VERA20 Operation manual

Operation manual VERA20

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.

Operation manual VERA20

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 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.

When working with heavy loads over 20 kg [44,09 lbs.], use suitable aids (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 operated 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 resulting from switching on devices, plugging in devices or unplugging devices

during operation.

Such signals can lead to loudspeaker overload.

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 damage.

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.

2.2. Variants – Horn flanges horizontal coverage 80° / 120°

The VERA20 loudspeaker can optionally be equipped with 80° or 120° horn flanges. The

angle specification refers to horizontal coverage. Check the rear rigging to identify the

VERA20 variant.

The factory installed horn flange type is marked on the VERA20’s rear rigging. Depending

on your application, it may be advantageous to change the horn flange. In this case, the

identification mark on the rear rigging should also be changed. The factory marking can be

removed using acetone.

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 are 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 specified 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 found 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.
