If I want to connect to a laptop, I can do it the same way, connecting to the headphone jack instead, right? Also, what's the best way to set this up if I will be plugging and unplugging into the laptop fairly often? Is it OK to leave the RCA end plugged into the amp and unplug the headphone jack for long periods of time? I am concerned about the headphone end if it's unplugged. Though maybe something like this would work well? http://www.guitarcenter.com/Hosa-Mono-1-4---Female----2-RCA--Male--Y-Cable-333091-i1128945.gc Then I could unplug a long extension cord whenever I like. Thoughts, guys? I'd like to get something today.
