verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
WRAT (Wide Range Amplifier Technology): The Onkyo TX-8020
Stereo Receiver features WRAT technology that uses low-negative-feedback circuit
topology for accurate signal reproduction, improved dynamic signal-to-noise
ratio, and better delivery of power peaks. The Onkyo TX-8020's discrete stereo
amplifier is rated at 50W x 2ch (8Ω, 20-20kHz, 0.08% THD).
Tone Control: The Onkyo TX-8020 offers independent Bass
(+/-10dB @ 50Hz) & Treble (+/-10 @ 20kHz) control to fine-tune your music.
You can also balance your music from left to right.
Analog Audio Inputs/Output: The TX-80520 is equipped with six analog
audio inputs and one analog audio input. This receiver contains no digital
Phono Input: Included in the six analog audio inputs, is a
Phono (MM) input with ground terminal.
A & B Speaker Terminals: The Onkyo TX-8020 stereo receiver
is equipped with A & B speaker terminals to connect up to two pair of speakers.
The receiver uses binding post connectors for the A & B speaker outputs. The
binding posts are not 5-way because a plastic collar prevents their use with
spade lugs; they will accept bare wire, pin connectors, and single banana plugs
(spaced too far apart for dual bananas).
Note: If you're using only one of the speaker sets (A or B),
choose the 4Ω setting if each speaker's impedance is 4Ω to less than 6Ω, or
choose the 6Ω setting if each speaker's impedance is 6Ω or more. If you're
using both of the speaker sets (A & B), choose the 4Ω setting if each
speaker's impedance is 8 to 16Ω.
Subwoofer Pre-Out: The Onkyo TX-8020 stereo receiver is equipped with
a mono subwoofer preamp output to connect a powered subwoofer.
Headphone Jack: When headphones are plugged into the
full-size 1/4" jack on the front-panel, the A & B main speakers are

built-in AM/FM tuner with manual, seek, and preset tuning. 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 then label
each preset with a 10 character name. The TX-8020 also lets you directly tune in
AM/FM stations using its remote control.
IR Remote w/ RI Remote Control Jack: The included IR remote control operates this unit
& compatible Onkyo cassette players and CD players. The 1/8" RI remote control jack
allows you to connect this receiver to compatible Onkyo components.
Display Dimmer: The display brightness has three settings;
Dim, Dimmer, and Normal.
Sleep Timer: From the remote, you can set the unit to
automatically turn off after as much as 90 minutes or as little as 10 minutes;
choices are presented in 10 minute increments.
Auto Standby: The stereo receiver will automatically go into Standby
mode, if there is no operation for 30 minutes with no audio/video signal input.
