DX-925 hifi bile machine upgrade power amplifier fever tube Bluetooth audio
Product description
1: The product is a hybrid power amplifier with electronic tubes and transistors. Compared with pure tube power amplifier and transistor power amplifier, the tube+transistor hybrid power amplifier has the warm characteristics of pure tube power amplifier and retains the speed sense of transistor power amplifier. This design can combine the advantages of the two types of power amplifier. Many HIFI enthusiasts are very fond of the hybrid power amplifier.
2: Compared with the previous aluminum alloy wire drawing process, the upgraded 925 power amplifier uses the body sanding process, and the overall appearance is more high-end and three-dimensional.
3:5.0 Bluetooth high-fidelity wireless connection playback. APTX-HD (high quality),supporting 48KHz/24bit sampling frequency, makes Bluetooth stereo listening closer to the pure wireless sound effect of lossless CD-level sound quality, enabling you to listen to the smallest details of music, as well as the lifelike sound quality that is difficult to distinguish live sound.
4: The upgraded 925 amplifier has an independent headphone connector on the front of the panel. You can connect headphones in the dead of night or in noisy environments to listen to your own music moments.
5: USB2.0 version, no need to worry about compatibility. Support MP3/WMA/APE/FLAC/WAV and other lossless formats of music.
6: High and low pitch can be adjusted independently. My voice quality is my own choice. Both high and low can be adjusted according to my hobbies. It is very unique and controls my own music rhythm.
7: Compared with the previous version, the upgraded 925 amplifier has added two small electronic tubes, two big tubes 5Z4P (or 5U4C instead) and four small tubes 6N3 (or 6H3N/5670 instead). The overall charm is full, and the sound quality is more exquisite, beautiful and warm
8: The two VU meter pointers swing with the change of music, with full dynamic sense, and also show the good working state of the machine.
9: Optical fiber/coaxial digital interface. The application of digital interface maintains the stability of signal transmission, and the sound quality is pure and high fidelity. The rich interfaces enable the power amplifier to connect with a variety of different audio sources.
In addition, the bass output interface can be connected to the active subwoofer to increase the bass effect and make the whole sound source sound field more full and rich.
10: The design and technology of the transformer are very important. If there is any deficiency, it will affect the frequency transient response of the power amplifier. The dual-ring transformer adopted by the 925 power amplifier ensures that the power amplifier has enough power to match the speakers, and the power of 80W per channel is enough to match more than 95% of the speakers on the market.
