LINEPAUDIO A962 fancier-level HiFi Vacuum Tube Power Headphone Amplifier PreAmp, made of Beijing classic quality 6J9-J vacuum tube, USB-PC supported ASIO sound effect software will give out more professional, full, open-stage, soft and smooth sound, especially applicable to voice, string music, light music, and classical music, the performance of different frequency points is so perfect! Fine at high frequency, strong at low frequency! Easily drive 16??-600 ?? headphone of any class, quiet background without any current background noise! Two sets of audio signal inputs, one is USB signal input (USB-PC), USB cable is connected to PC, plug and play without a drive, directly used as an upscale USB external sound card. The USB port can be also connected to any model of Android mobile phones with OTG function. The other is 3.5mm interface audio signal input and you can connect it to mobile phone, CD, lossless music player or other audio source devices. In case of simultaneous inputs of USB signal and 3.5mm interface signal, 3.5mm interface signal input is preferred.  \u003cbr\u003e2. LINEPAUDIO A962 has three sets of audio signals, simultaneously output to meet the interface of different devices (RCA\/3.5mm\/6.35mm), the output end will deliver to you a real HiFi experience, whether connected to your upscale headphone or speaker, or used as a timbre adjustable PreAmp to connect your digital power amplifier, multimedia speaker or various stereo devices, what a real PreAmp. Of course, if you want to try the timbre style of different tube amplifiers, this product can fully meet your requirement, compatible with E180F, 6688 and other tube models, you may exchange at will.  \u003cbr\u003e3. Many music fanciers are concerned about the background noise of vacuum tube headphone amplifier, but this product frees you from this concern, its performance in controlling background noise is extraordinary, the background is quiet after several tests and optimizations of the circuit design, without any current background noise, you will hear the purest, most natural, and most nostalgic sound. As to the testing of the current background noise: as it is known to all, the current background noise comes from two sources, one is the vacuum tube headphone amplifier, the other is the audio source or the audio cable (the audio cable makes it more likely to generate background noise), the correct procedure of testing the headphone amplifier is to disconnect the audio input cable, with power on, if the background of the headphone amplifier is quiet, it indicates that the headphone amplifier has a very high SNR. If unquiet, or this seriously affects you from listening music, it indicates that the headphone amplifier has a very low SNR.  \u003cbr\u003e4. Notes: An electronic interference device near the desktop may also affect the SNR. For example, if the vacuum tube power amplifier is placed near a wireless router or device, it may be interfered to some extent. Enclosed by an aluminum shell, miniaturized but exquisite, the front, rear panel is precisely processed by CNC machining center, you will get a terrific handle, the ultra-small volume will not occupy your desktop space too much.

For a powerful signal amplifier distributor, you may need to run several long lines between the TV audio line and a receiver on the other side of the room, providing high gain through any line level signal source, allowing longer cable lines to run, or requiring \"buffering\" to solve low volume problem. You can use it to add signal amplifiers between the line level signal source and the power amplifier, and the RCA jack matches almost all other product interfaces.\u003cbr\u003e3.

The product provides an independent 3.5mm stereo earphone jack which can drive a variety of high-impedance professional monitor earphones. Each channel can drive 16Ohm-600Ohm and provide 8 stereo channels for output. There are four independent volume knob adjustments to control the 8-channel for simultaneous level signal output, presenting the rich sound quality, well-balanced bass, clear high frequency, and no other signal popping phenomenon, and ensuring lossless and undistorted sound. It can provide +20dB high gain through any line level signal source, allowing running through longer cable lines or \"buffering\" to solve low volume problems. You can use the product to connect line level signal source and power amplifier as a volume controller. The RCA socket can match almost all other product interfaces. The product is powered by an AC AC9V transformer.  \u003cbr\u003e \u003cbr\u003eSpecification \u003cbr\u003e1. Input impedance: 100K Ohm \u003cbr\u003e2. Input level: +14 dBV \u003cbr\u003e3.
