• We also recommend you keep this instruction manual handy for future reference.

Safety Symbol and Message
Conventions. Safety symbols and messages described below are used in this manual to prevent bodily injury and property damage, which could result from mishandling. Before operating your product, read this manual first and understand the safety symbols and messages so you are thoroughly aware of the potential safety risk.

When Installing the Unit.

• Do not expose the unit to rain or an environment where it may be splashed by water or other liquids, as doing so may result in fire or electric shock.
• Use the unit only with the voltage specified on the unit. Using a voltage higher than that which is specified may result in fire or electric shock.
• Do not cut, kink, or otherwise damage nor modify the power supply cord. In addition, avoid using the power cord close to heaters, and never place heavy objects — including the unit itself — on the power cord, as doing so may result in fire or electric shock.
• Be sure to replace the unit’s terminal cover after connection completion. Because high voltage is applied to the speaker terminals, never touch these terminals to avoid electric shock.
• Be sure to ground to the safety ground (earth) terminal to avoid electric shock. Never ground to a gas pipe as a catastrophic disaster may result.
• Avoid installing or mounting the unit in unstable locations, such as on a rickety table or a slanted surface. Doing so may result in the unit falling, causing personal injury and/or property damage.

When the unit is in use.

• Should the following irregularity be found during use, immediately switch off the power, disconnect the power supply plug from the AC outlet, and contact your nearest ArtSound dealer. Make no further attempt to operate the unit in this condition as this may cause fire or electric shock.
• If you detect smoke or a strange smell coming from the unit.
• If water or any metallic object gets into the unit
• If the unit falls, or the unit case breaks
• If the power supply cord is damaged (exposure of the core, disconnection, etc. )
• If it is malfunctioning (no tone sounds.)
• To prevent a fire or electric shock, never open nor remove the unit case as there are high-voltage components inside the unit. Refer all servicing to your nearest ArtSound dealer.
• Do not place cups, bowls, or other containers of liquid or metallic objects on top of the unit. If they accidentally spill into the unit, this may cause a fire or electric shock.
• Do not insert nor drop metallic objects or flammable materials in the ventilation slots of the unit’s cover, as this may result in fire or electric shock.

Features

• With 1U chassis design, an internal combination of switching power supply and digital power amplifier higher efficiency, lightweight, and delicate appearance.
• MP3 decoding module supports automatic switching of USB/SD/Bluetooth/FM playback, configures MP3 remote control; supports power-off memory function, MIC recording function.
• Support 1 channel EMC input, 2 channels AUX input, and 4 channels MIC input.
• Each input has independent volume adjustment with treble, bass, and volume control.
• The equipment is equipped with level indication, overload, and protection indicators, and has good protection for short circuits, overload, and overheating situations.
• With the mute function, microphone input, the microphone is before line input; mute function, MIC1 is before other audio inputs, and EMC takes precedence over all audio inputs.
• Channel priority function: EMC>MIC1>MIC2/MIC3/ MIC4/AUX1/AUX2/MP3.
• Adopt an advanced and high-efficiency power amplify circuit, the speaker output is 100V or 4 ohms; the rated output power is 120W.
• Input AC power, power supply 180W.
• It is forced to air-cool from the front to the rear, and it rotates at a constant speed when starting up. It speeds up as the temperature rises and can work for a long time.
