Comparison chart for Sony Receiver

4-ohm/8-ohm Switching -- Enables reliable operation with low-impedance speakers.
Discrete Output Transistors -- Amplifier refinement that offers high speed, high current capacity and low distortion.
Equal Power to All 5 Channels -- Left, Right, Center, Left-Rear, and Right-Rear get the same power output - important for theater-quality Dolby Digital and dts multi-channel surround sound.
Dolby Digital Decoder -- Enables digital surround sound that is far more dynamic, spacious and realistic. Generates digital multi-channel sound with separate discrete Left, Right, Center, Left Surround, Right Surround and (LFE) Subwoofer channels. Includes digital inputs for DVD, DTV and other products.
dts (Digital Theater System) Decoder Built In -- Enables multi-channel digital surround sound that is dynamic, spacious, and realistic. Generates 5.1 discrete channels of sound for Left, Right, Center, Left Surround, Right Surround, and Subwoofer.
Dolby Digital 5.1-Channel Inputs - Enables you to connect Sony's SDP-E800 Dolby Digital Processor or a DVD Player with built-in processing. So you can enjoy the benefits of this amazing new technology.
Surround Control for 5.1 Channel Inputs -- The Sony STR-DE535, DE435, and DE335 enable you to connect a 5.1-channel source and still enjoy the benefit of the Receiver's powerful Digital Signal Processing, as well as Digital Cinema Sound processing. You retain comprehensive control.
Dolby Pro Logic Decoder -- The classic system that brings home the excitement and emotional impact of movie sound tracks. Decodes and amplifies the surround channels already encoded in most movie videocassettes and laser discs, many TV dramas, and sports broadcasts.
Multi-Room Audio Output -- Now you can "share" music that's loaded into a 300-CD MegaStorage^� changer with other rooms in the house! Sony's STR-DE935 can simultaneously deliver music from two different sources into two different rooms. The STR-DE935 offers a multi-room audio output with independent source selection. This line-level output can deliver your second source to a bookshelf system or a second stereo receiver, such as the STR-DE135.
Station Memo Display -- Memory system that lets you assign names for your preset stations, like ROCK, CLASSICAL, NEWS or JAZZ.
2-Way Pre-Programmed LCD Remote Commander^� Unit -- Picking up the LCD Remote of Sony's STR-DE935 and DE535 is like holding your entire A/V System in the palm of your hand. Your system's information appears on the remote screen, including AM/FM station preset name, surround sound modes and even disc titles with compatible Sony CD Players and MiniDisc Decks. Not only does this remarkable Remote send commands to the Receiver, but the Receiver sends status messages and data back to the Remote! It's true 2-way communication, for the fastest, easiest, most dynamic system control you've ever experienced.
Pre-Programmed Remote -- Lets you operate many non-Sony units from the Receiver remote.
Digital Signal Processing (DSP) -- Circuit that reproduces movies and music in the appropriate setting: movies in a Theater, classical music in a Hall, rock music in an Arena, for example. Through the use of rear-channel stereo this advanced version of Digital Signal Processing spreads the rear speaker sound creating a huge soundstage rivaling professional theater installations.
24 Bit + 32 Bit DSP -- Behind Sony's advanced digital features are two remarkable digital processors. Dolby Digital, dts and Dolby Pro Logic decoding are handled by a dedicated 24-bit DSP engine of superlative performance. Unique Digital Cinema Sound modes, Virtual 3D modes and advanced parameter adjustments originate in a separate 32-bit DSP - for vastly better resolution. So you'll hear sound that's superbly realistic, supremely detailed.
Digital Cinema Sound System -- What is the ultimate reference for movie theater sound? It's the Hollywood dubbing stage - where directors go to mix, evaluate and approve a movie's final sound tracks. Now precisely this sound has been brought home, courtesy of Sony's Digital Cinema Sound system. These digitally recreated acoustic environments are based on actual measurements made at the Sony Pictures Studios dubbing stages in Hollywood. Which means that Sony Receivers make your movies sound exactly the way they were meant to be heard!
Digital Cinema Sound Virtual 3D Technology -- When it comes to rear speakers, there's a huge difference between the theater and the home. Theaters use an array of multiple side and rear speakers. Most home theaters use only two rear speakers. To bridge the gap, Sony's Digital Cinema Sound system offers Virtual 3D Processing. It helps correct for rear speaker limitations. For example, the Virtual Multi-Dimension Mode can generate and place the sound of up to five pairs of virtual rear speakers - using only two rear speakers. And Cinema Studio Extended modes let you enjoy the benefits of Virtual 3D and Cinema Studio processing simultaneously!
Soundfield Parameters -- Powerful 24 bit + 32 bit DSP enables you to vary even subtle aspects of the soundfield acoustic environments. Adjust room size, wall condition, reverberation time - even the row and number of your seat!
Variable Delay Time -- Adjusts the surround sound to match your listening room and speaker setup. Synchronizes the arrival of sound from front, center and rear speakers, for Dolby Pro Logic and Dolby Digital reproduction.
S-Video Inputs and Outputs -- Enables you to connect video equipment to your A/V Receiver at very high signal quality. S-Video keeps the black-and-white signal (luminance) apart from the color signal (chrominance) to maintain superior picture quality.
S-Link Interface -- Enables advanced A/V system convenience with compatible Sony A/V components. Benefits include 200-CD Changer information on the LCD Remote, Receiver Auto Function when you hit CD Play, for example, and Auto Power Off in the source component when you switch to another source.
