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.
