SAFETY WARNINGS
IMPORTANT
• Protect loudspeaker lines from damage; make sure they are positioned in a way that they cannot be stepped on or crushed by objects.
• Make sure all connections have been made correctly and the loudspeaker input voltage (in a constant voltage system) or its impedance is suitable
for the amplifier output.
• Also check the suitability of the support surface to which the product is anchored (wall, ceiling, structure, etc.), and the components used for
attachment (screws, screw anchors, etc.).
• To prevent inductive effects from causing hum, noise and a bad system working, loudspeaker lines should not be laid together with other electric
cables (mains), microphone or line level signal cables connected to amplifier inputs.
• Loudspeaker lines (amplifier outputs) can have a sufficiently high voltage (i.e. 100 V) to involve a risk of electrocution: never install or connect this
loudspeaker when the line is alive.
• Make sure that no objects or liquids can get into this product, as this may cause a short circuit.
• Use only the optional devices / accessories specified by the manufacturer.

Suited to both indoor and outdoor use, the VERTUS CLA range comprises two models: CLA 803T with eight 3" full range woofers and CLA 403T with
four 3" full range woofers. Both versions have the same sleek, lightweight and durable , powder-coated aluminum housing. Completely dustproof and
waterproof, the enclosure's grille is covered with a special hydrophobic fabric to ensure absolute rejection of all atmospheric agents. Full EN54-24
certification also means both columns can be used for emergency and evacuation applications. Both the CLA803T and CLA403T are characterized
by an integrated passive directivity control system which delivers a consistent frequency-based vertical dispersion, and which offers users the choice
of two angles - NARROW and WIDE. The new functionality guarantees enormous flexibility for the integrator, even allowing for the horizontal
mounting of columns. In addition VERTUS CLA enclosure is fully modular, so multiple enclosures can be linked. Other features include a 100V line
transformer with switchable power levels. A wide range of accessories is also available for total system configuration flexibility.

SETTINGS
• For 100V constant voltage lines, position the selector on the desired power value (25W, 50W for the CLA403T model) (50W, 100W for the CLA803T
\model).
Connections with the audio line are made using the ceramic clamp included in the protective casing (E).
• The two screw clamps "+" and "-" allow the connection of both the input cable and output cable for the parallel connection of other speakers. (see fig.
3)
CAUTION: DO NOT position the selector on constant impedance when the speaker is connected in constant voltage mode (100V).
• For the low impedance connection, position the selector on 16 Ohm for the CLA403T model and on 8 Ohm for the CLA803T model.
The NARROW/WIDE selector offers the possibility to choose from two different angles and also allows the columns to be horizontally mounted:
• 110°H x 15°V (narrow), 110°H x 40°V (wide) for the CLA803T model.
• 110°H x 25°V (narrow), 110°H x 50°V (wide) for the CLA403T model.
To install multiple speakers at 0° use the NARROW mode. To install the speaker horizontally, WIDE mode is recommended.
CAUTION: After making the connections and necessary adjustments, it is STRICTLY NECESSARY to reposition the protective casing (E).
17
To connect the speakers VERTUS CLA 403T and CLA 803T in an EVAC emergency evacuation system, use a CEI 20-105 approved cable. To
install the speaker outdoors, it is STRICTLY NECESSARY to use a cable with overall diameter 6-9mm in order to guarantee the system's
impermeability (CAUTION: tighten the cable gland properly).
To make a LINK, use a PG9 cable gland in a material with self-extinguishing rating 94V0 and protection rating IP68.

Parallel connection
The impedances are divided.
The 4 x 16Ω speakers can be connected to an
amplifier that manages 4Ω connections.
Series connection
The impedances are added up.
The 4 x 4Ω speakers can be connected to an
amplifier that manages 16Ω connections.
CONNECTION MODES
In the series connection, whatever the impedance of each speaker, the total
impedance results from the sum of all the impedances. Anyway, using sound
speakers with equal impedance and power is recommended.
Constant impedance outputs are generally used in the case of lines with a small
number of speakers having a certain power and being placed at a minimum distance
from the amplifier. Speaker connection will be a combination of connection in parallel
and series connection, so to bring loudspeakers total impedance to a value which is
not critical for the amplifier. In the series connection the positive lug shall be
connected to the negative lug of the following speaker. In the connection with
constant impedance it is always recommended that speakers total power is higher
than the power supplied by the amplifier.
If in the connection with constant impedance the volume of one or more speakers
needed to be set independently or also if any speaker needed to be switched off, the
use of attenuators keeping impedance constant is required.
SPEAKERS CONNECTION
Constant impedance speaker systems
This connection system implies that each speaker is equipped with its own line
transformer. The amplifier shall be equipped with 100V / 70V constant voltage
outputs.
Constant voltage speaker systems
SPEAKERS CONNECTION
All the constant voltage outputs (100V/70V) of a single amplifier can be connected at
the same time, provided that amplifier's rated power remains equal or higher to the
sum of the power of all the speakers installed on each output line.
The loudspeakers connected in parallel to amplifier's output will make system
expansion easier, if required, by simply shunting from any of the previously installed
speakers. Similarly, the loudspeakers which are not necessary anymore can be
removed. Matching the "phase" is necessary both in the connection of each speaker
to its own transformer and in the connection in parallel of the speakers.
Using the following formula: P=V²/Z with V being 100/70V and Z being speaker's
transformer primary impedance any power applied to each speaker can be
calculated. If, instead, you know the voltage (100V/70V) and the rated power (or
powers) of the transformer and you want to calculate transformer impedance, the
following formula applies: Z=V²/P.

BEFORE 5 speakers were connected to the system for a total of
55W. The selected amplifier was 60W.
AFTER Speakers were added and removed from the system.
The total requested power is now 87W.
In this case it is sufficient to change the amplifier,
but the system (in terms of cables) will remain unaltered.
