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.

HDMI Switching: The TX-SR505 has two HDMI inputs and one HDMI output for connecting DVD players, HDTV set-top boxes, and other video components to your TV or projector. The receiver's HDMI circuitry is a switching pass-through design, and will pass video and 2-channel (stereo) digital audio through to the TV. However, if you want to listen to the soundtrack through the speakers connected to your receiver, you must make a separate analog audio connection (for stereo listening) or digital audio connection (for Dolby Digital 5.1 surround). The HDMI inputs are compatible with DVI, so TVs and displays with a DVI input can be connected by using an HDMI-to-DVI adapter cable, along with audio cables. The receiver uses HDCP (High-bandwidth Digital Content Protection), so only HDCP-compatible components can display the picture. The HDMI inputs can accept and switch 480i, 480p, 720p, 1080i, and 1080p signals to a TV, monitor, or projector. Each of the HDMI inputs can be assigned to any of the three rear panel A/V inputs (DVD, VCR/DVR, CBL/SAT).

Component Video Switching: In addition to HDMI, composite video, and S-Video switching, this unit can switch between high definition component video sources. There are 3 component video inputs and 1 component video output. 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 192kHz/24-bit DACs.

Automatic Speaker Setup: With the supplied speaker setup microphone, the Audyssey 2EQ Automatic Speaker Setup function can measure and correct for the acoustics in your listening room. The speaker setup function measures the test tone output by each speaker and automatically determines the number of speakers connected, their sizes, crossover frequencies, and the distance from each speaker to the listening position. The supplied microphone is approximately 2" in diameter, 1" tall, and has a 19.5' cable that plugs into the front of the receiver. There is a threaded insert on the bottom of the microphone so it can be mounted on a tripod for accurate listening position placement. Three listening position measurements are taken, one primary and two secondary, to optimize the surround effect for a broad area. If you wish to setup the speakers manually, you can follow the procedure for Speaker Configuration.

Speaker Distance: The distance from your listening position to each speaker can also be set manually. 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 (30 feet max). 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 (30 feet max).

Speaker Levels: You can manually adjust the level of individual speakers between -12dB and +12dB; -15dB to +12dB for the subwoofer.

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 any of the speakers set to Small. This setting is available when the subwoofer is set to Yes. 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.

Equalizer: The EQ function offers three options:

• Off: flat response
• Audyssey: adjusts the frequency response of all speakers to correct the effects of room acoustics, based on measurements taken using the included microphone
• Manual: the five band equalizer can be adjusted independently for each of the seven full range speaker channels (front, center, surround, and surround back), the EQ bands are centered at 80, 250, 800, 2500, and 8000 Hz (subwoofer EQ bands are centered at 40, 80, and 160 Hz) they are adjustable from -6 to +6 dB in 1 dB increments

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-SR505. 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-SR505 has 4 assignable digital audio inputs (2 optical/2 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.

Audio Sync: Occasionally the audio and video signals are not properly synchronized, typically when using a progressive scanning DVD player. You can correct this by delaying the audio; options are 0 (no delay) to 100 milliseconds, in 20 millisecond steps.

B Speaker Outputs: The B speaker outputs can be used to power speakers in a different room, creating a second zone. When the B speakers are turned on, the main room is limited to 5.1 channel output.

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, center, 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

Dolby Pro Logic II & IIx Music Modes: While listening in the Dolby Pro Logic II or IIx Music format, there are three further enhancements you can adjust:

• Panorama: broadens the front stereo image to the surround speakers to provide a wraparound effect, especially effective when there is limited output from the surround channels, panorama can be turned on/off in the menu
• Dimension: allows you to move the sound field forward or backward
• Center Width: allows you to adjust the width of the center channel

Center Image: In the DTS Neo:6 Music mode, the Center Image feature adjusts the output of the left and right channels relative to the center channel, allowing you to make the center channel more or less dominant as needed. This improves the image of the center channel, especially when the listener is off-center. Adjustment varies from 5 (nothing subtracted from the L/R channels) to 0 (L/R channel output is cut in half).

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.

Input Display: The name displayed for most inputs is fixed (DVD, VCR/DVR, etc), but the Tape and CBL/SAT input displays can be changed. Tape can be changed to MD, CDR, or Dock and CBL/SAT can be changed to Dock. These settings also effect the Remote Interactive (wired remote) codes output to other connected components.

Display Dimmer: The display brightness has three settings; Dim, Dimmer, and Normal.

Remote Control

Multi-brand Remote: The supplied RC-681M 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
