normal stereo sound to surround sound, adjust the sound to the reproduced content, transmit 4K HDR video signal, and so on.<\/p>\n<p>The hero of today&#8217;s test, Sony HT-ZF9, can do all the same, plus a lot of interesting things: it has a network connection and &#8220;advanced&#8221;

the connection to the soundbar is automatic.<\/p>\n<figure class=\"image-caption\"><a class=\"_gallery resize-image\" href=\"https:\/\/www.stereoindex.com\/tech\/wp-content\/uploads\/2021\/04\/Sony-HTZF9-12.jpg\" data-fancybox=\"default\"><img decoding=\"async\" class=\"aligncenter\" src=\"https:\/\/www.stereoindex.com\/tech\/wp-content\/uploads\/2021\/04\/Sony-HTZF9-12.jpg\" alt=\"\" \/><\/a><figcaption><\/figcaption><\/figure>\n<h3><a name=\"n4\"><\/a>Connection and configuration<\/h3>\n<p>The Sony HT-ZF9 soundbar, as mentioned above, can be placed simply on a horizontal surface &#8211; an equipment rack, shelf, chest of drawers, and so on.\u00a0This, of course, is the simplest option, which will take a couple of minutes &#8211; you just have to turn on the power.\u00a0But most of the users prefer to hang the device on the wall under the TV.\u00a0Here it is a little more complicated, but also no problem: there is a template for marking for holes in the wall, the fasteners are reliable and convenient &#8230;<\/p>\n<p>The subwoofer connects to the main device automatically, it happens quickly and without interruptions &#8211; during the testing there were no problems.\u00a0If suddenly something went wrong, it is possible to forcibly start synchronization using a button on the back wall.\u00a0Due to the fact that the holes of the speaker and bass reflex are located on the front panel, the subwoofer can be placed close to the walls or interior elements &#8211; so there should not be any special difficulties in finding a place.\u00a0All that remains is to &#8220;reach&#8221; the outlet using a non-removable power cable.<\/p>\n<p>And, of course, you need to connect a sound source.\u00a0It is clearly worth considering HDMI as the main option &#8211; this is both convenient and provides the most opportunities: from broadcasting high-definition formats to controlling other devices via HDMI CEC.\u00a0One of the connectors supports an enhanced version of Audio Return Channel &#8211; eARC, which is also found on most TVs.\u00a0It&#8217;s worth starting with him.<\/p>\n<p>If the transmitting device does not support ARC, it makes sense to use one of the two &#8220;ordinary&#8221; inputs.\u00a0For example, they should be preferred when working with a PC video card.\u00a0The soundbar is defined as a sound device and becomes available in the corresponding menu.\u00a0Sony HT-ZF9 supports video pass-through transmission up to 4K of all the most &#8220;advanced&#8221; formats, including Dolby Vision, HDR10 and Hybrid Log Gamma &#8211; therefore, in parallel with it, you can connect any players, game consoles and other devices.<\/p>\n<p>If HDMI for some reason is not suitable, there are many other options.\u00a0You can use the optical S \/ PDIF input, or you can use an analog mini-jack (3.5 mm).\u00a0And there is also a function of playing music files from drives connected to the USB port on the rear panel.\u00a0Plus, of course, network streaming &#8211; we&#8217;ll talk about it in detail below.<\/p>\n<p>In the meantime, let&#8217;s discuss the connection via Bluetooth.\u00a0Not the most current version 4.2 is used, but energy efficiency in this case is not a determining factor, so there is no point in paying special attention to this.\u00a0But in addition to basic SBC and AAC, the proprietary LDAC codec is supported, which has slightly more features.\u00a0But aptX is not, which is not very surprising: in the presence of its own &#8220;advanced&#8221; codec, the manufacturer has no motivation to obtain Qualcomm certification.\u00a0The complete list of codecs and modes supported by them, as always in our tests, was obtained using the Bluetooth Tweaker utility.