Aventage Series: The Aventage line of Yamaha AV receivers is
based on the audio design concept of providing a massive, full-bodied sound for
movie sound effects and the accurate reproduction of music sources. By expertly
harmonizing traditional and advanced technologies, every factor that affects
sound quality, from materials & parts construction to circuitry layout,
vibration damping, and "fine-tuning" the sound, is handled with no other thought
than to achieve the best possible audio quality. As a result, every Aventage
receiver has the ability to reproduce the most subtle details of high-definition
sound, so that listeners can enjoy a truly high-class sound studio experience at
- High Drive Amp Technology: A fully discrete power
amplifier helps maximize sound and minimize distortion of the receiver. The
Yamaha RX-A870 AV Receiver is equipped with a 7-channel amplifier rated at
100 watts (into 8-ohms, at 20-20kHz, with 0.06% THD, driving 2 channels)
which provides high dynamic power with low-impedance drive capability.
- High Purity Pre-Amplification: The Yamaha RX-A870 uses
high quality, audio-grade Burr-Brown 192kHz/24-bit digital-to-analog
converters for all channels to maximize sound quality. The AV receiver also
utilizes low-jitter PLL circuitry to help optimize sound imaging. The result
is a more dynamic sound with greater detail and less distortion.
- Independent Power Supplies: Independent power supplies
are used for the receiver's analog and digital circuitry to prevent digital
noise from affecting analog circuitry. These power supplies are highly
efficient and result in less power consumption in standby mode.
- Aluminum Front-Panel: The aluminum front-panel is used
to effectively shield sensitive circuitry from external noise and electronic
energy generated by dimmer switches, fluorescent lighting, video monitors
and so on. This ensures optimum sonic performance in the widest range of
- Anti-Resonance Technology: The Anti-Resonance
Technology (A.R.T) Wedge is a fifth foot in the center of the unit. It
dampens vibrations from the power transformer, power transistors and heat
sinks, as well as vibrations that might be caused by the sound from the
- Advanced Design Feet: The feet of the receiver feature a newly
designed, high-density structure which utilizes two different kinds of
interior ribs (straight and curved) to enhance strength and damping
performance. Installation stability is improved and chassis resonance is
dispersed, effectively eliminating external vibration. The low-range
response is enhanced, while resonance peaks in the mid- and high-range are
reduced, providing dynamic sound and accurate reproduction.
Intelligent Amplifier Assignment: Intelligent Amp Assignment
automatically assigns amplifier channels of the Yamaha AV receiver to certain
speakers depending on what speaker layout has been selected and what content is
being played back. You can connect up to nine speakers to the AV receiver and it
will determine which seven speakers need amplification. You can choose from a
variety of amplifier speaker layout configurations.
- 7.1/5.1.2 Surround: In this configuration, up to nine
speakers (Front L/R, Front Presence L/R, Center, Surround L/R, & Surround
Back L/R) can be connected to the AV receiver. When Cinema DSP HD3 is on or a
Dolby Atmos soundtrack is being played, the two Front Presence or Dolby
Atmos speakers will be powered and not the two Surround Back speakers. When
Cinema DSP HD3 is off or Dolby Atmos is not playing, this situation is
reversed and the Front Presence or Dolby Atmos speakers turn off while the
Surround Back speakers are powered. Bi-amp and Zone 2 speakers are not
available in this mode.
- Dolby Atmos + Zone 2: In this setup, you can hook up a
5.1.2ch Dolby Atmos speaker system in the main room and a pair of speakers
in Zone 2 to the receiver. When Zone 2 is off, all seven channels of your
Dolby Atmos speaker system will be powered. However, when Zone 2 is turned
on, power to the Front Height, Overhead, or Dolby Atmos speakers will be cut
off and directed to the pair of speakers in Zone; limiting you to only 5.1ch
surround in the main room. Bi-amp & Surround Back speakers are not available
in this setup.
- 7ch + Zone 2: In this configuration, up to nine
speakers (Front L/R, Center, Surround L/R, Surround Back L/R, and Zone 2)
can be connected to the AV receiver. When Zone 2 is off, all seven channels
will be used in the Main Zone. However, when Zone 2 is on, power to the two
surround back channels will be directed to the two speakers in Zone 2 and
the Main Zone will receive five channels of power. The same or different
analog input sources/volume settings can be applied to both zones. Bi-amp,
Front Presence, & Dolby Atmos speakers are not available in this mode.
