Understanding What a Preamp Does — and Whether You Still Need Powered Speakers
A common point of confusion for new vinyl listeners is figuring out what equipment they actually need. If your turntable already has a built-in preamp, you may wonder:
“Do I still need powered speakers?”
The short answer:
You don’t need powered speakers — but you do need some form of amplification.
Let’s break down what that means.
1. What a Preamp Does (and Doesn’t Do)
A phono preamp boosts your turntable’s weak signal (phono level) to line level, which is usable by other audio gear.
A preamp:
- ✓ Raises the cartridge output to line level
- ✓ Applies RIAA equalization
- ✗ Does not power speakers
Even with a built-in preamp, your turntable cannot directly drive passive speakers.
2. Powered vs. Passive Speakers Explained
Powered (Active) Speakers
- Have their own built-in amplifier
- Can connect directly to a turntable with a preamp
- Easiest plug-and-play setup
Passive Speakers
- Have no built-in amplifier
- Require an external amp or receiver to produce sound
- Cannot work with just a preamp alone
3. If Your Turntable Has a Built-in Preamp: What Are Your Options?
Option 1: Use Powered Speakers (Simplest Setup)
Turntable (LINE OUT) → Powered Speakers
This is the easiest and most common modern setup.
No external amplifier needed.
Option 2: Use Passive Speakers (You’ll Need an Amplifier)
Turntable (LINE OUT) → Amplifier → Passive Speakers
Even with a built-in preamp, passive speakers still require a power amp.
A preamp alone is not enough.
4. Do You Need Powered Speakers?
You only need powered speakers if you don’t want to buy a separate amplifier.
- If you choose powered speakers → You’re ready to go.
- If you choose passive speakers → You need an amplifier between them and your turntable.
Either option works — it’s really about the system you want to build.
5. Quick Comparison: Which Setup Is Best?
| Setup | Pros | Cons |
|---|---|---|
| Turntable + Powered Speakers | Simple, compact, affordable, minimal cables | Less upgrade flexibility |
| Turntable + Amp + Passive Speakers | Higher upgrade potential, better long-term sound quality | More expensive, more components |
Final Answer
A built-in preamp does not replace the need for amplification.
If you want the easiest setup, powered speakers are the way to go.
If you want a more traditional hi-fi system, go with passive speakers and an amplifier.
