5.1-Channel Home Theatre Receiver/Speaker Package
If the four HDMI® inputs, Audio Return Channel, convenient HDMI-linked set-up display, and Dolby® TrueHD/DTS-HD Master Audio™ decoding haven’t already persuaded you, here are three more reasons to consider the HT-S4505 home cinema. Firstly, Onkyo’s acclaimed WRAT (Wide Range Amplifier Technology)—formerly a feature offered only on its higher-end models—is now included. This noise-reducing technology contributes to exceptionally good audio performance across a wide dynamic range. Secondly, this model features Audyssey 2EQ®, which calibrates the speakers and amp to match your room’s acoustics, thus perfecting the surround sound; and Audyssey Dynamic Volume®, which lowers the volume of irritating commercials while making movie dialogue easier to hear. Thirdly, the active subwoofer is designed for high output and very low power consumption, rounding out a compact, powerful speaker set. All this (and much more) adds up to what we think is the best-value, best-performing, best-equipped home cinema package around for the money.

Audio Return Channel and 3D Video via HDMI®
Four HDMI inputs on the HT-S4505’s receiver allow seamless integration of high-definition devices such as Blu-ray players, cable/satellite tuners, and gaming consoles. HDMI implementation on this receiver also supports an Audio Return Channel, allowing TV audio to be sent upstream to the A/V receiver. That means you can enjoy television programs in magnificent Onkyo sound. HDMI also supports 3D video and other popular high-resolution formats.
Direct Digital iPod®/iPhone® Connection for Cleaner Sound
The receiver’s front-panel USB port lets you play MP3 and AAC stored on an iPod/iPhone, and MP3, WMA, AAC, and FLAC audio files stored on a flash-memory device using the system’s own remote for track selection and playback. Your music will also sound much cleaner and clearer, as the audio signal is transported in digital form (rather than analog) via the direct digital connection.
WRAT (Wide Range Amplifier Technology) Delivers Higher Fidelity
WRAT is a suite of proprietary technologies Onkyo developed to improve signal-to-noise ratios, and enhance the fidelity of amplified audio. The technologies work to reduce noise across the frequency range, guaranteeing a clear, well-balanced performance. It does this by employing a low negative-feedback amplifier design; using “closed” ground-loop circuitry to cancel noise from individual circuits; and by ensuring high instantaneous-current capability to cancel reflex energy and impedance fluctuations from the speakers.
Enjoy Lossless High-Definition Movie Soundtracks
The receiver can decode Dolby® TrueHD and DTS-HD Master Audio™—two “lossless” Blu-ray formats that deliver a soundtrack identical to the studio master. The receiver also handles Dolby® Digital Plus and DTS-HD High Resolution Audio™. Dolby Digital Plus is designed to accompany HD video delivered via disc media, television broadcasts, and online content. DTS-HD High Resolution Audio, meanwhile, offers a higher bit and sampling rate than the core DTS technology.
Convenient Overlaid On-Screen Display via HDMI
The receiver’s overlaid On-Screen Display (OSD) feature makes changing the settings on your A/V receiver quick and easy. On-screen set-up menus appear overlaid on the video image you’re watching. This means you can adjust the settings immediately, without having to stop the program and switch to a different screen to access menus.
Audyssey Technologies Optimize Home Cinema Performance
The HT-S4505 comes equipped with three sound-enhancing Audyssey technologies.
(1) Audyssey 2EQ® tailors multi-channel audio for your home cinema speaker set-up by measuring three room positions and applying a resolution filter to the satellite speakers to correct for room acoustics.
(2) Audyssey Dynamic EQ® maintains a consistent bass response, tonal balance, and surround-sound effect at different volume levels, so you can enjoy the natural dynamics of your content regardless of the volume.
(3) Audyssey Dynamic Volume® automatically compensates for volume fluctuations in different audio content—for example, during commercial breaks—while optimizing the dynamic range.
Active Powered Subwoofer for More Powerful Bass Impact
To take full advantage of the impact of low-frequency sounds in your games, movies, and music, the HT-S4505 employs an active powered subwoofer. This type of subwoofer draws an independent power supply that leaves the AVR free to focus its power on the mid- and high-frequency sounds. This all-new down-firing subwoofer was developed to save energy (and money) by slashing power consumption by 80 percent over the 2011 models.
Advanced Music Optimizer to Enhance Compressed Digital Music Files
While MP3 or AAC files may sound fine through the headphones of your portable digital player, the limitations of these files can be exposed when played back through a quality home entertainment system. This is because a significant amount of high-frequency bit information is lost during the file-compression process. To counter this, Onkyo has designed the Advanced Music Optimizer to compensate for lost bit information and improve the quality of compressed audio signals. This results in a clearer and more expansive sound.
Get More Realistic Action with Four Different Gaming Modes
Select from four different optimized audio modes to match your gaming content for a highly realistic surround sound experience. Rock, Sports, Action, and RPG game modes will help to bring out the best in any soundtrack, from subtle ambient effects to thundering explosions.
