"Audio signal coupling" all use KINGBOX transparent polar capacitors, sound more soft and natural, fast response, low distortion. DAC and CD modified preferred. Used SMT import original op amp NE5532, magnification 5 times (if there is a need to change the 10-times magnification), there is a strong push-stage efforts, the entire circuit board layout simple and rational elements.

Dual power supply: Dual 5V-20V (Recommended dual 12V)

Size: 28X28mm / 1.1"x1.1"

Small size easy to install, can be installed directly in the amplifier, so long pull wiring to reduce signal loss and interference.

The new upgraded version of the signal path resistance, low temperature drift with high-precision chip resistors KOA blue, regardless of the ambient temperature is below 0 degrees or 100 degrees or more, the parameter is still strong, aviation instrument-level performance spike color ring resistance.

Package Included
