Summary: This was probably the first sound bar and I bought it about ten years ago. It's still going strong and the only addition was buying Yamaha's matching sub woofer. You might think this is really out of date except if you are like me and have mainly component equipment, or HDMI is problematic for whatever reason. The YSP1 has 2 component inputs and 1 component output. There are also 2 optical digital audio jacks and one RCA type digital audio input.
