Just thought I would share this with members just purchased a ks Bluetooth adapter new for £9.99 from Sainsbury's plugged it into the left and right inputs on the back of the kn6000 keyboard with adapters and works great connects my phone to the kit and plays out through the keyboard speakers and my amp and speakers,play songs from youtube just find the key you control volume from your phone/tablet/laptop and the volume on the keyboard turns just the keyboard up so you can play at any volume above the song. Sounds great quality through the keyboard speakers. Great for the price can be used in any aux port and then the device will connect to bluetooth.
