    PowerCon NAC3FCB connector for AC loop thru allows up to 8 units when using a 230V version (see unit’s label)). Only use this equipment with an appropriate mains cord.

ON/OFE

• A sound system should be switched on sequentially. Switch on the self-powered units last in your sound system (switch on the subwoofer before the mid-high system). Switch on the sound sources such as CD players or turntables, then the mixer, then the processors, and finally the self- powered unit. If you have several units, it is recommended that you switch them on sequentially one at a time.
• Follow the inverse order when switching off, turning self-powered units off before any other element in the sound system.
• Disconnect the device by removing the mains connector from the mains socket. The mains connector and mains socket must always be freely accessible and never covered or blocked in any way. The mains cable can be detached from the device by disconnecting the standard PowerCon NC3FCA connector. Always disconnect the device by removing the mains connector from the mains socket before detaching the mains cable at the PowerCon NC3FCA connector. Power can be daisy chained via the NC3FCB output connector (see details on product label).
• IMPORTANT : Do not disconnect the unit while in use. Ensure that the device is disconnected from the mains by observing that the ON LED is turned off. Please note that the ON LED can stay on for several seconds after the mains power has been disconnected.

Overload LED indicator (Vantec 18A)
This device has an indicator (LIMIT LED) that lights when the signal is excessive. The indicator should not be lit continuously. This distorts the signal (quickly fatiguing your ears) and may damage the speakers. Therefore, it is recommended that you never work with this LED on; at most it should blink only occasionally.

Overload Screen indicators Vantec 12/15/215A)
In the main screen when input signal levels are too high on the left side the meters will display “input clip”.
If the input levels are in between the limits but the display evel gain is too much the right meter will

Equalization
The unit does not need extreme settings of equalization to produce quality sound. Avoid high levels of gain on the equalizers. Gain values above +3 dB on a console’s EQ are not recommended.

Overheating
This equipment does not normally overheat during normal conditions of use. When overheating occurs, the unit protects itself. You should then find out why and if necessary contact an authorised dealer for technical assistance.

Normally it is enough just to let the unit cool down after you have corrected the problem so that the system functions properly again.

Low mains voltage
If mains voltage falls below the shutdown voltage for the unit, it will stop playing. When acceptable levels are regained, the unit will switch back on automatically. Therefore the current consumed by a 115V version is double the 230V version to achieve the same acoustic power level.

TROUBLESHOOTING

RIGGING

Warnings

• This manual contains needed information for flying D.A.S. Audio cabinets, description of the elements and safety precautions. To perform any operations related to flying the system, read the present document first, and act on the warnings and advice given. The goal is to allow the user to become familiar with the mechanical elements required to fly the acoustic system, as well as the safety measures to be taken during set-up and teardown.
• Only experienced installers with adequate knowledge of the equipment and local safety regulations should fly speaker boxes. It is the user’s responsibility to ensure that the systems to be flown (including flying accessories) comply with state and local regulations.
• The working load limits in this manual are the results of tests by independent laboratories. It is the user’s responsibility to stay within safe limits. It is the user’s responsibility to follow and comply with safety factors, resistance values, periodical supervisions and warnings given in this manual. Product improvement by means of research and development is on going at D.A.S. Specifications are subject to change without notice.
• To this date, there is no international standard regarding the flying of acoustic systems. However, it is common practice to apply 5:1 safety factors for enclosures and static elements. For slings and elements exposed to material fatigue due to friction and load variation the following ratios must be met; 5:1 for steel cable slings, 4:1 for steel chain slings and 7:1 polyester slings. Thus, an element with a breaking load limit of 1000 kg may be statically loaded with 200 kg (5:1 safety factor) and dynamically loaded with 142 kg (7:1 safety factor).
• When flying a system, the working load must be lower than the resistance of each individual flying point in the enclosure, as well as each box. Hanging hardware should be regularly inspected and suspect units replaced if in doubt. This is important to avoid injury and absolutely no risks should be taken in this respect. It is highly recommended that you implement an inspection and maintenance program on flying elements, including reports to be filled out by the personnel that will carry out the inspections. Local regulations may exist that, in case of accident, may require you to present evidence of inspection reports and corrective actions after defects were found.
• Absolutely no risks should be taken with regards to public safety. When flying enclosures from ceiling support structures, extreme care should be taken to assure the load bearing capabilities of the structures so that the installation is absolutely safe. Do not fly enclosures from unsafe structures. Consult a certified professional if needed. All flying accessories that are not supplied by D.A.S. Audio are the user’s responsibility. Use at your own risk.

