If you watched my Orbitsound Bar A60 video review you will see why I love the remote. It's exactly the same remote with the P70. Check that video out here : (Orbitsound A60 Review) The P70 does have a very minimal on board display. Orbitsound have kept it simple here and that's a good thing. All you really need to know is what mode you are in and what the current volume, bass and treble levels are...and the P70 will tell you.
The on board controls are also kept to a minimum. Volume up, volume down and input mode selection. Exactly what you need. I actually own a Sony Sound base the HT XT1 and it sounds awesome but... No on board volume controls which is really frustrating. On the P70 you have exactly what you need to proceed listening will full control.
