Vinyl records have made a comeback in recent years, and with that comes the need to understand the different types of connections available for turntables.
One of the biggest sources of confusion among new and seasoned vinyl enthusiasts is the difference between phono and line signals.
In this article, we’ll break down everything you need to know about these two types of connections, including their strengths and weaknesses, so you can make an informed decision on which one to use for your turntable setup.
Whether you’re a seasoned audiophile or just starting out, read on to learn more about phono and line signals.
Should I Use Phono Or Line
The answer to whether you should use phono or line for your turntable setup depends on a few factors.
Firstly, it’s important to understand the difference between the two. A phono signal is a weaker electrical signal that comes directly from the turntable cartridge. On the other hand, a line signal is an amplified version of the phono signal and has the same size/strength as a signal from other audio sources like CD players.
If you have an older turntable that requires its own external preamp stage to boost the weak audio output, then you’ll need to use the phono input. However, if you’re using a turntable with a built-in preamp or any other audio device that has been preamplified on its own terms, then the line input will be most useful.
It’s also important to consider what type of music you’ll be listening to. If you listen mostly to vinyl records, then it’s recommended that you leave the switch on the back of your turntable set at “phono.” This is because the bass frequencies of a phono signal are significantly reduced (RIAA equalized) while this is not the case for a line signal.
On the other hand, if you want to play music from your computer or other audio devices like CDs, iPods, MP3 players, etc., then you’ll need to use the line input. This is because these devices produce a line-level output that’s already been amplified.
Ultimately, whether you should use phono or line depends on your specific setup and preferences. If you’re unsure which one to use, it’s always best to consult your turntable’s manual or seek advice from an experienced audio technician.
Understanding The Basics: What Are Phono And Line Signals?
To understand whether to use phono or line for your turntable setup, it’s important to first understand the difference between the two signals. A phono signal is a weaker electrical signal that comes directly from the turntable cartridge, while a line signal is an amplified version of the phono signal and has the same size/strength as a signal from other audio sources like CD players.
The reason for this difference lies in the fact that phono inputs on hi-fi equipment are specifically designed to handle the low-level signal output from a turntable’s phono cartridge, while line (sometimes labeled aux) inputs are intended to handle higher-level signals that come from other audio sources such as a CD player or tape deck. The phono-level signal from your turntable requires additional amplification and equalization compared to line inputs to properly boost and shape the sound from a turntable’s phono cartridge, which has a much lower output level and a different frequency response compared with other audio sources.
If you have an older turntable that requires its own external preamp stage to boost the weak audio output, then you’ll need to use the phono input. However, if you’re using a turntable with a built-in preamp or any other audio device that has been preamplified on its own terms, then the line input will be most useful.
It’s important to note that if you listen mostly to vinyl records, then it’s recommended that you leave the switch on the back of your turntable set at “phono.” This is because the bass frequencies of a phono signal are significantly reduced (RIAA equalized) while this is not the case for a line signal. On the other hand, if you want to play music from your computer or other audio devices like CDs, iPods, MP3 players, etc., then you’ll need to use the line input. This is because these devices produce a line-level output that’s already been amplified.
The Importance Of Choosing The Right Connection For Your Turntable Setup
Choosing the right connection for your turntable setup is crucial to achieving high-quality sound. The type of connection you choose will depend on whether your turntable has a built-in preamp or not. If it does not, then you will need to use the phono input on your amplifier or receiver. This is because the phono signal is much weaker than other audio signals and needs to be amplified before it can be audible.
Using a line input with a turntable that does not have a built-in preamp will result in very low sound levels and poor sound quality. On the other hand, if your turntable has a built-in preamp, then you can use the line input on your amplifier or receiver. This will provide a stronger signal that does not need to be amplified again.
It’s also important to consider the type of music you’ll be listening to. If you mostly listen to vinyl records, then using the phono input is recommended. This is because the bass frequencies in a phono signal are significantly reduced, while this is not the case for a line signal.
