Features

WRAT (Wide Range Amplifier Technology): This technology uses low-negative-feedback circuit topology for accurate signal reproduction, improved dynamic signal-to-noise ratio, and better delivery of power peaks.

Component Video Switching: In addition to composite and S-Video switching, this unit can switch between high resolution component video sources. There are 3 component video inputs and 1 component video output; each input and output has jacks labeled "Y", "Pb" and "Pr". The component video inputs and outputs have a bandwidth of 5Hz to 50MHz.

Digital-to-Analog Converters (DACs): To decode and playback high-resolution recordings, this receiver is equipped with Linear PCM 192kHz/24-bit DACs on all channels.

Speaker Distance: The distance from your listening position to each speaker can be set in the receiver. The front speaker distance can be set from 1 to 30 feet in 1-foot increments. The center and subwoofer settings can be up to 5 feet more or 5 feet less than the distance you set for the front speakers. The settings for the surround left, surround right, surround back left, and surround back right speakers are each individually adjustable, and they may be up to 5 feet more or 15 feet less than the distance you set for the front speakers.

Speaker Levels: You can manually adjust the level of individual speakers during playback between -12dB and +12dB, and -15dB to +12dB for the subwoofer. These adjustments are temporary, and will be canceled when the receiver is turned off.

Double Bass: You can enhance the bass output by activating the Double Bass function. This function allows you to feed bass frequencies to the front left and right channels and to the subwoofer. Double Bass can be set only when the subwoofer is set to On, and the front speakers are set to Large.

Adjustable Crossover: This receiver has a built-in high-pass crossover for the speaker system. This setting is available when you tell the receiver that there is a subwoofer being used. The frequencies that you can choose from are: 40, 50, 60, 80, 100, 120, 150, and 200 Hz. Frequencies lower than the set crossover point are output by the subwoofer.

XM Ready: Using the optional XM Mini Tuner, the Mini Tuner Home Dock and an XM subscription, you can take advantage of the variety and sound quality of XM Satellite radio. XM offers over 170 digital channels of music, news, sports, and talk radio and even has weather and traffic information in several major markets. The channel number, channel name, artist name, and song title are listed on the TX-SR504's display and on the connected TV monitor. XM stations are stored as presets and recalled in the same way as AM and FM stations.

iPod Compatible: The DS-A1 or DS-A2 Remote Interactive Dock for iPod (item #'s 580DSA1 and 580DSA2) provide an interface between an iPod digital media player and Onkyo TX-SR504. Once the iPod is docked you can control basic functions such as volume control, play, stop, and skip via the Onkyo system's RI-compatible wireless remote control. The dock also charges the battery in the iPod, and allows you to view digital photos and video on an Onkyo home theater system.

Assignable Digital Inputs: The TX-SR504 has 4 assignable digital inputs (3 optical/1 coaxial) allowing you to specify which input source is connected to which digital input jack.

Multi-Channel Input: The receiver is equipped with a 7.1 multi-channel input for compatibility with external decoders or high resolution audio players such as DVD-Audio or SACD. The input consists of left front, right front, center, subwoofer, left surround, right surround, left surround back and right surround back RCA inputs.

Direct Mode: This mode delivers pure sound with minimum sound quality adjustment and filtration. The sound recorded for the right and left front channels is output to the right and left front speakers only and not output to the subwoofer or rear speakers.

Listening Modes: This receiver incorporates a wide variety of listening modes to bring you maximum enjoyment from your audio and video software. The listening modes include:

• Direct: audio from the input source is output directly with minimal processing
• Stereo: sound is output from the front left and right speakers and subwoofer
• Mono: sound is output from the front left and right speakers and subwoofer

CinemaFilter: Using the CinemaFilter you soften overly bright movie soundtracks. Movie soundtracks are typically mixed for a large theater (relative to your home theater) with lots of soft seats and thick curtains on the walls. Home theater settings often lack these high frequency absorbing wall treatments making the soundtrack sound too bright. CinemaFilter accounts for this and for many movies sounds more natural at home.

Late Night Feature: The Late Night feature limits the dynamic range of Dolby Digital recordings. Limiting the dynamic range makes it easier to find a volume that ensures the quiet sounds are not too quiet and the loud sounds are not too loud for night time listening. This allows you to comfortably listen to without the need to constantly adjust the volume to keep from waking family/neighbors. The choices are: Off, Low, and High.

Sleep Function: From the remote, you can set the unit to automatically turn off after as much as 90 minutes or as little as 10 minutes; choices are presented in 10 minute increments.

Display Dimmer: You can adjust the brightness of the display. You can select dim, dimmer, or normal brightness.

Remote Control

Multi-brand Remote: The supplied RC-647M wireless remote is a multi-brand remote. The remote is pre-programmed to operate Onkyo components, as well as other popular brands of equipment, including DVD players, satellite receivers, cable boxes, VCRs, and televisions.

Input and Output Notes

Multi-channel Input: The TX-SR504 has a multi-channel input for connecting a DVD player, a high resolution audio player (such as a DVD-Audio or SACD player), or an external decoder. The input consists of left front, right front, center, subwoofer, left surround, right surround, left surround back and right surround back RCA inputs. You can connect a component using only left and right audio jacks, if desired. In addition, there are composite and S-video jacks for this input. Note: The DVD input is included in the total of 7 A/V inputs.

Headphone Output: This receiver has a standard 1/4" headphone output on the front panel. All speaker outputs are muted when headphones are plugged in.

Speaker Outputs: There are color-coded binding post connectors for the left front, right front, center, left surround, right surround, left surround back, and right surround back speakers. The binding posts are not 5-way because a plastic collar prevents their use with spade lugs. The Zone 2 speaker terminals are also binding post connectors. The Front Speakers B terminals are spring clips.

RI Remote Control Jack: The 1/8" RI remote control jack allows you to connect this receiver to compatible Onkyo components.
