This adapter is specifically designed to connect all the stereo and mono microphonones to recorders provided with XLR inputs.
The electronic design prevent noise coming from phantom power and from external interference sources. Two rotary selectors allow the indipendent setting of bias current for each channel.
The internal circuitis done to reduce power source and combined with a very low noise stabilizer gives a constant current to the Plug in Power microphone.
NO EXTERNAL POWER REQUIRED except for the phantom power coming from the recorder.
