The SPA-3 is an externally mounted two-channel precision attenuator

accessory for DataPort-equipped QSC amplifiers. With pushbutton pro-

gramming and digital gain control, it offers precise, secure, and repeat-

able attenuation settings from 0 to 32 dB. It features optional input iso-

lation transformers custom-made for QSC by Jensen, providing superb