- 5ch Bi-Amp: Up to five speakers (Front L/R, Center, &
Surround L/R) can be connected to the AV receiver. The Surround Back
amplifier channels of the AV receiver are reassigned to bi-amp the front
speakers. A bi-amplification connection uses two amplifiers for one speaker.
One amplifier is connected to the woofer section of a loudspeaker while the
other is connected to the combined midrange and tweeter section. With this
arrangement each amplifier operates over a limited frequency range, making
its job easier. Zone 2, Front Presence, & Dolby Atmos speakers are not
available in this mode.
YPAO Sound Optimization: This unit employs the YPAO (Yamaha
Parametric Acoustic Optimizer), which automatically adjusts the output of the
speakers based on placement, performance, and the room's acoustic
characteristics. Yamaha's YPAO system uses a small microphone and sophisticated
equalization to automatically set the best sound for any room, no matter where
the speakers are. First it checks the speaker connections and phase of each
speaker. Then it sends out tones which are captured by the microphone to analyze
the room acoustics and sets a variety of parameters; such as the speaker size,
the distance of the speakers, and even the volume level; until it achieves the
best sound conditions for your room.
- R.S.C. (Reflected Sound Control) Multipoint: The
receiver employs R.S.C. (Reflected Sound Control) to correct early
reflections for studio-quality surround sound. Up to 8 listening position
measurements are taken to optimize the surround effect for a broad area (you
can store up to two speaker patterns).
- EQ: 6Choose between 3 YPAO EQ modes -
Natural (adjusts all speakers to a natural sound; useful when the flat
setting sounds too bright), Flat (use when all the speakers in the system
have similar sound characteristics), or Front (EQs the center and rear
speakers to sound like the front; useful when your front speakers are better
than the others in the system)
- DSP Effect Normalization: In addition, the receiver's
YPAO Sound Optimization provides DSP Effect Normalization, which varies the
Cinema DSP parameters according to the reflected sounds in the room.
- YPAO Volume: Human ears have less sensitivity to high
and low frequencies, especially at lower volumes. YPAO Volume applies
loudness EQ correction to automatically adjust high and low frequency levels
as volume changes. Using the YPAO measurement results, EQ correction is
optimized to your system settings and listening environment.
Note: You can also choose to manually adjust the AV
receiver's speaker, crossover, & EQ settings.
Compatible Digital Audio Formats: The AV receiver supports
the following stereo & multichannel digital audio formats through its HDMI
jacks and optical/coax digital inputs.

Immersive Surround Sound: The Yamaha RX-A870 AV receiver
goes beyond regular surround with the latest immersive surround sound formats,
including Dolby Atmos & DTS:X.
- Dolby Atmos: The Yamaha AV receiver will enhance
properly designed systems with
Dolby Atmos where sound comes alive from all directions, including
overhead, to fill the home theater with astonishing clarity, power, detail
and depth. The RX-A870 has the processing power to run a more enveloping
5.1.2ch Dolby Atmos layout utilizing front-height, ceiling mounted, or Dolby
Atmos-enabled speakers (sold separately). A 5.1.2 speaker configuration is
based upon a traditional 5.1 speaker layout complemented by two Front
Height, Overhead, or Dolby Atmos-enabled speakers.
DTS:X is the next generation object-based, multi-dimensional audio
technology from DTS. Unbound from channels, DTS:X conveys the fluid movement
of sound to create an incredibly rich, realistic and immersive soundscape -
in front of, behind, beside and above the audience - more accurately than
ever before. DTS:X offers the ability to automatically adapt the audio to
the speaker layout that best fits your space.
Post Decoding Formats: The Yamaha AV receiver supports Dolby
Surround, Neural:X, and DTS Neo:6 (Music/Cinema) to enhance 2-channel and
multichannel decoding formats.
- Dolby Surround:
Dolby Surround offers an enhanced cinema experience to your 2ch and
multichannel movie soundtracks using your existing 5.1ch, 7.1ch or Dolby
Atmos speaker setup. Dolby Surround enhances audio definition by improving
the spatial dimension and overall audio definition of movie soundtracks. It
does this by using four distinct surround zones that provide greater control
over the exact placement of each detail in a movie sound track, so audio can
be matched more accurately to the video on screen; this means more depth and
greater realism for your movies. As a result, individual sounds are clearer
and more distinct. It also improves the surround sound experience across the
entire theater by widening the listening "sweet spot".
