Page 7: Safety Instructions
Safety instructions Safety instructions 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. - Page 8 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.
- Page 9 Safety instructions 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.
- Page 10 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.
- Page 11 Safety instructions 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 pre- amplifiers, radio transmission systems, or tape decks directly above or below the power amplifier.

When switching on the protection circuits are activated. After a few seconds you will hear two "clicks" - now the speakers are electrically connected to the amplifier and the device is ready to operate.

Page 20: Installation And Starting Up
Installation and starting up Installation and starting up Unpack and check carefully there is no transportation damage before using the unit. Establish all connections as long as the unit is switched off. Use the shortest possible high- quality cables for all connections. DANGER! Electric shock caused by high voltages at the power amplifier output The output voltages of modern high-performance amplifiers may result in death... - Page 21 Installation and starting up 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 pre- amplifiers, radio transmission systems, or tape decks directly above or below the power amplifier.

Page 26: Tips On Handling Speakers
Installation and starting up 4.2 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. -
Page 27: More Useful Tips
Installation and starting up 4.3 More useful tips 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 (CH1 and CH2) is amplified and connected to loudspeakers, the volume can be controlled separately for the two outputs. - Page 28 Example: If you have two loudspeakers with the same impedance, their impedance doubles if they are connected in a series, their impedance halves if they are connected in parallel.
