15.  Do not run the output of any amplifier back into another channel's input. 
16.  Refer all servicing to qualified service personnel. Servicing is required when the apparatus has 

been damaged in any way such as: 

• 

Power-supply cord or plug is damaged 

• 

Liquid has been spilled into the unit 

• 

An object has fallen into the unit 

• 

The unit has been exposed to rain or moisture 

• 

The unit does not operate normally 

• 

The unit was dropped or the enclosure is damaged 

17.  Do not remove top or bottom covers. Removal of the cover will expose hazardous voltages. 

There are no serviceable parts inside and removal may void the warranty. 

18.  An experienced user shall always supervise this professional audio equipment, especially if 

inexperienced adults or minors are using the equipment.

Your amplifier is very powerful and can be potentially dangerous to both, loudspeakers and 
humans alike. Many loudspeakers can be easily damaged or destroyed by overpowering, 
especially with the high power available from a bridged amplifier. Always check the speakers’ 

continuous and peak power capabilities.  
Even if the amplifier’s front panel attenuators can be used to reduce the gain, it is still possible to reach 
full output power if the input signal level is high enough.

Power amplifiers are capable of producing hazardous output voltages. To avoid electrical s
do not touch any exposed speaker wiring while the amplifier is operating. See page

A sample of this product has been tested and complies with the limits for the European Electro 
Magnetic Compatibility (EMC) directive.  These limits are designed to provide reasonable protection 
against harmful interference from electrical equipment. This product uses radio frequency energy and if 
not used or installed in accordance with these operating instructions, may cause interference to other 
equipment, such as radio receivers. However, there is no guarantee that interference will not occur in a 
particular installation. 
If this equipment does cause harmful interference to radio or television reception, which can be 
determined by turning the equipment on and off, the user is encouraged to try to correct the interference 
by one or more of the following measures: 

• 

Reorient or relocate the antenna. 

• 

Increase the separation between the equipment and receiver. 

• 

Connect the equipment into an outlet on a circuit different from that to which the receiver is 
connected. 

• 

Check if the affected unit complies with the EMC limits for immunity, (CE-labelled). If not, 
address the problem with the manufacturer or supplier. All electrical products sold in the 
EC must be approved for immunity against electromagnetic fields, high voltage flashes, and 
radio interference. 

• 

Consult the dealer or an experienced radio/TV technician for help.
