VERA S33 Operating Manual

VERA S33 Operating Manual
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 15 dB over the entire bass spec-
trum. The end-fire mode is optimized for maximum sound pressure at the front with si-
multaneous 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
VERA S33. Featuring the same system width and a compatible rigging mechanism, the
VERA S33 can be inconspicuously integrated in the VERA36 array.

VERA S33 Operating Manual
1. Safety | Intended use
Please adhere to the following safety instructions to avoid risks when operating the loud-
speakers.
The VERA S33 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.
TW AUDiO GmbH shall not be held liable for any damage that ensues from unintended
use.
WARNING
Loudspeakers generate an electromagnetic field. Persons with pacemakers are not per-
mitted to remain in the immediate vicinity of loudspeakers as the electromagnetic fields
can cause pacemakers to malfunction.
WARNING
slings, etc.). Multiple people may be required depending on the situation.
Ensure that the units are in a stable position and are firmly attached. A falling loud-
speaker 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 appli-
cable safety regulations.
NOTE
When using the loudspeakers, ensure that they are not exposed to the following ambient
conditions:
• Direct sunlight
• Moisture
• Jolting
•Dust
WARNING
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 approx. 90 dB SPL can lead to long-term hearing im-
pairment.
NOTE
Avoid:
• Feedback
• Distorted signals (clipping)
• Peaks that result when devices are switched on or hot plugged and unplugged.
These signals can lead to loudspeaker overload.
When working with heavy loads over 20 kg [44,09 lbs], use suitable aids (dollies, hoisting

VERA S33 Operating Manual
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.
WARNING
Ensure that the loudspeaker is not exposed to permanent thermal overloads. This may
cause a fire and result in serious personal injury and property damage.
NOTE
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 data carriers, EC cards
and CRT displays. A distance of approx. one meter is sufficient to avoid damage.
NOTE
Check loudspeakers and accessory parts regularly for visible wear. This is essential to
ensure fault-free operation on a permanent basis. Replace worn parts promptly. Spare
parts can be obtained from TW AUDiO.

VERA S33 Operating Manual
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 Cardioid
When the cardioid preset is selected, the 15" cone driver (rear) is phase-shifted and
time-aligned relative to the 18" cone driver (front). This creates maximum cancellation
behind the loudspeaker (>15 dB front/back ratio in a free field, averaged across the fre-
quency response). At the front, partial summation leads to higher sound levels.
Figure 2.2.1 - Cardioid frequency response
2.2.1 Endfire
When the endfired preset is selected, the 18" cone driver (front) is in-phase and time-
aligned relative to the 15" cone driver (rear). This creates maximum summation in front
of the loudspeaker and higher sound levels compared to the cardioid preset. At the
back, partial cancellation leads to sound attenuation (>10 dB front/back ratio in a free
field, averaged across the frequency response).

4. Setting up the loudspeaker
The VERA S33 loudspeaker is designed for suspended and standing, vertical operation.
A variety of accessories is available from TW AUDiO to securely attach the loudspeaker,
e.g. on stands or suspended from trusses and motor lifts. Horizontal operation is not in-
tended.
To create a cable connection with an amplifier rack from TW AUDiO, proceed as follows.
The correct presets need to be selected for the cable connections.
4.1 Setup
WARNING
Ensure that the loudspeakers are securely attached to prevent personal injury and prop-
erty damage. Secure stacked loudspeakers properly so that they can be tipped by 10° in
any direction without toppling.
NOTE
TW AUDiO recommends using only the accessories specified by TW AUDiO to install
and secure the loudspeakers.
4.2 Connecting cables
NOTE
Ensure that the cable cross section is sufficiently large (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 the polarity (+/-) and pin as-
signment (1/2) are correct. Incorrect connection results in a significant change in the
loudspeaker sound characteristics and may damage the compression driver.
The pin connections of the VERA S33 loudspeaker can be found in section 3.2 “Wiring
diagram” on page 5.
The two speakON NL4 connectors on the back of VERA S33 can be used to link multi-
ple loudspeakers on a single amplifier output. Note that parallel connection reduces the
total impedance (Ω) seen by the amplifier.
The total impedance must never drop below the minimum loudspeaker impedance.

VERA S33 Operating Manual
TW AUDiO recommends operating the VERA S33 loudspeaker with DSP controller.
TW AUDiO only recommends using presets developed by TW AUDiO. The TW AUDiO
system racks are ideal for this purpose.
4.3 Operation
NOTE
Ensure that the right preset is loaded before connecting the loudspeaker with the ampli-
fier.
Operating with an incorrect preset can damage parts of the loudspeaker.
NOTE
Ensure that the amplifier is properly sized according to requirements. Undersizing or
oversizing may damage the loudspeaker.
Please note the technical data in section 3.1 “Data sheet” on page 5.

5. Transport and storage
NOTE
four people are needed to move and transport the unit.
To enable a single person to transport up to two VERA S33 loudspeakers, TW AUDiO
recommends using the quad dolly QDB30.
When transporting and storing the unit, it is important to ensure that the finish 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 ade-
quately protect the sensitive speaker membranes.
In addition, appreciable dust deposits may considerably impair the functionality of a
loudspeaker 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:
• QDB30 (quad dolly)
• Cover2S33 (protective cover)
The original packaging is unsuitable as permanent storage and transport packaging.
Because the VERA S33 loudspeaker weighs considerably more than 60 kg [132,3 lbs],
