how many units can be hooked up ?
i need a new receiver, and have 4 componants to hook up,can this accomadate all ?
It depends on what kinds of video outputs your components have. This has four HDMI inputs, one RCA component, and one coaxial input, plus two optical inputs. So, if you have a bunch of older components with standard RCA video outputs, then you are going to have a problem. But if you have components for audio with RCA outputs, then the receiver should be able to handle three. You really need to have someone knowledgeable help you with this.
