However, if you want to connect your turntable to a modern receiver, you may run into a problem: most receivers don’t have a built-in phono preamp.
A phono preamp is necessary to boost the low-level signal from your turntable to a line-level signal that your receiver can handle.
In this article, we’ll show you how to connect a phono preamp to your receiver so you can enjoy your vinyl collection with high-quality sound.
Whether you’re a seasoned audiophile or just starting out, this guide will help you get the most out of your turntable setup.
How To Connect A Phono Preamp To A Receiver
Step 1: Position Your Turntable and Receiver
The first step in connecting a phono preamp to your receiver is to position your turntable and receiver next to each other. This will make it easier to connect the cables between the two devices.
Consider placing your turntable and receiver on an entertainment cabinet or shelving system that can dampen vibrations and minimize shaking.
Step 2: Connect the RCA Cables
Next, connect the RCA cables from your turntable to the RCA jacks labeled “In” or “Input” on the phono preamp. Make sure you connect the red cable to the red jack and the white cable to the white jack.
Then, connect a separate pair of RCA cables from the RCA jacks labeled “Out” or “Output” on the phono preamp to the aux or CD input on your receiver. Again, make sure you connect the red cable to the red jack and the white cable to the white jack.
Note: Do not connect the phono preamp wires to the phono input on your receiver as it will cause the sound to be distorted.
Step 3: Connect Your Turntable’s Ground Wire
If your turntable has a ground wire, connect it to the grounding post on the phono preamp. This will help reduce any unwanted noise or hum in your audio signal.
Step 4: Power Up Your Phono Preamp
Connect your phono preamp to its power supply and turn it on. This will activate the preamp and allow it to boost the low-level signal from your turntable.
Step 5: Adjust Your Receiver’s Input Settings
Finally, adjust your receiver’s input settings so that it matches the input you used for connection. This will ensure that you can hear vinyl playing back from your turntable.
If your receiver has a built-in phono preamp, simply connect your turntable’s output cable to the phono input on your receiver. If not, follow these steps to connect a separate phono preamp between your turntable and receiver.
By following these simple steps, you can easily connect a phono preamp to your receiver and enjoy high-quality sound from your vinyl collection.
Understanding The Importance Of A Phono Preamp
A phono preamp is an essential component for any turntable setup. The signal produced by a record cartridge is very weak, much lower than the standard signal level produced by most other consumer Hi-Fi electronics. A nominal output level from a phono cartridge is 1 mV (0.001 V), while the Aux input on your stereo system requires a signal level of 100 mV (0.1V). To meet the required level, a typical phono preamp will boost your signal by 40 – 50 dB.
Moreover, records are cut with the bass frequencies reduced and the high frequencies boosted. This equalization helps to permit longer recording times by keeping groove dimensions small, while also increasing sound quality and decreasing record wear. A phono preamp acts to equalize the signal in an attempt to bring it back — as close as possible — to the frequency response of the master recording. The entire process is referred to as the RIAA (Recording Industry Association of America) equalization curve, which became the general industry standard during the 1950s.
Without a phono preamp, the low-level signal from your turntable would not be strong enough to be heard through your speakers or stereo system. Additionally, without RIAA equalization, your records would sound unbalanced and lack depth.
Therefore, a phono preamp is not just an added-on component that helps your system run smoothly; it actually shapes your turntable’s performance and ensures it is able to work with the rest of your system. Using an external phono preamp will provide the best shielding from interference and its own power supply, so it doesn’t have to share with an electrically noisy power transformer on a hifi amplifier. By investing in a high-quality phono preamp, you can enjoy the full potential of your vinyl collection and experience superior sound quality.
Choosing The Right Phono Preamp For Your Turntable And Receiver
When it comes to choosing the right phono preamp for your turntable and receiver, there are a few things to consider. The first thing to determine is whether your receiver has a built-in phono preamp or not. If it does not, or if you want to upgrade to a better preamp, then you will need to purchase a separate one.
The next thing to consider is the type of cartridge your turntable uses. Most turntables use either Moving Magnet (MM) or Moving Coil (MC) cartridges. MM cartridges are more common and less expensive, while MC cartridges are more specialized and tend to be more expensive.
Once you know what type of cartridge your turntable uses, you can look for a phono preamp that is compatible with that type of cartridge. Some preamps are compatible with both types, while others are designed specifically for one type or the other.
Another important factor to consider is the level of customization and control you want over your sound. Some phono preamps offer advanced features like adjustable gain, load, and capacitance settings, which can help fine-tune your sound to your liking. Other preamps may be more basic and straightforward.
Lastly, consider your budget when choosing a phono preamp. While some high-end models can cost thousands of dollars, there are also many affordable options available that still offer great sound quality.
Connecting Your Phono Preamp To Your Turntable
Connecting your phono preamp to your turntable is an important step in setting up your vinyl audio system. Start by plugging your turntable’s audio signal cable and ground wire into the phono preamp box.
Make sure to connect the red cable to the red jack and the white cable to the white jack on the phono preamp. Then, connect the other end of the RCA cables from the “Out” or “Output” jacks on the phono preamp to the aux or CD input on your receiver.
If your turntable has a ground wire, connect it to the grounding post on the phono preamp. This will help reduce any unwanted noise or hum in your audio signal.
Finally, power up your phono preamp by connecting it to its power supply and turning it on. This will activate the preamp and allow it to boost the low-level signal from your turntable.
It’s important to note that connecting a separate outboard phono preamp between your turntable and receiver will bypass the built-in phono-stage of your receiver. This is helpful if you have a moving coil cartridge that requires a dedicated external preamp for optimal performance.
By following these steps, you can easily connect your phono preamp to your turntable and enjoy high-quality sound from your vinyl collection.
Troubleshooting Common Issues With Phono Preamp Connections
Despite following the above steps, you may encounter some common issues with phono preamp connections. Here are some tips on how to troubleshoot these issues:
1. Power Supply Issues: One of the most common problems is connecting a DC power adapter instead of an AC power adapter. Make sure to use the correct power supply for your phono preamp. If you’re unsure, refer to the manufacturer’s instructions or check their website for a list of compatible adapters.
2. Shielded Signal Cables: Another common issue is not using shielded signal cables or forgetting to connect the ground between the turntable and the phono stage. This can result in unwanted noise or hum in your audio signal. Make sure to use shielded cables and connect the ground wire properly.
3. Buzzing or Whirring Sounds: If you hear buzzing or whirring sounds in your audio signal, it could be caused by short circuits or loose connections. Check all your connections on your turntable, including the cartridge, RCA cables, ground wire, and power supply cable. Tighten any loose connections and make sure everything is properly connected.
4. Motor Issues: If the buzzing sound only happens when the platter is spinning, it could be coming from the motor. Try turning the motor on and off to see if the sound changes. If it does, the problem is likely coming from the motor.
5. Grounding Issues: If you notice significant whirring in your audio signal, make sure that the ground cable is always connected to your phono preamp and your turntable. If it’s properly connected and you still hear whirring, it could be that the audio ground located in the phono cable is cut. In this case, you can use a Hum Block plug to directly connect your Hi-Fi system to the ground and fix this issue.
By following these troubleshooting tips, you can easily identify and fix common issues with phono preamp connections and enjoy high-quality sound from your vinyl collection.
