Description
TheSA202andSA202-RDTare20-watt
perchannel(4ohm)ClassABamplifi-
erswithmaximumgainof35dB.Input
optionsincludedualRCAjacksandaste-
reominijackforline-levelaudiosources
andaspeaker-level(amplified)inputfor
applicationswithlow-wattagespeakerout-
puts(e.g.,AVprojectortoexternalspeak-
ers).A15-voltpowersupplyisincluded
withtheSA202-RDT.Mountinghardware
isincludedandadaptstopole,surfaceor
securityattachmentinstallations.
Applications
Smallandcost-effective,theSA202is
engineeredforexternalamplificationwith
SoundTubeFPsound-focusingandother
high-fidelityspeakers.Additionalapplica-
tionsincludedigitalsignage,education,
pointofpurchase,museums,surgicalcen-
ters,AVcartsoranyapplicationwherea
smallamplifierisneededtoboostalimited
