Understanding how to hook up a turntable to speakers boils down to two essential questions: do your speakers have their own amplifier, and where is your phono preamp? Powered speakers connect directly to a turntable using a built-in preamp. Passive speakers always need an amplifier in between. Bluetooth and Wi-Fi speakers also work, with a few basic rules.
The most common problem owners encounter when figuring out how to hook up a turntable to speakers – a turntable that plays almost silently – is usually due to one small switch. This guide, part of our turntable setup guides, covers all three setups and their fixes.
In short
- Powered speakers (they have a power cord) connect directly to a turntable with a built-in preamp switched to LINE.
- Passive speakers (no power cord, speaker terminals only) need an amplifier or receiver between the turntable and the speakers.
- Match the switches: turntable and speaker both on LINE, or both on PHONO. Mixed settings produce either a whisper or loud, muffled distortion.
- Very quiet sound usually means the turntable switch is set to PHONO: owners regularly fix it by switching it to LINE, often after bumping it while dusting.
- Wi-Fi speakers need a line-in and add a short delay: Sonos Era models use a USB-C line-in adapter, and at low volume some owners hear the stylus a split second before the speaker.
First: is your speaker powered or passive?
Powered (active) speakers have their own amplifier and power supply, so they have a power cord and usually a volume knob or remote control. Passive speakers only have spring clips or binding posts on the back and strictly require a separate amplifier. Powered speakers do not connect to an amplifier’s speaker terminals; if you have both a receiver and powered speakers, you only need one of them for the turntable.
Second: where is your phono preamp?
A turntable’s cartridge produces only a few millivolts, so the signal has to pass through exactly one phono preamp before any speaker or amp’s line input. Many budget turntables include a built-in preamp with a PHONO/LINE switch: LINE turns the preamp on, while PHONO bypasses it. Check the manual or the back of the deck instead of guessing; owners often assume their turntable doesn’t have a preamp when it does, or vice versa. There are exceptions: the AT-LP140XP, designed for DJ mixers, has no switch and only outputs at phono level.
The switch rule. The turntable’s switch determines what signal level comes out; a powered speaker’s PHONO/LINE switch determines what level it expects. They must match:
| Turntable switch | Speaker or amp input | Result |
|---|---|---|
| LINE | LINE / AUX | Works perfectly: the turntable’s preamp is used |
| PHONO | PHONO | Works perfectly: the speaker’s or amp’s preamp is used |
| PHONO | LINE / AUX | Clear but almost silent: no preamp |
| LINE | PHONO | Loud, muffled and distorted: two preamps |
| Speakers | Turntable preamp | Turntable switch | What you need |
|---|---|---|---|
| Powered, normal line input | Built in | LINE | Just the RCA/AUX cable |
| Powered, with PHONO input | Any | PHONO | RCA cable, plus ground wire if included |
| Powered, line input only | None | none | External phono preamp |
| Passive | Built in | LINE | Amplifier or receiver, speaker wire |
| Passive | None, or amp has PHONO | PHONO | Amplifier with PHONO input, or external preamp + amp |
| Bluetooth speaker | Bluetooth turntable | LINE | Pairing process only |
| Wi-Fi speaker with line-in | Built in, or external | LINE | Analog line-in cable or adapter |
Setup 1: powered speakers
This is the simplest and cheapest method for how to hook up a turntable to speakers. Our list of record players with speakers covers ready-made combinations.
- Set the turntable’s PHONO/LINE switch to LINE, and the speaker’s PHONO/LINE switch (if it has one) to LINE.
- Connect the turntable’s output to the speaker’s input. Turntables output on either RCA plugs or a 3.5 mm jack.
- Select the matching input on the speaker (often labelled AUX or LINE). Check that it has really switched.
- Start at low volume and slowly turn it up while a record plays.
If your powered speakers have a PHONO input, you can use that instead: set both the turntable and the speaker to PHONO, and connect the ground wire to the speaker’s ground terminal. The Klipsch The Three II is one example, with a phono preamp RCA input along with Bluetooth and a 3.5 mm input; our Klipsch The Three II review covers it.
Which preamp to use is worth an A/B test. Owners of several powered speakers with built-in phono inputs found them disappointing, describing the sound as hollow, and preferred the turntable’s own preamp connected to the speaker’s line input. With a long cable run to the speakers, there is also a technical reason to use the turntable’s preamp: a long phono-level cable adds capacitance to the cartridge’s load, whereas a line-level cable does not matter.
Watch out
Do not combine a turntable set to LINE with a speaker or amp PHONO input. Feeding a line-level signal into PHONO can distort the audio and damage equipment, because the signal is amplified twice. Some manuals warn that this voids the warranty.
Setup 2: passive speakers with an amplifier
Passive speakers require an amplifier or receiver to drive them. The traditional chain is the turntable to a stereo receiver with RCA cables, then the amplifier to the passive speakers with speaker wire.
- Connect the turntable to the amplifier: to its PHONO input with the turntable set to PHONO, or to any line input with the turntable set to LINE.
- Connect the ground wire to the amplifier’s GND terminal if you use its PHONO input.
