Zapco introduces the ASP-L2T signal noise eliminator. The ASP-L2T utilizes custom designed and custom wound high efficiency transformers and other high SQ components to remove the direct connection between the different reference ground systems and eliminate noise, without affecting the bass content of the signal and without adding distortion into the signal.
Signal to Noise is over 130dB, and THD+Noise is less than 0.1%. Signal level and impedance of the output are exactly the same as the input, and the frequency response of the ASP-L2T will even exceed the response of the input signal from the head unit. In fact the ASP-L2T can even be considered a "conditioner" to improve the signal from the head unit before it arrives at the amplifier. Maximum performance upgrades occur between 500mV and 1 Volt.
