Onkyo TX-8220 Analog Home Audio/Video Stereo ReceiverCategory: Best Audio Video ReceiverOnkyo TX-8220 Analog Home Audio/Video Stereo ReceiverEnjoy wireless connectivity and room-filling sound with the Onkyo TX-8220 Stereo Receiver. It features Onkyo's WRAT amplifier technology and produces up to 45W per channel at 8 Ohms for robust audio playback. Bluetooth connectivity is built-in to allow you to wirelessly stream music from compatible audio sources such as computers, smartphones, and tablets. For more traditional connectivity, the Onkyo TX-8220 has a digital coaxial, optical, four RCA, and a phono RCA input for connecting a variety of audio sources. A remote control is included as an added convenience.Bluetooth Allows Mobile Audio to Fill the RoomWith low-latency Bluetooth 4.1 wireless technology, you can stream almost any audio that's playing on your smartphone, tablet, laptop, or computer. The Auto Connect function helps make pairing and playing back your music quick and easy, with enhanced stability for a reduced loss in audio quality.Enhanced ConnectivityThe TX-8220 is equipped with inputs to connect a range of sources. Use Hi-Res Audio-ready digital audio inputs to route display or computer audio through to the speakers, line-level inputs for a CD player or DAC, and the MM phono input for your turntable. Enjoy room-filling reproduction of these as well as FM/AM radio and Bluetooth sources.Designed for Hi-Fi SoundPair the TX-8220 with your choice of speakers to add high-fidelity sound to everyday entertainment, from streaming audio to TV programs, vinyl, and CD. Its discrete amplifiers, large EI transformer, and customized capacitors are engineered to deliver ample driving power with low distortion. A high current grips the speaker cones for accurate control, helping to restore vitality and detail to music. Non-phase-shift circuitry, meanwhile, aids in focusing the audio image.High-Current, Low-Impedance DriveDynamic passages in music and film soundtracks can see impedance spike and dip dramatically for short periods. This can place up to 10 times the usual load on your amplifier, and if it can't meet power demands, sound quality suffers. Onkyo's high-current low-impedance WRAT (Wide Range Amp Technology) design uses an EI transformer to help drive your speakers accurately, even under heavy loads.AM/FM Tuner with 40 Memory PresetsScan, name, and save 40 AM and FM radio stations for one-touch recall anytime. Bring a variety of programming to your listening space, from news and sports to music and talk radio.Discrete Amplifier Design with Quality PartsUnlike amplifiers based on integrated circuit (IC) boards, Onkyo's discrete amplifiers incorporate hand-selected audio-grade parts into their design. The TX-8220 has fully discrete output stage circuitry with heavy-duty transistors to control running temperatures, lower distortion, and increase the life of the product.A/B Speaker Posts for Multi-Room AudioThe TX-8220 features two sets of speaker posts, allowing you to connect up to two pairs of speakers. The receiver is designed to drive either a single pair of speakers rated at 4 to 16 Ohms, or two pairs of 8- to 16-Ohm speakers, allowing you to enjoy the same audio source in two rooms at once, or to switch between two sets of speakers in the same room.Independent Bass, Treble, & Balance ControlsBass, treble, and balance controls are useful for optimizing the tonal characteristics of your music. These circuits let you fine-tune the sound to your own taste with no perceived loss in audio quality.
