TW AUDiO VERA36 10 Inch 3-way Compact Pa Audio User Manual

TW AUDiO VERA36 10 Inch 3-way Compact Pa Audio

Introduction

Thank you for choosing a high-quality product “MADE IN GERMANY” from TW AUDiO. The intrinsic qualities of the VERA36 speak for themselves with no fewer than six drivers working within the compact confines of the enclosure. The central mid-range horn is driven by two 8“ cone speakers while the mid-high frequency unit comprises two 1.4“ compression drivers plus a purpose-developed waveguide, coaxially positioned in the center. The result is a vertical dispersion of 10 degrees with horizontal dispersion across either 80 or 120 degrees as required. Supplementing the low-mid range are two 10“ long excursion bass speakers. Below 400 Hz, all four cone speakers work in tandem to deliver vast reserves of low-mid punch. All of that leading to our user‘s experience that VERA36 can compete with much bigger double 12“ systems and more besides. But for a contemporary loudspeaker system to achieve real success, impressive performance alone just isn‘t enough. Today, systems must be easy to operate, quick to rig and simple to transport, and in all of these areas VERA36 excels. Setup times are dramatically reduced cortesy of a newly developed, fully integrated, three-point rigging system incorporating an innovative mechanism with logarithmically stepped splay angles, enabling optimal array cur-ving and precise directional targeting. The combination of TW AUDiO‘s deep expertise and the precision of the VERA36 hardware equals coverage right to the back rows of even a large venue. No matter whether you fly the system straight from the dolly, rig from the floor or build as a ground-stack, every variation is swiftly and safely achievable. Having the same width as the VERA S33 and equipped with the same rigging, VERA S33 subwoofers can easily and unobtrusively be integrated into VERA36 arrays.

Safety Intended use

Please adhere to the following safety instructions to avoid risks when operating loudspeakers. The VERA36 loudspeaker was developed for use in professional sound systems. The loudspe-aker may only be used by trained and qualified personnel. Note the operating modes described in this operating manual. Other uses are not permis-sible. Damage caused by improper use is not covered by TW AUDiO. 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.

WARNING

• 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:

NOTE

• 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 90 dB SPL 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.

WARNING

• 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 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.

Commissioning

Setup

The VERA36 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 loudspeaker.

WARNING

• 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.
• TW AUDiO recommends using only the accessories specified by TW AUDiO for securing and mounting loudspeakers.

Rigging VERA36

• VERA36 series line arrays can include VERA36 and/or VERA S33 loudspeakers.
• Note that the VERA36 loudspeakers are mechanically connected. This is done via the quick and easy 3-point rigging.
• Also note that the VERA S33 loudspeakers are mechanically connected via 4-point rigging.
• Please refer to the VERA RF900 and SFV36 manuals for operating modes and set-up options.
• EASE Focus simulation software can be used to plan VERA36 line arrays. EASE Focus is avai-lable as a free download from the TW AUDiO website at www.twaudio.com.

Changing the high frequency unit

Depending on the variant, the 80° or 120° high frequency unit (see capter 2.3 – page 9) is installed in the loudspeaker. For some applications, it may be advantageous to exchange the high frequency unit for the other variant in order to change the horizontal coverage. Proceed as follows:

1. Place the VERA36 loudspeaker on its back with the front grill facing up. Ensure that the working surface is clean with a non-slip finish. To secure the speaker against lifting and slipping, ask a second person for assistance.
2. Remove the four grill mounting screws on the left and right of the speaker enclosure. Use a TX25 hexalobular key.
3. Carefully unplug the connector from the high frequency unit.
4. Loosen the two screws of the high frequency unit (see figure 4.3 – S1 and S2). Use a tool with SW8.
5. Carefully pull the high frequency unit upward out of the loudspeaker enclosure.
6. Carefully guide the new high frequency unit into the guide groove until it hits the rear. Screw it onto the enclosure.
7. Reconnect the high frequency unit into the connection plate.
8. Screw on the front grill.
9. Change the marking for the installed high frequency unit on the rear rigging.

Operation

Operation of the VERA36 loudspeaker requires a DSP-Controller. For this purpose, only pre-sets developed by TW AUDiO are recommended. The TW AUDiO system racks are ideally suited for this purpose.

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.
• 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 10.

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.

NOTE

• 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 VERA36 loudspeaker can be found in section 3.2 (“Connection dia-gram”) on page 10.
• The internal wiring of the VERA36 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.

Transport and Storage

Due to the VERA36 loudspeaker weighing over 20 kg [44 lbs.], two persons are required to handle and transport the unit. To enable a single person to transport up to six VERA36 loudspeakers, TW AUDiO recom-mends using the VERA DLV36.

NOTE

• When transporting and storing the unit, it is important to ensure that the surface and front grill of the loudspeaker are not damaged. Moisture can penetrate through 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, appreciable dust deposits may considerably impair the functionality of a loudspe-aker membrane. For this reason, the loudspeakers should be transported and stored in a safe, careful, dry and largely dust-free manner.
• The following accessory parts for transport and storage are available from TW AUDiO:
• VERA DLV36 (dolly)
• Cover4V36 (protective cover)

The original packaging is unsuitable as permanent storage and transport packaging.