Introduction
Flyable vantec series models feature 6 internal steel angles, with 2 mounting threads each, so that 12 flying points are available (2 on each side, 3 on the top panel and 3 on the bottom panel and 2 on the rear panel). Eyebolt flying points are factory sealed with M10 screws, which are replaced with eyebolts on the flying points as required. Flying with eyebolts is very economical and safe, and is specially recommended for fixed installations where the boxes are permanently fixed.
The illustration shows the internal metal hardware of an enclosure with eyebolt flying.

Flying with eyebolts
The Allen-head screws must be removed and replaced by M10 eyebolts on one side of the enclosure. Each rigging point has 200 kg (440 lb) working load limit. Then choose the slings or chains of required load resistance and length, bearing in mind that the length difference between the front and back slings or chains will determine the vertical orientation. Alternatively, the back bottom eyebolt points can be used to provide vertical orientation.
The ANL-2 set is an optional set of four eyebolts and four carabiners. (Dimensions are in millimetres).

• Each ANL-2 eyebolt has a rated working load of 200 kg. (440 lb). Each ANL-2 carabiner has a working load of 330 kg (726 |b). If using other hardware, make sure it is rated to handle the required load.
• When using eyebolts it is important to bear in mind that the rated working load is only true for a load applied in the plane of the eye, and is significantly reduced for other angles. The drawing illustrates the concept. The table shows the variation of the working load as a function of the load angle. In the case of the ANL-2 eyebolt, this means that the 200 kg working load becomes 60 kg at 45 degrees. Do not use eyebolt flying if the load angle is higher than 45 degrees.

The following illustrations show different views on eyebolt flying for a single box. The length of the back cables or chains determines the vertical angle of the box.

APPENDIX

• Line connections: unbalanced and balanced There are two basic ways to transport an audio signal with microphone or line level
• Unbalanced line: Utilizing a two conductor cable, it transports the signal as the voltage between them. Electromagnetic interference can get added to the signal as undesired noise. Connectors that carry unbalanced signals have two pins, such as RCA (Phono) and ¼” (6.35mm, often referred to as jack) mono. 3 pin connector such as XLR (Cannon) may also carry unbalanced signals if one of the pins is unused.
• Balanced line: Utilizing a three conductor cable, one of them acts as a shield against electromagnetic noise and is the ground conductor. The other two have the same voltage with respect to the ground conductor but with opposite signs. The noise that cannot be rejected by the shield affects both signal conductors in the same way. At the device’s input the two signals get summed with opposite sign, so that noise is cancelled out while the programme signal doubles in level. Most professional audio devices use balanced inputs and outputs. Connectors that can carry balanced signal have three pins, such as XLR (Cannon) and ¼” (6.35mm) stereo.
• The graphs that follow show the recommended connection with different types of connectors to balanced processor or amplifier inputs. The connectors on the left-hand side come from a signal source, and the ones on the right hand side go to the inputs of the processor or amplifier. Note that on the unbalanced connectors on the left-hand side, two terminals are joined inside the connector. If hum occurs with balanced to balanced connections, try disconnecting the sleeve (ground) on the input connector. Note that the illustrations show what should be connected to what, but that pin locations on an actual XLR connector are different. Also, pin 2 hot is assumed on XLR connectors.
