Yamaha Digital surround sound processor.
Simply plug into an existing hifi system and this unit turns it into an excellent quality home cinema surround sound system (centre and rear speakers required).
Hardly been used since I bought from new so in immaculate condition. Has been stored in a cupboard since my daughters were born and now surplus to requirements.
