Safety instructions 2 Safety instructions Intended use This device is intended to be used in a sound reinforcement system. Use the device only as described in this user manual. Any other use or use under other operating conditions is consid‐ ered 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) with a pro‐ tective contact plug. Do not modify the mains cable or the plug.
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.

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 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. If you notice distortion during operation, the active speaker is overloaded.
Connections and operating elements 5 Connections and operating elements PA 108 A 15
Connections and operating elements 1 [VOLUME] Volume control. Turn the knob clockwise to increase the volume or counterclockwise to decrease the volume. 2 [TREBLE] Treble control. Turn the knob clockwise for a brighter sound. Turn the knob counterclockwise to decrease the treble. 3 [BASS] Bass control. Turn the knob clockwise for a more bassy sound. Turn the knob counterclockwise to decrease the bass. 4 [OUTPUT] Line output for connecting further powered speakers, designed as XLR chassis plug.
Connections and operating elements 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 [STANDBY] Pushbutton to enable or disable the power saving mode. If the speaker box is in power save mode and receives no signal for 60 minutes, it switches to standby mode. As soon as the unit receives a signal, it switches automatically back to normal mode. LED [ACTIVE] Power indicator.
Connections and operating elements 10 [LINE/MIC] Button to select the input sensitivity of the speaker (line or microphone level). LED [MIC] The LED lights in operation when the input sensitivity is set to MIC. LED [LINE] The LED lights in operation when the input sensitivity is set to LINE. 11 [120Hz] Low cut switch to lower frequencies below 120 Hz. This function reduces impact noise and maximize the lifetime of the woofer. 12 [CLIP] Indicates overload.

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.
