ASP-L2 T
2-Ch. Line Noise Filter:

Features and Functions

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.
