A:AnswerYour Bose should have an auxillary plug in on the back. Using your remote, press and release until AUX appears on the display. Connect your device to the AUX IN connector on the back of your Wave Music System using a stereo cable with a 3.5 mm plug. you should be able to play your CDs. Hope this helps.
A:AnswerI have not run a turntable through the Bose unit. But, my past experience has taught me that the signal from a turntable is such that you don't get much volume out of whatever it is plugged into unless you use a pre-amp on the turntable signal.
A:AnswerThanks for posing us a question!
The Wave Soundtouch IV does have an AUX port and the option for an AUX input, so should be compatible with almost all AUX devices.
If you're unsure/ are doubtful of this, we would recommend trialing this in a Bose store to help ensure that you're 100% happy with this!
We hope this helps!