- Neural:X: DTS:X incorporates Neural:X, the latest
spatial remapping technology from DTS, which provides a fully immersive
output for all types of source content; this includes DTS bitstreams and
non-encoded (PCM) data. Neural:X delivers a thrilling sense of immersive
sound to your speaker layout regardless of the original source format.
- DTS Neo:6: DTS Neo:6 is an advanced matrix decoder that
takes any two-channel source (including television broadcasts, CDs and DVDs)
and expands it into five or six channels. It also provides separate,
optimized modes for stereo music materials and matrix surround motion
picture soundtracks. DTS Neo:6 brings you a more revealing sound from
ordinary stereo and a more expansive home cinema experience.
Cinema DSP 3D: The actually measured soundfield data in
recorded soundtracks contain the information of the height of the sound images.
Cinema DSP 3D mode achieves the reproduction of the accurate height of these
sound images so that it can create the accurate and intensive stereoscopic
soundfield in your listening room. Yamaha Cinema DSP 3D
lets you enjoy your movies and music even more in your home; regardless if you
are using 5.1 speaker setup, only have a two-channel speaker system, or
listening through headphones.
- Virtual Presence Speaker (VPS): With the power of
Cinema DSP 3D technology and the Virtual Presence Speaker (VPS) mode, the
receiver virtually reproduces the height of the 3D soundfield without
actually having front presence speakers. The Virtual Presence Speaker
function makes full use of center and surround speakers to create audible
information from where presence (height) speakers are normally installed.
- Virtual Surround Back Speaker (VSBS): This receiver
also features a Virtual Surround Back Speaker function. Even without using
surround back speakers, you can experience more natural, lifelike sound from
behind you without physical speakers being installed in the surround back
area of the listening environment.
- Virtual Cinema DSP: Virtual Cinema DSP is an algorithm
that allows you to enjoy DSP soundfield surround effects while using a
minimal two-speaker system. Virtual Cinema DSP lets you enjoy the effects of
Cinema DSP surround sound without using surround speakers (handy for use in
custom installations where some rooms don't have surround speakers). It can
be used with the front/center speakers or even with just the two front left
and right speakers. This unit will switch to virtual Cinema DSP mode
automatically when surround speakers are unavailable.
- Virtual Cinema Front: With Virtual Cinema Front, you
will enjoy virtual 5-channel surround sound with higher quality and
resolution by installing surround speakers at the front. You get more
flexibility to arrange your speakers inside the room, along with easy
enjoyment of high quality surround sound.
- Silent Cinema: Silent Cinema makes it possible to hear
large-scale surround sound through ordinary headphones. This is a variation
of Cinema DSP technology that Yamaha developed to let you listen in private
to movies and other multi-channel sources for hours without listening
Cinema DSP Soundfields: Conventional multichannel audio
reproduction systems base their sound on Dolby Digital and DTS decoding, using
matrix and steering technologies to create surround sound effects. Yamaha Cinema
DSP is much more advanced, actually creating richly realized independent
soundfields that envelop you in an unmatched surround sound experience. With
dialog, music and effects ideally located in these separate soundfields, you
will hear sound with accurate placement, smooth movement, exceptional clarity
and richness, and realistic presence. It will seem as if the walls of your room
have disappeared and you are in the middle of your own immense theater. The AV
receiver offers 17 Cinema DSP programs for movies, music, and games.
- Movie Soundfields: Standard, Spectacle, Sci-Fi, Adventure, Drama, Mono Movie,
Sports, Action Game, Role Playing Game
- Music Soundfields: Hall Munich, Hall in Vienna,
Chamber, Cellar Club, The Roxy Theater, The Bottom Line, Music Video, 7ch Stereo
Note: You can
change the receiver's Cinema DSP effect level (level of the soundfield
effect to be added). You can adjust the level of the soundfield effect
from -6 dB to +3 dB.
CINEMA DSP Parameters: You can adjust the following
parameters of the Cinema DSP modes.
- DSP Level: You can change the receiver's CINEMA DSP
effect level (level of the soundfield effect to be added). You can adjust
the level of the soundfield effect from -6 dB to +3 dB.
