Safety instructions

Intended use

This device is designed for sound reinforcement. Use the device only as described in this user manual. Any other use or use under other operating conditions is considered to be improper and may result in personal injury or property damage. No liability will be assumed for damages resulting from improper use.This device may be used only by persons with sufficient physical, sensorial, and intellectual abilities and having corresponding knowledge and experience. Other persons may use this device only if they are supervised or instructed by a person who is responsible for their safety

Safety

DANGER!Danger for childrenEnsure that plastic bags, packaging, etc. are disposed of properly and are not within reach of babies and young children. Choking hazard! Ensure that children do not detach any small parts (e.g. knobs or the like) from the unit. They could swallow the pieces and choke! Never let children unattended use electrical devices

CAUTION!Possible hearing damageThe device can produce volume levels that may cause temporary or permanent hearing impairment. Over an extended period of time, even levels that seem to be uncritical can cause hearing damage. Decrease the volume level immediately if you experience ringing in your ears or hearing impairment. If this is not possible, keep a greater distance or use sufficient ear protectors.

CAUTION!Risk of injury due to heavy weightDue to the heavy weight of the device, at least two persons are required for transport and installation

NOTICE!Operating conditionsThis device has been designed for indoor use only. To prevent damage, never expose the device to any liquid or moisture. Avoid direct sunlight, heavy dirt, and strong vibrations. Only operate the device within the ambient conditions specified in the chapter ‘Technical specifications’ of this user manual. Avoid heavy temperature fluctuations and do not switch the device on immediately after it was exposed to temperature fluctuations (for example after transport at low outside temperatures). Dust and dirt inside can damage the unit. When operated in harmful ambient conditions (dust, smoke, nicotine, fog, etc.), the unit should be maintained by qualified service personnel at regular intervals to prevent overheating and other malfunction

NOTICE!Possible stainingThe plasticiser contained in the rubber feet of this product may possibly react with the coating of your parquet, linoleum, laminate or PVC floor and after some time cause permanent dark stains. In case of doubt, do not put the rubber feet directly on the floor, but use felt-pad floor protectors or a carpet.

Installation

Unpack and check carefully there is no transportation damage before using the unit. Keep the equipment packaging. To fully protect the product against vibration, dust and moisture during transportation or storage use the original packaging or your own packaging material suitable for transport or storage, respectively.Create all connections while the device is off. Use the shortest possible high-quality cables for all connections. Take care when running the cables to prevent tripping hazards.

WARNING!Risk of injury caused by falling objectsMake sure that the installation complies with the standards and rules that apply in your country. Always secure the device with a secondary safety attachment, such as a safety cable or a safety chain

CAUTION!Risk of injury due to heavy weightDue to the heavy weight of the device, at least two persons are required for transport and installation.

NOTICE!Possible property damage by magnetic fieldsLoudspeakers produce a static magnetic field. Therefore, maintain an appropriate distance to devices that can be adversely affected or damaged by an external magnetic field.

Tips on handling speakersWe recommend you to set up the speakers in a way, that the sound signals can reach the audience unobstructed. It will often be helpful to mount the speakers on tripods. Thus, the sound will be evenly spread with maximum range throughout the audience area.Always use high grade cable to connect your equipment. Otherwise you won’t reach maximum sound quality.For optimum results both impedance and power handling of the speakers must match the requirements of the amplifier. Always follow the technical specifications of the speakers! The overall impedance of the connected loudspeakers must not deceed the minimum output impedance of the amp. The amps max. RMS output power should be 50 % above the power handling capacity of the connected speakers.If you notice distortion during operation, either the amp or the speaker is overloaded. This may permanently damage the amp or the speaker. Always reduce the volume when you hear distortion.

Terminals for wiring ‘Bass to 1’

In order to use the terminals for wiring ‘Bass to 1’, turn the cover of the connector panel so that the notches are in horizontal position1, 2 NL4 terminals, wired in parallel (1+/1– to bass; 2+/ 2– looped-through) With this wiring option, you can connect the bass directly using a two-wire cable (wires 1+/1–).If you are using four-wire cables, you can use heads that receive their signal via wires 2+/ 2 and loop wires 1+/ 1– through. The bass is connected to wires 1+/1– and loops wires 2+/ 2 through. The order in which the speakers are wired doesn’t matter. Never fall below the minimum load impedance, though.

NL4 mounting connectors for speaker connectionsThe adjoining figure shows the pin assignment of the lockable NL4 panel connectors.

Connecting to the Achat systemIn order to use the terminals for the Achat system wiring, turn the cover of the connector panel so that the notches are in vertical position.3, 4 NL4 terminals, wired in parallel (2+/ 2– to bass; 1+/1– looped-through)

These terminals allow for easy wiring with four-wire cables, as the heads get their signal via wires 1+/ 1– and loop wires 2+/ 2– through; the bass is connected to wires 2+/2– and loops wires 1+/ 1– through. The order in which the speakers are wired doesn’t matter. Never fall below the minimum load impedance, though.
