TX-SR304E

5.1-CHANNEL HOME THEATER RECEIVER

Available in Silver

Proving that Entry-Level Home Theater isnt about Limitations
Youll find very little differentiation between most entry-level home theater receivers: passable performance, negligible processing capabilities and little (if any) versatility. The TX-SR304E 5.1-channel home theater receiver doesnt follow that well-trodden path. By giving you the connections to the A/V components on everyones lips todayHDTVs, digital video recorders, gaming consoles, etcthe TX-SR304E wants to broaden your entertainment possibilities, not limit them to basic DVD and CD playback. Naturally, youll want the audio quality associated with the Onkyo name. Thats why weve included the circuitry and quality parts found in other Onkyo home theater receivers: Optimum Gain Volume Circuitry, 192 kHz/24-bit DACs, a 32-bit DSP chip, and an H.C.P.S. (High Current Power Supply) transformer. Finally, keeping in line with whats really important, the TX-SR304E provides a user-friendly, accessible solution to home entertainment.
Component Video Switching (50 MHz) with Single Connection to HDTV 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 deterioration on the video signal. Also, the convenience and simplicity of one component video output fit well with the TX-SR304Es focus on ease-of-setup. 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. 192 kHz/24-Bit Digital-to-Analog Convertors (DACs) for All Channels The TX-SR304E incorporates 192 kHz/24-bit DACs on every channel. With a much higher resolution than the incoming signal, these DACs enable the TX-SR304E to generate more accurate audio playback. Also, the DACs 128x oversampling rate optimizes the signal-to-noise ratio and increases clock jitter tolerance. With Onkyos emphasis on audio processing with minimal signal noise, the inclusion of quality parts is a definite plus at the entry level.
CinemaFILTER The tonal balance of a film soundtrack will be edgy and bright when played back over audio equipment in your home. This is because film soundtracks are designed to be played back in large theaters using different equipment. CinemaFILTER restores the correct tonal balance for watching a movie soundtrack in your smaller home theater. CinemaFILTER can be used with DTS and Dolby listening modes, and is easily activated from your remote control. Wide-Ranging 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-SR304E 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 manufacturers speakers. Rear Panel with Color-Coded Connections for Ease-of-Setup To get up and running quickly, the TX-SR304Es 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 5.1-multichannel inputs (perhaps to experience the splendor of Super Audio CD and DVD-Audio formats) to transfer a 5.1-multichannel signal. Last but not least, color-coded terminals aid in the stress-free connection of speakers.
