Network & Tuner Functions
High-Quality Sound: The Onkyo TX-8050 network stereo
receiver employs a host of technologies to ensure optimal audio
- WRAT (Wide Range Amplifier Technology): This
technology uses low-negative-feedback circuit topology for accurate
signal reproduction, improved dynamic signal-to-noise ratio, and
better delivery of power peaks.
- Low Negative Feed Back Design: Too much NFB
(negative feed back) 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 cloAsed-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
- 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.
Anti-Vibration Chassis: The Onkyo TX-8050 features
an aluminum front-panel & anti-vibration oval chassis to prevent
resonance which could lead to distortion.
Discrete Amplifier Design: The Onkyo TX-8050 stereo
receiver features a discrete amplifier design with massive EI
transformer. The stereo amplifier is rated at 80W x 2ch (8Ω, 20-20kHz,
Listening Modes: This receiver incorporates a wide
variety of stereo listening modes to bring you maximum enjoyment from
Listening Mode || Description |
Stereo || Sound is output by the front left & right
speakers, plus subwoofer with tone control. |
Music Optimizer || The Music Optimizer function enhances the
sound quality of compressed music files. The Music Optimizer
function only works with PCM digital audio input signals
with a sampling rate below 48kHz and analog input signals |
Direct || In this mode, audio from the input source is
output without any additional audio processing. This mode
delivers pure sound with minimum sound quality adjustment
and filtration. |
Pure Audio || In this mode, the display and video circuitry
are turned off and the tone controls are bypassed,
minimizing possible noise sources for the ultimate in
high-fidelity reproduction. |
Mono || Use this mode when watching an old movie with
a mono soundtrack. |
Tone Control: The Onkyo TX-8050 offers independent
Bass (+/-10dB @ 50Hz) & Treble (+/-10 @ 20kHz) control to fine-tune your
IntelliVolume: The IntelliVolume setup function
allows you set a volume correction value for each source, to prevent
large jumps in volume when switching from one source to another. This
feature eliminates the inconvenience of manually readjusting the volume
control each time you switch from a source with a weak signal to a
source with a strong signal and vice versa.
A & B Speaker Terminals: The Onkyo TX-8050 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, single banana plugs, and dual banana plugs.
Impedance Switch: 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.
Analog Audio Inputs/Outputs: The TX-8050 is equipped
with 7 analog audio inputs (3 audio only/4 AV in). There is also two
analog audio outputs (1 audio only/1 AV out).
Phono Input: Included in the 7 analog audio inputs,
is a Phono (MM) input with ground terminal.
Digital Inputs: The Onkyo network stereo receiver
features 4 digital audio inputs. There are 2 optical (toslink) digital
inputs and 2 coaxial (RCA) digital inputs. The receiver's digital inputs
do not support multichannel audio signal; PCM signal only.
Preamp Outputs: The Onkyo TX-8050 network stereo
receiver employs a mono-subwoofer preamp output, a stereo preamp output,
and a Zone2 preamp output.
- Subwoofer Pre-Out: The Onkyo TX-8050 network
stereo receiver is equipped with a mono subwoofer preamp output to
connect a powered subwoofer.
- Stereo Pre-Out: If you want to use a separate
power amplifier and use the receiver as a preamp, simply connect the
receiver's stereo preamp-output to your amp's input, and connect all
speakers to the power amplifier.
- Zone2: 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. You can
choose from analog, USB, or Network sources. Digital inputs (both
optical/coaxial) cannot be output to Zone 2. You are able to adjust
the volume from either the Onkyo stereo receiver or from your Zone 2
Note: You must currently be listening to a USB
device or Network audio source in the Main Zone to initially select
USB or Network as a source in Zone 2 or Zone 3. Then you can switch
the Main Zone to any source you desire. You cannot select different
AM/FM radio stations or listen to USB and Network content in
separate Zones at the same time.
Headphones: When headphones are plugged into the
full-size 1/4" jack on the front panel, the A & B main speakers are
automatically muted (the Powered Zone 2 speakers are not muted). When
you connect an iPod or iPhone to the USB port on this receiver, no sound
will be output from the headphone jack.
Composite Video: Although not a surround sound
receiver, the TX-8050 does employ composite video inputs & outputs; so
it can be used in a basic A/V system.
- 4 Composite Video Inputs: There are 4 composite
video inputs to connect your audio/video devices to the receiver.
- Composite Video Record Output: There is a
single composite video record output for recording purposes.
- Composite Video Monitor Output: There is a
single composite video monitor output to connect to your television.
Note: The TX-8050 does not contain any
S-video, component video, or HDMI inputs/outputs.
