Details：

Based on the famous MBL6010D preamplifier circuit. ​ ​Dual - Mono channel design, with no electrical connection between the left and right channels. ​ ​Fully DC coupled circuit. ​ ​Sound characteristics: high resolution, straight curves, good three frequency extension, ultra-low distortion, and ultra-low noise. ​ ​Use the Japanese ALPS27 remote potentiometer. The volume can be adjusted manually or remotely. ​ ​Use 2pcs 50W imported transformers. (One per channel) ​ ​Use 10pcs of brand new super operational amplifiers OPA828 and 2pcs of NE5534. ​ ​Equipped with comprehensive protection, it has the functions of delayed startup and instant shutdown, avoiding the impact of power on/off. ​ ​Use original Swiss Schuster power sockets and Schuster gold-plated fuses. ​ ​Use Single crystal copper signal wire and American ALPHA solder wire for welding. ​ ​Use CNC to process all aluminum chassis. ​ ​4-way input: 2sets of RCA single ended inputs and 2 set of XLR balanced inputs ​ ​4-way output: 2 set of RCA single ended output and 2 set of XLR balanced output (RCA and balance output simultaneously, capable of connecting two amplifiers simultaneously)

AUX input with buffering:

Make the sound very lively and increase the density of the sound. We recommend giving it a try; ​ ​The AUX input is designed with a buffer circuit, which mainly increases input resistance, reduces output resistance, improves circuit dynamics, reduces noise, and enhances circuit stability; ​ ​Some audio sources have excessively high output resistance and cannot be loaded, but buffering can also solve the problem; ​ ​Specific sound effects can be compared with unbuffered input.
