General notes Symbols and signal words This section provides an overview of the symbols and signal words used in this user manual. 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.
General notes Warning signs Type of danger Warning – danger zone.
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. 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.
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 cover the device nor any ventilation slots.
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.
Features 3 Features The active monitors are suitable for amateur use in smaller rooms as well as professional use on very large stages. Special features of the device: n 2-way system: 1" tweeter and 10", (item no. 309203), 12", (item no. 309205) or 15" woofer (item no.
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. Establish all connections as long as the unit is switched off. Use the shortest possible highquality cables for all connections.
Installation 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.
Connections and operating elements 5 Connections and operating elements Rear panel active monitor 14
Connections and operating elements 1 XLR chassis plug LINK This outlet can be used to feed the signal to further active speakers. 2 XLR / phone combo socket LINE IN Line level input for balanced or unbalanced signals. 3 Ground/Lift button If a ground loop is causing hum you can use this switch to cut the connection between the earth pin of the device and the signal ground in the device. 4 IEC chassis connector for operating voltage supply. 5 Fuse holder.
Connections and operating elements 7 Mains switch POWER Turns the unit on or off. 8 MONITOR/FOH button Use this switch to select various EQ characteristics, suitable for different applications. MONITOR: For use as stage monitor with feedback suppression FOH: For use as PA speaker (front of house) 9 LED ON This LED lights up green when the device is switched on and voltage supply is present.
Connections and operating elements 10 LED SIGN/LIMIT This LED lights up green on incoming input signal. This LED lights up red when the internal output signal is being limited (excessive input signal!). 11 Rotary control LEVEL Control to adjust the LINE input level. Turn the knob clockwise or counter-clockwise to increase or decrease the input volume. In zero-position, the signal is completely attenuated. In maximum position, the signal is processed without any attenuation.

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.

Troubleshooting 8 Troubleshooting In the following we list a few common problems that may occur during operation. We give you some suggestions for easy troubleshooting: Symptom Remedy The unit does not work 1. Check the power supply connection and the position of the mains switch POWER. No sound 1. Check the position of the rotary control LEVEL. 2. Check whether the LED SIGN/LIMIT lights up green. If it doesn't, the input signal is too weak 3. Check for correct signal cable connection. 4.
Troubleshooting Symptom Remedy Audible distortion Excessive input signal. Reduce the signal level. Never operate the loudspeaker with such a high signal level that the SIGN/LIMIT LED lights solid red! Different channel levels (when using two monitors) 1. Make sure that for both channels the same type of cable (balanced, unbalanced) is used. 2. Make sure that your speaker system is fully connected and both speakers have the same input impedance.
