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.

1. Safety | Intended use
The VERA10 loudspeaker was developed for use in professional sound systems. The
loudspeaker may only be used by trained and qualified personnel.
WARNING
WARNING
WARNING
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.

WARNING
NOTE
NOTE
Ensure that the loudspeaker is not exposed to permanent thermal overloads. Thermal over-
loads may cause a fire and result in serious personal injury and property damage.
Note that TWAMBO 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 TWAUDiO.

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.

Never change the operating mode while the loudspeaker is connected. In addition to setting
the switch, the corresponding preset on the amplifier must be changed.
Using a wrong, out dated or a preset not provided by TWAUDiO can lead to destruction of
the speaker.

The „High shelf attenuation“ vertical selector switch lowers the frequency range above 2kHz
independent of the VERA10P operating mode.
In the „0 dB normal operation“ mode, the frequency response is not attenuated above 2kHz.
In the „-6 dB short throw“ mode, the frequency response above 2 kHz is attenuated by 6 dB.
In the „-3 dB mid throw“ mode, the frequency response above 2 kHz is attenuated by 3 dB.
