When it comes to amplifiers, there are many features and functions that can be confusing, especially for those who are new to the world of audio equipment. One such feature is the “Pre Out” or “Preamp Out” on an amplifier. In this article, we will delve into the world of Pre Out, exploring what it is, how it works, and why it’s an essential feature for any serious audiophile or musician.
What is Pre Out on an Amplifier?
The Pre Out on an amplifier is a feature that allows you to send the preamplified audio signal to another device, such as a power amplifier, a recording device, or a effects processor. The preamplified signal is the audio signal that has been boosted by the preamp stage of the amplifier, but has not yet been amplified by the power amp stage.
In other words, the Pre Out sends the clean, unamplified audio signal to another device, allowing you to use the amplifier as a preamp only. This feature is useful in a variety of situations, such as when you want to use a separate power amplifier to drive your speakers, or when you want to record the audio signal directly from the preamp stage.
How Does Pre Out Work?
The Pre Out on an amplifier works by tapping into the preamp stage of the amplifier and sending the preamplified signal to an external device. The preamp stage is responsible for boosting the low-level audio signal from the source device, such as a guitar or microphone, to a level that is strong enough to drive the power amp stage.
When you use the Pre Out, you are essentially bypassing the power amp stage of the amplifier and sending the preamplified signal directly to another device. This allows you to use the amplifier as a preamp only, and to use a separate power amplifier to drive your speakers.
Types of Pre Out Connections
There are several types of Pre Out connections that you may find on an amplifier, including:
- RCA Pre Out: This type of connection uses RCA connectors to send the preamplified signal to another device.
- XLR Pre Out: This type of connection uses XLR connectors to send the preamplified signal to another device.
- 1/4″ Pre Out: This type of connection uses 1/4″ phone connectors to send the preamplified signal to another device.
Why Use Pre Out on an Amplifier?
There are several reasons why you might want to use the Pre Out on an amplifier, including:
- Flexibility: The Pre Out allows you to use the amplifier as a preamp only, and to use a separate power amplifier to drive your speakers. This gives you more flexibility in terms of the equipment you can use and the sound you can achieve.
- Improved Sound Quality: By using a separate power amplifier, you can improve the sound quality of your system. This is because the power amplifier can be optimized for the specific speakers you are using, resulting in a more accurate and detailed sound.
- Increased Headroom: The Pre Out allows you to send the preamplified signal to a separate power amplifier, which can provide more headroom and a cleaner sound.
Using Pre Out with a Separate Power Amplifier
One of the most common uses of the Pre Out is to send the preamplified signal to a separate power amplifier. This allows you to use the amplifier as a preamp only, and to use a separate power amplifier to drive your speakers.
To use the Pre Out with a separate power amplifier, you will need to connect the Pre Out of the amplifier to the input of the power amplifier. You will also need to connect the output of the power amplifier to your speakers.

Benefits of Using a Separate Power Amplifier
There are several benefits to using a separate power amplifier with the Pre Out, including:
- Improved Sound Quality: A separate power amplifier can provide a cleaner and more accurate sound, as it is optimized for the specific speakers you are using.
- Increased Headroom: A separate power amplifier can provide more headroom, resulting in a more dynamic and detailed sound.
- Greater Flexibility: A separate power amplifier gives you more flexibility in terms of the equipment you can use and the sound you can achieve.
Using Pre Out with a Recording Device
Another common use of the Pre Out is to send the preamplified signal to a recording device, such as a digital audio workstation (DAW) or a portable recorder.
To use the Pre Out with a recording device, you will need to connect the Pre Out of the amplifier to the input of the recording device. You can then record the audio signal directly from the preamp stage of the amplifier.
Benefits of Using Pre Out with a Recording Device
There are several benefits to using the Pre Out with a recording device, including:
- Improved Sound Quality: By recording the audio signal directly from the preamp stage, you can capture a cleaner and more accurate sound.
- Increased Flexibility: The Pre Out allows you to use the amplifier as a preamp only, and to use a separate recording device to capture the audio signal.
- Greater Control: By recording the audio signal directly from the preamp stage, you have more control over the sound and can make adjustments as needed.
Using Pre Out with Effects Processors
The Pre Out can also be used to send the preamplified signal to an effects processor, such as a reverb or delay unit.
To use the Pre Out with an effects processor, you will need to connect the Pre Out of the amplifier to the input of the effects processor. You can then use the effects processor to add effects to the audio signal.
Conclusion
In conclusion, the Pre Out on an amplifier is a powerful feature that allows you to send the preamplified audio signal to another device, such as a power amplifier, a recording device, or an effects processor. By using the Pre Out, you can improve the sound quality of your system, increase the flexibility of your equipment, and gain greater control over the sound.
Whether you are a musician, an audiophile, or a sound engineer, the Pre Out is an essential feature to understand and use. By unlocking the power of your amplifier’s Pre Out, you can take your sound to the next level and achieve the results you desire.
What is Pre Out on an amplifier?
Pre Out, short for Preamplifier Output, is a feature found on some amplifiers that allows users to send a low-level audio signal to another device, such as a separate power amplifier or a recording device. This feature is typically used in home audio systems, professional recording studios, and live sound applications.
The Pre Out signal is taken from the preamplifier stage of the amplifier, before the power amplifier stage. This means that the signal is not amplified to its full potential, but rather is sent out as a low-level signal that can be further amplified or processed by another device. This feature provides flexibility and allows users to customize their audio setup to suit their specific needs.
What is the purpose of Pre Out on an amplifier?
The primary purpose of Pre Out on an amplifier is to provide a way to send a low-level audio signal to another device for further amplification or processing. This feature is useful in a variety of applications, such as connecting a separate power amplifier to drive multiple speakers, or sending a signal to a recording device for further processing.
In addition to its practical applications, Pre Out can also be used to improve the overall sound quality of a system. By sending a low-level signal to a separate power amplifier, users can reduce the noise and distortion that can be introduced by the amplifier’s power stage. This can result in a cleaner and more accurate sound.
How does Pre Out work on an amplifier?
Pre Out on an amplifier works by taking the audio signal from the preamplifier stage and sending it to an output connector, usually an RCA or XLR connector. This signal is then sent to another device, such as a separate power amplifier or a recording device, where it can be further amplified or processed.
The Pre Out signal is typically a line-level signal, which means it is a low-level signal that is not amplified to its full potential. This signal is usually in the range of 1-2 volts, which is much lower than the amplified signal that is sent to the speakers. This low-level signal is designed to be amplified by another device, rather than being sent directly to speakers.
