Audiophile tube preamplifier for high-end audio equipment that combines vintage and information delivery. Its core is based on audiophile-grade electronic lamps and the consequence of playing an audio signal through excellent rendering of electronic lamp sounds and distortion-level applications. It is equipped with a multi-channel audio output and output interface that includes circuit controls that ensure data transmission. Users can apply to the parameters and characteristics of the audio system, using the adjustment function to achieve sound quality at the HiFi level. Perfect gift for newborn parents, newborn mother, newborn father, baby shower, birthday, Christmas, festival and so on. 【Excellent processing technology and sound limitation】: The SA-1000 preamplifier was launched with a full aluminum housing and built-in 6H3N audiophile-grade tubes, integrating a tube preamplifier and lossless connected audio into one device to achieve a low level of distortion that was restored to sound control. The circuit is an independent design, with output disconnecting line outputs, sound noise, and other issues to achieve detailed, real-world audio output effects. 【Comprehensive audio output and output configuration】: equipped with 4 sets of RCA audio interfaces, can have access to various audio source devices such as mobile phones, computers, players, CDs, etc., and is connected to audio devices such as amplifiers, switches, etc. through 2 sets of RCA audio output interfaces to realize independent switching and choice that each connection provides a HiFi sound quality level. 【Sound quality optimization delivery function】: Built-in 5532 amplifier chip with equipment and power and sound level adjustment function. It can be adjusted to the parameters of different audio devices to achieve the HiFi sound effect. The distribution includes module 5532, which is activated by various impedances available on the market, activated and gentle, automatic and powerful sounds, output to the ears. 【High-quality material and continuous length】: The SA-1000 has a stylish design that combines an aluminum alloy housing, a vintage lamp and VU table elements. This is a solution and easy to place on your desk. The use of gold-plated RCA Lotos sockets provides impedance and conductivity for transmission and longer ranges. 【Highly integrated and compatible with version】: As an audio control device,which combines the functions of a two-level HIFI preamplifier,lossless control of audio and audiophile licenses,SA-1000 is a component for building a stationary audio system HiFi,which does not provide only a rich interface 4 simultaneous input and 2 outputs,but it also ensures that the output is isolated from each other and does not interfere with each other. A version from whether it's home entertainment or a certified version may have requirements and requirements for system compliance and compliance.
