YJ Audio Power Amplifier Board 2.0 Dual Channel NE5532 + TDA7294 with Tone 2x85W

Description:

Using original TDA7294 and NE5532.

Pre-stage input capacitance and coupling capacitance between the use of CBB top capacitor 2.2UF, electrolytic capacitors used in Taiwan brand signals the main loop , the main filter capacitor using the NOVER pitched audio-specific capacitance 2 × 10000UF, using domestic flat bridge rectifier 25A and above , to ensure strong support for a steady stream of power .
 
Resistor selection of rings metal resistance , the main circuit employs a precision of ± 1% metal film resistors rings , ensure the machine a good signal to noise ratio .
 
1.6mm thick sheet using double-sided PCB , 2.0 oz copper thickness , HASL whole process to ensure that the size of the current through the good performance . PCB class quality .
 
Pre- tuning of the design negative feedback tuning , can reduce crossover distortion, a better sense of hearing, adjust volume, respectively: treble, bass , total volume.
 
Selection of gold-plated hole IC Block , is not an ordinary IC seat , more durable.

The entire circuit board trace layout are very strict and reasonable, the overall PCB traces using a little grounding.

The amplifier board is stable and reliable output power ; beautiful mellow sound , open sound field . Dimensional sense of strong , powerful low-frequency sound calm , very good signal to noise ratio , wide dynamic range ; details clear, excellent transient response , playing all kinds of music were afloat in the family environment is very good playback performance .
