Any other use or use under other operating 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. Other persons may use this device only if they are supervised or instructed by a person who is responsible for their safety.

Safety

Children can suffocate on packaging material and small parts. Children can injure themselves when handling the device. Never allow children to play with the packaging material and the device. Always store packaging material out of the reach of babies and small children. Always dispose of packaging material properly when it is not in use. Never allow children to use the device without supervi‐sion. Keep small parts away from children and make sure that the device does not shed any small parts (such knobs) that children could play with.

WARNING!

• Possible hearing damage due to high volumes on speakers or headphones!
• With speakers or headphones connected, 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.
• 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!

• Damage to the device if operated in unsuitable ambient conditions!
• The device can be damaged if it is operated in unsuitable ambient conditions.
• Only operate the device indoors within the ambient conditions specified in the “Technical specifications” chapter of this user manual.
• Avoid operating it in environments with direct sun‐light, heavy dirt and strong vibrations.
• Avoid operating it in environments with strong temperature fluctuations.
  If temperature fluctuations cannot be avoided (for example after transport in low outside temperatures), do not switch on the device immediately.
• Never subject the device to liquids or moisture.
• Never move the device to another location while it is in operation.
• In environments with increased dirt levels (for example due to dust, smoke, nicotine or mist)
• Have the device cleaned by qualified specialists at reg‐ular intervals to prevent damage due to overheating and other malfunctions.

NOTICE!

• Danger of short circuit due to use of unbalanced XLR cables!
• The device has a phantom voltage input. Using unbalanced cables with the phantom power may damage the device.
• Use only bal‐anced cables. Before switching on phantom power, always make sure that no unbalanced wired cables are connected.

Installation and starting up

• Unpack and check carefully there is no transportation damage before using the unit.
• Keep the equipment packaging.
• To fully protect the product 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.
• Take care when running the cables to prevent tripping hazards.

Connections and controls

• [USB TO COMPUTER] | USB port for connecting to a computer for use as an audio interface and for power supply.
• [MIC TO CH 1] | For connecting the microphone if a headset is in use, signal processing via channel 1.
• [MONITOR – HEADSET] | For connecting the headphones if a headset is in use.
• [POWER] | The LED lights up when the device is powered.
• [PHANTOM] | Turns the phantom power on and off for condenser microphones on the XLR inputs. The LED above the
  switch is on if phantom power is activated.
• [USB Playback] | When the switch is pressed, the USB input signal is assigned to the ‘Monitor’ output, otherwise to the
  ‘MAIN MIX’ output.
• [MONITOR] | Volume control for the monitor output.
• [L – CLIP – R] | The ‘L’ or ‘R’ LED lights up green when a signal is present on the respective bus side. It lights up red when an
  overload occurs on the respective bus side. In this case, lower the input levels that could be causing the overload or turn
  the ‘MAIN MIX’ control anti-clockwise.
• [PEAK] | This LED lights up in case of an overload in channel 2. In this case, switch the [GAIN] switch to the LOW position.
• [MAIN MIX] | Volume control for the ‘MAIN MIX’ output and the USB port.
• [CH 2] | Level control for the signals on input ‘CH2’ .
• [CH1] | Level control for the signals on input ‘CH1’ .
• [PEAK] | This LED lights up in case of an overload in channel 1. In this case, turn the [GAIN] control anti-clockwise until the
  LED goes out.

Plug and connection assignment
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. Please note these advices, because especially in ‘Sound & Light’ caution is indicated: Even if a plug fits into the socket, an incorrect connection may result in a destroyed power amp, a short circuit or ‘just’ in poor transmission quality!

Balanced and unbalanced transmission

• Unbalanced transmission is mainly used in semi-professional environment and in hifiuse. Instrument cables with two conductors (one core plus shielding) are typical representatives of the unbalanced transmission. One conductor is ground and shielding while the signal is trans‐ mitted through the core.
• Unbalanced transmission is susceptible to electromagnetic interference, especially at low levels, such as microphone signals and when using long cables.
• In a professional environment, therefore, the balanced transmission is preferred, because this enables an undisturbed transmission of signals over long distances. In addition to the conductors ‘Ground’ and ‘Signal’, in a balanced transmission a second core is added. This also transfers the signal, but phase-shifted by 180°.
• 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 interference.

Protecting the environment

Disposal of the packing material

• Environmentally friendly materials have been chosen for the packaging.
• These materials can be sent for normal recycling. Ensure that plastic bags, packaging, etc. are disposed of in the proper manner.
• Do not dispose of these materials with your normal household waste, but make sure that they are collected for recycling. Please follow the instructions and markings on the packaging.
