How is the sound quality? Le Super 4 Max65 Sound Effect Monitoring
Super TV Max65 is different from other brands of TVs. In addition to quality, it focuses on the effects of sound. We know that many high-quality sound sources require high-quality audio support, such as Dolby movies.
Dolby Area
Like Dolby movies, general TV audio is difficult to show. Ultimately, Dolby movies do not have the same high-quality sound effects. After watching the movie, users will see an ordinary movie. The experience is very bad. Max65 has seized this pain point. This time it is also full of strength, and we hope to combine high-quality quality and sound, trying to "color and sound."
Subwoofer + Smart Home Center
The good voice relied on the “brothers†of the subwoofer and the smart home center. According to the data obtained, six smart home center array speakers (super bass unit x2+ independent vocal bass unit x4) were used. The pre-class electronic frequency division technology can respond to 120Hz-20KHz dynamic frequency range, and has Dolby Digital Plus/DTS HD audio double decoding and Dolby Audio audio post-processing technology. The subwoofer uses a 5.25-inch long-stroke high-fidelity speaker unit equipped with a bass reinforcement technology to respond to the 40Hz-120Hz dynamic frequency range.
In the end is it good or bad? The center chose two more well-known tracks, one from the Eagles' Hotel California and the other from Guns Rose's Don't Cry.
Sound test
Talk about the feelings, the Eagles's classic track "Hotel California", which is a live recording in a simulated bar, the performance of this section of the sound field is very good, followed by a round of applause, the sound will not play out in the sound It is very abrupt. The bass is strong and clean, with both volume and texture. The mid-tone is mellow, solid and both speed and elasticity. The high-end is full of violence and it is firm and dense. The most memorable is the immersive immersion, which is like "listening" to the vibration of guitar strings and drums on the scene.
And "Don't Cry" as a classic bass repertoire, when the song has a faint buzz, and rock music can accurately reflect the low-frequency texture, from the head to shock Xiaobian. And the deep dive, the sense of volume, and the flexibility are also the kind of low-frequency feelings that people listen to for a long time. Anyone who has heard of this song knows that there are so many sounds in the song. Under the loud volume, the low frequency of the Max65 sound system makes it very perfect. In addition to the bass, the performance of the tenor is remarkable, and the most plausible is that the vocals are more prominent in the three frequencies, the sound vividly on the paper, and has a good sense of depth, the singer AXL Rose's vicissitudes and heavy sense performance Very good.
