Introduction:
Pre-out, also known as preamplifier output, is a feature found on many AV receivers that enables audio and home theatre enthusiasts to improve their listening experience. It is a type of audio output that transmits a signal from the AV receiver to an external amplifier or powered speakers. In this blog post, we will define pre-out, explain how it works, and discuss the advantages of using it in a home theatre system.

An audio/video receiver (AV receiver) is a device that receives audio and video signals from various sources, such as a cable box or streaming device, and then processes and amplifies them for playback through speakers. An AV receiver’s pre-out feature allows the user to bypass the built-in amplifier and send the audio signal to an external amplifier or powered speakers for even better and more powerful sound. This is especially useful for those who want to use high-end speakers or customize their audio setup.
In short, an AV Receiver pre-out is a type of audio output that sends a signal from the AV receiver to an external amplifier or powered speakers, allowing for better sound quality and greater flexibility when setting up a home theatre system.
Understanding Pre-Out:
To understand how pre-out works, first understand the various types of audio outputs found on AV receivers. Line-out and speaker-out are the most common outputs.
Line-out is a type of output that sends a line-level signal, which is a low-power, unamplified signal. This output is commonly used to send audio to a separate amplifier or powered speakers.
Speaker-out, on the other hand, sends a speaker-level signal, which is a higher-power signal that the AV receiver has already amplified. This type of output is commonly used to send audio to passive speakers that lack a built-in amplifier.
Pre-out, like line-out, sends a line-level signal, but it is specifically designed to send a signal from the AV receiver’s preamplifier stage. This indicates that the signal is still in its raw, unprocessed state and has not been amplified. Users can achieve even better sound quality by sending this unprocessed signal to an external amplifier or powered speakers.
It should be noted that pre-out is not a substitute for line-out or speaker-out. It is, rather, an extra feature that can be used in conjunction with the other outputs.
Pre-out is a type of audio output that sends a line-level signal from the AV receiver’s preamplifier stage to an external amplifier or powered speakers, providing a raw, unprocessed audio signal that can result in better sound quality.
Benefits of Pre-Out:
Using pre-out on an AV receiver has several advantages, including:
Improved Sound Quality: Users can achieve higher quality sound by sending a raw, unprocessed signal to an external amplifier or powered speakers. External amplifiers and powered speakers can frequently provide more power and better sound than the AV receiver’s built-in amplifier.
Flexibility in Home Theatre system Configuration: Using pre-out allows for greater flexibility in home theatre system configuration. Users have the option of using high-end speakers or creating a more customised audio setup.
Users can have greater control over the sound of their home theatre system by using an external amplifier or powered speakers. To achieve the desired sound, they can adjust the volume, bass, treble, and other settings.
Upgradeability: By using pre-out, users can upgrade their home theatre system whenever they want. They can add new speakers or amplifiers whenever they want, and they don’t have to worry about the built-in amplifier becoming obsolete or insufficient.
In summary, using pre-out on an AV Receiver improves sound quality, gives you more flexibility when setting up a home theatre system, gives you more control over sound, and allows you to upgrade.
How to use pre-out:
Using pre-out on an AV receiver is a simple process. Here are the steps to take:
Locate your AV receiver’s pre-out jacks. These are usually labelled “Pre-Out” or “Preamplifier Out” and can be found on the back of the unit.
Connect your AV receiver’s pre-out jacks to the input jacks of your external amplifier or powered speakers. Depending on the type of jacks on your AV receiver and external equipment, you can do this with RCA or XLR cables.
Select the “Pre-Out” or “Preamplifier Out” mode on the AV receiver. This is usually accomplished by pressing a button or accessing the AV receiver’s menu settings.
Turn on your external amplifier or powered speakers and make any necessary adjustments to the volume and other settings.
It is important to note that when using pre-out, the AV receiver’s built-in amplifier is not used. As a result, the speakers must be connected to an external amplifier or powered speakers rather than the AV receiver.
Before connecting your external amplifier or powered speakers, make sure they are compatible with the AV receiver.
To use pre-out on an AV receiver, connect the pre-out jacks on the AV receiver to the input jacks on the external amplifier or powered speakers, turn on the external amplifier or powered speakers, and adjust the volume and other settings as desired.
Conclusion:
For audio and home theatre enthusiasts, pre-out on an AV receiver is an essential feature. It enables the transmission of a raw, unprocessed signal to external amplifiers or powered speakers, resulting in improved sound quality and greater flexibility in the configuration of a home theatre system.
Pre-out also gives users more control over the sound of their home theatre system, as well as the ability to upgrade the system as desired.
Connecting an AV receiver’s pre-out to external amplifiers or powered speakers is a simple process, but make sure the external equipment is compatible with the AV receiver before connecting it.
Finally, if you want to improve the sound quality of your home theatre system and have more control over it, use pre-out on your AV receiver. It is a feature that any audio or home theatre enthusiast should think about.
