4.4 Operation
Operation of the VERA S30 speaker requires a DSP-Controller. For this purpose, only presets
developed by TW AUDiO are recommended. The TW AUDiO 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 8.
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 TW AUDiO preset can destroy the speaker.
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 S30 loudspeaker can be found in section 3.2 (“Connection dia-
gram”) on page 8.
The internal wiring of the VERA S30 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
In Cardio Setup mode, the sound radiated toward the rear is reduced. Ensure that you have
selected the correct preset for this setup. Incorrect connection results in a significant change
in the loudspeaker sound characteristics and may cause damage.
NOTE
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.
