Preamp, amplifier, and receiver are some of the common terms that you may stumble upon while building your own home theater. Preamp vs receiver, which one is best for you? In majority of cases, a receiver is best for you because some receivers have amplifier and preamp built-in into it.
The decision entirely depends on the user’s use case. If you are picky and want to alter settings, EQ, volume as per your taste, a preamp along with an amplifier might be good for you. Speakers that require too much power will produce better audio with a dedicated amplifier with a preamp.
Receivers are the ultimate solution if you don’t want several devices or if space is an issue for you. If you spend well on a high-end receiver, then you can rely on it for enhanced audio quality. receivers often come with room correction software, advanced features like Dolby Atmos or DTS support.
Preamp vs receiver: Major differences
|Acts as||Preamp||Has preamp and amp built-in|
|Device||Mostly to amplifiers||Several (speaker, TV, turntable, CD, DVD, etc)|
|Controls||Many||Several (more than preamp)|
|Price||Expensive (including an amp)||Less expensive|
- Connection: comparing preamp vs receiver, a preamp allows you to connect it to an amplifier and then to loudspeakers. Receivers are more versatile as it allows to connect several devices and output to multiple devices as well.
- Device: Preamp mostly connects only to an amplifier. It takes weak signals from media players, recording microphones, instruments or small preamp-free receivers. AV receivers allow wide range of devices to connect. Comparing preamp vs receiver, the preamp doesn’t permit connection to gaming consoles, TV, projectors, etc. Some receivers can also connect to Wi-Fi and Bluetooth.
- Settings: Preamp vs receiver, which has more controls? Receivers offer more functions and controls compared to preamp. Preamps have basic controls like: gain, the low and high pass filters, volume, impedance, loading controls, and etc. Receivers have source switches, volume, equalizers, track/file switches, bass, frequency range, etc.
- Cost: Preamplifiers are affordable and often costs less than the receiver. However, you can’t use the preamp alone, you need an amplifier so the overall cost increases although the preamp itself is cheap.
Preamp: What is it and why do you need one?
Preamp takes weak signal mostly from microphone then boosts them or make them ready so pass into amplifiers. These amplifiers will boost up the signal. These weak signals are prepared to be as line-level signal so that amplifiers can amplify them.
You can easily build a home theater without a preamp, then when and why do you need one? Preamp is needed in scenarios where the audio source signals are weak and can’t be given as input directly to an amplifier.
In specific cases like if you are involved in things like karaoke, recording/mixing studio. Another reason to use preamp is where you want to use a preamp with an amplifier instead of a receiver.
This is for audiophile grade users, who understand the details of each device in the system and want to tweak their setting to get the louder and cleaner sound. The preamp can’t be used without an amplifier. The reason to use a preamp with an amplifier is because it will improve audio quality.
Preamp make systems versatile where you can connect several speakers easily. In home theaters, receiver or amplifier is the common term rather than a preamp. The device is mostly used in recording systems.
While choosing a preamp, make sure the amp and preamp has similar power ratings. This is to eliminate any introduction of signal distortion. Comparing amplifier vs preamp, the preamp works with audio processing to minimize background noise.
Who needs a preamp?
As mentioned above, preamp is used along with amplifier in recording scenario. Other audio enthusiasts who want to tweak every settings and consider themselves professional with enough knowledge can easily include a preamp in their system.
Receiver: What is it and why do you need one?
In majority of cases, a receiver is an all-in-one solution in home theaters. Amplifiers are widely used as well. The reason for this is, even if you want to get a preamp, you can easily find in inside an integrated amplifier or in many receivers as shown in the diagram below. Receiver is all-in-one because you get both an amplifier and preamp in it.
Receiver can be considered as the brain of the home theater system. It is mostly needed if you have several devices to connect or have a 5.1 or 7.1 home theater system. You can connect speakers, subwoofers, TV as output devices to the receiver. A gaming console, CD player, DVD player may act as input. It will automatically switch between devices.
If you spend well and choose a famous brand like Denon, Marantz or Yamaha, the sound quality will be impressive. It also works as ‘main control’ so you can adjust volume or EQ settings from the receiver. The reason you need a receiver is that you have more than one input and automatically input switching is much easier.
Also, the receiver with an amplifier in it will boost up the signals easily. Having a single receiver instead of an amplifier and preamp will save you money. They have several things inside including: power amplifier, video/audio inputs and outputs, preamps, and signal processors.
Comparing preamp vs amplifier vs receiver, the amplifier only amplifies the input signal and send it to speakers. it can be of two types: power and integrated amps. You can also use an amp instead of a receiver.
Preamp vs receiver: Why do you need a preamp over receiver?
If receiver has both amplifier and preamp, then why do you need a preamp? A preamp has more impact on the sound quality than other devices. The preamp comes before an amplifier. So, the signal goes as input into the preamp which goes through signal processing.
Preamps along with amplifiers are better when there is a chance that you may use large power-seeking speakers. a dedicated amplifier will be able to handle them much better than a receiver.
Benefits of using receiver over preamp:
Preamps need to be with amplifiers which are called separates.
- Receiver is less costly than the separates.
- Receivers has all functions needed
- Supports multiple inputs
- Easily fits in racks or tight spaces
- Damage in any parts will lead to replacing the whole unit

How to match preamp with an amplifier?
Since you are going to match the preamp with the amplifier:
- make sure the preamp and amp has similar power level.
- Compare preamp volume control and output impedance with the amplifier.
- Compare the preamp and amp sensitivity
Receivers are quite flexible. In some units, you will see a preamp output where you can include an additional amplifier in case you think you have powerful speakers and need extra power. If there is a weak signal, then without a preamp, the amplifier will produce poor audio quality which will be noisy and distorted.
Preamps are ideal for you if you want to use it in recording world. Preamps are quite affordable and if you think your home theater has low-voltage signal then pairing it with a good quality amplifier will dramatically improve sound quality.
Receivers or amplifier can be used without any preamp. Receivers give you flexibility to connect several devices, both wired or wireless. A decent receiver will amplify sound as required. If you are new, you will need help to setup the receiver and in most cases user manuals will help.
This parting gift is to serve your concern regarding receiver and preamp. Let’s find out more!
