TM
dbx® incorporates high quality
mechanical fans in some products. All
mechanical fans have a limited life
expectancy. We recommend annual
inspection of fans for dust occlusion
and excessive noise. Fan assemblies
should be replaced after six to ten
years of use. Environmental factors
such as elevated temperature, dust,
and smoke can adversely affect
fan life. Systems exposed to these
conditions should be inspected more
frequently. Fan replacement can be
performed either at the factory or by
an experienced technician in the field.
Please contact dbx Technical Support
for more information on purchasing
replacement parts or product service.
dbx® has a policy of continued product
improvement and accordingly reserves
the right to change features and
specifications without prior notice.
