We have changed the specification in order to comply the regulation, so it does not matter to part of customer who bought the product which was made before January 2015.

WRAT (Wide Range Amplifier Technology)

The TX-8050 employs a host of proprietary Onkyo technologies to ensure optimal audio performance.

Low Negative-Feedback Design

Too much NFB makes a system susceptible to counter-electromotive force from the speakers, resulting in a drop in perceived sound quality. To avoid this, Onkyo focuses on improving the frequency response and reducing distortion, without relying so much on NFB.

Closed Ground-Loop Circuits

The TX-8050 employs a sophisticated closed-circuit design in which each circuit has a separate link to the power supply. This helps to cancel individual circuit noise and keep the ground potential free  of distortion.

HICC (High Instantaneous-Current Capability)

HICC enables an amplifier to immediately cancel the speakers’ reflex energy and instantaneously send out the next signal. The same high current required to achieve this also supports the amplifier’s ability to handle speaker impedance fluctuations.

Network Capability Delivers Internet Radio and Network Audio Streaming via Ethernet

As one of Onkyo’s new breed of receivers that can link directly to the internet or to your home PC via a local network, the TX-8050 takes streaming audio and internet radio to a whole new level. MP3, WMA, WMA Lossless, FLAC, WAV, Ogg Vorbis, AAC, and LPCM audio files can now be played back through your main system with unprecedented power and fidelity. The TX-8050 also brings to life a huge array of internet radio channels from Last.fm* and vTuner. As well as being compatible with earlier platforms, the receiver is compatible with Microsoft’s Windows™ 7 platform, which includes the DLNA 1.5-specified “Play To” media-streaming feature.
*Availability of services depends on region.

Direct Digital Connection of iPod/iPhone via Front-Panel USB Port

The TX-8050’s front-panel USB port lets you access MP3, WMA, WMA Lossless, FLAC, WAV, Ogg Vorbis, and AAC audio files stored on a USB flash drive or iPod/iPhone. As the audio signals are transported in digital form, rather than analog, there is much less chance for signal degradation. End result: your music sounds cleaner and more faithful to the original. A further benefit of the USB input is that it lets you use the system’s remote controller to play back audio files on the connected device.

Play Your Audio Sources in Two Different Rooms

Zone 2 pre-outs on the TX-8050 allow you to send a stereo audio signal to a second room equipped with an amplifier and a pair of speakers. You can either enjoy the same source in both rooms, or play a different source in Zone 2.

Universal Port for Single-Cable Connection of Onkyo Peripheral Devices

A proprietary Universal Port located on the rear side of the TX-8050 lets you connect an optional UP-A1 Dock for iPod/iPhone or UP-DT1 DAB+ Radio Tuner. A key advantage of the Universal Port is that it accepts video and audio signals through the same cable that sends a power supply from the receiver to the device. Net result: more connectivity, less cable clutter.
