Operation manual VERA S33

Introduction
Thank you for choosing a high-quality product “MADE IN GERMANY” from TW AUDiO.
The VERA S33 is no normal subwoofer. It is literally pointing the way.
Its special feature is an 18“ speaker at the front and a 15“ speaker at the back. With bi-amp
operation and the respective presets, different dispersion characteristics can be produced.
The cardioid mode is optimized for maximum attenuation of the rearward sound dispersion,
achieving attenuation greater than 15dB over the entire bass spectrum. The end-fire mode
is optimized for maximum sound pressure at the front with simultaneous partial reduction
at the rear. Because of their directionality, basses sound much more concrete and musical,
especially in venues with a lot of reverb.
It goes without saying that a wide range of different setups can be achieved with the VERAS33.
Featuring the same system width and a compatible rigging mechanism, the VERA S33 can
be inconspicuously integrated in the VERA36 array.

1. Safety | Intended use
Please adhere to the following safety instructions to avoid risks when operating loudspeakers.
The VERA S33 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 20kg (44,09lbs.), use suitable aids (dollies, hois-
ting 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

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 S33 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.

4.1 Setup
The VERA S33 loudspeaker is designed to be used as a single loudspeaker as well as for array
operation.
TW AUDiO recommends using only the accessories specified by TWAUDiO for securing and
mounting loudspeakers.
NOTE
Make sure the speakers are securely fastened to prevent personal injury and property damage.
WARNING
4. Commissioning
4.2 M20 pole mount flange
Make sure that all system structures are located on a firm, level surface and that the surface
can bear the total weight!
WARNING
For all system components mounted on top of the M20 pole mount flange, observe the res-
pective operating instructions!
Also be sure to observe all of the following warnings:
Make sure that the maximum load of 50kg / 110lbs for the M20 pole mount flange is not
exceeded! Figure 2.1 – Item 2.
WARNING
Make sure that no unauthorized persons can access the system structures!
Cordon off the area professionally!
WARNING
The M20 pole mount flange (figure 2.1- item 2) is not designed for side forces once mounted
– do not apply any pressure from the sides.
Make sure that no external forces are applied to the system structures. No objects or persons
should lean against the structures, no objects should be thrown against them. If pressure is
applied on the flange the loudspeaker may be damaged or falling over.
