Exchanging the horn flanges
Depending on the product version, the loudspeaker is shipped with either 80° or 120° horn
flanges (see chapter 2.2) installed. For applications that require a different horizontal
coverage, it may be advantageous to change the horn flanges. To do so, proceed as follows.
1. Place the VERA20 loudspeaker on its back, with the speaker grille facing up. The rear
rigging lever must be folded inward. Make sure to place the speaker on a clean, non-
slippery surface. To secure the speaker against lifting and slipping, ask a second
person for assistance.
2. To remove the speaker grille a TX25 Torx wrench is required. Use it to remove the
four mounting screws on the left and right side of the speaker housing.
3. Loosen the two screws on each horn flange.
4. Carefully pull the horn flanges upwards.
5.
Carefully insert the new horn flanges. Screw them to the housing.
Take care not to damage the chassis with the screws.
6.
Reattach
the
grille
and screw it tight.

Operation
A VERA20 loudspeaker can only be operated with a DSP controller. TW AUDiO only
recommends using presets developed by TW AUDiO. The TW AUDiO system racks are ideal
for this purpose.
Before connecting the loudspeaker to the amplifier, ensure that the right preset has been
selected.
Using the wrong preset or a preset not provided by TW AUDiO preset can destroy the
speaker.
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.