However, if you want to play music from other audio devices like CDs, iPods, MP3 players, etc., then you’ll need to use the line input. This is because these devices produce a line-level output that’s already been amplified.
Advantages And Disadvantages Of Using Phono Signals
There are both advantages and disadvantages to using a phono signal for your turntable setup.
Advantages:
– Phono signals are specifically designed for vinyl records, meaning they are RIAA equalized and have reduced bass frequencies. This allows for a more accurate and balanced sound when playing records.
– Using a phono input can also help preserve the lifespan of your records by reducing wear and tear on the grooves.
Disadvantages:
– Phono signals are weaker than line signals, which means they require an external preamp to boost the audio output. This can add additional cost and complexity to your setup.
– If you accidentally use a phono input for a non-vinyl audio source, the signal will be too weak and may result in poor sound quality or damage to your speakers.
Advantages And Disadvantages Of Using Line Signals
Using a line signal for your turntable setup has its advantages and disadvantages. One of the main advantages of using a line signal is that it’s already amplified, so you don’t need an external preamp stage to boost the audio output. This can save you money and space in your setup.
Another advantage of using a line signal is that it’s not subject to the RIAA equalization curve, which reduces the bass frequencies of a phono signal. This means that you’ll get a more natural and unaltered sound from your audio source.
However, there are also some disadvantages to using a line signal. One of the main disadvantages is that it can produce a stronger signal than what your amplifier or speakers are designed for. This can lead to distortion, clipping, and even damage to your equipment if you’re not careful.
Another disadvantage of using a line signal is that it may not be suitable for playing vinyl records. Vinyl records are designed to be played with a phono signal, which has been equalized to compensate for the limitations of the medium. If you use a line signal to play vinyl records, you may experience a loss of bass frequencies and other sound quality issues.
How To Determine Which Connection Is Right For You
Determining which connection is right for you depends on a few factors. Firstly, check if your turntable has a built-in preamp. If it does, then you can use the line input on your amplifier or receiver. However, if your turntable does not have a built-in preamp, then you’ll need to use the phono input along with an external preamp to boost the signal.
Secondly, consider what type of music you’ll be listening to. If you mostly listen to vinyl records, then it’s recommended that you use the phono input. This is because the bass frequencies of a phono signal are significantly reduced and need to be RIAA equalized to reach the flat frequency curve of the line signal. On the other hand, if you want to play music from your computer or other audio devices like CDs, iPods, MP3 players, etc., then you’ll need to use the line input.
Finally, check your amplifier or receiver’s input labels and make sure you’re connecting to the correct input. Never connect a phono preamp to jacks labeled OUTPUT, SUBWOOFER, ZONE 2, MULT-CHANNEL INPUT, or PREOUT. If in doubt, consult your amplifier or receiver’s manual or seek advice from an experienced audio technician.
Tips For Optimizing Your Turntable Setup With Phono Or Line Connections.
If you’ve decided to use a turntable with a separate preamp, here are some tips to optimize your setup:
1. Upgrade your phono preamp: While most turntables come with a good phono cartridge pre-installed, a more advanced phono preamp can make a significant difference in sound quality. Look for one that offers adjustable settings to get the most out of your cartridge, and consider investing in one with vacuum tube technology for a warm, inviting sound.
2. Consider adding an external subsonic filter: Some preamps come with a built-in subsonic filter that eliminates low-frequency “rumble,” which can be distracting during playback.
3. Choose the right amplifier: When connecting your preamp to an amplifier, consider your budget and specific needs. You can use an A/V receiver, separate amplifier, or powered speakers with built-in amplifiers. If your A/V receiver has a built-in preamp, you can plug your turntable directly into it without needing a separate preamp.
4. Experiment with different phono preamps: Not all phono preamps are created equal, so it’s worth experimenting with different ones to find the one that works best for your setup. Consider trying out the Cambridge Audio Alva Duo for extended resolution and better dynamics over the phono input on your amplifier.
By following these tips, you can optimize your turntable setup with phono or line connections and enjoy high-quality sound from your vinyl collection.
