Page 8: Safety Notes
Safety notes Safety notes Intended use This device amplifies electric audio frequency signals to operate passive speakers. Use the device only as described in this user manual. Any other use or use under other operating con‐ ditions 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. - Page 9 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.
- Page 10 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.
- Page 11 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.
- Page 12 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 pre- amplifiers, radio transmission systems, or tape decks directly above or below the power amplifier.

Page 14: Installation And Operation
Installation and operation Installation and operation 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. - Page 15 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 pre- amplifiers, radio transmission systems, or tape decks directly above or below the power amplifier.
- Page 16 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.
- Page 17 For detailed information related to this topic please refer to our Online Guide ‘PA Speakers’ (www.thomann.de). Rack mounting The device has been designed for rack mounting in a standard 19-inch rack; it occupies two rack units.