<\/p>\n<figure class=\"image-caption\"><a class=\"_gallery resize-image\" href=\"https:\/\/www.stereoindex.com\/tech\/wp-content\/uploads\/2021\/04\/codec.png\" data-fancybox=\"default\"><img decoding=\"async\" src=\"https:\/\/www.stereoindex.com\/tech\/wp-content\/uploads\/2021\/04\/codec.png\" alt=\"\" \/><\/a><figcaption><\/figcaption><\/figure>\n<p>A Bluetooth connection is a good way to quickly play some background music or podcast, but with the Sony HT-ZF9, it&#8217;s easier to use network streaming.\u00a0However, pairing via Bluetooth with some gadget still makes sense &#8211; it will help establish a network connection.\u00a0This can also be done through the on-screen menu, which we will look at below, but the method considered here is the simplest and fastest.<\/p>\n<p>The soundbar is controlled by the Sony |\u00a0Music Center, available for iOS and Android &#8211; you should start setting up your device by installing it, otherwise many of the most convenient functions will be unavailable.\u00a0We install, agree with the terms of use, give the necessary permissions &#8211; everything is as usual.<\/p>\n<h3>Management and operation<\/h3>\n<p>Above, we have already looked at the touchscreen control panel located on the top of the device.\u00a0It allows you to carry out basic actions, but nothing more &#8211; you still cannot do without a remote control and an application.\u00a0The remote control is compact, but quite convenient.\u00a0The volume key is made in the form of a separate round &#8220;swing&#8221;, which is easy to find by touch.\u00a0Focusing on it, it is easy to find the volume control keys for the rear speakers and the subwoofer, located on the sides.<\/p>\n<figure class=\"image-caption\"><figcaption><\/figcaption><\/figure>\n<p>The remote control is comfortable in the hand, the keys are pressed softly and with a well-felt click &#8211; it is quite comfortable to use.\u00a0In the center there is a &#8220;joystick&#8221; for operating the on-screen menu, which is available when the soundbar is connected to the TV.\u00a0Power is supplied using two AAA cells.\u00a0The cover for their installation and replacement can be easily removed, but at the same time it is held in its place quite reliably.<\/p>\n<figure class=\"image-caption\"><a class=\"_gallery resize-image\" href=\"https:\/\/www.stereoindex.com\/tech\/wp-content\/uploads\/2021\/04\/Sony-HTZF9-4.jpg\" data-fancybox=\"default\"><img decoding=\"async\" class=\"aligncenter\" src=\"https:\/\/www.stereoindex.com\/tech\/wp-content\/uploads\/2021\/04\/Sony-HTZF9-4.jpg\" alt=\"\" \/><\/a><figcaption><\/figcaption><\/figure>\n<p>We will not go into detail about the on-screen menu &#8211; the number of settings in it is quite large: you can change the surround sound characteristics, select the codec used for Bluetooth connection, adjust the network parameters, and so on.<\/p>\n<p>The device also supports interaction with Google Assistant, but it does not have its own microphone &#8211; you will have to organize control through the gadget on which the Sony |\u00a0Music Center.<\/p>\n<p>As we saw above, the Sony HT-ZF9 is a versatile device with an extensive list of functions and is suitable not only for soundtracks for movies, but also for listening to music or podcasts, for example.\u00a0In some cases, the TV may not be turned on at all.\u00a0Multiroom is also supported: you can combine soundbars into groups and combine them with other acoustics, and then start playing one track simultaneously in several zones or, for example, &#8220;transfer&#8221; playback from room to room after you.<\/p>\n<p>But all the same, the main function of the system is to sound films and television programs.\u00a0And the sound, which we will talk about in more detail, is adapted specifically for it.\u00a0Physically, the device is equipped with three speakers, plus one more in the subwoofer.