Samsung WAM 250 Smart HUB Wireless Home Audio System with Bluetooth - Multiroom Speaker for Living Room, Bedroom & Home Theater

Its a simple black box that you plug into your wired network - either your router or a switch. It has two network ports (100/mb) either will do. Second is if you want to connect something else to you network. You can use up to two of these to extend the range within your house or garden like a wireless repeater for speakers.The best way to set it up is to pair the hub first with your phone (iphone/android) - it not obvious initially that it is paired but if you look in the phone app settings it will tell you it is.Once the hub is paired with your phone (press a small switch on the back of hub to put it in paring mode - lights flash on the front) you just need to turn on your speakers (i did it one at a time with the speakers within a couple of feet of the hub) the R6's i have flash red for a few seconds and then a French sounding woman's voice tells you the speaker is connected and the indicator light goes blue. Nothing more difficult than that :)Once paired you can switch off your speaker and then move them to another location in the house - power them up and they take the same few seconds to re link with the hub. If they dont its probably because you have them to far away and the signal is to weak.The phone app (Samsung multi room) is quite good (although lacking some feature i would like) - you can name individual speakers, send different music to each one - or group them all together so they all play the same music. Also if you have 5(6) speakers you can set them up for 5.1 surround sound - not tried this as only have three.Music can come from lots of locations internet - streaming services like spotify, local DLNA/media server in your house and radio like last.fm.oh and the sounds good as well :)
