That will depend on what type of turntable you intend to use with the LG XBOOM 700W Main Unit and Speaker System Combo Set - Black, Model # CM4590. The CM4590 features an Auxiliary port (AUX 1) which is a line level input, it does not have a 'Phono' input. If your turntable is a USB turntable, it incorporates an RIAA phono preamp so it can be connected to the AUX 1 port on the CM4590. If your turntable is an older turntable that does not have a built-in RIAA phono preamp, you will need to connect a phono preamp between the turntable and the CM4590. Phono input is an input that can only be used to connect a turntable or a record player. A phono input in a receiver is different from all the other inputs in one important way. And that is that it routes the signal straight to an internal phono preamp. The built-in phono preamp then does two very important things to the music signal. First, the tiny signal from the turntable cartridge is boosted/amplified so that it becomes approximately the same size/strength as a signal coming from a CD player or a cassette player. This is called LINE-level. The amplitude (size) of the signal is increased by approximately 1000X. And secondly, the bass is significantly increased while the high tones (treble) is significantly reduced. When records are carved, the bass is reduced to save space on the record. And the preamp corrects this so that the music again has the right balance between bass and treble. This process is called RIAA equalization. If you connect a turntable without a built-in preamp to a LINE-level input (i.e the AUX 1 port), the music volume will be extremely low. You will barely hear the music even with the volume knob turned to max. And the music will have no bass as the signal won’t be RIAA corrected...^IFV
Sorry, there was a problem. Please try again later.Yes, there’s an auxiliary-in port. I hooked it up to my old Panasonic turntable, works fine.
