important precautions
1Save the carton and packing materi- als! Should you ever need to ship the unit, use only the original factory pack- ing.
For replacement packaging, call Crest Audio’s Customer Service Department directly.
2 Read all documentation before operating your equipment. Retain all documentation for future reference.
3Follow all instructions printed on unit chassis for proper operation.
4Never hold a power switch or cir- cuit breaker in the "on" position, if it won’t stay there by itself!
5Do 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.
6Always operate the unit with the AC ground wire connected to the electrical system ground. Precautions should be taken so that the means of grounding of a piece of equipment is not defeated.
7Damage caused by connection to improper AC voltage is not cov- ered by any warranty. Mains voltage must be correct and the same as that printed on the rear of the unit.
8Do not ground any hot (red) terminal.
Never connect a hot (red) output to ground or to another hot (red) output!
9Power down and disconnect units from mains voltage before making connections.
0Do not drive the inputs with a signal level greater than that required to enable equipment to reach full output.
¡Do not run the output of any ampli- fier channel back into another channel’s input.
Do not parallel- or
Crest Audio is not responsible for damage to loudspeakers for any reason.
ÔDo not connect the inputs or outputs of amplifiers to any other voltage source: such as a battery, mains source, or power supply, regard- less of whether the amplifier is turned on or off.
£Connecting amplifier outputs to oscilloscopes or other test equip- ment while the amplifier is in bridged mono mode may damage both the amplifier and test equipment!
¢Do not spill water or other liquids into or on the unit, or operate the unit while standing in liquid.
ˆDo 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 environment: the unit should be periodically blown free of foreign matter.
¶Do not use the unit near stoves, heat registers, radiators, or other heat producing devices.
ƒThe power cord of equipment should be unplugged from the out- let when left unused for a long period of time.
