Installation ( see rack mounting section if applicable )Ventilation. The most important installation consideration is ventilation. The 9BSST is a convection-cooled amplifier.Unrestrictedair-flowacross itsheatsinks isamust.For this reasondonot installanythingdirectlyabove it.Allow3.5”(2u)to5”(3u)inchesofspaceaboveandtothesidesofthisamplifier.Donotinstalldirectlyaboveotherheatgeneratingequipment.Shouldyourinstallationconditionsbeconstricted,thenadditionalforcedair-coolingmaybenecessary.Brystoncanprovideanoptionalfanpackageifrequired.Any9BSSTchannelsthermallyshuttingdownduringoperationindicatesinsufficientcooling,andaremedymustbefoundforcoolingtheamplifier.Provideaminimum6”spacetotherearofthe9BSSTforventilationanddressingcablestoandfromtheamplifier.Never operate the 9BSST in a vertical position.
