Descriptions:
PCB Size: 103mm * 65mm * 1.6mm
Buffer tube can be seen as a pre-amp bile, but its magnification slightly smaller than 1, the gain is approximately equal to 0dB.
It can play a role in better impedance matching (increase input impedance and lower output impedance, better rear drive level)
Tube buffer can effectively filter out the remaining digital audio signal, so mellow warm, soft Naiting!
You can replace yourself with the following more common type of pipe tubes also experience different styles: 6N3,5670,6H3, and so on.
6N3-Buffer Amp Specifications:
Frequency Response FR: 10Hz-40KHz +/- 1dB
Total harmonic distortion THD:> 0.005%
Signal to noise ratio S / N: 95dB
Gain: ≈0dB
Operating voltage: AC12V / 1000MA
Weight: 100g
Another feature of this buffer is the supply requirements are very simple, requires only a single 12V / 10W transformer screen voltage, filament voltage all set. Followed by good audio input, and audio line output can work! !
