Made in Italy by McMANTOM - Milano Hi-End RCA in-line passive subsonic filter.
This audio filter is a Hi-End quality product and must be connected to the RCA input of the audio amplifier.
It muffles frequencies of the audio band below 20Hz with a slope of 12dB per octave.
Low frequencies in the inaudible or infrasound range, if not blocked, cause pronounced movement that may damage the woofer and / or subwoofer.
Meanwhile, these frequencies unnecessarily engage the amplifiers, negatively affecting the dynamics and correct reproduction of the actually available audio frequencies.
This filter is usually providential and decisive.
This is to be used in professional and home audio systems, it is especially valued by lovers ... of black vinyl.
The filter should ideally be placed between the preamplifier or RIAA equalizer and the amplifier input, but it has been used over the years, on several occasions, directly at the RCA input of the audio amplifier with excellent results.
The RCA coaxial plug that contains the circuit is made with flawless care.
The central body, made of brass (turned, milled, threaded and gold plated) and the external ruby red coating in aluminum (turned, milled,threaded and anodized) form the container of the circuit.
This product is available with high pass cutoff frequency: 20Hz 12dB/octave.
