About this product

Product Information

For clear, crisp audio, the Sony STR-K840P 5.1-channel 100-watt receiver is a dynamo that can power audio output to multiple rooms within your home. Whether you are creating, extending, or just improving your current home theater setup, this surround sound system brings a lot to the table. Like many Sony home theater receivers, this model can be operated by a universal remote control and push virtually any standard speaker set to a loud volume. Featuring both stereo and 5.1-channel surround sound, it merges comfortably with both new and old hardware without requiring a complicated manual. This makes it a perfect replacement for an older receiver model that has stopped functioning while still leaving the door open for newer items to seamlessly integrate in the future.A great addition to any home theater system, the Sony STR-K840P packs a wallop with its 100-watt amplifier output power and 8-ohm resistance. This can easily get the entire room rumbling when paired with a capable set of speakers. Good for more than just explosions, though, you can balance the theater system audio with finesse through the controllable bass, mid, and treble frequency levels and use of the DTS, Dolby Digital, and Dolby Pro Logic II decoders. The unit also has AM/FM tuner bands so you can tune in to your favorite radio broadcasts at home. For those that only plan on playing high-fidelity audio, rest assured that your needs are met with a complete frequency-response bandwidth that ranges from 10 to 50,000 Hz, ensuring complete sonic representation from tweeters to the subwoofer.On a more technical note, the input impedance of this Sony receiver is 50 ohms. This means that it pulls voltage without the dips that some receivers struggle with while allowing it to maintain an input sensitivity of 250 mV. There are also several standard connector types included on this Sony STR-K840P receiver, covering everything you need. It has a 5.1 channel line for easy surround sound, an SPDIF input and output to cover optical digital audio, composite video/audio outputs, a 3.5-millimeter jack for headphones, and the subwoofer line out to make sure there is plenty of bass.This Sony STR-K840P receiver is highly customizable to your particular ear. There are a number of pre-programmed DSP presets to help make it quick and easy to setup for the best sound. EQ controls can always be fine tuned to produce superior tones no matter how the acoustics are laid out in a room. However, for an immediate setup, the presets are more than capable of providing a great experience. Once the system is up and running, a built-in digital display helps make reading the information on the Sony STR-K840P receiver a breeze while the option to use any universal remote makes bringing the receiver into any surround sound system a simple affair as well.
