Audio GD HE9 LE

Built in regenerative power supply 
Uses three R-core transformers (In total 260W ) and more than 100,000uf audio grade NOVER capacitors are used to ensure ample and smooth power delivery. 
Separate class A PSUs power supply for regenerative drivers ,Left and Right channel audio signal amps .
Total applied 8 pcs exact matching 150W transistors ( In total 1200W )  as the output stages  for implement large class A output power .
Uses most Hi-end grade parts and exactly matched transistors, OCC wires.
Four-channel 100 steps digitally controlled relay-based volume control avoids channel imbalance and improves sound quality .
Supper Exponential Volume Characteristic,  easy match the volume with very high headphone / speaker without change the gain mode.
20DB gain can drive the low sensitivity headphone very well.
5 groups input:  RCA X2, XLR X2, ACSS X1
Preamp output :   XLR / RCA / ACSS
Headphone amp output:    4pins XLR X1 /  3pins XLR X2 / 6.3MM X1
Static storage mode control software for avoid disturb sound quality , the MCU output once control data and save in the perform parts ,then stop output data until users next operation.
