RCA Output on a Record Player: Phono vs Line Explained

What does RCA output mean on a record player?

An RCA output on a record player is the pair of standard analog audio jacks used to send sound from the turntable to another device, such as a receiver, integrated amplifier, powered speakers, or an external phono preamp. They’re usually color-coded: red for the right channel and white (or black) for the left channel. When you connect those two plugs to a matching RCA input, you’re carrying a stereo signal—one channel per connector.

How RCA output works on a turntable

Inside a turntable, the cartridge produces a very low-level signal. That signal must travel out of the player through the RCA cables and then get amplified to speaker level. Depending on the turntable, the RCA output can be one of two types:

PHONO-level output: The raw cartridge signal. This needs a phono preamp (either built into your receiver/amp via a “PHONO” input or provided by a standalone preamp) to boost the level and apply the correct RIAA equalization.
LINE-level output: A stronger signal that’s already been preamplified inside the turntable. This can plug into regular inputs labeled “AUX,” “LINE,” “CD,” or “TAPE IN” on amps/receivers, or directly into many powered speakers.

Why it matters when setting up your system

Using the wrong input is the most common reason a record player sounds extremely quiet, thin, or overly distorted. A PHONO output into a standard AUX/LINE input will be too quiet and lack proper tonal balance. A LINE output into a PHONO input will likely sound loud and harsh because it’s being amplified twice.

What to look for on the back of the record player

Many modern turntables include a small switch labeled “PHONO/LINE.” If it’s set to PHONO, connect to a PHONO input or an external phono preamp. If it’s set to LINE, connect to any standard RCA line input.

FAQ

Do I need a phono preamp if my turntable has RCA outputs?

Only if the RCA output is phono-level. If your turntable has a built-in preamp (often a PHONO/LINE switch), set it to LINE to connect to regular AUX/LINE inputs without a separate preamp.
