3 USER RESPONSIBILITY

3.1 Speaker damage

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 gain is

reduced by using the amplifier's front panel attenuator, it is still possible to

reach full output power, if the input signal level is high enough.

3.2 Shock hazard

Power amplifiers are capable of producing hazardous output voltages.

To avoid electrical shock, do not touch any exposed speaker wiring when

the amplifier is operational. See page 11 regarding correct connection of

outputs to loudspeakers.

3.3 Radio interference

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. Compliance with the (EMC) directive does not

automatically guarantee non-disturbance of susceptible equipment in close

proximity to this amplifier.

If the amplifier is suspected of causing interference, this can be easily checked

by powering the unit on and off and observing the disturbance.

The user can correct the interference by one or more of the following steps:

1. Increase the distance between the equipment.

2. Connect the power cable to a socket on a different circuit from

that to which the affected unit is connected.

3. If a radio receiver is affected (normally only am receivers are

affected); re-orientate the antenna.

4. Check if the affected equipment 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.
