Safety instructions 2 Safety instructions Intended use This device is intended to be used in a sound reinforcement system. This device is designed for professional and not household use. 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 Safety DANGER! Danger for children Ensure 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. DANGER! Electric shock caused by high voltages inside Within the device there are areas where high voltages may be present.
Safety instructions DANGER! Electric shock caused by short-circuit Always use proper ready-made insulated mains cabling (power cord) with a pro‐ tective contact plug. Do not modify the mains cable or the plug. Failure to do so could result in electric shock/death or fire. If in doubt, seek advice from a regis‐ tered electrician. CAUTION! Possible hearing damage The device can produce volume levels that may cause temporary or permanent hearing impairment.
Safety instructions CAUTION! Risk of injury due to heavy weight Due to the heavy weight of the device, at least two persons are required for trans‐ port and installation. NOTICE! Risk of fire Do not block areas of ventilation. Do not install the device near any direct heat source. Keep the device away from naked flames. NOTICE! Operating conditions This device has been designed for indoor use only. To prevent damage, never expose the device to any liquid or moisture.
Safety instructions 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. Failure to do so could result in damage to the device and possibly injure the user. Unplug the device before electrical storms occur and when it is unused for long periods of time to reduce the risk of electric shock or fire.

Installation 4 Installation Unpack and carefully check that there is no transportation damage before using the unit. Keep the equipment packaging. To fully protect the device 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. NOTICE! Use of stands When mounting the device onto a stand, ensure that the stand is in a safe and stable position and that the weight of the device does not exceed the maximum permissible load capacity of the stand.
Installation 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. 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 max‐ imum sound quality.
Connections and operating elements 5 Connections and operating elements active 2-way-full-range-speaker 18
Connections and operating elements 1 [VOLUME] Volume control. Turn the knob clockwise to increase the volume or counterclockwise to decrease the volume. 2 [BASS] Bass control. Turn the knob clockwise for a more bassy sound. Turn the knob counterclockwise to decrease the bass. 3 [TREBLE] Treble control. Turn the knob clockwise for a brighter sound. Turn the knob counterclockwise to decrease the treble. 4 [INPUT] Signal input with switchable sensitivity, designed as XLR chassis socket.
Connections and operating elements 7 IEC chassis plug with fuse holder for the power supply. Defective fuses must always be replaced by fuses of the same type. 8 [115V/60Hz — 230V/50Hz] Selector switch for the power supply. Make sure that, before activating the device, the switch position is set to the local supply voltage. 9 [LINE/MIC] Push-button to select the input sensitivity of the speaker (line or microphone level). Push the push-button with a suitable sharp tool, e.g. a ballpen.
Connections and operating elements 12 [120Hz] Low cut switch to lower frequencies below 120Hz. This function reduces impact noise and maximize the lifetime of the woofer. 13 [CLIP] Indicates overload. If the LED flickers or is lit, the input signal level is too high.

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.
Protecting the environment 8 Protecting the environment Disposal of the packaging mate‐ rial For the transport and protective packaging, environmentally friendly materials have been chosen that can be supplied to normal recycling. Ensure that plastic bags, packaging, etc. are properly disposed of. Do not just dispose of these materials with your normal household waste, but make sure that they are collected for recycling.
