Speaking of innovation (CAEATIVE), I believe it is more familiar audio brand for the elderly. Before the author also started his family's "small stones", ZSW and other classic products. The best thing in summer is to eat ice cream at home and watch the movie. The TV in the home has been bought for several years. The 55 inch is not small, but the sound is very ordinary. Not long ago, he took advantage of his newly-paid salary to enter the innovative KATANA sound bar. Play games, watch movies, listen to music, and have "fallen." Let's talk about the edge:

The official price of this audio is 2499 yuan, but early this month, "Zhang Auntie" pushed the price of 2,000 yuan to find a piece, or quite favorable drops, but the current MS Jingdong is in the "no goods" state:

SO, make up another Tmall link, official outlet (currently in the appointment):

To mention Japan's katana ("Katana" is its Japanese pronunciation) is just as famous as its cherry blossoms, and it has also become one of the symbols of Japanese culture (known as the chrysanthemum and knife). Born out of the Japanese sword of the Tang knife, the blade of the knife is beautifully curved. Its blade is extremely sharp, and it is suitable for quickly picking up the knife. Of course, it also produces a large number of swords. Well, the popularity of so much knowledge, I want to express is that the reason why the innovation of their own game speakers named "Katana", mostly out of its "form."

When she first pulled out the box, she was shocked by the huge packaging it had. The front cover is particularly eye-catching and dreamy against the background of colorful aurora. The same color and tone, what they want to express may be rich sound effects and backlight effects. In addition, through the effect map can also be clearly known by the main body and subwoofer two parts. On the back of the box is detailed information on the product features, main features and interface presentations and other graphic information, mainly in English, a total of five languages ​​(English, German, French, Japanese, Chinese). Through the mixed Chinese, several characteristics of the speaker can be summarized, such as a 4 unit 1 subwoofer, support 16.8 million LED lights SHOW, with a variety of connection methods (such features will be detailed later). The left and right sides of the box are printed with their respective audio performance, specifications and contents. There is no one on this map. In short, after browsing through the box to draw a variety of information on the text, it's basically possible to control and characterize it.

Although the box body is large, only half of the space occupied by the opened box is occupied, and the remaining half is filled with a large number of foam boards and cartons. The purpose is to better protect the body from being exposed during transportation. damage. The contents are still quite numerous, one for the main audio and one for the subwoofer, two ledges (with the screws on the back of the main audio removed to stand on the living room wall together with the TV), two plug lines, and one power adapter , And to connect the PC with the MicroUSB port cable, but the 3.5MM dual-head audio cable and even the monitor with fiber optic cable is not standard, you need to buy.

It should be noted that the power supply is provided by a total of two, but the specifications are not the same, one of them is fine, 7A-125V, and the other is 6A-250V, which is applicable to 110V (such as Japan) and 220V respectively. (such as our country) use of different voltage specifications. Therefore, when plugging in the power supply, you must be careful not to make mistakes, otherwise the electrical parts will not be damaged or even burned out.

The main body of the speaker is 60*600*79 mm (weight 5 kg), and the subwoofer is 333*130*299 mm (weight 4 kg). The two add up to a total weight of 9 kg. Let’s talk about the general layout of the sound body. KATANA has four sound units. The body has four built-in units. Two up-bass units are located on both sides of the top of the fuselage (the two big round speakers). The other two high-offset tweeters are split at the right and left corners (plus five separate long-stroke subwoofers). The front of the fuselage is a digital display area, the bottom of the LED light effect area, and the top of the middle panel at the button control area, the back of the exclusive recess distribution of all interfaces. The main body, the whole pay for the fuselage was a long strip, the left and right ends were cut corners, combined with aluminum alloy shell, looks angular, Founder tough.

The included IR (infrared) remote control powers a button battery for easy replacement. From mute to volume adjustment, from upper and lower song switching, play/pause to one-button BASS, switch from LED lighting effect to each mode selection, all in one body, and all are independent keys, which is quite pleasant to use, but this remote control The device is too small. If it can be changed into a strip like a TV remote control, it will feel more comfortable.

The five metal keys in the middle are lined up in a row. They are the power, volume +-, SOURCET, and SBX keys. In the power button (also known as the Bluetooth pairing key), there are LED lights in a circle to show different states. Among them, the blue light is in the bluetooth mode, and the white light is on during work. Press and hold for more than 3 seconds to enter the pairing status (blue flash). Press the "SOURCE" key repeatedly to switch between the "COMPUTER"/USB (U Disk)/BT (Bluetooth)/OPTICRL (Optical Link TV)/RUii (Audio Link Player) modes. The SBX controls the subwoofer. KATANA has a total of three interactive modes. In addition to the direct operation of the panel, it can also be controlled remotely through infrared and mobile phone apps.

The metal net cover on the front of the fuselage: Remove the tweeters on both sides, and the middle “screen display area” can display the current operation (volume adjustment, song switching, etc.) and mode in English. In addition, it needs special introduction is its "triple power amplifier" design, each sound unit of the sound has an independent cavity, and there is a power amplifier controlled by a DSP (multi-core digital signal processor) alone, two of which focus on the drive Bass, the other two are the main treble effect.

Both the back and the bottom are made of black plastic material, but unlike the ordinary sound, the bottom is designed with a circle of 16.8 million color LED strips (officially known as the auroral lighting system), a total of 49. And comes with a variety of cool lighting effects, such as the marvelous marquees, colorful eye-catching aurora SHOW, and different monochrome breathing lights. Of course it also supports programming customization.

