10. Do not use this amplifier if the power cord is broken or frayed. Protect the power cord from
being walked upon or pinched - particularly at the plugs and the point where the power cord
exits from the apparatus.
11. Only use accessories specified by the manufacturer.
12. The unit is intended to be mounted in a 19” rack. Follow the mounting instructions outlined in
this manual and always rear support the unit when used in portable applications. When a rack
on wheels is used for portable applications, use caution when moving the loaded rack in order
to avoid injury from tipping over.
13. Unplug this apparatus during lightning storms or when unused for long periods of time.
14. Do not connect an amplifier output in parallel or series with any other amplifier’s output. Do
not connect the amplifier output to any other voltage source, such as a battery, mains source,
or power supply, regardless of whether the amplifier is turned on or off.
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 the use of professional audio equipment, especially
if inexperienced adults or minors are using the equipment.
2.5 USER RESPONSIBILITY
2.5.1 SPEAKER DAMAGE
Your amplifier is very powerful and can be potentially dangerous to both loudspeakers and
humans alike. Loudspeakers can be damaged or destroyed by overpowering, especially with
the high power available from a bridged amplifier. Always check the loudspeaker’s continuous
and peak power handling capabilities. Note: even when using the amplifier’s front panel attenuator to
reduce the gain, it is still possible to reach full output power if the input signal level is high enough.
2.5.2 SPEAKER OUTPUT HAZARD
Power amplifiers are capable of producing hazardous output voltages. To avoid electrical
shock, do not touch any exposed speaker wiring while the amplifier is operating. Refer to
Section 6.2 concerning proper connection of loudspeakers.
2.5.3 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 such as radio receivers. However, there is no guarantee that interference will not
occur in a particular installation.
