Sony has positioned the HT-IV300 right in between a standard home theatre system and a high-end home theatre systems that comes with an AV receiver. So you won’t find a ton of inputs and output connectors to play around with, but in our opinion, they are more than enough for most homes. For starters, you have only two HDMI-in ports that let you connect the speaker set to a DVD player, a Blu-ray player, a gaming console, a laptop or even a HD set-top-box. You can also connect your HD set-top box directly to the speakers with the help of an optical input. This makes it easy to set up the speakers to enjoy your favourite TV shows in surround sound. It even lets you preserve the HDMI ports for other sources. The HDMI-out is also an ARC port, which also lets you save the need for another HDMI cable, running from the TV to the speakers. For audio output, you also have a coaxial and audio analog port.
