A:AnswerYes. The speakers are not attached to the receiver. The speakers connect to the receiver via small gauge speaker wire, which I recall it is about 2-3 feet long. You could also purchase additional speaker wire and move the speakers as far from the unit as you like.
A:AnswerThe manual doesn't specifically state the USB port's charging capability, though I did hook up my Sansa Clip, and it started charging - that is a low-amp device, though. I don't think I'd risk hooking up a high-amp device like a tablet.
A:AnswerThis shelf stereo system does have the option of connecting an external device using the red/white RCA type connections. If your cassette player uses these connection types, or can be adapter to this, then you would be able to connect them.
A:AnswerHello BrandiC, the "random play" function is integrated on the shelf system and only works for CD format not when playing MP3 format, however the shuffle feature is on the Ipod and the shelf system is a mere speaker system when using it for the Iphone so it will play what the Ipod is sending in the order the Ipod sends it.

A:AnswerHello Dee2648, you can hook up any speakers you like as long as the connection and the wattage match, however the shelf system is not designed to play each speaker separately. Omar S. - Insignia Support.
