Preamp Tone Board 2.0 Preamp Stereo HIFI NE5532 Tone Board Preamplif

Detailed Information About The Product:

The Correction capacitor adopts imported Siemens the lower distortion effect is better the main filter capacitor adopts the imported capacity of 2x3300UF Use more than 3A and rectify continuous power to ensure strong support.
Choose the metal resistance rings the accuracy of +/- 1% rings the metal film resistance is used in the main circuit ensure the machine has good signal-to-noise ratio.
PCB used 1.6mm thick double-sided board 2.0oz thick copper tin the whole process to ensure good performance of current size.The first-rate PCB quality.
Using fully dustproof potentiometer the performance is more stable more durable than ordinary potentiometer.
Class aa parallel adjustment type regulated power supply the characteristics of high speed low noise low internal resistance.In noise music sense of detail and extension etc. are all series of regulated power supply can not achieve.

Tandem pressure switch no parallel with the dynamic load performance of good because the str ing when the conduction degree of the power light adjustment tube is low the approximate b so that the dynamic load accelerates from zero to 60 ma the power constant current source in parallel was a lot of current to adjust the tube Operating in a class for dynamic load from 30 ma to 90 ma the two reflect the speed must be different.
The whole circuit board walking line layout is quite precise rational overall printed circuit line by means of grounding to one point.The work is stable and reliable low frequency ence composed of a strong and strong signal-to-noise ratio the dynamic range is wide; Clear details transient response playing all kinds of music are to face bring the sound environment into family has very good performance.
This board with sound switch high and low sounds when switching to sound can be adjusted
