General information 1.2 Notational conventions This manual uses the following notational conventions: Letterings The letterings for connectors and controls are marked by square brackets and italics. Examples: [VOLUME] control, [Mono] button. 1.3 Symbols and signal words In this section you will find an overview of the meaning of symbols and signal words that are used in this manual.
General information Signal word Meaning DANGER! This combination of symbol and signal word indicates an immediate dangerous situation that will result in death or serious injury if it is not avoided. CAUTION! This combination of symbol and signal word indicates a pos‐ sible dangerous situation that can result in minor injury if it is not avoided.
Safety instructions 2 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.
Safety instructions DANGER! Electric shock caused by high voltages inside Within the device there are areas where high voltages may be present. Never remove any covers. There are no user-serviceable parts inside. Do not use the device if covers, protectors or optical components are missing or damaged. DANGER! Electric shock caused by short-circuit Always use proper ready-made insulated mains cabling (power cord). Do not modify the mains cable. Failure to do so could result in electric shock/death or fire.
Safety instructions CAUTION! Possible hearing damage The 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 suffi‐ cient ear protectors. NOTICE! Risk of fire Do not block areas of ventilation.
Safety instructions NOTICE! Operating conditions This 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. NOTICE! Power supply Before connecting the device, ensure that the input voltage (AC outlet) matches the voltage rating of the device and that the AC outlet is protected by a residual current circuit breaker.
Safety instructions NOTICE! Possible damage due to installation of a wrong fuse The use of different types of fuses can cause serious damage to the unit. Fire hazard! Only fuses of the same type may be used.

Installation 4 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.
Installation NOTICE! Possible property damage by magnetic fields Loudspeakers produce a static magnetic field. Therefore, maintain an appropriate distance to devices that can be adversely affected or damaged by an external magnetic field. 4.1 Tips on handling speakers We recommend you to set up the speakers in a way, that the sound signals can reach the audi‐ ence unobstructedly. It will often be helpful to mount the speakers on tripods.
Connections and controls 5 Connections and controls active speaker 16
Connections and controls 1 [Balanced Outputs] Balanced line signal outputs, designed as XLR chassis plug. 2 [Balanced Inputs] Balanced line signal inputs, designed as XLR chassis socket. 3 [Phase] If necessary, this switch shifts the phase of the subwoofer signal by 180 °. This avoids unwanted cancellation effects in combination with other speakers. 4 [Subwoofer Level] Volume control. 5 [Xover] Crossover frequency switch Toggles between 90 Hz and 120 Hz.
Connections and controls 7 [Signal] LED (green): Indicates that the input signal is present. 8 [Limit] LED (red): Indicates overload. In this case, the level of the line input signal is too high. 9 [Power] LED (blue): Indicates that operating voltage is present. 10 [POWER] Mains switch. Turns the device on and off. 11 IEC chassis plug with fuse for the power supply.

Plug and connection assignment 7 Plug and connection assignment Introduction This chapter will help you select the right cables and plugs to connect your valuable equip‐ ment in such a way that a perfect sound experience is ensured.
Plug and connection assignment Since the interference affects both cores equally, by subtracting the phase-shifted signals, the interfering signal is completely neutralized. The result is a pure signal without any noise inter‐ ference.
