Features
Power supply capacity of heavy material design: each channel is powered by a shielded toroidal transformer with a capacity of 300 watts of high power (maximum short-term power can reach 500 watts); 20000uF Dalian Wave Current imported ruby ​​electrolytic capacitors; 4 discrete ultra-low noise power supplies are designed for the small signal part of the circuit
Manually fine-tuned differential stages, combined with high-quality components such as precision resistors and imported film capacitors; the circuit is simple in design, but transistors with particularly excellent linearity are used where the audio signal passes.
With the same level of performance, we use a low open-loop gain design to achieve low transient intermodulation distortion and obtain low transient intermodulation distortion; excellent listening experience;
High and low gain adjustment 16/23db; Support high and low gain adjustment Single-End balanced switching, double input switching, no mutual interference
Advanced speaker protection function: overheating switch, overload, DC protection
1 – GND, 2 – Speaker Terminals, 3 – Power On/Off, 4 – RCA Single Ended input, 5 – XLR Balanced Input, 6 – Input selection switch, 7 – IEC Power Input & Fuse

Below extreme test, with 2 ohm load, the output can also be stable. (2 ohm load is not our recommended load, so this test only shows that it can work stable under 2 ohm load)