- Delay: Adjusts the delay between the direct sound and
the presence soundfield (1-99ms), surround soundfield (1-49ms), and surround
back soundfield (1-49ms).
- Room Size: Adjusts the broadening effect (0.1-2.0) of
the presence soundfield, surround soundfield, and the surround back sound
- Liveness: Adjusts the loss (0-10) of the presence
soundfield, surround back soundfield, and surround back soundfield.
- Reverb: Adjusts the delay time of the rear reverberant
sound (1.0-5.0s), the delay between the direct sound and rear reverberant
sound (0-250ms), and the volume of the reverberant sound (0-100%).
HiFi Sound Modes: The Yamaha RX-A870 offers two HiFi audio
modes which bypass the receiver's tone & DSP processing for higher sound quality
performance. These HiFi sound modes let you play back input sources without any
soundfield effect processing. When either of these modes are enabled, each
speaker produces its own channel audio signal (without soundfield processing).
When playing back 2-channel sources, such as a CD player, stereo sound is heard
from the front speakers. When playing back multichannel sources, the receiver
produces unprocessed multichannel surround sound.
- Straight: 2-channel stereo sources are output from only
the front left and right speakers, while multi-channel sources are decoded
straight into the appropriate channels without any additional tone or DSP
- Pure Direct: Turns off the surround and tone circuitry,
and dims the front-panel display, allowing sources to bypass the decoders
and DSP processors of this unit so you can enjoy pure hi-fi sound from
2-channel or multi-channel sources. During Pure Direct playback no sound is
output from the subwoofer.
Compressed Music Enhancer: Yamaha employs sophisticated
digital signal processing with exclusive algorithms to enable playback that
improves the performance of compressed music formats, including MP3, WMA, AAC, &
Bluetooth (SBC/AAC). The Yamaha receiver's Compressed Music Enhancer feature is even optimized for
Bluetooth wireless audio streaming. With the Compressed Music Enhancer, highs and especially lows are richer
and smoother, bringing music back to life to be as close to the original as
Dialogue Level & Lift: Dialogue Level Adjustment lets you control
the volume of the vocal sound, so you hear movie dialog and music vocals at the
ideal level for clear, comfortable listening. Dialogue Lift adjust the perceived
height of dialogue sounds. If the dialogue sounds as if it in coming from below
the TV screen, you can raise its perceived height by increasing this setting.
Dynamic Range Control: The Yamaha RX-A870 employs two
Dynamic Range Control functions.
- Adaptive DRC: Adaptive DRC automatically adjusts the
dynamic range of the sound according to the volume level. This ensures that
you hear clear dialog, vocals, and all sound effects at comfortable levels.
There is no need to adjust the volume level as you listen; everything from
whispers to big explosions will be heard clearly and comfortably at the same
volume setting. It also tones down loud TV commercials and is ideal for
low-volume, late-night listening when you do not want to disturb others.
- Dynamic Range: The amount of dynamic range compression applied
to bitstream signals is adjustable; Min/Auto is suitable for low volume listening,
Standard is typical for home use, and Max doesn't compress the dynamic range at all.
Bass Management: The Yamaha RX-A870 AV receiver provides
the following Bass Management settings.
- Bass & Treble: You can adjust the balance of the
high-frequency range (Treble) and low-frequency range (Bass) of sounds
output from the receiver' front left and right speakers to obtain a desired
tone. You can independently adjust the bass (50Hz) and treble (20kHz) from
-6dB to +6dB in 0.5 dB increments. The tone control of the speakers or
headphones can be set separately.
- Extra Bass: You can select whether to play front
channel low-frequencies through either the front speaker or the
subwoofer, or through both the subwoofer and front speakers. Use the Extra
Bass feature to amplify bass tones, not just in your main room but also on
systems in Zone 2. Even with compact or in-wall speakers which typically
lack bass, you'll hear all your sources with powerful bass sound.
- Subwoofer Trim: The Subwoofer Trim control enhances the
low frequencies by avoiding overlap with the front speaker output. This will
result in a cleaner, more focused sound stage while providing a seamless
frequency response. When subwoofer frequency overlap occurs in conventional
systems, the overall sound is "pushed" toward the subwoofer. Subwoofer Trim
takes care of this by separating the low subwoofer frequencies cleanly, thus
stabilizing the front stage while providing a well-balanced enhanced bass
- Zone 2 Volume Equalizer: Automatically adjusts bass and treble
balance to match the volume on systems in Zone 2. Enjoy movies and music
with a natural sound quality balance even at low volumes.
