Soundbar Speaker System: The Sony HT-ST9
High-Definition Soundbar Speaker System is a two-piece surround sound system
that brings simplicity and performance together by pairing a self-amplified
soundbar speaker and a wireless powered subwoofer to create and exceptional
audio experience marked by rich, natural, clear sound that complements your
high-definition or ultra high-definition flat-panel TV's incredible picture. The HT-ST9's soundbar system
will make any music or movie soundtrack come to life.
- Active Soundbar: The HT-ST9's soundbar speaker
incorporates ten drivers powered by seven discrete S-Master digital
amplifiers. The ten drivers are divided into front left, front right, and
center channels. The front left and right channels each consist of one
0.6875" tweeter and one 2.625" midrange driver which are coaxially mounted;
each channel powered by 75 watts. The center channel section of the soundbar
consists of one 0.6875" tweeter coaxially mounted to one 2.625" midrange
driver which are powered by 75 watts, plus four 2.625" full-range drivers
that are powered by 75 watts each. The soundbar can be wall-mounted
using the integrated key-hole slots on the back of the speaker, or simply
placed on a tabletop in front of your TV.
- Wireless Powered Sub: The HT-ST9 includes a wireless powered
subwoofer that compliments the soundbar for a seamless sound. The wireless
subwoofer houses a front-firing 7" woofer powered by a built-in
200W S-Master digital amplifier and a down-firing 7.875" x 11.8125" passive
radiator to deliver a powerful low bass notes. Because the powered subwoofer uses 5.8GHz wireless
technology, it can be placed virtually anywhere in your room (up to 33' from
soundbar). There are no extra
audio cables to run; you do have to plug the powered sub into an AC outlet.
Magnetic Fluid Speaker Technology: The Sony HT-ST9 employs Magnetic
Fluid Speaker technology. In conventional speakers, dampers provide suspension
and stability for voice coils, which unfortunately create unwanted noise and
distortion. By eliminating speaker dampers and replacing them with magnetic
fluid speaker technology, energy efficiency is dramatically improved, and mid
and high ranges are extended in incredible detail and clarity. With Magnetic
Fluid Speaker technology, the HT-ST9 allows a more accurate revealing sound, in
addition to cranking out 1.6x the volume of a conventional speaker.
S-Master Digital Amplifiers: Both the active soundbar
speaker and wireless powered subwoofer employ Sony's S-Master Digital
Amplifiers. Using a simplified, full digital signal path, the S-Master amplifier
reproduces digital audio signals without the multiple analog stages required by
conventional amplifiers. The result is not just more power, but significantly
less distortion caused by heat build-up.
S-Force Pro Front Surround: The HT-ST9 utilizes S-Force Pro
Front Surround to deliver virtual surround sound from a two-piece home theater
speaker system. S-Force PRO Front Surround mimics the way the brain correlates
sound sources to create proper volume, time lag, and sound wave spectrum - using
only left and right speaker channels. By naturally emulating three-dimensional
sound fields, you'll be able to enjoy rich, high-fidelity audio across a wider
Digital Surround Formats: The HT-ST9 supports the
following digital audio formats.
Note: Dolby Digital Plus, Dolby TrueHD, DTS-HD Master
Audio, DTS-HD High Resolution, and LPCM 7ch is only supported via HDMI.
Audio Settings: The HT-ST9 offers preset soundfields, dialog
enhancement, a night mode, an audio upscaler for compressed music files, and
dynamic range compression to add to your listening enjoyment.
- Soundfields w/ ClearAudio+: You can select from seven
different sound fields to optimize your surround sound experience. Choose from
ClearAudio+, Standard, Movie, Music, Music Arena, Game Studio, or Football.
Unique to Sony, ClearAudio+ automatically adjusts sound settings for an
enriching listening experience. By bringing together expertise in digital signal
processing technologies, ClearAudio+ is able to optimize audio formats to
deliver a consistently clear, high-quality sound, whatever music you're
- Voice & Night Modes: With Voice mode, you'll be sure to hear
every whisper and character nuance of the dialog compared to other sounds in the
scene for a dynamic experience. Using Night mode, you can enjoy sound effects
and hear the dialog clearly even at a low volume levels.
- DSEE HX: The Digital Sound Enhancement Engine HX (DSEE HX)
upscales your compressed digital music files (2ch 44.1/48kHz) and takes it
closer to the quality of High-Resolution Audio (up to 96kHz/24-bit equivalent).
By restoring the high-range sound lost in the compression process, DSEE HX
produces your digital music files in rich, natural sound, closer to the quality
of the original recording. This function does not work with DSD music files.
