We’re proud to introduce the first in our line of home theater receivers compatible with XM Satellite Radio - the new satellite radio format that’s creating a buzz nationwide. Incorporating the key attributes of quality home theater—a high current power supply; Onkyo’s proprietary receiver technologies like Wide Range Amplifier Technology (WRAT) and Optimum Gain Volume Circuitry; and the latest Dolby Digital and DTS surround sound decoders—the TX-SR573 provides the foundation for creating a memorable movie experience at home. The TX- SR573 will also comfortably accommodate HD-compatible components and connect with the latest digital displays. As an XM Radio®-ready receiver, the TX-SR573 gives you the option of connecting to more than 150 channels of uninterrupted music, news, sports, talk and entertainment, ensuring you’ll never be short of content. What’s more, you’ll be able to relish the high fidelity and power that lesser components fail to bring to radio transmission
