Department directly.

 

 

2

Read all documentation

before

 

operating your equipment. Retain all

 

documentation for future reference.

3

Follow all instructions printed on

 

unit chassis for proper operation.

4

 

 

 

Never hold a power switch or cir-

 

cuit breaker in the "ON" position

 

if it won’t stay there by itself!

5

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.

 

 

6

Always 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.

 

 

 

7

Damage 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.

 

 

8

Do not ground any hot (red) terminal.

 

Never connect a hot (red) output to

 

ground or to another hot (red) output!

9

 

 

 

Power down and disconnect units

 

from mains voltage before making

 

connections.

 

 

 

0

Do 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 series-con- nect an amplifier output with any other amplifier output.

Crest Performance 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, regardless 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 nor- mal 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 equipment power cord should be unplugged from the outlet when left unused for a long period of time.
