Turntables produce a very weak signal, which needs to be amplified before it can be played through speakers. This is because the phono cartridge, which converts the vibrations of the stylus in the record groove into an electrical signal, produces a very low voltage output.
Amplifiers boost the signal from the turntable to a level that can be played through speakers. Amplifiers also provide other features, such as tone controls, volume control, and multiple inputs for connecting other audio sources.
Modern turntables may have a built-in preamplifier, but this is not the same as an amplifier. A preamplifier simply boosts the signal from the phono cartridge to a line level signal. This allows you to connect the turntable to an amplifier or other audio device that has a line level input.
If your turntable does not have a built-in preamplifier, you will need to purchase a separate preamplifier. Preamplifiers are relatively inexpensive and can be found at most electronics stores.
Even if your turntable has a built-in preamplifier, you may still want to use a separate amplifier. This is because dedicated amplifiers typically offer better sound quality than built-in amplifiers.
Here are some of the benefits of using a separate amplifier with a turntable:
- Better sound quality: Dedicated amplifiers typically have better components and circuitry than built-in amplifiers, which results in better sound quality.
- More power: Dedicated amplifiers typically offer more power than built-in amplifiers, which allows you to drive larger speakers and play louder music.
- More features: Dedicated amplifiers often have more features than built-in amplifiers, such as tone controls, bass boost, and multiple inputs.
If you are serious about getting the best possible sound quality from your turntable, you should use a separate amplifier. However, if you are on a budget or simply don’t need the extra power or features, you can use the built-in amplifier in your turntable.
Here are some things to consider when choosing an amplifier for a turntable:
- Impedance: The impedance of the amplifier should match the impedance of the speakers. Most amplifiers have an impedance of 4Ω or 8Ω, so they will be compatible with most speakers.
- Power handling: The power handling of the amplifier should be greater than the power handling of the speakers. This will ensure that the amplifier can drive the speakers to a comfortable listening level without distortion.
- Inputs: Make sure that the amplifier has the necessary inputs for your turntable. Most amplifiers have a phono input for connecting a turntable.
- Features: Consider the features that are important to you, such as tone controls, bass boost, and multiple inputs.
Once you have chosen an amplifier, you will need to connect it to your turntable and speakers. This is a relatively simple process, but it is important to follow the instructions that come with your amplifier and speakers.
Once everything is connected, you can start enjoying your music!
