IMPORTANT SAFE INSTRUCTIONS
Before using our product, be sure to carefully read the manual and safe Instructions. Keep this document with the device all
time.
1 Read these instructions.
2 Keep these instructions.
3 Heed all warnings.
4 Follow all SAFETY INSTRUCTIONS as well
DANGER and OBLIGATION warnings.
5 Only use attachments / accessories
specified by the manufacturer.
6 Use only with the cart, tripod, bracket or
table specified by the manufacturer, or sold
with the apparatus. When a cart is used, use
caution when moving the cart / apparatus
combination to avoid injury from tip-over.
7 If the equipment is used in a manner not
specified by the Exel Acoustic, the protection
by the equipment may be impaired.
8 Read all the Product Information document
before exploiting the system.
9 Read the Rigging Manual before installing
the system. Use the rigging accessories
described in the rigging manual an follow the
associated procedures.
CAUTION: Rigging should only be done by experience
professionals.
10 This speaker enclosure is capable of
creating a strong magnetic field. Please use
caution around the enclosure with data
storage devices such as phones, computers
or hard drivers.
11 Handles are for moving the system only.
12 Beware of sound levels. Never stand in the
immediate vicinity of loudspeaker driven at
high level. Professional loudspeaker
systems are capable of causing a sound
pressure level (SPL) detrimental to human
health. Hearing damage can also occur with
prolonged exposure to sound: 8h at 90
dB(A), 30 min at 110 dB(A), less than 4 min
at 130 dB(A) Source: European Directive
relating to the assessment and management
of noise 2002/49/CE
13 When setting up the loudspeaker or
loudspeaker stand, make sure they are
standing on a firm surface. If you place
several enclosure on top of one another, use
straps to secure them against movement.

1.2 Overview the CLa21
The Tecnare CLa21 line source is a compact high-power curvilinear array loudspeaker,
member of the ARRAY family of loudspeakers. Its extended high-frequency headroom delivers
clarity, precision, and a unique proximity effect over its wide operating frequency range of 60 Hz
to 18 kHz. This headroom combines with a 75-degree constant directivity dispersion patter in
the horizontal plane.
The compact size and low weight of a
CLa21 line source complies with rigging
and visual limitations. Any on-site
deployment can be easily and quickly
achieved thanks to improvements over the
previous generation rigging system. Is
equally suited to touring, rental, and fixed
installation applications. High power-to-
size ratio, low profile, and ease of use
makes it an outstanding system in
corporate AV applications, and ideal for smaller venues such as theatres, ballrooms, and clubs.
In spite of its small size, CLa21 produces a peak output of 142 dB SPL with exceptionally
frequency response, making it capable of filling much larger spaces than one might expect.
A wide range of system configurations are available for the sound designer and system
engineer, allowing high level of creative freedom. With a fixed horizontal directivity of 75° and a
vertical inter-element variation from 0˚ to 13°, the CLa21 line source is fully configurable to
match any audience geometry.
For low-frequency enhancement, CLa21 pairs with Tecnare SW-18VR, which can be
flown as part of CLa21 arrays without transition hardware. The SW-18VR shares with CLa21
the advantages of excellent power-to-size ratio, improved efficiency, and versatility.
Tecnare recommends operating the CLa21 loudspeaker on a DSP controller. Tecnare
only recommends using presets developed by Tecnare Sound System. The DP-Series
Processor and T-Series Advanced System Amplifiers are ideal for this purpose.
Thanks to dedicated factory presets, it constitutes an extremely advanced and precise
drive system for the enclosures. In high-end installation projects, the T-Series amplified
controller can deliver maximum power headroom and the best possible performances. With one
transducer section per output channel and the independent DSP treatment of each loudspeaker
enclosure, this approach brings maximum discretization with a one-to-one-to-one link, from
input-to-processing-to-enclosure.
The DP-4896 Digital Loudspeaker Controllers and the T-Series amplified controllers feature
the unique Virtual Xover limiter for passive 2-way enclosures, a Tmax transducer thermal
limiters and Xmax over-excursion protection limiter.

1.3 Connections
CLa21 loudspeaker utilizes Neutrik®SpeakON®connectors. There are two NLT4
connectors on the rear of each CLa241. These connectors mate with Neutrik®NL-4 or NL-4
compatible in-line cable connectors. All four pins of both connectors are wired in parallel to link
multiple loudspeakers on a single amplifier output. Remember that parallel connection reduces
the total impedance (Ω) seen by the amplifier.
The total impedance of loudspeaker connected in parallel must not drop below the
minimum operating impedance of the amplifier.
The following subsections describe the electrical
connections.
IN speakON®point 1+ 1- 2+ 2-
Connection LF + LF - HF + HF -
The CLa21 uses the pin assignment 1+/1+ for Low
frequency and 2+/2- for High frequency. Under special order,
the customer can required a passive version with internal
crossover network.
Using one as the input, the second connector allows for
direct connection to a second cabinet.

1.4 Processing and Amplification
Only operate Tecnare loudspeaker with a correctly configured Tecnare preset. Tecnare
offer a complete solution that guarantees the highest level of performance. A complete range of
controllers, amplified and amplified controller with DSP are available to get this objective.
Otherwise, there is a risk of damaging the loudspeaker components.
1.4.1 Processing
There are two options using our digital controllers. Our DP2696 or DP4896. The options
vary depending on the final application. Refer to DP2696 or DP4896 user manual.
1.4.2 Amplification
To power Array Series, Tecnare recommends amplifiers with the power ratings enough
to feed the loudspeakers. For high power or live applications, it is recommended to
oversize the amplifiers relative to the nominal AES output of the subwoofers.
In certain specific cases it is possible to slightly under-power the subs or loudspeakers
as long as the amplifier will not be driven to its limits.
In any case, the Tecnare processors should be deployed in front of the amp to ensure
that the amplifiers to not go into clip.
The DP4896 processors also include:
- Virtual Xover Limiter for passive systems
- Thermal protection from power surges or overload
- Xmax Excursion displacement protection
The T20-44 amplifier is the ideal companion for maximum performance of the Sub
Series loudspeakers. This amplifier controller with DSP offer a complete both preset and
protection solution for any application.

3Loudspeaker Connection
Tecnare®Sound Systems recommended operating the CLa21 loudspeaker together
Tecnare loudspeaker controllers.
Tecnare®only recommends using preset/amplifier developed by Tecnare, otherwise there is
a risk of damaging the loudspeaker components. DP Series Loudspeaker Controller, PA Series
amplifier and T-Series amplifier are ideal for this purpose.
Ensure that the right preset was selected before connecting the loudspeaker with the
amplifier.
Operating with an incorrect preset can damage part of the loudspeaker.
Ensure that the amplifier is properly size according to requirements. Under-power or
oversize power amplifier without the supervision of an expert may damage the loudspeaker.
Please note the technical specification section.
