I none of your stereo gear have a phono preamp built-in, then you must use a separate phono preamp to play vinyl records. If there is a PHONO input on your amplifier, receiver or powered speakers, then there is a phono preamp inside. If there is no such with, then the turntable does not have a built-in preamp and will only output a PHONO signal.Īmplifiers, receivers and even powered speakers do sometimes have a built-in preamp as well. The preamp is enabled when the switch is set to LINE. If there is a switch on the back of the turntable that is labeled PHONO/LINE, then the turntable has a built-in preamp. To connect a turntable correctly, we must know if the turntable has a built-in preamp or not. Or with a receiver that has a preamp built in. Turntables without a built-in preamp must be used with a separate preamp. A turntable with a built-in preamp outputs a standard LINE signal, just as a CD player.īut not all turntables have a built-in preamp. Some turntables have a phono preamp built-in. The weak PHONO signal is converted to standard LINE signal by the all famous PHONO preamp.Ī PHONO preamp inputs a PHONO signal and outputs a LINE signal. So if we connect a PHONO signal from a turntable to a LINE signal input on a stereo receiver, the music will barely be hearable. The standard audio signal that is outputted by CD players and other kinds of music sources is called a LINE signal.Ī LINE signal from a CD player is typically 100 times bigger than the PHONO signal from a turntable. It is much weaker than a standard audio signal that is outputted by CD players and other kinds of audio sources. The PHONO signal is the tiny signal that is outputted by the turntable’s cartridge.
