Introduction

Thank you for choosing a high-quality product “MADE IN GERMANY” from TW AUDiO.

The VERA20 loudspeaker is equipped with two 10” chassis for the low-mid frequencies and a waveguide with a 1.4” mid-high compression driver. Compared with typical double 8” systems, the VERA20‘s two 10” drivers are capable of reproducing up to 6 dB more output in the low-mid frequency range with lower distortion.

Thanks to the loudspeaker’s width (only 60 cm / 23.62 inches) and height (28 cm /

11.02 inches), vertical arrays of up to 24 elements may be constructed.

The newly developed 1.4” compression driver and waveguide provides smooth and accurate midrange performance for natural vocal and music reproduction. The low frequency crossover point around 1 kHz guarantees precise and uniform coverage even in the sensitive transition range. The extraordinarily fast transient response ensures that high frequency reproduction is detailed and crisp.

The VERA20 implements an outstandingly innovative rigging hardware, allowing straightforward, fast and cost-efficient setup and dismounting by just one technician. A special feature is logarithmic scaling of the intermediate angles between angles. This allows for angle adjustment of less than one degree to achieve more accurate directivity of upper array elements over longer distances.

1. Safety | Intended use

Please adhere to the following safety instructions to avoid risks when operating loudspeakers.

The VERA20 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.

Damage caused by improper use is not covered by TW AUDiO.

WARNING

Loudspeakers generate an electromagnetic field. Persons with pacemakers are not permitted to remain in the immediate vicinity of loudspeakers as the electromagnetic fields can cause pacemakers to malfunction.

When using a

nd assemblin

g TW AUDiO loudspeakers, only use materials specified by TW AUDiO. These tasks must be performed by qualified personnel. Adhere to the applicable safety regulations.

When working with heavy loads over 20 kg [44,09 lbs.], use suitable ai

ds (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 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 op

erated at high

sound pressure levels. These loudspeaker systems are capable of endangering your health. Sound levels beginning as low as approximately 90 dB SPL can lead to long-term hearing impairment.

Avoid:

• Feedback

•

Distorted signals (clipping)

• Peaks result

ing from switching on devices, plugging in devices or unplugging device

during operation.

Such signals can lead to loudspeaker overload.

Page 6

Operation manual VERA20

Ensure that the loudspeaker is not exposed to permanent thermal overloads. Thermal overloads may cause a fire and result in serious personal injury and property dama

ge.

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 TW AUDiO.

4. Setup

4.1. VERA20 Setup

The VERA20 speaker has been designed for horizontal operation in stacked and flown vertical arrays. TW AUDiO offers various accessories for this application, such as VERA RF600, SFV20, GSP20, etc.

Make sure the speakers ar

e securely fastened to prevent personal injury and property damage. Secure stacked loudspeakers properly so that they can be tilted by 10° in any direction without toppling.

TW AUDiO recommends using only the accessories sp

ecified by TW AUDiO for securing

and mounting loudspeakers.

4.2. Rigging VERA20

VERA20 series line arrays can include VERA20 and/or VERA S32 or VERA S17 loudspeakers.

Please note that multiple VERA20 loudspeakers have to be connected to each other mechanically. To connect speakers to each other, use the front and rear rigging tracks on the left and on the right side (see Figure 2.1 - Position 4) and the rear rigging (see Figure

2.1 – Position 11). The rear rigging is an integral part of the VERA20 loudspeaker, and its components can be unfolded or moved.

Further information on system assembly and disassembly can be foun

d on the TW AUDiO

website.

Ease Focus simulation software can be used to plan

VERA20 line arrays. Ease Focus is

available as a free download from the TW AUDiO website at www.twaudio.com.

4.3. 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, nonslippery 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 hous

ing.

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 cha

ssis with the screws.

6. Reattach the grille and screw it tight.

4.4. 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.

Page 12

Operation manual VERA20

4.5. Connecting cables

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 compression driver.

The pin connections of the VERA20 loudspeaker can be found in section 3.2 (“Wiring diagram”) on page 9.

The two connectors on the back of the VERA20 loudspeaker make it possible to connect several loudspeaker units in parallel.

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.

Page 13

Operation manual VERA20

5. Transport and Storage

Due to the VERA20 loudspeaker weighing over 20 kg [44,09 lbs.], two persons are required to handle and transport the

unit.

To enable a single person to transport up to four VERA20 loudspeakers, TW AUDiO recommends using the VERA DLV20 dolly.

Ensure that the front grille of the loudspeaker is not damaged during transport and storage. Moisture can penetrate 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, larger dust deposits can significantly affect the functionality of a speaker membrane. For this reason, the product should be transported and stored in a safe, careful, dry and largely dust-free manner.

The following transport and storage accessories are available from TW AUDiO:

 VERA

DLV20 (Dolly)

 Cover4V20 (Protective cover)

The original packaging is not suitable as permanent storage and transport packaging.