Public interface list: audio interface are concentrated in the left recess of the fuselage, on both sides of the grid cooling holes, the interface is still quite rich, followed by the power hole, SUB (subwoofer connection), MICIN (external microphone, K song party favorite), 3.5mm headphone jack (for earphones only), AUX IN (can be connected to notebooks, mobile phones/tablets, game controllers and other external devices), OPTICAL (fiber port, used to connect TV, but most of the old TV models There is no such port. At this time, it can be connected to the set-top box or Bluetooth via smart box.) USB FLASH DRIVE (USB plug, USB flash drive can directly play and store music, maximum support 128G, this is also a characteristic feature of innovative products), COMPUTER (As the name suggests, even the computer).

Let's look at the performance of the subwoofer. The appearance of the subwoofer is not different from the common one. However, after careful observation, the position of the guide hole and the sounding unit is changed. The guide hole is on the top of the front and the bass unit is Located in the center of the side (the advantage is to speed up the gas flow inside the box to increase bass output, so that the bass effect is more shocking). So be careful when placing it.

MDF box with inverted hole:

Audio support Bluetooth 4.2 version, support AAC, SBC decoding, and compatible with A2DP (wireless stereo Bluetooth), AVRCP (Bluetooth remote control) and other protocols. 24-bit 96kHz high-fidelity audio playback (USB) is possible. It can also be set via Sound Blaster Connect (this application also has a mobile APP, which supports both IOS and Android platforms). The first installation prompts for firmware upgrade. The interface UI is a consistent black minimalist style. Each functional module is intuitive and intuitive. Through it, you can adjust EQ sound effects, LED lighting effects programming, interesting sound changes, etc., and the playability is still quite high.

As a home-based audio-visual entertainment speaker, in the measured part I will experience through games, music, movies and other aspects. Because the author's home TV model is older, and there is no fiber port (only coaxial), only through the box Bluetooth connection. When the time value changes to 5, "Come back," it's just like taking advantage of the weekends to revisit the first few parts. The previous three-dimensional surround effect that TV can't get out loud can be displayed immediately after KATANA is turned on, whether it is in the movie "Qi Qikuo The card's gears were distorted, the sound of the bridge collapsed, the distant and near roars and crash sounds of the plane crashed, and the heavy blows from the fist to the meat during the fight, especially the exciting dinosaur battles at the 4 climaxes. The roar of his voice, biting and striking, can be said to sound in the ear, making the author feel as if he is in the battlefield of the movie. While watching this year's Olympic awards "The City of Philharmonic" (the author's favorite this year), his melodious piano solo, his passionate singing, the sing of his chorus, and the heart-shattering at the end. It can be said that under KATANA's "deduction", the true feelings of the hero and heroine were fully expressed.

7.1 virtual surround audio playback (fibre input 5.1 is digital) can be implemented on both the PC and USB ports. When inserted into a computer, it can double as a computer sound card. Let's talk about listening to music. In addition to playing games and watching movies, I believe that it is also the choice of most people to use the trivial time of leisure time to listen to music. Although the main game, but this sound is also very good for listening to songs. The low frequency is full and powerful, with quality and quantity, explosive power, rich details, and dive is also in place. Compared to the strong low-frequency, the mid-range is more peaceful and natural, with a strong sense of hierarchy, fresh and clean vocals, and full of power. The sound field is very wide, and even in the dining room alongside the living room, you can feel the reverberation of space. High frequency has a certain degree of ductility and resolving power, with a slight burr. But on the whole, it is full of charm and quite resistant to hearing. Faced with a variety of music types such as rock, jazz, pop, classical, light music and so on.

Finally, the next game experience, as a game sound, KATANA sound performance in the game since the attention of everyone, the author "recollection" of a CS, accompanied by the familiar GOGOGO! The sound of bullets piercing through the ears and the footsteps of enemies in the distance allowed KATANA to do a very good job of “listening to the sound”, moving randomly and razor-sharp. In the fighting game, not only the background sounds of people applauding, but also the impact sounds when the fists are struck together, as well as the consistent sound of drinking, and the percussive sound after being knocked down. The stimulating sensation comes from the ears. In the story-based RPG games (such as the author likes to play the double-sword series), the stream is flowing and the bird's song is pleasing. The dialogues between the characters and the interaction between the characters, as well as the excitement and sometimes radical BGM, make people thoroughly integrate into the game.

Finally, for the next summary: the price of 2499 yuan in the TV speaker is relatively high. However, it is worthwhile to play with a circle. Innovative materials for workmanship have always been good. Why does it matter? Interfaces and functions are quite rich. It is also good to plug in a USB flash drive or a mobile phone to listen to the music. The bar design can be set up on the wall as a TV speaker, or simply placed next to the computer display as a game speaker (plus RGB color, the night's "light pollution" that is just). However, there are regrets, such as access to television only the fiber port, HDMI is missing, with a long time will be slightly hot, that as big as the chassis of the subwoofer for home space is a bit of friends for a little space.

Advantages: 1. Strips, which can be hung on the TV wall, can be placed near a computer desk, and do not take up much space;

2, Yan value is good, workmanship is also meticulous, support for USB support playback, interface is more abundant, function is more complete;

3, with RGB lighting effects, regarded as the icing on the cake, the sound quality is also good, remote control for the sofa party can be described as welfare.

Disadvantages: 1, compared to the main body, subwoofer head is equivalent to a compact chassis, a bit of a place;

2, only the fiber port, the old TV can only access the set-top box, or smart box with Bluetooth, a slight inconvenience;

3, saying that a good mobile phone APP did not find a circle (no major markets), the official did not release;

4. The price is a matter of opinion, and it's even better if the individual feels lower.