Volume Setup: The Yamaha RX-A870 allows you to customize the
receiver's volume levels.
- Volume Scale: You can choose to display the "Relative" volume scale
(-80 to +16dB) or an "Absolute" volume scale (0 to 97).
- Max Volume Adjustment: Use this feature to set the
receiver's maximum volume level. This feature is useful to avoid turning the
volume too loud by mistake. You can set the Max Volume from -30dB to +15dB
in 5dB steps, or to +16.5dB (full volume range is -80dB to +16.5 dB).
- Initial Volume Setting: Use this feature to set the
volume level when the power is turned on. You can choose between Off (same
as the volume when the unit was turned off), Mute, and -80dB to + 16.5dB
in increments of 0.5dB.
- Input Trim: Use this feature to adjust the volume
level of each input. This is useful to balance the level of each input to
avoid sudden changes in volume when switching between input sources. The
range is from -6dB to +6dB in 0.5dB increments.
Audio Outputs: The Yamaha RX-A870 AV receiver is fitted with
binding-post speaker terminals and 7.2ch RCA pre-outs, along with a front-panel
- Speaker Terminals: The receiver has binding post
terminals for all speaker outputs. The binding posts can accept bare wire,
pin connectors, and single banana plugs. These terminals are spaced too far
apart for dual banana plugs and a collar surrounding them prevents the use
of spade connectors. You can select 8 ohms or 6 ohms in the menu depending
on your speaker application. The amplifier supports 4- to 8-ohm Front
speakers, and 6- to 8-ohm Center and Surround speakers.
- 7.2ch Pre-Out: The AV receiver features 7.2-channel
pre-outs (Front L/R, Center, Surround L/R, Surround Back L/R, and Dual Subs)
for connection to external power amplifiers. The pre-outs are variable. The
dual sub outputs are wired in parallel and output the same signal (they are
- Headphone Jack: The Yamaha RX-A870 is equipped with a
front-panel 1/4" headphone jack for connecting a set of headphones, so you
can listen to your music privately. Connecting a set of headphones
automatically mutes the receiver's speaker outputs. Sound effects applied
during playback can also be heard through the headphones.
Phono Input: The Yamaha RX-A870 AV receiver features a
dedicated Phono (MM) input for connecting your turntable and listening to your
Front-Panel Aux Input: The RX-A870 features a front-panel
Aux input (3.5mm) for connecting your portable audio player with a headphone
HDMI 2.0a: The Yamaha RX-A870 AV receiver is fitted with
eight HDMI 2.0a inputs (7 rear/1 front) and two HDMI 2.0a outputs that support
the latest HDMI standards; such as 4K/60Hz, 4:4:4 color subsampling, HDR (High
Dynamic Range), & Wide Color Gamut (BT.2020). The receiver's HDMI 1-3 inputs and
both HDMI outputs also support HDCP 2.2 for full support of today's 4K content
from Ultra HD Blu-ray, online video services (like Amazon & Netflix), and future
TV broadcast services.
- 4K/60Hz: The RX-A870 supports up to 4K (3840x2160
@ 60 frames per second on all of its
HDMI inputs and output. It also supports a 480i, 480p,
720p, 1080i, or 1080p video signal.
- HDCP 2.2: Only the receiver's HDMI 1-3 inputs and both
HDMI outputs support HDCP 2.2, which fully complies with the latest
copyright protection standard for 4K video transmission.
- 4:4:4 Color Subsampling: The receiver also supports RGB, YCbCr
4:4:4, YCbCr 4:2:2, and YCbCr 4:2:0 color subsampling (@ 60Hz or 50Hz). With 4:4:4
color subsampling, luminance (brightness) and chroma (color) are sampled at
the same rate; resulting in an RGB color palette as big as the video
sampling rate for a video image with more colors, plus greater color
accuracy and detail.
- Wide Color Gamut (BT.2020): The BT.2020 color standard delivers a
much wider color gamut and represents about 75% of the total visual color
spectrum, while the current Rec. 709 color standard selected as the color
space for HDTVs and early generation 4K Ultra HDTVs covers only 35% of the
total visual color spectrum.