- Run speaker wire from the amplifier’s speaker terminals to each speaker, red (+) to red, black (−) to black at both ends.
- Select the correct input and slowly raise the volume.
Mixing up red and black on one speaker throws it out of phase with the other, resulting in thin bass and a vague stereo image. If your amplifier doesn’t have a PHONO input and your turntable doesn’t have a built-in preamp, add an external one (our guide to the best phono preamp under $500 lists the options). If you use an external preamp, connect it to AUX, not to PHONO.
From our listening room
Why the switch matters, in numbers: A typical moving magnet cartridge like the Ortofon 2M Red is rated at just 5.5 mV. A consumer line input works around 0.316 V, approximately 57 times higher. A phono preamp’s typical 40 dB of gain multiplies the signal by 100, to approximately 0.55 V. If the preamp is skipped, the speakers barely whisper; if two are used, the second one severely overloads.
Setup 3: Bluetooth and Wi-Fi speakers
Another popular solution for how to hook up a turntable to speakers is wireless audio. Bluetooth turntables pair with a Bluetooth speaker just like a phone does, and must be set to LINE, because Bluetooth speakers rarely contain a phono preamp. Bluetooth compresses the signal and can add a small delay; when a speaker has a wired line-in, owners often prefer it. Our Sony PS-LX310BT review looks at one popular Bluetooth deck.
Wi-Fi speakers like Sonos take the turntable through a physical line-in, and the speaker then streams it to the rest of your system. These are the line-in options by model:
| Sonos product | How the turntable connects |
|---|---|
| Five, Play:5 | Line-in port, RCA to 3.5 mm cable |
| Era 100, Era 300, Move 2 | Sonos Line-In Adapter (USB-C) plus RCA to 3.5 mm cable |
| Amp, Connect:Amp, Port, Connect | RCA cable to the input labelled IN |
A phono preamp is only needed if the turntable doesn’t have one built in. One line-in speaker can then play the record in other rooms over Wi-Fi. Our Sonos Five review covers the speaker with the simplest connection.
What owners notice in practice. Sonos buffers line-in audio for multiroom playback, with a delay of at least 75 ms. Many owners never notice it; others do, at low volume, because they hear the stylus chattering in the groove a split second before the speaker. Closing the dust cover or putting the turntable in a cabinet resolves the issue.
Tip
Sonos can switch to the line-in automatically when you start a record (its Autoplay setting), so you don’t need the app every time. If playback starts late or drops out between sides, set the audio delay to the minimum, or turn off Autoplay and start the line-in from the app.
When there is no sound, or not enough
Even when you know how to hook up a turntable to speakers, minor things can go wrong.
| Symptom | Likely cause | Fix |
|---|---|---|
| Clear but very quiet | Turntable on PHONO into a line input | Turntable to LINE |
| Loud, muffled, distorted | Two preamps (LINE into PHONO, or external preamp into PHONO) | Match the switches; external preamp into AUX |
| Nothing from powered speakers | Speaker on the wrong input (often Bluetooth), or no power | Select the input again; check both power cables |
| Half volume after moving the deck | Stylus not fully seated, dirty headshell contacts | Reseat the stylus; clean the headshell pins |
| One speaker silent | Cable, speaker or channel fault | Swap speakers between the amp’s channels to find which |
| Hum | Ground wire missing, or too many grounds | Connect the ground wire; never remove a mains safety earth |
A turntable will always sound a little quieter than a phone or streaming source at the same volume setting; that’s normal.
Keep the turntable away from the speakers
Whatever the setup, do not place the turntable on top of or right next to a speaker, subwoofer or amplifier. The cartridge picks up physical vibrations, and the sound can feed back into a low drone at higher volume; a deck sitting on an amplifier can also pick up transformer noise. A separate, solid surface solves most cases.
How to hook up a turntable to speakers – Summary
To successfully master how to hook up a turntable to speakers, match the setup to your specific speakers. Powered speakers connect directly, with the turntable and speaker both set to LINE, or both to PHONO. Passive speakers require an amplifier and speaker wire. In all cases, the signal passes through exactly one phono preamp, and a very quiet turntable is almost always caused by a switch mistakenly set to PHONO.
How to hook up a turntable to speakers – FAQ
Can you hook a turntable directly to speakers?
Yes, to powered speakers, if the turntable has a built-in preamp set to LINE or the speakers have a phono input. Passive speakers require an amplifier in between.
Why is my turntable so quiet through my speakers?
The turntable is almost certainly set to PHONO while connected to a line input. Switch it to LINE, or set the speaker’s own switch to PHONO if it has a phono input.
Should I set my turntable and powered speakers to PHONO or LINE?
Set both to the same thing: either both to LINE to use the turntable’s preamp, or both to PHONO to use the speaker’s. Never plug LINE into PHONO.
Can I connect a record player to Bluetooth speakers?
Yes, if the turntable has Bluetooth. Set it to LINE and pair it like any other source. A wired connection offers better sound if the speaker has a line input.
Do I need a phono preamp for powered speakers?
Only if the turntable does not have a built-in preamp and the speakers do not have a phono input.
