This past week, a client asked if he could connect a Bose Soundtouch Adapter directly to his speakers. The answer is a qualified no. Unless the speakers are self-powered with an aux input, connecting a Bose Soundtouch Adapter to a pair of passive speakers will not work. Passive speakers require power and the Adapter supplies audio signal not power. I further explained that the Bose SA-5 amplifier had Soundtouch ability built in and could power the passive speakers. He then questioned what was the purpose of a Bose Soundtouch Adapter? A Bose Soundtouch Adapter should be used to incorporate an existing non-Bose receiver or amplifier into your Bose Soundtouch system. Simply connect the Bose Soundtouch Adapter to the input on the receiver amp and then add the Adapter to your Soundtouch app. For more information, please visit our website @ www.wbsouth.com.
