What does LP mean on amplifier?
LP or Low Pass means we’re only allowing lower frequencies to play through. So ideally you want your interior speakers playing what they’re best designed to play, about 60-80 hertz and up and we have our subs playing about 60-80 hertz and down. Setting the LPF for 50 Hz is the best complementary setting. This setting means all of the frequencies below 50 Hz are sent to the subwoofer, and frequencies at 100 Hz (one octave above) are fully attenuated. At one half octave above (75 Hz) the attenuation is approximately -12 dB.
What’s LP stand for?
What is an LP? An LP record, or Long Play, refers to a vinyl record format that typically contains a full album. In the digital music era, LP has come to be synonymous with a full length album, regardless of the medium. The LP (from long playing or long play) is an analog sound storage medium, specifically a phonograph record format characterized by: a speed of 331⁄3 rpm; a 12- or 10-inch (30- or 25-cm) diameter; use of the microgroove groove specification; and a vinyl (a copolymer of vinyl chloride acetate) composition disk.
