The Sony STR-DH590 is the central point of your home cinema. You can connect multiple devices to the AV receiver, such as your television, Blu-ray player, and speakers. The device transmits 4K images to your TV. When your TV supports this format, you can view sharp images. Use the integrated measuring microphone to adjust the sound to the room you're listening in: a small room needs different tones than a large room. Use your phone or tablet to wirelessly stream your music to the amplifier with Bluetooth. This way, you can put on your favorite song from the comfort of your chair.
