High-Current Discrete Amplification: The Onkyo TX-8220 stereo receiver
utilizes high-current discrete amplifiers, a massive EI transformer, and
customized capacitors to deliver ample driving power with low distortion.
Onkyo's high-current low-impedance WRAT design uses a massive EI transformer to
drive your speakers accurately, even under heavy loads. High current
amplification grips the speaker cones for more accurate control, restoring
vitality and detail to music. Non-phase-shift circuitry, meanwhile, clearly
focuses the audio image.
192kHz/24-Bit DAC (PCM1754): The Onkyo TX-8220 stereo receiver
utilizes a 192kHz/24-Bit digital-to-analog converter (DAC) from Texas
Instruments (TI) for excellent signal-to-noise (S/N) and low-noise performance -
so your music sounds clear, full of detail, and natural.
Tone Controls + Direct Mode: Bass (100Hz), Treble (10kHz), and Balance
controls are useful for adjusting the tone characteristics of your music for
satisfying the response with practically any type of speaker. These carefully
designed tone circuits let you personalize sound to your taste with no perceived
loss in audio quality. You can also select Direct mode, which bypasses the Tone
control circuits for the purest sound possible as the artist intended.
Analog (Including Phono) & Digital Inputs: The Onkyo TX-8220
stereo receiver is outfitted with both analog & digital audio inputs. There are
five stereo RCA analog audio inputs (including a MM Phono input with ground
terminal). There are two digital audio inputs - one optical (toslink) digital
input and one coaxial (RCA) digital input. The digital inputs support 2ch PCM
only (not compatible with Dolby Digital/DTS or other multichannel audio
Bluetooth Audio Streaming: Built-in Bluetooth 4.2 with support for
A2DP allows you to wirelessly stream your music library, music apps, podcasts,
audiobooks, and other audio content on your Bluetooth source device (such as
your smartphone, tablet, or laptop) to the Onkyo TX-8220 stereo receiver. The
unit supports SBC and AAC Bluetooth audio codecs. You'll continue to use your
Bluetooth source device to control playback and search functions, as well as
view song/artist information. You can pair up to 8 devices, but only one can be
connected and played back at a time. Once paired, the TX-8220 will automatically
connect with the last device connected when in range (approximately 32'). You
can also set the receiver to automatically switch to the Bluetooth source input
when a wireless Bluetooth connection is made.
AM/FM Tuner: With the built-in tuner you can enjoy AM and FM
radio stations. You can store your favorite stations as presets for quick
selection. You can store a combination of up to 40 of your favorite FM/AM radio
stations as presets. You can even register a custom name (up to 8 characters)
for each preset.
A/B Speaker Outputs: The TX-8220 features two sets of binding-post
speaker terminals enabling connection of two pairs of speakers. The receiver is
designed to drive either a single pair of speakers rated at 4-16Ω,
or two pairs of 8-16Ω speakers, allowing you
to enjoy the same audio source in two rooms at once, or to easily switch between
two sets of speakers. The binding-post terminals will accept bare wire (up to
10AWG), pin-connectors, and banana plugs (single only).
Line-Level Out & Sub Pre-Out: The Onkyo TX-8220 is equipped with
a stereo RCA line-level output for connecting a recording device. It also
features a mono-RCA subwoofer pre-out for connecting a powered subwoofer. The
subwoofer pre-out is full-range, so you will need a powered sub with a built-in
low pass crossover.
Headphone Jack: A front-panel 1/4" headphone jack allows you to
connect a set of headphones for private listening. Once a set of
headphones are connected, the stereo receiver's A/B speaker outputs are
Remote Control: The Onkyo TX-8220 comes with an IR remote
for wireless operation of the stereo receiver. The remote is not designed to
operate other audio equipment and will not control connected Bluetooth source
Front-Panel LCD: The Onkyo receiver features a front-panel LCD that
indicates Source Input, Station Number, Volume Level, and Menu Selection. The
front-panel LCD will not display song/artist/album info from connected Bluetooth
source devices. You
can adjust the brightness of the display in 3-steps. There is no on-screen menu.
Sleep Timer & Auto Standby: You can set the receiver to enter Standby
mode automatically when the specified time (10-90 minutes) elapses. The stereo
receiver can also be set to automatically enter Standby mode after 20 minutes of
inactivity without any audio input signal.
