General notes 1 General notes This user manual contains important information on the safe operation of the device. Read and follow all safety notes and all instructions. Save this manual for future reference. Make sure that it is available to all persons using this device. If you sell the device to another user, be sure that they also receive this manual. Our products are subject to a process of continuous development. We therefore reserve the right to make changes without notice.
General notes 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 possible dangerous situation that can result in minor injury if it is not avoided.
General notes Warning signs Type of danger Warning – danger zone.
Safety notes 2 Safety notes Intended use Use the device only as described in this user manual. Any other use or use under other oper‐ ating 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.
Safety notes 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 notes CAUTION! Possible hearing damage With loudspeakers or headphones connected, the device can produce volume levels that may cause temporary or permanent hearing impairment. Do not operate the device permanently at a high volume level. Decrease the volume level immediately if you experience ringing in your ears or hearing impairment. 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.
Safety notes 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 notes NOTICE! Magnetic fields The device generates strong magnetic fields that can interfere with the function of poorly shielded devices. The strongest magnetic fields are directly above and below the power amplifier. Therefore, never place sensitive devices such as preamplifiers, radio transmission systems, or tape decks directly above or below the power amplifier.
Installation and operation 3 Installation and operation Unpack and check carefully 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 and operation NOTICE! Magnetic fields The device generates strong magnetic fields that can interfere with the function of poorly shielded devices. The strongest magnetic fields are directly above and below the power amplifier. Therefore, never place sensitive devices such as preamplifiers, radio transmission systems, or tape decks directly above or below the power amplifier.
Installation and operation XLR connectors for signal inputs and outputs Jack plug for signal inputs and outputs Balanced female XLR panel connectors are used for the signal inputs. Male XLR panel connec‐ tors are used for the signal outputs The figure and the table show the XLR pin assignment. 1 Ground 2 Signal (+) 3 Signal (–) The figure and the table show the pin assignment of the ¼-inch (6.35-mm) jack plugs (unbal‐ anced and balanced).
Installation and operation speakON connector for loud‐ speaker connections 1 Signal 2 Ground 1 Signal (+) 2 Signal (–) 3 Ground The following figure shows the pin assignment of the lockable speakON panel connector.

Installation and operation Possible operation modes Depending on the individual application, the amplifier can be used in different operation modes: Stereo mode The two amplifier channels operate independently of one another, either channel (A and B) is amplified and connected to loudspeakers, the volume can be controlled separately for the two outputs.
Installation and operation For each output of the amplifier, the total impedance resulting from the loudspeakers con‐ nected to it must not be below the allowed minimal impedance of the amplifier output. If you connect more than one loudspeaker to an amplifier output, please note the following: n If the loudspeakers are connected in a series, the individual impedances will be added up.

Connectors and controls 1 POWER Power on/off switch. Switches the device on and off. 2 LED panel SIG Indicates the presence of an input signal. CLIP Lights under the following conditions: n Channel overdrive. In this case, reduce the volume until the LED turns off. n Short-circuit at the output. Immediately turn off the device, fix the short-circuit and turn on the device again.
Connectors and controls POWER This LED shows that the device is turned on. PAR Lights when the device is operated in parallel mode. BRI Lights when the device is operated in bridged mode. 3, 4 CHANNEL A, CHANNEL B Volume control for the respective channels.

Connectors and controls 8 Ground/Lift switch If there are hums due to a ground loop, you can use this switch to disconnect the protective earth connector from the signal ground of the device. 9 LIMITER Limits the output level such that maximum distortion is 5 %.
Connectors and controls 13, 14 INPUT Input channel B, A n Female XLR panel connector n ¼-inch (6.35-mm) jack (balanced or unbalanced) 15 BREAKER Resettable fuse. The fuse disconnects the amplifier when the power consumption is too high, for example due to a short-circuit. As soon as the problem is solved, the fuse will automatically be reset, the device will work again. Using the switch, the reset can be enforced.
