Most turntables need a Bluetooth adapter to connect wirelessly to your computer

Turntables do not come with built-in Bluetooth—they output sound through a phono preamp or directly to powered speakers. To send that audio to your computer over Bluetooth, you need a Bluetooth transmitter, a small device that plugs into your turntable's audio output and broadcasts the signal wirelessly. Your computer then receives it the same way it would receive audio from a Bluetooth speaker or headphones.

This is different from connecting a turntable with a USB cable, which sends a digital signal directly to your computer. Bluetooth transmission converts the analog audio signal from your turntable into a wireless format, which works well for listening but is not ideal if you plan to record or edit the audio in software.

Key Takeaways

  • A Bluetooth transmitter plugs into your turntable's RCA audio outputs and broadcasts the sound to your computer wirelessly.
  • Your computer must have Bluetooth capability built in or you will need a USB Bluetooth adapter to receive the signal.
  • Pairing takes about two minutes: put the transmitter in pairing mode, then search for it in your computer's Bluetooth settings and select it.
  • Audio delay (latency) over Bluetooth is noticeable if you are watching video, so a wired USB connection is better for recording or syncing with video.

What you need before you start

Check that your turntable has RCA audio outputs—two cables (usually red and white) on the back. If your turntable only has a built-in speaker and no RCA jacks, Bluetooth transmission is not possible. Most turntables made in the last 20 years have them.

Verify that your computer has Bluetooth. On Windows, open Settings, go to Devices, and look for Bluetooth in the left menu. On Mac, click the Apple menu, select System Settings, then click Bluetooth. If you see "Bluetooth is off" or a toggle to turn it on, you have it. If Bluetooth does not appear at all, your computer does not have it built in, and you will need a USB Bluetooth adapter (about $15 to $30).

You will also need a Bluetooth audio transmitter rated for turntables. Look for models that accept RCA input and support the A2DP audio profile. Common options include the TaoTronics Bluetooth 5.0 transmitter, the Mpowerd Bluetooth transmitter, or the 1Mii Bluetooth transmitter. These typically cost $25 to $60 and plug directly into your turntable's RCA outputs.

Step-by-step connection process

Step 1: Plug the transmitter into your turntable. Locate the RCA audio outputs on the back of your turntable. They are usually labeled L (left, white) and R (right, red). Connect the corresponding RCA cables from the transmitter to these jacks. If your turntable has a ground wire (a thin wire with a small connector), leave it as is—it does not affect Bluetooth transmission.

Step 2: Power on the transmitter. Most Bluetooth transmitters plug into a USB power source or use batteries. Plug it in or insert batteries according to the manufacturer's instructions. Look for a power light or LED indicator. Some transmitters have a separate button to enter pairing mode; check the manual to see if you need to press it now or wait until your computer searches for it.

Step 3: Open Bluetooth settings on your computer. On Windows, go to Settings > Devices > Bluetooth & devices, then toggle Bluetooth on. On Mac, go to System Settings > Bluetooth. Leave this window open.

Step 4: Put the transmitter in pairing mode. Most transmitters enter pairing mode automatically when powered on, but some require you to hold a button for 3 to 5 seconds until the LED flashes (usually blue or red). Refer to your transmitter's manual for the exact method. The transmitter will stay in pairing mode for about 2 to 3 minutes.

Step 5: Search for the transmitter on your computer. In your Bluetooth settings, click "Add device" (Windows) or wait for the list to refresh (Mac). The transmitter should appear with a name like "TaoTronics Bluetooth Transmitter" or similar. Click it to pair.

Step 6: Confirm the pairing. Your computer may ask you to confirm a code or straightforward show "Connected" once pairing is complete. The transmitter's LED will usually change from flashing to solid, indicating a successful connection.

Testing the connection and adjusting audio levels

Play a record on your turntable. You should hear sound coming from your computer's speakers or headphones within a few seconds. If you hear nothing, check that your turntable's volume is turned up and that your computer's volume is not muted. Open your computer's volume mixer to confirm the Bluetooth device is selected as the audio output.

On Windows, right-click the volume icon in the system tray and select "Open Volume mixer." Look for the Bluetooth transmitter in the list and make sure it is not muted. On Mac, go to System Preferences > Sound > Output and select the Bluetooth device from the list.

If the sound is distorted or very quiet, lower the volume on your turntable slightly and raise the volume on your computer. Bluetooth audio can clip if the input signal is too hot. Most turntables have a volume knob or dial on the back near the RCA outputs; adjust it until the sound is clear.

Fixing common connection problems

The transmitter does not appear in your Bluetooth list. Make sure the transmitter is powered on and in pairing mode. Some transmitters require you to hold the pairing button longer than you think—try holding it for 10 seconds. If it still does not appear, restart both the transmitter and your computer's Bluetooth radio (toggle it off and back on in settings).

The connection drops or cuts out. Bluetooth has a range of about 30 feet, but walls and metal objects can reduce it. Move your computer closer to the transmitter or move the transmitter to a more central location. If the problem persists, check whether other wireless devices (like a microwave or Wi-Fi router) are interfering. Bluetooth operates on the 2.4 GHz frequency, which is crowded. Try moving the transmitter away from your router.

You hear a delay between the turntable and your computer. This is normal for Bluetooth and is called latency. It is usually 100 to 200 milliseconds, which you will notice if you are watching video or trying to sync the audio with something else. If this is a problem, use a USB cable connection instead of Bluetooth.

The sound is very quiet. Check the volume level on your turntable (the dial on the back), your computer's system volume, and the volume in any audio software you are using. If all are turned up and the sound is still low, your turntable may have a weak output. Some turntables require a phono preamp to boost the signal; if yours does not have one built in, you may need to add an external preamp between the turntable and the transmitter.

When to use USB instead of Bluetooth

Bluetooth is convenient for listening to records through your computer's speakers, but it has limits. The audio is compressed, and the delay makes it unsuitable for recording or editing. If you want to capture your turntable's audio into software like Audacity or a digital audio workstation, use a USB connection instead.

A USB turntable or a USB audio interface connected to your turntable will send uncompressed audio directly to your computer with no delay. This is the better choice if you plan to digitize your record collection or use your turntable as an input source for streaming or recording.

Frequently Asked Questions

Can I use any Bluetooth speaker as a transmitter?

No. Bluetooth speakers receive audio; they do not transmit it. You need a Bluetooth transmitter, which does the opposite. A transmitter takes audio from your turntable and sends it to your computer or speakers. They are different devices with different purposes.

Will Bluetooth damage my turntable or records?

No. A Bluetooth transmitter only receives the audio signal that your turntable is already outputting. It does not change how the turntable works or affect the records. The transmitter is purely a receiver and broadcaster of sound.

What if my computer does not have Bluetooth?

Buy a USB Bluetooth adapter (about $15 to $30). Plug it into a USB port on your computer, and your computer will recognize it as a Bluetooth device. Then follow the same pairing steps with your transmitter. The adapter acts as a Bluetooth receiver for your computer.

Can I connect multiple computers to the same transmitter?

Most Bluetooth transmitters can only connect to one device at a time. If you want to switch from your computer to a phone or tablet, you will need to unpair the first device and pair the new one. Some higher-end transmitters support multiple connections, but you can only play audio to one device at a time.

Is there a delay when I play music over Bluetooth?

Yes, typically 100 to 200 milliseconds. You will not notice this when just listening to music, but it becomes obvious if you are watching video or trying to sync the audio with something visual. For recording or video work, a wired USB connection is better.
