DescriptionEach channel uses two independent amplifying units to form a symmetrical output line, Single-ended and balanced output are at the same time ;
The front class consists of a single 4-way amplifier circuit, using two LM49720 dual op amp;
Have a separate pre-stage output, can be connected to active speakers or pure after the class;
The use of matrix relay volume, effective to ensure that 4-way volume unanimous;
Native full-balanced architecture, from input to volume control to before and after zoom, without any conversion, complete four-way architecture;
Technical Parameters:
The power amplifier circuit uses separate Class A lines, each channel 2 pairs of power tube, a total of 8 pairs of power tube;
The main filter uses Nikon nichicon audio capacitor KG gold tune
Equipped with third gear gain (high,middle,low), Support amp and line (XLR) output at the same time;
There are three inputs: RCA * 1, XLR * 2
The left and right channels each adopt a custom 50W audio ring transformer, completely independent of each other without interference;
All aluminum chassis, silver and black colors available;
