG), along with mechanical validation of the array. The array weight
design factor is selectable between 5:1, 7:1, and 10:1. Frame options are selectable. If the array
configuration falls outside the load limits of either the speaker cabinets, the speaker interconnect
system, or the suspension system, this will be indicated via an error indication. Array statistics like
total weight, attach point span, and array height and depth are also calculated.
There are two types of warning messages, which show in red lettering at the top of the Suspension
Detail and Mapping graphics: One is “Invalid CG Location” which is when the center of gravity (CG)
is outside of the two suspension points. This indicates that the array aiming angle is not physically
achievable. A second warning is “Array exceeds load limit conditions” (may also include additional
information about which load limit factor is exceeded). This indicates that one or more of the
components of the array exceeds the selected Design Factor

Refer to the free VLA-C Calculator software for the array size cabinet suspension limits for your
particular configuration.
7 - BRACKET PLATES (ie, Angle Brackets)
Each loudspeaker model ships with a corresponding pair of bracket plates which can be seen here:
V L A - C12 5S VLA-C265 V L A- C 210 0
Orientation: Note that the FRONT arrow must always point toward the front of the loudspeaker
cabinets. This places one dot-outlined section on the top, which connects via two bolt points to
the top loudspeaker cabinet, and it places the other dot-outlined section on the bottom, which
connects via two bolt points to the lower loudspeaker cabinet.
Attach the Appropriate Plate -- See charts below for which plate and which holes to use, based on
the cabinet models and the desired inter-cabinet splay angle.
Bolt Installation – Select the bolt holes in the bracket plate that correspond to the two cabinet models
that are being connected by that plate and the desired inter-box angle setting. Use the supplied
stainless steel M10 x 35 mm bolts and lock washers to secure the angle plates to the cabinet. Remove
the neoprene washer from the locations used to attach rigging components. Insert two of the M10
bolts (with lock washers) through the holes in the top section of the bracket and thread them into the
two bottom threaded insert points in the top cabinet. Insert two of the M10 bolts (with lock washers)
through the corresponding holes in the bottom section of the bracket plate and thread them into the
two top threaded insert points in the bottom cabinet. (See diagrams)
INSTRUCTIONS: Bolt Torque Settings -- Use non-permanent thread locker such as
Loctite brand Blue 242 on the threads of all fasteners. Torque bolts to 29.5 ft•lbf (±3
ft•lbf); 40 N•m (±4 N•m)
NOTE: The composite enclosure will make noises as bolts are tightened – this is normal.
Once all the plates and bolts have been checked, install the side covers using the supplied 8x32
Philips screws. Torque screws to 2.0 ft·lbf (±0.2 ft·lbf); 2.6 N·m (±0.3 N·m).

* Because of the high transient signal capability of these HF drivers, using an even larger amp than listed may
allow through some additional output on momentary transients.
NOTE: DCI-N model amplifiers contain networking capability. DCI-DA models include
Dante input for applications that require Dante or AES67 networked audio.
DRIVING CABINETS INDIVIDUALLY
The user may wish to drive the cabinets individually if they need the ability to gain shade the
array to the resolution as indicated by the EASE (or other modeling system) model or the VLA-
Compact Line Array Calculator. Driving cabinets individually may also be useful in order to utilize
the smaller amplifier sizes, if desired.

PASSIVE VERSUS ACTIVE SETTING ON LOUDSPEAKERS
Note that the VLA-C models ship in passive mode. For diagrams showing how to wire the
speaker systems in either full-range passive mode or bi-amp mode, see the WIRING section of
this guide.
USING AMPLIFIERS WITH EXTERNAL DANTE
If a different size amplifier is needed such that a Dante model is not offered, a BSS BLU-DA or any
of the BSS Dante BLU units can be added into the system.

9 - DSP PRESETS
FIR filters and limiters for the VLA-C products have been developed specifically for the Crown DCI-N
and DCI-DA amplifiers. The list of available presets are shown below and can be found on the VLA-C
home page at www.jblpro.com.
To load a preset:
1. Download the ‘VLA-C’ Speaker tuning file.
2. Move the downloaded file to: C:\ProgramData\Harman Professional\Audio Architect (this is the
default location that Audio Architect looks at for speaker tuning files)
3. In Audio Architect, Double click the Amplifier Panel.
4. On the Device panel, click File>Open>Speaker Tuning...
5. Click yes when prompted with the following message.
6. The preset will populate the limiter, crossover, and EQ settings.
Important: Note that since it is an FIR filter you will not see filters above 300Hz as they don’t
manifest themselves the same way an IIR filter would in that setting. However, they will be
engaged. In addition, you will have plenty of filters and delays to make suitable on-site adjustments.
