Remote Control

Adding More Options to the Home Theater Experience
Want more than a superb balance of precise surround sound processing, powerful amplification and signal-enhancing technologies to bring out the very best in your home theater? The TX-SR504 goes above and beyond by giving you the capability to switch up to three high-definition components for simple connection to HDTVs. So, on top of sensational DVD movies and your own music catalog, the TX-SR504 easily integrates recorded video content, live high-definition broadcasts and the most gripping console games. While this receivers sophistication cant be denied, its also designed to make operating your home entertainment a stress-free, simple exercise. A perfectly laid out rear panel features color-coded ports, while the preprogrammed RI (Remote Interactive) remote control and accessible front panel controls do all the work for you. In more ways than one, the TX-SR504 will set you up for the best home theater entertainment yet.
Wide Range Amplifier Technology (WRAT) WRAT is the backbone of the TX-SR504s amplifier design and is centered on three core elements: 1) A low-negative-feedback design that ensures a fuller sound at higher frequencies; 2) Closed ground-loop circuits that mitigate individual circuit noise and keep the ground potential free of distortion; 3) A high-instantaneous current capability that effectively handles reflex energy from the speakers and impedance fluctuations to offer dynamics similar to those experienced in a movie theater. WRAT ensures the audio performance necessary for a range of video content with surround sound, as well as providing a solid platform for reproducing music sources like DVD-Audio, Super Audio CD, PCM CDs, and digital files like MP3s. Component Video Switching (50 MHz) with HDTV Connectivity With three component video inputs, you can have up to three of todays latest A/V componentsthink DVD/universal players, cable/set-top boxes, DVRs and the latest gaming consoles like the Xboxconnected simultaneously for output to the latest high-definition displays. With a frequency range out to 50 MHz, you have more than enough bandwidth to pass a progressive scan DVD signal (at least 12 MHz needed) and a 720p signal (at least 37 MHz needed) to high-definition displays with no video signal deterioration. Also, the convenience and simplicity of one component video output for all souces fit well with the TX-SR504s focus on ease-of-setup. Incorporating the Most Advanced Surround Formats Available The TX-SR504 has the onboard codecsDolby Digital EX, Dolby Pro Logic IIx, DTS-ES, DTS 96/24 and DTS Neo:6to effectively reproduce stereo and multichannel sources in enveloping 6.1 or 7.1 surround sound. And with the upcoming release of HD-DVD and Blu-ray Disc, Dolby Digital and DTS have prepared audio formats that represent the future of digital audio entertainment. By connecting an HD-DVD or Blu-ray Disc player with the respective high-definition audio codecs to the TX-SR504 via its 7.1-multichannel inputs, you will be able to enjoy superior audio quality with a bit-rate of up to 1.5 Mbps*, almost twice that of existing codecs. The new codecs are back-compatible with existing codecs.

Extended Crossover Adjustment Crossover control determines the frequency at which the subwoofer takes over bass-reproducing responsibilities from the main speakers. If the crossover is too low, therell be a dip in the mid-bass response. If its too high, therell be frequency duplication (resulting in a muddy bass sound). Your rooms acoustical environment can also influence the crossover setting. The TX-SR504 lets you choose from a wide range of frequencies40/50/60/80/100/120/150/200 Hzwhich enables you to accurately set the correct crossover for different speaker packages. Youll also be able to better mix and match different speaker brands. Optimum Gain Volume Circuitry Conventional volume attenuation methods must initially drop a signal close to the noise floor at low volumes. Even though the signal is only tainted with a little noise, the amount increases when the signal is amplified. Onkyos Optimum Gain Volume Circuitry adjusts the gain so that less than half the amount of attenuation is necessary. This signal never comes close to the noise floor, and thereby eliminates the possibility of noise contamination that plagues conventional volume-attenuation designs. Rear Panel with Color-Coded Connections for Ease-of-Setup To get up and running quickly, the TX-SR504s rear panel is designed so that you can simply connect to your A/V components. Youll probably be making use of your component video inputs/output, which are conveniently located on the top left of the rear panel (as are the digital inputs for Dolby and DTS surround signals). You may also use the color-coded 7.1-multichannel inputs (perhaps to experience the splendor of Super Audio CD and DVD-Audio formats) to transfer a 7.1-multichannel signal. Last but not least, color-coded speaker posts aid in the stress-free connection of speakers.
