VERA L24
Operating Manual
Operating Manual VERA L24
Introduction
Thank you for choosing a high quality product "MADE IN GERMANY" from TW AUDiO.
VERA L24 supports the low-mid performance of VERA10 arrays between 60 to 300 Hz.
Equipped with two 12" loudspeakers, the hybrid enclosure construction combines the
advantages of bass reflex and horn design, so that a single VERA L24 can give three or
four VERA10 elements a clear low-mid boost and plenty of punch.
The top side of the enclosure slopes down towards the back by 5° degrees allowing you
not only to integrate the L24 easily into VERA10 arrays but also to suspend it in a separate column next to a VERA10 array with adapted curvature.

Operating Manual VERA L24
1. Safety | Intended use
Please adhere to the following safety instructions to avoid risks when operating the loudspeakers.
The VERA L24 loudspeaker was developed for use in professional sound systems. The
loudspeaker may only be used by trained and qualified personnel.
Note the operating modes described in this operating manual.
Other uses are not permissible.
TW AUDiO GmbH shall not be held liable for any damage that ensues from unintended
use.
WARNING
Loudspeakers generate an electromagnetic field. Persons with pacemakers are not permitted to remain in the immediate vicinity of loudspeakers as the electromagnetic fields
can cause pacemakers to malfunction.
WARNING
When working with heavy loads over 20 kg [44,09 lbs], use suitable aids (dollies, hoisting slings, etc.). Multiple people may be required depending on the situation.
Ensure that the units are in a stable position and are firmly attached. A falling loudspeaker can result in serious personal injury and property damage.
When using and assembling TW AUDiO loudspeakers, only use materials specified by
TW AUDiO. These tasks must be performed by qualified personnel. Adhere to the applicable safety regulations.
NOTE
When using the loudspeakers, ensure that they are not exposed to the following ambient
conditions:
• Direct sunlight
• Moisture
• Jolting
•Dust
WARNING
Keep away from the immediate vicinity of loudspeakers that are operated at high sound
pressure levels. These loudspeaker systems are capable of endangering your health.
Sound levels beginning as low as approx. 90 dB SPL can lead to long-term hearing impairment.
NOTE
Avoid:
• Feedback
• Distorted signals (clipping)
• Peaks that result when devices are switched on or hot plugged and unplugged.
These signals can lead to loudspeaker overload..

Operating Manual VERA L24
Note that TW AUDiO does not provide a warranty for damage that can be attributed to
this type of overload and therefore cannot be held liable for any secondary damage.
WARNING
Ensure that the loudspeaker is not exposed to permanent thermal overloads. This may
cause a fire and result in serious property damage and personal injury.
NOTE
A permanent, magnetic field is present in the immediate vicinity of loudspeakers. Ensure
that objects which react sensitively to magnetic fields are not located in the immediate
vicinity of the loudspeaker. In particular, this applies to magnetic data carriers, EC cards
and CRT displays. A distance of approx. one meter is sufficient to avoid damage.
NOTE
Check loudspeakers and accessory parts regularly for visible wear. This is essential to
ensure fault-free operation on a permanent basis. Replace worn parts promptly. Spare
parts can be obtained from TW AUDiO.

4. Setting up
The VERA L24 loudspeaker is designed for suspended and standing operation. A variety of accessories is available from TW AUDiO to securely attach the loudspeaker, e.g.
on stands or suspended from trusses and chain/ motor hoists.
To connect the loudspeaker with an amplifier rack from TW AUDiO, proceed as follows.
The correct presets need to be selected for the cable connections.
4.1 Setup
WARNING
Ensure that the loudspeakers are securely attached to prevent personal injury and property damage. Secure stacked loudspeakers properly so that they can be tipped by 10° in
any direction without toppling.
NOTE
TW AUDiO recommends using only the accessories specified by TW AUDiO to install
and secure the loudspeakers.
4.2 Making cable connections
NOTE
Ensure that the cable cross section is sufficiently large (at least 1.5 mm²) to avoid power
losses. TW AUDiO recommends using the loudspeaker cables available from
TW AUDiO.
When connecting the cables to the loudspeaker, ensure that the polarity (+/-) and pin assignment (1/2) are correct. Incorrect connection results in a significant change in the
loudspeaker sound characteristics and may damage the compression driver.
The pin connections of the VERA L24 loudspeaker can be found in section 3.2 “Wiring
diagram” on page 4.
The two VERA L24 connection sockets on the back of VERA L24 can be used to link
multiple loudspeakers to a single amplifier output. Note that parallel connection reduces
the total impedance (Ω) seen by the amplifier.
The total impedance of loudspeakers connected in parallel must not drop below the minimum operating impedance of the amplifier.
6
Operating Manual VERA L24
TW AUDiO recommends operating the VERA L24 loudspeaker on a DSP controller.
TW AUDiO only recommends using presets developed by TW AUDiO. The TW AUDiO
system racks are ideal for this purpose.
4.3 Operation
NOTE
Ensure that the right preset was selected before connecting the loudspeaker with the
amplifier.
Operating with an incorrect preset can damage parts of the loudspeaker.
NOTE
Ensure that the amplifier is properly sized according to requirements. Undersizing or
oversizing may damage the loudspeaker.
Please note the technical data in section 3.1.“Data sheet” on page 4.

Operating Manual VERA L24
5. Transport and storage
NOTE
Because the VERA L24 loudspeaker weighs far more than 20 kg [44,09 lbs], two people
are needed to move and transport one.
To enable a single person to transport multiple VERA L24 loudspeakers, TW AUDiO
recommends using the VERA DL24 transport cart.
When transporting and storing the unit, it is important to ensure that the finish and front
grill of the loudspeaker are not damaged. Moisture can penetrate through exposed wood
surfaces and cause the wood to swell. A bent or broken front grill will no longer adequately protect the sensitive speaker membranes.
In addition, appreciable dust deposits may considerably impair the functionality of a
loudspeaker membrane. For this reason, the loudspeakers should be transported and
stored in a safe, careful, dry and largely dust-free manner.
The following accessory parts for transport and storage are available from TW AUDiO:
• VERA DL24 (transport cart for up to six VERA L24)
• BagL24 (carrying bag for two VERA L24)
• CaseL24 (flight case for four VERA L24)
The original packaging is unsuitable as permanent storage and transport packaging.
