PT2037

DESCRIPTION The PT2037 is a multiple functions audio signal processor, very low distortion and low noise are obtained by the advanced CMOS fabricate technology. All of characteristics and functions are designed for the customer who needs high performance and better hearing experience. This device provides a lot of new features like soft-mute and zero-crossing mute to minimize the noises during the audio sources are switching. Further more, the device equipped differential audio inputs to improve the Common Mode Reject Ratio and it is very helpful to canceling ground loop hum noises in the car and audio dock system.
