Introduction
Thank you for choosing a high-quality product “MADE IN GERMANY” from TW AUDiO.
The VERA20 loudspeaker is equipped with two 10” chassis for the low-mid frequencies and
a waveguide with a 1.4” mid-high compression driver. Compared with typical double
8” systems, the VERA20‘s two 10” drivers are capable of reproducing up to 6 dB more
output in the low-mid frequency range with lower distortion.
Thanks to the loudspeaker’s width (only 60 cm / 23.62 inches) and height (28 cm /
11.02 inches), vertical arrays of up to 24 elements may be constructed.
The newly developed 1.4” compression driver and waveguide provides smooth and accurate
midrange performance for natural vocal and music reproduction. The low frequency
crossover point around 1 kHz guarantees precise and uniform coverage even in the sensitive
transition range. The extraordinarily fast transient response ensures that high frequency
reproduction is detailed and crisp.
The VERA20 implements an outstandingly innovative rigging hardware, allowing
straightforward, fast and cost-efficient setup and dismounting by just one technician. A
special feature is logarithmic scaling of the intermediate angles between angles. This allows
for angle adjustment of less than one degree to achieve more accurate directivity of upper
array elements over longer distances.

1. Safety | Intended use
Please adhere to the following safety instructions to avoid risks when operating
loudspeakers.
The VERA20 loudspeaker was developed for professional use in 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.
Damage caused by improper use is not covered by TW AUDiO.
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.
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.
When working with heavy loads over 20 kg [44,09 lbs.], use suitable aids (dollies, hoisting
slings, etc.). Multiple persons 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 setting up loudspeakers, ensure that they are not exposed to the following ambient
conditions:
Direct sunlight
Humidity
Jolting
Dust
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 approximately 90 dB SPL can lead to long-term hearing
impairment.
Avoid:
• Feedback
•Distorted signals (clipping)
• Peaks resulting from switching on devices, plugging in devices or unplugging devices
during operation.
Such signals can lead to loudspeaker overload.

Operation manual VERA20

Ensure that the loudspeaker is not exposed to permanent thermal overloads. Thermal
overloads may cause a fire and result in serious personal injury and property damage.
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.
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 storage media, magnetic stripe cards
such as debit cards and CRT displays. A distance of approximately one meter is sufficient to
avoid damage.
Check loudspeakers and accessory parts regularly for visible wear. This is essential to ensure
continuing fault-free operation. Worn parts should be replaced immediately. Spare parts are
available from TW AUDiO.

4. Setup
4.1. VERA20 Setup
The VERA20 speaker has been designed for horizontal operation in stacked and flown
vertical arrays. TW AUDiO offers various accessories for this application, such as
VERA RF600, SFV20, GSP20, etc.
Make sure the speakers are securely fastened to prevent personal injury and property
damage. Secure stacked loudspeakers properly so that they can be tilted by 10° in any
direction without toppling.
TW AUDiO recommends using only the accessories specified by TW AUDiO for securing
and mounting loudspeakers.
4.2. Rigging VERA20
VERA20 series line arrays can include VERA20 and/or VERA S32 or VERA S17 loudspeakers.
Please note that multiple VERA20 loudspeakers have to be connected to each other
mechanically. To connect speakers to each other, use the front and rear rigging tracks on
the left and on the right side (see Figure 2.1 - Position 4) and the rear rigging (see Figure
2.1 – Position 11). The rear rigging is an integral part of the VERA20 loudspeaker, and its
components can be unfolded or moved.
Further information on system assembly and disassembly can be found on the TW AUDiO
website.
Ease Focus simulation software can be used to plan VERA20 line arrays. Ease Focus is
available as a free download from the TW AUDiO website at www.twaudio.com.

4.3. Exchanging the horn flanges
Depending on the product version, the loudspeaker is shipped with either 80° or 120° horn
flanges (see chapter 2.2) installed. For applications that require a different horizontal
coverage, it may be advantageous to change the horn flanges. To do so, proceed as follows.
1. Place the VERA20 loudspeaker on its back, with the speaker grille facing up. The rear
rigging lever must be folded inward. Make sure to place the speaker on a clean, non-
slippery surface. To secure the speaker against lifting and slipping, ask a second
person for assistance.
2. To remove the speaker grille a TX25 Torx wrench is required. Use it to remove the
four mounting screws on the left and right side of the speaker housing.
3. Loosen the two screws on each horn flange.
4. Carefully pull the horn flanges upwards.
5. Carefully insert the new horn flanges. Screw them to the housing.
Take care not to damage the chassis with the screws.
6. Reattach the grille and screw it tight.
4.4. Operation
A VERA20 loudspeaker can only be operated with a DSP controller. TW AUDiO only
recommends using presets developed by TW AUDiO. The TW AUDiO system racks are ideal
for this purpose.
Before connecting the loudspeaker to the amplifier, ensure that the right preset has been
selected.
Using the wrong preset or a preset not provided by TW AUDiO preset can destroy the
speaker.
Make sure that the amplifier’s specifications meet the requirements. Using an amplifier that
doesn’t meet the specifications can destroy the loudspeaker.
Please note the technical data in section 3.1 on page 9.

4.5. Connecting cables
Ensure that the cable cross sectional area is sufficient (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 polarity (+/-) and pin
assignment (1/2) are correct. Incorrect connection can lead to a significant change in the
loudspeaker’s sound characteristics and may damage the compression driver.
The pin connections of the VERA20 loudspeaker can be found in section 3.2 (“Wiring
diagram”) on page 9.
The two connectors on the back of the VERA20 loudspeaker make it possible to connect
several loudspeaker units in parallel.
Please note that parallel connections will decrease the total impedance of your loudspeaker
configuration.
The total impedance and the resulting power of the speaker configuration must match the
output power of the amplifier.

Operation manual VERA20

5. Transport and Storage
Due to the VERA20 loudspeaker weighing over 20 kg [44,09 lbs.], two persons are required
to handle and transport the unit.
To enable a single person to transport up to four VERA20 loudspeakers, TW AUDiO
recommends using the VERA DLV20 dolly.
Ensure that the front grille of the loudspeaker is not damaged during transport and storage.
Moisture can penetrate 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, larger dust deposits can significantly affect the functionality of a speaker
membrane. For this reason, the product should be transported and stored in a safe, careful,
dry and largely dust-free manner.
The following transport and storage accessories are available from TW AUDiO:
VERA DLV20 (Dolly)
Cover4V20 (Protective cover)
The original packaging is not suitable as permanent storage and transport packaging.
