The resurgence of vinyl records has led to a renewed interest in turntables, and with it, a plethora of questions from music enthusiasts. One of the most common queries is whether turntables need amplifiers. In this article, we’ll delve into the world of turntables, amplifiers, and the relationship between them.
Understanding Turntables and Their Signal Output
A turntable is an electro-mechanical device that converts the physical vibrations of a record into an electrical signal. This signal is then sent to a device that amplifies and processes it, allowing us to hear the music. The signal output of a turntable is typically very low, usually in the range of 4-6 millivolts (mV). This low signal output is not strong enough to drive a pair of speakers directly, which is where an amplifier comes into play.
The Role of an Amplifier in a Turntable Setup
An amplifier is an electronic device that increases the amplitude of a signal. In the context of a turntable setup, an amplifier takes the low-level signal from the turntable and boosts it to a level that’s strong enough to drive a pair of speakers. The amplifier also provides additional features such as tone controls, volume adjustment, and input selection.
Types of Amplifiers Used with Turntables
There are several types of amplifiers that can be used with turntables, including:
- Integrated amplifiers: These are all-in-one amplifiers that combine a preamplifier and a power amplifier in a single unit.
- Pre-amplifiers: These are specialized amplifiers designed specifically for turntables. They provide a high-gain, low-noise amplification stage that’s optimized for the low-level signal output of a turntable.
- Power amplifiers: These are amplifiers that provide the final stage of amplification before the signal is sent to the speakers.
Do All Turntables Need Amplifiers?
Not all turntables need amplifiers. Some turntables have a built-in amplifier, known as a “phono amplifier” or “phono stage.” These turntables are designed to provide a stronger signal output that’s strong enough to drive a pair of speakers directly.
However, even if a turntable has a built-in amplifier, it’s often recommended to use an external amplifier for several reasons:
- Better sound quality: An external amplifier can provide a higher level of sound quality than a built-in amplifier.
- Increased flexibility: An external amplifier provides more flexibility in terms of tone controls, volume adjustment, and input selection.
- Reduced noise: An external amplifier can help reduce noise and hum that may be present in the built-in amplifier.
Turntables with Built-in Amplifiers: Pros and Cons
Turntables with built-in amplifiers are convenient and easy to use, but they also have some limitations. Here are some pros and cons to consider:
- Pros:
- Convenience: Turntables with built-in amplifiers are easy to set up and use.
- Space-saving: They take up less space than a separate turntable and amplifier.
- Cons:
- Limited sound quality: The built-in amplifier may not provide the same level of sound quality as an external amplifier.
- Limited flexibility: The built-in amplifier may not provide the same level of tone controls, volume adjustment, and input selection as an external amplifier.
How to Choose the Right Amplifier for Your Turntable
Choosing the right amplifier for your turntable can be a daunting task, but here are some factors to consider:
- Input sensitivity: Make sure the amplifier has an input sensitivity that matches the output level of your turntable.
- Gain structure: Look for an amplifier with a gain structure that’s optimized for the low-level signal output of a turntable.
- Noise floor: Look for an amplifier with a low noise floor to minimize hum and noise.
- Tone controls: Consider an amplifier with tone controls that allow you to adjust the bass, treble, and midrange to your liking.

Conclusion
In conclusion, turntables do need amplifiers to produce a strong enough signal to drive a pair of speakers. While some turntables have built-in amplifiers, it’s often recommended to use an external amplifier for better sound quality, increased flexibility, and reduced noise. When choosing an amplifier for your turntable, consider factors such as input sensitivity, gain structure, noise floor, and tone controls. With the right amplifier, you can unlock the full potential of your turntable and enjoy a rich, immersive listening experience.
Do all turntables require an amplifier to function?
Not all turntables require an amplifier to function. Some turntables have a built-in preamplifier or are designed to work directly with a receiver or amplifier that has a phono input. However, many turntables, especially those with a moving coil or moving magnet cartridge, do require an external amplifier to boost the signal to a level that is strong enough to drive a pair of speakers.
If you’re unsure whether your turntable needs an amplifier, check the user manual or manufacturer’s website for specifications. You can also look for a label on the back of the turntable that indicates whether it has a built-in preamplifier or requires an external one. If you’re still unsure, it’s always best to consult with a professional or contact the manufacturer’s customer support for guidance.
What is the difference between a preamplifier and a power amplifier?
A preamplifier, also known as a phono preamp, is a type of amplifier that is specifically designed to boost the low-level signal from a turntable’s cartridge to a level that is strong enough to drive a power amplifier or receiver. A power amplifier, on the other hand, is a type of amplifier that is designed to drive a pair of speakers and produce sound.
In other words, a preamplifier is used to boost the signal from the turntable, while a power amplifier is used to boost the signal to a level that is strong enough to drive the speakers. Some amplifiers have both preamplifier and power amplifier stages built-in, while others require separate components.
Can I use a regular amplifier with my turntable?
It’s possible to use a regular amplifier with your turntable, but it depends on the type of amplifier and the turntable’s specifications. If your amplifier has a phono input, you can connect your turntable directly to it. However, if your amplifier only has line-level inputs, you’ll need to use a separate preamplifier to boost the signal from the turntable.
It’s also important to note that some amplifiers may not be designed to handle the low-level signal from a turntable, so you may need to use a preamplifier even if your amplifier has a phono input. It’s always best to check the user manual or manufacturer’s website for specifications and recommendations.
How do I connect my turntable to an amplifier?
To connect your turntable to an amplifier, you’ll need to use an RCA cable to connect the turntable’s output to the amplifier’s input. If your turntable has a built-in preamplifier, you can connect it directly to the amplifier’s line-level input. If your turntable requires an external preamplifier, you’ll need to connect the turntable to the preamplifier, and then connect the preamplifier to the amplifier.
Make sure to match the RCA cables to the correct inputs and outputs, and adjust the volume and tone controls on the amplifier to optimize the sound quality. You may also need to adjust the gain settings on the preamplifier or amplifier to get the best sound.
What are the benefits of using a separate preamplifier with my turntable?
Using a separate preamplifier with your turntable can provide several benefits, including improved sound quality, increased flexibility, and better noise reduction. A separate preamplifier can provide a cleaner and more accurate signal boost, which can result in better sound quality and less distortion.
Additionally, a separate preamplifier can provide more flexibility in terms of adjusting the gain and tone settings to optimize the sound quality. Some preamplifiers also have built-in noise reduction features, such as hum reduction or equalization, which can help to improve the overall sound quality.
Can I use a USB turntable with an amplifier?
Yes, you can use a USB turntable with an amplifier, but it depends on the type of amplifier and the turntable’s specifications. If your amplifier has a USB input, you can connect your USB turntable directly to it. However, if your amplifier only has analog inputs, you’ll need to use a separate USB-to-analog converter to connect the turntable to the amplifier.
Some USB turntables also have a built-in analog output, which can be connected directly to an amplifier. In this case, you can use the turntable with an amplifier without the need for a separate USB-to-analog converter.
Do I need a special amplifier for a high-end turntable?
If you have a high-end turntable, you may need a special amplifier that is designed to handle the high-quality signal from the turntable. High-end turntables often require a high-quality amplifier that can provide a clean and accurate signal boost, as well as precise tone and gain controls.
Look for an amplifier that is specifically designed for high-end turntables, and has features such as high-quality analog circuitry, precise tone and gain controls, and low noise levels. You may also want to consider an amplifier that has a built-in phono preamplifier, as this can provide the best possible sound quality from your high-end turntable.
