Small, powerful and costeffective, theSA502 is
engineered for external
amplification with
SoundTube and other highfidelity speakers. Additional
applications include digital
signage, education, point of
purchase,museums, surgical
centers, AV carts or any
application where a small
amplifier is needed to boost
a limited source output
(e.g.,computers, A/V
projectors, etc.).
