Introduction
Thank you for choosing a high-quality product “MADE IN GERMANY” from TW AUDiO.
The VERA S32i is a compact, flyable subwoofer belonging to the VERA20i series. It is equip-
ped with an 18” driver in the front and a 14” driver rearwards. Both long throw high-perfor-
mance drivers are optimally aligned. Various operating modes and the resulting coverage
variations allow for extremely flexible solutions. Depending on the selected preset, it can be
used in Cardioid, Endfire or Omni mode.
Cardioid mode is optimized for maximum attenuation of the rearward sound dispersion,
achieving attenuation greater than 15dB over the entire frequency range. The end-fire mode
is optimized for maximum sound pressure at the front while also providing partial rearward
sound dispersion.
The advantages are obvious: Thanks to directivity control, subwoofer performance is more
solid and musical, especially in environments with significant natural reverb. Performers on
stage and those behind the stage are spared from excessive bass levels.
The compact and appealing design of the enclosure allows a subtle presentation of the
VERA S32i. Especially when sightlines have to be considered or an array needs to be fitted
unobstrusively within the architectural surrounding.
The fully integrated, nearly invisible installation four-point rigging hardware support the discreet
optical aspect. A special feature is the logarithmic scaling of the intermediate angles between
angles. It enables angles smaller than one degree to achieve a more accurate directivity of
the upper array elements over a longer distance. In addition costs for expensive pins and
additional frames between subwoofer and tops do not apply.

cedures and hand over this assembly guide. If you require additional copies of this manual,

1. Safety | Intended use
Please adhere to the following safety instructions to avoid risks when operating loudspeakers.
The VERA S32i 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 permis-
sible.
Damage caused by improper use is not covered by TW AUDiO.
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 (44 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 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.
WARNING
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 90dBSPL can lead to long-term hearing impairment.
WARNING
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.
WARNING
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 TWAUDiO.

In Cardioid mode, the focus is on maximum sound pressure reduction behind the loudspeaker
setup, with partial forward-facing level addition.
The rear speaker produces an inverted signal to cancel out sound components on the back.
This results in a sound pressure level reduction of about 20 dB over a wide frequency range.
Depending on the distance between the loudspeakers and their transit time difference, there
will be a frequency-dependent sound pressure level addition of up to 3 dB in front of the
loudspeaker arrangement. By adjusting the transit time difference between the two individual
drivers, a different dispersion pattern – e.g. hypercardioid – can be achieved.
2.2 Operation modes
The VERA S32i can be operated in one of two modes. The operating mode is selected by
choosing the preset in the system amplifier.
2.2.1 Cardiod
In Endfire mode, the focus is on maximum forward-facing sound pressure level addition, with
partial reduction to the rear.
To achieve this, the front loudspeaker’s signal is delayed so that its signal is in phase with the
rear loudspeaker in the direction of sound. This results in a sound pressure level addition of
about 6 dB over a wide frequency range. Depending on the speaker distance, there is a fre-
quency-dependent sound pressure level reduction on the rear side. The strongest cancellation
is to be expected at the frequency whose wavelength corresponds to four times the driver
spacing.
2.2.2 Endfire
Never change the preset during active operation. Operating with an incorrect preset can
damage parts of the loudspeaker.

4.4 Operation
Operation of the VERA S32i 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.
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.
NOTE
Before connecting the loudspeaker to the amplifier, ensure that the right preset has been
loaded.
Using the wrong preset or a preset not provided by TWAUDiO preset can destroy the speaker.
NOTE
4.3 Connection options
The VERA S32i loudspeaker is equipped as standard with the i-series screw terminal.
As options there can be mounted a panel with cable gland (CG option) or a panel with two
built-in speakON® jacks (SO option).
Furthermore, a blind cover option is available.
All connection options are only available in black colour.
NOTE
More information about the different connection options can be found in the respective opera-
ting instructions in the download area on the homepage of TWAUDiO.
NOTE

4.5 Connecting the cable
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 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 driver.
The pin connections of the VERA S32i loudspeaker can be found in section 3.2 (“Connection dia-
gram”) on page 9.
The internal wiring of the VERA S32i loudspeaker allows for parallel connection of multiple
loudspeaker units.
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.
NOTE

5. Transport and Storage
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.
NOTE
Due to the VERA S32i loudspeaker weighing over 40 kg [88 lbs.], three persons are required
to handle and transport the unit.
