Warranty

Active Audio guarantees, that every new product purchased at an authorized distributor is free of assembly and material defects. During the guarantee, the purchaser is entitled to repairs free of charge in cases ivolving assembly defects.
Defects reported during the time of the guarantee will be repaired by an authorized dealer free of charge within 21 days from the date that the equipment is delivered for repair – the time of repair may be extented if the job requires parts to be acquired from another country.
The guarantee is extended by the time it takes to complete reparations of the product.
Under the guarantee, those repairs for which instructions are given in the manual will not be cover, and are the sole responsiblity of the owner’s time and cost. For example, the installation of equipment, the testing, maintenance (especially the cleaning of the filter), and interchanging the fuses. All of the afore mentioned repairs can be made by the dealer at the customer’s own cost.

Guarantee does not cover:

  • Mechanical, chemical, and thermal damages inflicted on the equipment.
  • Damages and defects caused by wrongful installation, usage, storage, and maintenance.
  • Damages caused by repairs and changes to the equipment made by the customer or other unauthorized persons.
    The owner provides damaged equipment for repairs or sale at his or her time and cost, preferably in the original package. If the original package is missing, the risk of  product damage is higher and the owner assumes all financial losses.

Safety tips

2.1. Equipment Setup
Avoid setting up the equipment areas:

  • subject to direct sunlight
  • exposed to high temperatures
  • exposed to moisture
  • subject to high vibrations
  • on an uneven surface
    Non compliance can lead to damaging the outside frame and/ or other parts – which could shorten the allotted time of operation.

2.2. Ventilation
Install the equipment in the area with proper ventilation – with a distance of at least 10cm from the rear of the device to the wall. Remember that objects such as curtains  should not cover the ventilation openings.

PLACING OBJECTS ON TOP OF THE AMPLIFIER
Do not place heavy object on top of the amplifier or on the electrical cord.
Such actions could cause the top plate to be permanently deformed or the electrical cord to be severed.

2.3. Voltage
The equipment cannot be plugged into a DC socket. Make sure the parameters of the socket are known.

2.4. Electrical cord
When inserting the electrical cord into the socket, hold the plug firmly and make sure it is propely placed into the socket. Never attempt to touch the socket with moist hands.
Avoid cutting, scratching, over bending, stretching, and folding the electrical cord. Such actions could cause a fire or electrical shock.
When unplugging the cord do not pull the wire because an electrical shock could result.

2.5. Foreign objects

  • Do not allow objects such as needles, coins, screws, etc to accidentally fall into the equipment through the ventilation openings. The result could be serious damage to  the amplifier and electrical shock.
  • At no time should water or any other liquid to be spilled on or into the equipment due to the high risk of fire or shock.
  • Avoid using any aerosol sprays around the equipment.

2.6. Service
Never try to take apart, fix or repair the equipment. If problems arise at time of operation (interrupted sound, signals do not light up, traces of smoke arise, etc.) Immediately  turn off the amplifier and contact an authorized dealer. If the equipment will not be used for an extented period of time , unplugged the amplifier from the outlet.
2.7. Maintenance
Clean the frame, the main frame, and the regulator witch a soft moist towel, lightly covered with a gentle detergent. Do not use any abrasive materials or detergents.
Do not use any solvent such as alcohol or gasoline.

Troubleshooting

Symptom Possible causes Solution
No output and on or several CLIP leds lit Input levels too high Decrease

output level from  source upstream the amplifier
No output and CLIP leds not lit| Bad selection of input source or bad setting of Volume control| Check dip switchs of source  selection and set-ting of Volume  control
Clic’ noise of relay and CLIP leds lit| Output shorted| Check cabling of inputs and outputs
Low level on loudspeaker babied in bridge mode.| Wrong selection of mode with switch| Check mode selection switch, which must be on Bridge
