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 power-up to pre-
vent speaker damage if there are high
signal levels at the inputs.
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
series-connect an amplifier output
with any other amplifier output.
Crest Audio is not responsible for dam-
age to loudspeakers for any reason.
19. Do not ground any red (“hot”) ter-
minal. Never connect a “hot” (red)
output to ground or to another “hot”
(red) output!
20. Non-use periods. The power cord of
equipment should be unplugged from
the outlet when left unused for a long
period of time.
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.
22. To obtain service, contact your nearest
Crest Audio Service Center,
Distributor, Dealer, or Crest Audio at
201.909.8700 (USA).
