Important Precautions
This symbol is used to alert the oper- ator to follow important operating procedures and precautions detailed in documentation.
This symbol is used to warn opera- tors that uninsulated “dangerous volt- ages” are present within the equip- ment enclosure that may pose a risk of electric shock.
1.Save the carton and packing material even if the equipment has arrived in good condition. Should you ever need to ship the unit, use only the original factory packing.
2.Read all documentation before oper- ating your equipment. Retain all doc- umentation for future reference.
3.Follow all instructions printed on unit chassis for proper operation.
4.Do not spill water or other liquids into or on the unit, or operate the unit while standing in liquid.
5.Make sure power outlets conform to the power requirements listed on the back of the unit.
6.Do not use the unit if the electrical power cord is frayed or broken. The power supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon or against them, paying particular atten- tion to cords and plugs, convenience receptacles, and the point where they exit from the appliance.
7.Always operate the unit with the AC ground wire connected to the electri- cal system ground. Precautions should be taken so that the means of ground- ing of a piece of equipment is not defeated.
8.Mains voltage must be correct and the same as that printed on the rear of the unit. Damage caused by connec- tion to improper AC voltage is not cov- ered by any warranty.
9.Have gain controls on amplifiers turned down during
10.Power down & disconnect units from mains voltage before making connec- tions.
11.Never hold a power switch in the “ON” position if it won’t stay there itself!
12.Do not use the unit near stoves, heat registers, radiators, or other heat producing devices.
13.Do not block fan intake or exhaust ports. Do not operate equipment on a surface or in an environment which may impede the normal flow of air around the unit, such as a bed, rug, weathersheet, carpet, or completely enclosed rack. If the unit is used in an extremely dusty or smoky environ- ment, the unit should be periodically “blown free” of foreign matter.
14.Do not remove the cover. Removing the cover will expose you to potentially dangerous voltages. There are no user serviceable parts inside.
15.Connecting amplifier outputs to oscilloscopes or other test equipment while the amplifier is in bridged mode may damage both the amplifier and test equipment!
16.Do not drive the inputs with a signal level greater than that required to drive equipment to full output.
17.Do not connect the inputs / outputs of amplifiers or consoles to any other voltage source, such as a battery, mains source, or power supply, regard- less of whether the amplifier or console is turned on or off.
18.Do not run the output of any amplifi- er channel back into another chan- nel’s input. Do not parallel- or
19.Do not ground any red (“hot”) ter- minal. Never connect a “hot” (red) output to ground or to another “hot” (red) output!

21. Service Information E q u i p m e n t should be serviced by qualified service personnel when:
A.The power supply cord or the plug has been damaged;
B.Objects have fallen, or liquid has been spilled into the equipment;
C.The equipment has been exposed to rain;
D. The equipment does not appear to operate normally, or exhibits a marked change in performance;
E.The equipment has been dropped, or the enclosure damaged.