- Audio DRC: This feature allows you to compress
the dynamic range of Dolby Digital sound tracks.
- Subwoofer Level: You can increase or decrease the powered
subwoofer's volume level independent from the system's overall volume level.
ARC (Audio Return Channel): This feature allows audio
to be sent from your compatible HDTV to the HT-ST9 system 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.
Note: Because with most televisions, the ARC-enabled HDMI
input will only pass 2ch PCM from devices connected to the TV via HDMI or
analog, we recommend that you connect your Blu-ray/DVD player,
Satellite/Cable box, or Gaming console to the Sony HT-ST9 directly; and then
connect the HT-ST9's ARC-enabled HDMI output to your TV's ARC-enabled HDMI
input. This setup will give you with the best overall sound performance.
Digital + Analog Audio Inputs: The Sony HT-ST9 soundbar
system features both analog (minijack) audio and digital (optical) audio inputs
for connecting external audio sources such as your DVD player and CD player that
do not offer HDMI connectivity. There is single minijack (3.5mm) analog audio
input and one optical (toslink) digital audio input. The optical digital input
supports Dolby Digital, DTS, and 2ch PCM audio signals.
Note: The digital optical output terminals of most newer
flat-panel TVs only send an audio signal in 5.1ch when receiving Dolby
Digital/DTS surround sound from the TV's built-in tuner, network connection,
or connected USB device; and will output only 2ch stereo from sources
connected to the TV via HDMI, or RCA (like your Blue-ray/DVD player or
HDMI 2.0: The Sony HT-ST9 features three HDMI 2.0 inputs and
one HDMI 2.0 output which supports 4K pass-through, 1080/24p
video, x.v.Color, Deep Color, and 3D; as well as ARC and standby pass-through.
The system can detect and receive the best possible video and audio signals from
all connected devices via HDMI, making connection and performance as simple as
plugging in a single wire. Sony's HDMI Active Intelligence, transmits both audio
and video signals through one HDMI cable. The system's HDMI jacks
support 480i, 480p, 720p, 1080i, 1080p, and 4K.

to receive ultra high-definition resolution video and pass the video signal
to a 4K compatible TV or display monitor.
- HDCP 2.2: HDCP 2.2 is supported by the system's HDMI 1
input and HDMI ARC output. HDCP 2.2 is short for "High bandwidth Digital
Content Protection" and is used for 4K video copyright protection for
compatibility with 4K Blu-ray players and 4K Satellite/Cable providers.
- 4:4:4 Color Subsampling: The system's HDMI 2.0 jacks
support RGB, YCbCr 4:4:4 color subsampling for more vibrant and lifelike
images, as well as YCbCr 4:2:2 and YCbCr 4:2:0 color subsampling.
24p Output: The 24p Output settings allows you to watch
movies at their native frame rate 24p format (24 frames per second) when paired
with a 24p playback device like a Blu-ray Disc Player.
3D-Ready: The Sony HT-ST9 is compatible with 3D-ready
Blu-ray disc movies, video games and other 3D content through its HDMI
connection. 3D viewing requires 3D-ready source with 3D content,
3D-ready HDTV, 3D glasses, and high-speed HDMI cable. Other 3D accessories
may also be required.
Color Technologies: The Sony HT-ST9 incorporates Triluminos
Color, Deep Color, and x.v.Color technologies for perfect color and smooth
- Triluminos Color: The Sony soundbar speaker system
utilizes Sony's Triluminos Color technology to create a heightened sense of
depth and incredibly true, natural shades of colors. Hard-to-reproduce reds,
aqua blues and emerald greens are displayed beautifully, so landscapes and
seascapes look more vivid. Faces look better too, with natural skin tones.
- Deep Color: The soundbar speaker system also supports
Deep Color which allows the color depth of video signals passing through
HDMI to be raised. The number of colors that could be expressed by 1 pixel
was 24 bits (16,777,216 colors) with a standard HDMI jack. However, the
number of colors which can be expressed by 1 pixel is 36 bits with a Deep
Color enabled HDMI jack. Since the gradation of the depth of a color can be
expressed more finely with more bits, continuous color changes can be more
- x.v.Color: The Sony soundbar system supports x.v.Color,
offering a wider color range than the current broadcast standard. For the
x.v.Color feature to be useful, the entire video production chain must be
A/V Sync: The audio output can be delayed so that the time
gap between the audio output and the visual display is minimized. This is
especially helpful when you are using a large LCD or plasma TV or a projection
TV. When activated, the delay can be adjusted from 0-300 ms or set to Auto.
Standby Pass-Through: You can conveniently access all
your HDMI connected devices without having to power on the HT-ST9 system.