Note: Use a premium high-speed 18Gbps HDMI cable for the best
HDR (High Dynamic Range): The Yamaha RX-A870 support HDR
(high dynamic range) Video - including HDR 10, Dolby Vision, and Hybrid
Log-Gamma. HDR (High Dynamic Range Video) provides enhanced picture quality by
simultaneously enabling greater detail for both the dark and bright parts of an
image. HDR reproduces a greater dynamic range of luminosity or brightness
levels, creating greater contrast. This increased contrast reveals the subtle
nuances of the image, from detailed blacks and shadows to the brightest whites
and colors, plus greater depth.
- HDR 10: HDR 10 is an open standard and currently the
most popular HDR format on the market. It uses static metadata at the start of a movie to tell the receiver
and your TV that the video content is encoded using HDR.
- Hybrid-Log Gamma: HLG (Hybrid-Log Gamma) is primarily
designed for live video feed and over-the-air broadcasts. It uses no
pre-encoded metadata and is backwards compatible with SDR. HLG's native
compatibility allows much of today's existing SDR infrastructure to be
re-used for HDR in the future.
- Dolby Vision: Unlike HDR 10 which contains static
metadata and HLG which uses no metadata, Dolby Vision uses dynamic metadata
technology which sets individual color and brightness levels for each and
every scene. Dolby works directly with filmmakers at major Hollywood studios
to create superior HDR video masters of blockbuster movies.
Note: Dolby Vision and Hybrid Log-Gamma will be available via future
firmware update (no eta).
4K Video Upscaling: The Yamaha RX-A870 AV receiver will
upscale video signals from analog (480i only)-to-HDMI and HDMI-to-HDMI, up to
4K. This means a much better picture with HDTVs capable of 720p, 1080i, 1080p,
or 4K resolution. Only the receiver's main HDMI output is capable of video
upconversion & upscaling; the sub HDMI output does not support video
upconversion or upscaling.
Dual HDMI Outputs: The receiver's two HDMI outputs are parallel, so
the same HDMI audio/video signal is output through both and can be used
simultaneously (video is output at the resolution supported by both TVs).
Other HDMI Features: The Yamaha RX-A870 AV receiver's HDMI
connectivity also offers 3D video pass-through, ARC (Audio Return Channel), Deep
Color & x.v.Color support, as well as an auto LipSync function.
- 3D Ready: The Yamaha RX-A870 AV receiver supports 3D
video pass-through (720p/1080p only) from connected 3D-compatible Blu-ray, games and broadcast
devices to 3D-compatible HDTVs (all 3D components must be connected via
HDMI). Special eyewear will be required for viewing 3D content.
- ARC (Audio Return Channel): This feature of the
RX-A870's main HDMI monitor output allows audio to be sent from your
compatible HDTV to the receiver through the same HDMI cable already being
used to send audio and video to your HDTV. This eliminates the need for
extra cables connected to your television.
- Deep Color & x.v.Color Support: The AV receiver supports Deep
Color and x.v.Color content, which can display a larger color range than
standard-definition schemes. The result is a more lifelike, vibrant picture
- LipSync: This function adjusts the delay between audio
and video output. You can do this manually or have the receiver set the
LipSync function automatically. When connected to a TV via HDMI the receiver
automatically adjusts audio output timing (0-500ms) if the TV supports an
automatic LipSync function. You can also manually delay the sound output up
to 500ms to synchronize it with the video image.
- Standby Through Mode: When the RX-A870 is in standby
mode (power off), the Standby Through feature allows HDMI source signals to
pass through the receiver to the TV. The HDMI input can be changed using the
remote control. So, there's no need to turn on the AV receiver in order to
switch HDMI sources.
Analog Video Inputs: The RX-A870 AV receiver is outfitted
with one composite video and one component video input. Both the composite and
component video inputs only support 480i. These analog
video inputs are upscaled (up to 4k) and upconverted to HDMI out to your TV (the receiver has
no analog video outputs).
Background Audio/Video: The Background Video feature allows
you to watch a video source while listening to a different audio source. With
the RX-A870, you can select any video input (HDMI or analog) and listen to audio
from any of the receiver's audio sources (including AM/FM tuner, Aux input,
USB, Network, or Bluetooth).
