Can I Connect the Subwoofer to Pre-Out?

Well, you can connect the subwoofer to the Pre Out, but there are a few things you will need to make the connection complete and adequate. First, you need to have access to the sub cable with not only the regular RCA cable but also RCA plugs that work well. The connection is effective in boosting your low-frequency output on the sub.

Before going through the Subwoofer Pre-Out connection, we would also like to understand a pre-out. Subwoofer Pre Out is simply an audio output or, instead, an output port that sends to the subwoofer a low-frequency signal. Thus, this Subwoofer Pre Out is designed to connect the subwoofer to the receiver directly. This dedicated connection is often called the Pre-out and sometimes the subwoofer-out.

This indicates that the pre-out features are typically located at the higher-end receivers. This is a very vital feature that is usually used to even power on the subwoofer without a separate and dedicated amp. If you can connect the subwoofer to the Pre-out, the answer is yes because the feature is designed to connect the external amp to the powered sub to give you a low-level audio frequency.

This does not come with any amplification interference. Pre-Out is different from the other typical audio outputs found on the receiver. First, these Pre-out can only transmit a low-frequency audio signal to the sub directly instead of all the frequencies simultaneously. This gives your sound output or speakers the power to reproduce the same low frequency with guaranteed clarity and depth.

Let us now move to the step-by-step procedure in the next section.

How to Connect a Subwoofer to a Pre-Out?

Here, we are talking about integrating the AV Receiver with the subwoofer, which is a vital process for setting up your favorite sound system at home or in a theater room. The subwoofer plays a vital role in giving you not only the low-frequency audio signal but also provides the much-needed richness and sound wave depth for the cinematic experience.

These AV receivers mostly have the Pre-out port to make the connection easy. But in case the subwoofer does not have the relevant Pre-Out, then you must consider using the speaker level output or instead opt for the tape out. To make things easy, we will explore the steps on how to go about connecting the sub to the AV receiver Pre-Out. Here we go:-

Start by ensuring you have the mono cable, sometimes the standard RCA male-to-male.
Second, check the type of the subwoofer and make sure it is a powered subwoofer. The active subwoofers are ready to establish the connection directly using the pe-Out receiver since they come with inbuilt amps. If you are using a passive sub, then you can never connect the to directly to the pre-out since they never feature that in-built amp. Pre-out cannot solely drive the passive subwoofer since it is only designed to connect the external power amp. Therefore, for the passive sub, you must connect through the external power amp to give you enough driving power on the sub. You will have to connect the pre-out through the input of a particular selected external power amp, then proceed by connecting to your passive sub using the power amp output. Assuming you have the active sub, proceed with the next step.
Select the correct cable that will match the setup you have at hand as well as fit the preferences you have in mind. The cable you will get highly depends on the approach you wish to use while connecting. You can go for the regular RCA to subwoofer cable. When your sub has a single RCA input, utilize the source cable to directly link to that Pre-Out found on the AV receiver port. But when the sub comes with right as well as left RCA input, consider using a Y-Cable to connect the Pre-Out found on the AV receiver. It is important to have the relevant cable at hand to ensure the connection works well, and in the end, you will get to enjoy high-quality sound or audio.
Next, connect the RCA cable to your AV receiver. Immediately after you are done selecting the suitable cable, then continue to connect the tip to your pre-out port on the subwoofer. In most cases, the AV receivers feature the pre-outs located at the rear panels with the relevant label.
Then, connect the other end to the right as well as to the left RCA line-in inputs found on the sub. You can connect the end using the left or the right RCA line-in inputs. They are located behind your sub with a particular label. Hence, insert the RCA connectors to all the line-in inputs found on the sub and make sure these connectors are fully inserted as well as secure.
Finalize by turning on the receiver and the sub simultaneously, and please keep the initial volume low.
Lastly, play some bass-rich music and adjust the volume and the crossover settings based on personal preferences. Before the final two steps, you must ensure that these connections and cables are intact and there is no looseness.

In case there is any issue, or there is no sound produced in your subwoofer, then you must double-check the connection and justify that everything is working effectively. Refer to one of our articles on how to troubleshoot an amp that is powered on but has no sound from speakers.

Conclusion

Sure, you connect the subwoofer to the pre-out or the AV receiver using an effortless procedure. However, it would be best to have the right cables to make the work more straightforward and practical to match the setup, plans, and preferences. In the above article, we have explored the step-by-step procedure for connecting the sub to the AV receiver Pre-Out.

We have also seen what a pre-out is and the appropriate cables you need for the powered and passive subwoofer. Follow the above procedure keenly, and you can securely link the component for the cinematic high-quality audio or sound in your home theater or system.
