So grab your favorite record and let’s get started!
How To Connect A Phono Preamp
Before we dive into the steps, let’s first understand what a phono preamp does.
A phono preamp is a device that amplifies the “phono” signal produced by a turntable. This signal is much quieter than other audio signals, so it needs to be boosted to “line level” before it can be played through speakers or headphones.
Now, let’s move on to the steps for connecting a phono preamp:
Step 1: Determine if your turntable has a built-in preamp
The first step is to check if your turntable has a built-in preamp. If it does, you can skip to step 3.
Step 2: Get an external phono preamp
If your turntable doesn’t have a built-in preamp, you’ll need to get an external one. You can find standalone phono preamps at most audio equipment stores or online retailers.
Step 3: Connect the turntable to the phono preamp
Take the RCA cables that are attached to your turntable and plug them into the phono preamp’s input audio jacks. If your turntable has a grounding wire, connect that to your phono preamp as well.
Step 4: Connect the phono preamp to the amplifier
With another set of RCA cables, connect the phono preamp’s output to one of the amplifier’s inputs. Make sure you select an analog input on your amplifier.
Step 5: Power up and test
Finally, power up your turntable, phono preamp, and amplifier. Select the input on your amplifier that corresponds to the phono preamp. Put on your favorite record and enjoy!
What Is A Phono Preamp And Why Do You Need One?
A phono preamp, also known as a phono stage, is an essential component in a vinyl setup. Its primary function is to amplify the “phono” signal produced by a turntable to a level that can be played through speakers or headphones. This signal is much quieter than other audio signals, so it needs to be boosted to “line level” before it can be played through your sound system.
Without a phono preamp, the sound produced by your turntable would be very reedy, thin, and extremely quiet. Some turntables come with a built-in phono preamp, while others do not. If your turntable does not have a built-in preamp and your amplifier or receiver does not have an input labeled “phono,” then you will need to purchase an external phono preamp.
A phono preamp performs a process on a scale that no other component in the phono audio chain comes close to matching. It shapes your turntable’s performance and ensures it is able to work with the rest of your system. It is also sometimes known as a phono stage.
Types Of Phono Preamps: Built-In Vs. External
When it comes to phono preamps, there are two main types: built-in and external. Built-in phono preamps are integrated into turntables or audio receivers, while external preamps are standalone units that require their own power supply and must be connected to the turntable with RCA cables.
Both types of preamps do the same job – they amplify the quiet output of a phono cartridge to line level so that the audio receiver and amplifier can use the signal. However, external preamps generally have better build quality and electrical components compared to internal preamps. This is because a built-in preamp often needs to fit within a smaller space of another piece of equipment, such as a turntable. Phono preamps within turntables are usually an afterthought and used as a sales “add-on.”
External preamps are built to do one thing: be a preamp. That’s why a higher-end external preamp will have less noise and distortion, more gain, and overall better sound than a built-in one. Additionally, external preamps offer more flexibility in terms of customization and upgrading. You can choose a specific type of phono preamp that is designed to work with your cartridge type (moving magnetic or moving coil), or even switch between the two with some models.
On the other hand, built-in phono preamps are convenient for those who don’t want to deal with extra equipment and cables. They are also more affordable than external preamps, as they are often included as a standard feature in turntables or audio receivers.
Ultimately, the choice between built-in and external phono preamps depends on your budget and personal preferences. If you’re serious about vinyl playback and want the best possible sound quality, an external phono preamp is the way to go. But if you’re just starting out or on a tight budget, a built-in preamp may be sufficient for your needs.
Connecting An External Phono Preamp: Step-by-Step Guide
If your turntable doesn’t have a built-in preamp, you’ll need to connect an external one. Here’s a step-by-step guide to help you:
Step 1: Get an external phono preamp
You can find standalone phono preamps at most audio equipment stores or online retailers.
Step 2: Plug in the RCA cables
Take the RCA cables that are attached to your turntable and plug them into the phono preamp’s input audio jacks. If your turntable has a grounding wire, connect that to your phono preamp as well.
Step 3: Connect the phono preamp to the amplifier
With another set of RCA cables, connect the phono preamp’s output to one of the amplifier’s inputs. Make sure you select an analog input on your amplifier.
Step 4: Set up the cartridge
Set your preamp to the proper cartridge setting, either MM or MC. If you are new to vinyl, you are most likely using a MM (or moving magnet) cartridge and not an expensive MC (or Moving Coil) cartridge.
Step 5: Power up and test
Finally, power up your turntable, phono preamp, and amplifier. Select the input on your amplifier that corresponds to the phono preamp. Put on your favorite record and enjoy!

Troubleshooting Common Phono Preamp Issues
While connecting a phono preamp is a relatively straightforward process, some issues may arise that can affect the sound quality. Here are some common problems and how to troubleshoot them:
1. Power supply issues
The most common problem with phono preamps is connecting the wrong power supply. Make sure you’re using an AC power adapter, not a DC one. If you’re unsure which adapter to use, check the manufacturer’s website for a list of compatible adapters.
2. Signal cable issues
Using unshielded signal cables or forgetting to connect the ground wire between the turntable and the phono preamp can cause noise issues. This is especially common with vintage turntables, but it can happen with any model. Make sure you’re using shielded cables and that the ground wire is securely connected.
3. Turntable pitch control problems
If you’re experiencing pitch control problems, there could be several causes. A dirty potentiometer (fader), loose or frayed wiring, calibration issues, loose or worn belt, grounding issues, or component failure could all be culprits. Try cleaning the potentiometer or replacing the belt first. If those don’t work, seek the services of a professional repair person.
4. Distortion issues
If you’re hearing distortion at higher volumes, it could be that your speakers are vibrating your turntable. Try moving your speakers further away from your turntable or isolating your turntable from vibrations using an isolation platform.
5. Stylus damage
If you’re still experiencing severe distortion even after trying all the above troubleshooting steps, it could be that your stylus is damaged. Send a photo of your stylus to the manufacturer for assistance.
By following these troubleshooting tips, you can ensure that your phono preamp is properly connected and producing high-quality sound.
