Black Upgraded 5th X1 HiFi Class A Fully Balanced Preamplifier 5-Band Tuning Bluetooth5.2 Audio Power Amplifier

Black Upgraded 5th X1 HiFi Class A Fully Balanced Preamplifier 5-Band Tuning Bluetooth5.2 Audio Power Amplifier

Improvements:
- The fifth generation has undergone significant changes, with upgraded appearance and circuitry. It features a 5-stage tone design that can be adjusted: ultra-low, low, mid, high, and ultra-high frequencies. The adjustment effect is obvious, the distortion is low, the sound is clear, the hierarchy is distinct, and the sound density is high. Multiple styles of sound effects can be adjusted according to personal preferences, and the system compatibility is extremely strong.

Five Stage Adjustment Function:
- The first stage is 30Hz, mainly improving the ultra-low frequency.
- The second stage is 125Hz, mainly improving the bass and bass intensity.
- The third stage is 500Hz, mainly adjusts the midrange and vocal sounds.
- The fourth stage is 2KHz, mainly adjusts the mid-high and sweet sounds.
- The fifth stage is above 10KHz and mainly improving the high and ultra-high sounds.
- The tone can be raised or lowered, and can be adjusted according to your audio system and personal preferences to achieve better results.

Features:
- 5.2 Lossless transmission Bluetooth, easily achieves lossless results with the powerful detail restoration ability of the built-in ES9038 decoding chip.
- Supported formats: for LDAC, APTX HD, APTX ADAPTIVE, APTX, AAC, SBC.
- Compared to traditional tuning circuits that use operational amplifiers, this module has clean frequency division, distinct high, medium, and low frequencies, obvious tuning effects, low distortion, clear and layered sound, and high fidelity. The fifth generation X1 adopts a total of three tone modules for processing: ultra-high, high, medium, low, and ultra-low, making it easy to produce good sound.
- The X1 preamplifier supports balanced input and balanced output, with low distortion fully balanced output that effectively resists interference, making the sound purer and more transparent and rounded.
- Provide dual output interfaces, two sets of RCA, two sets of XLR, can be used simultaneously, connected to multiple amplifiers, to achieve channel splitting gameplay.
- Support remote control function, aluminum alloy remote control supports: power on/off, mute, audio source selection, volume control.
- The all aluminum refined chassis adopts for CMC technology, which is finely processed at the aviation aluminum level, elegant, high-end and atmospheric.
- The Green Magic sealed transformer has the advantages of vibration-free, noise-free, strong anti-interference, output characteristics, small ripple, high current, and pure power supply, which is the fundamental cornerstone of high-quality audio.
- The pure Class A positive and negative linear voltage regulator circuit, multi-stage independent rectification and filtering, and anti-interference circuit design are adopted. The advantages of the pure Class A voltage regulator power supply are: smooth and clean output characteristics like a battery greatly enhance the texture of music, resulting in clean sound and a background as quiet as the deep sea.

Materials:
- For ALPS motor remote potentiometer imported from Japan has good sound quality, precise positioning, and extremely low left-right balance error.
- Using for ELNA HiFi grade capacitors, the noise filtering efficiency reaches over 99.99%. The low frequency is sturdy and elastic, with full force and higher sound clarity. The mid frequency is smooth, sweet, and the high frequency is cleaner.
- Using 4 metalized polypropylene capacitors, it has outstanding features such as low internal resistance, low loss, and superior high-frequency characteristics.
- HiFi grade audio capacitor, with stable performance, long service life, excellent filtering performance, and good high-frequency characteristics, is commonly used in high-end HIFI speakers.
- For WIMA capacitor metal foil polypropylene has extremely low dielectric loss, high voltage resistance, high performance indicators, and is transparent and delicate.
- The use of a HiFi grade electronic tube operational amplifier has the characteristics of low distortion, low noise, low loss, and large signal bandwidth, bringing purer sound and better dynamic range to the whole machine.
