Introduction
Named for the VERtical Arrays in which these systems are used, our VERA line array solutions
are transforming large-format sound reinforcement, led by the VERA10 series. The series
is based on the VERA10 top, a compact line array element measuring just 50 cm (19.7“) in
width yet scalable up to an array length of 18 elements.
This means that the VERA10 is arguably the most versatile component in the whole TW AUDiO
range – with just two tops, a core VERA10 system can be created to deliver uncompromising
high quality sound reproduction in an extremely compact format. Yet VERA10 has been desi-
gned and developed to deliver so much more.
The starting point was the desire to provide our customers with a single, flexible system that
can be extended with a multitude of additional components to meet their specific require-
ments. Everything from gala events, touring roadshows, through to large, open-air or stadium
rock concerts can be served with an investment in VERA10.
The modular design of the VERA10 series offers countless possibilities for every user.
Whether flown or stacked, VERA10 offers you a fully flexible solution for delivering the very
best in audio reproduction for every event, from small gigs to mid-sized indoor shows and
even open-air concerts.
Within the VERA10 top element itself is a single 10“ loudspeaker and two 1“ high frequency
drivers. Our compression chamber phase plug is positioned in front of the 10“ chassis while
VERA10‘s optimised waveguide is coupled to the HF-drivers, all combining to deliver striking
tonal depth with sparkling high end in 10 degree vertical dispersion.
Exchanging the mid-high horn allows the horizontal dispersion to be set to either
80 or 120 degrees. Additional versatility is achieved by the addition of the optional PWVERA10
passive crossover which makes it possible to switch between passive operation on a single
amplifier channel and standard bi-amped, two-way active operation.

NOTE
NOTE
Please adhere to the following safety instructions to avoid risks when operating loudspeakers.
Note the operating modes described in this operating manual. Other uses are not permis-
sible.
Damage caused by improper use is not covered by TWAMBO.
Loudspeakers generate an electromagnetic field. Persons with pacemakers are not permit-
ted to remain in the immediate vicinity of loudspeakers as the electromagnetic fields can
cause pacemakers to malfunction.
When working with heavy loads exceeding 20 kg (44lbs.), 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 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 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 pres-
sure levels. These loudspeaker systems are capable of endangering your health. Sound levels
beginning as low as approximately 90dB SPL can lead to long-term hearing impairment.
Avoid:
• Feedback
• Distorted signals (clipping) and
• Peaks resulting from switching on devices, plugging in devices or unplugging devices during
operation.
Such signals can lead to loudspeaker overload and ultimately to loudspeaker failure.

The VERA10 loudspeaker comes in four different variants. These are differentiated by their
horizontal coverage (80° or 120°) and are further subdivided into VERA10A (BIAMP model)
and VERA10P (PASSIVE model).
The VERA10 loudspeaker can be equipped with either an 80° × 10° horn or a 120° × 10° horn.
The degrees refer to the horizontal and vertical radiation angles. The VERA10 horn variant can
be identified by the legend printed on the horn (see figure 2.2).
The horn can be exchanged for the other type at any time. See section 4.2 „Exchanging the
horn“.
2.2 Variants
Figure 2.2 - VERA10 horn variants
2.2.1 Horn - horizontal coverage 80° / 120°
2.2.2 VERA10A / VERA10P models
The standard model of the VERA10 loudspeaker is the VERA10A, which can only be opera-
ted in the „biamped“ mode. It is supplied with a standard connection panel and requires two
amplifier channels for operation. The compression driver and cone driver are separated by the
DSP of the amplifier.
The VERA10P model can additionally be switched to the „passive“ mode. This enables opera-
tion with only one amplifier channel, for which the enclosure contains a passive crossover. The
built-in passive crossover features two selector switches described in section 2.3.

The passive version (VERA10P) features two selector switches on the rear (figure 2.3.1 and
2.3.2) for switching between two different operating modes and for attenuating the high fre-
quency range (see figure 2.1, no. 16).
In the „PASSIVE“ mode, the loudspeaker is operated on a passive audio crossover with a
single amplifier channel.
2.3 Operating modes
Figure 2.3.1.2 - Operating mode „BIAMPED“
2.3.1 Horizontal selector switch
In the „BIAMP“ mode, the internal passive crossover bypasses the signal path and the indivi-
dual routes of the loudspeaker must be driven separately by two DSP channels.

WARNING
4.2 Exchanging the horn
Depending on the variant, either the 80° × 10° or the 120° × 10° horn (see section 2.2.1) is
built into the VERA10 loudspeaker. For some applications, it may be advantageous to exch-
ange the horn for the other variant in order to change the horizontal coverage. Proceed as
follows.
1. Place the VERA10 loudspeaker on its back with the front grill facing up. Ensure that you
are working on a clean and non-slip surface. To secure the speaker against lifting and
slipping, ask a second person for assistance.
2. To remove the front grill a 3mm hex key is required. Use it to remove the four mounting
screws on the left and right side of the speaker enclosure. (two on every side).
3. Release the four screws of the horn using a 3 mm hex key.
4. Pull the horn upward out of the loudspeaker enclosure.
5. Check that the sealing lip between the waveguide and horn is properly seated.
6. Insert the new horn in the opening. Screw it onto the enclosure using mediumstrength
thread locker.
7. Screw the front grill back on.
Make sure that all system structures are located on a firm, level surface and that the surface
can bear the total weight!
Make sure the speakers are securely fastened to prevent personal injury and property damage.
Secure stacked loudspeakers properly so that they can be tipped by 10° in any direction
without toppling.
TW AUDiO recommends using only the accessories specified by TWAUDiO for securing and
mounting loudspeakers.

4.3 Operation
4.4 Connecting the cable
Operation of the VERA10A speaker requires a DSP-Controller. For this purpose, only presets
developed by TW AUDiO are recommended. The TWAUDiO system racks are ideally suited
for this purpose.
Please note the technical data in section 3.1 on page 11.
NOTE
NOTE
Before connecting the loudspeaker to the amplifier, ensure that the right preset has been
loaded.
Using a wrong, out dated or a preset not provided by TWAUDiO can lead to destruction of
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.
The pin connections of the VERA10 loudspeaker can be found in section 3.2 (“Connection dia-
gram”) on page 11 and 12.
The internal wiring of the VERA10 loudspeaker allows for parallel connection of multiple
loudspeaker units.
NOTE
To create a cable connection with an amplifier rack from TW AUDiO, proceed as follows.
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 TWAUDiO.
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 driver.
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.

5. Transport and storage
NOTE
• VERA DL10 (dolly for up to 12 VERA10)
• CaseVERA10 (flight case for 2x 2 VERA10 elements)
To transport the unit with a single person, TW AUDiO recommends using the VERA DL10 dolly.
Alternatively, the VERA10 can also be transported in the CaseVERA10 flight case.
When transporting and storing the unit, it is important to ensure that the surface 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 loudspe-
aker 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:
The original packaging is unsuitable as permanent storage and transport packaging.
