About The Product1. 6 port stereo speaker selector amplifier switch switcher 2. The speaker switcher allows the user to connect multiple pairs of speakers to a single stereo receiver or amplifier or vice versa to multiple amplifiers/receivers of a single speaker pair. 3. The device has a convenient button terminal that can accept up to 12 AWG speaker lines. 4. Note: this speaker switch does not allow multiple speaker pairs to be selected simultaneously. Only one pair of outputs can be selected at a time. 5. This speaker selection can also be used in the opposite way, imagine having multiple amplifiers connected to a speaker pair for setting. Because each stereo amplifier has its own sound characteristics, the user can connect different power amplifiers to the switch and then output to the same speaker pair. 6. Connect multiple speakers to an audio amplifier/receiver as loudspeakers to select a pair of speakers at a time. 7. Connect multiple amplifiers/receivers to a pair of speakers as an amplifier selection to select one amplifier/receiver. 8. The high-current amplifier protection circuit allows up to 6 pairs of speakers to be connected without damaging the amplifier. The protection circuit can safely protect unselected amplifiers or loudspeakers. 9. Select each time with a manual button on the front panel. Independent left/right channel grounding path, are compatible with all stereo amplifiers.Features1. Use convenient button terminal, can accept up to 12 AWG loudspeaker wires. 2.

About The Product1. 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. 2. 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.

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. 4. 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.