\u00a0However, with the help of the Vertical Surround Engine technology, the sound is \u201ccompleted\u201d to the 7.1.2 format.\u00a0Accordingly, the latest Dolby Atmos and DTS: X formats are supported.\u00a0Once again, we note that none of these devices will ever be able to replace full-fledged acoustics, this is quite obvious.<\/p>\n<p>However, modern algorithms for &#8220;upgrading&#8221; sound are much more perfect than their predecessors, with whom we got acquainted 10 years ago, or even 15 years ago.\u00a0Therefore, they give quite interesting results.\u00a0You should not expect breathtaking &#8220;flights&#8221; of sound around you, but you can feel the volume, you can often accurately determine the position of the sound source &#8211; listening becomes definitely more interesting than when playing in &#8220;normal&#8221; mode.<\/p>\n<p>The built-in DSP allows you to select one of several sound field adjustment modes, each of which not only changes the built-in equalizer settings, but also adds a certain amount of reverb and compression.\u00a0The AutoSound mode automatically adjusts all parameters to the content being played, and it often does it very well &#8211;

probably, it is to this frequency that the bass reflex of the subwoofer is tuned.\u00a0Plus there is a peak around 60 Hz, which can be associated with the resonances of the case, as an option.<\/p>\n<figure class=\"image-caption\"><a class=\"_gallery resize-image\" href=\"https:\/\/www.stereoindex.com\/tech\/wp-content\/uploads\/2021\/04\/fr3.png\" data-fancybox=\"default\"><img decoding=\"async\" src=\"https:\/\/www.stereoindex.com\/tech\/wp-content\/uploads\/2021\/04\/fr3.png\" alt=\"\" \/><\/a><figcaption><\/figcaption><\/figure>\n<p>Naturally, with an increase in the volume of the subwoofer, the severity of this effect will also increase, so you should not get too carried away.\u00a0The \u201cwaterfall\u201d obtained at the maximum volume value demonstrates this well to us.<\/p>\n<figure class=\"image-caption\"><a class=\"_gallery resize-image\" href=\"https:\/\/www.stereoindex.com\/tech\/wp-content\/uploads\/2021\/04\/fr4.png\" data-fancybox=\"default\"><img decoding=\"async\" src=\"https:\/\/www.stereoindex.com\/tech\/wp-content\/uploads\/2021\/04\/fr4.png\" alt=\"\" \/><\/a><figcaption><\/figcaption><\/figure>\n<p>At the same time, the peculiarities of the bass sound of the Sony HT-ZF9 are due not only to the resonances of the bass reflex and the case.\u00a0If you look at the graphs of the subwoofer and the main unit, a &#8220;dip&#8221; in the region of about 100-200 Hz becomes obvious.\u00a0The subwoofer still sounds in this range, but not so effectively.\u00a0The soundbar is trying too, but it really starts at around 250Hz.\u00a0So it turns out that we have a solid &#8220;hump&#8221;

it only slightly raises the bass, but brings the high frequencies forward.\u00a0But due to the reverberation, it thoroughly adds volume.<\/p>\n<figure class=\"image-caption\"><a class=\"_gallery resize-image\" href=\"https:\/\/www.stereoindex.com\/tech\/wp-content\/uploads\/2021\/04\/fr6.png\" data-fancybox=\"default\"><img decoding=\"async\" src=\"https:\/\/www.stereoindex.com\/tech\/wp-content\/uploads\/2021\/04\/fr6.png\" alt=\"\" \/><\/a><figcaption><\/figcaption><\/figure>\n<p>The rest of the profiles are about the same story.\u00a0I was a little surprised by the &#8220;news&#8221;

its reaction to a sweep-tone can hardly be indicative and interesting.<\/p>\n<figure class=\"image-caption\"><figcaption><\/figcaption><\/figure>\n<p>But the &#8220;voice mode&#8221; works quite predictably &#8211; it highlights the mid-frequency range, and after it slightly emphasizes the high frequencies.\u00a0The night mode sharply removes low frequencies, plus adds compression.\u00a0Due to the fact that the difference between the quietest and loudest sounds inside the audio track is reduced, its &#8220;readability&#8221;
