I am looking for a 5.1 Surround Sound AV Receiver with DAB that also has a zone B facilty that can be used whilst ideally retaining the main room 5:1 set-up. I have looked at the Yamaha RVX481D but it is neccessary to go into the set-up menu to change from surround speakers to zone B and again to change back again. As a compromise I would be happy with the surround speakers not working when zone B is activated but the main system automatically changing back to 5:1 when zone B is de-activated (i.e. without having to go into the set-up menu). Can anyone advise a suitable receiver costing between budget £250 and £400?
