Operation manual VERA20

Introduction

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”sys-

tems, the VERA20‘s two 10” drivers are capable of reproducing up to 6dB more output in the

low-mid frequency range with lower distortion.

Thanks to the loudspeaker’s width (only 60 cm / 23.62inches) and height (28cm / 11.02inches),

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 crosso-

ver point around 1kHz guarantees precise and uniform coverage even in the sensitive transi-

tion range. The extraordinarily fast transient response ensures that high frequency reproduc-

tion is detailed and crisp.

The VERA20 implements an outstandingly innovative rigging hardware, allowing straightfor-

ward, 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 adjust-

ment of less than one degree to achieve more accurate directivity of upper array elements

over longer distances.

1. Safety | Intended Use

The VERA20 loudspeaker was developed for professional use in sound systems. The loudspe-

aker may only be used by trained and qualiﬁed personnel.

WARNING

NOTE

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

Note the operating modes described in this operating manual. Other uses are not permis-

sible.

Damage caused by improper use is not covered by TWAMBO.

Loudspeakers generate an electromagnetic ﬁeld. Persons with pacemakers are not permit-

ted to remain in the immediate vicinity of loudspeakers as the electromagnetic ﬁelds can

cause pacemakers to malfunction.

When working with heavy loads exceeding 20 kg (44 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 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 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 pres-

sure levels. These loudspeaker systems are capable of endangering your health. Sound levels

beginning as low as approximately 90dBSPL can lead to long-term hearing impairment.

Avoid:

• Feedback

• Distorted signals (clipping) and

• Peaks resulting from switching on devices, plugging in devices or unplugging devices during

operation.

Such signals can lead to loudspeaker overload and ultimately to loudspeaker failure.

Operation manual VERA20

WARNING

NOTE

Ensure that the loudspeaker is not exposed to permanent thermal overloads. Thermal over-

loads may cause a ﬁre and result in serious personal injury and property damage.

Note that TWAMBO 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 TWAUDiO.

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 vari-

ant.

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 identiﬁ-

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

using acetone.

4.1 Setup

The VERA20 loudspeaker has been designed for horizontal operation in stacked and ﬂown

vertical arrays. TW AUDiO provides a wide range of accessories to securely attach the loudspe-

aker.

NOTE

WARNING

WARNING

4.2 Rigging VERA20

VERA20 series line arrays can include VERA20 and/or VERAS32 loudspeakers.

WARNING

NOTE

Note that the VERA20 loudspeakers are mechanically connected. This is done via the quick

and easy 3-point rigging.

Also note that the VERA S32 loudspeakers are mechanically connected via 4-point rigging.

Please refer to the VERARF600, SFV20 and GSP20 manuals for operating modes and set-up

options.

EASE Focus simulation software can be used to plan VERA20 line arrays. EASEFocus is avai-

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

TIP

Make sure that all system structures are located on a ﬁrm, level surface and that the surface

can bear the total weight!

Make sure the speakers are securely fastened to prevent personal injury and property damage.

Secure stacked loudspeakers properly so that they can be tipped by 10° in any direction

without toppling.

TW AUDiO recommends using only the accessories speciﬁed by TWAUDiO for securing and

mounting loudspeakers.
