Can pre-OUT be used for subwoofer?

A common usage of the pre-out is with a subwoofer. Subwoofers have their own internal amplifier, and it is often beneficial to use a pre-out connection in this scenario. Many subwoofers and other speakers will include their own amplifier. Known as Active Speakers, these should use a pre-out connection.

How do you hook up a subwoofer to a receiver pre-out?

Just plug the subwoofer cable into your receiver’s subwoofer pre-out and the other end into the Y-adapter on your sub (which is connected to the left and right RCA line-in inputs). Then make sure the power plug is connected to an outlet (hopefully in a surge protector) and you’re finished.

How do you check subwoofer output on a receiver?

The receiver sub-woofer output is line level. So to test you could connect to a line level input (e.g., Aux) of a separate amplifier and listen through headphones or speakers that can handle low bass frequencies while playing something with low bass content through the receiver you are testing.

Can you connect subwoofer to speaker output?

You can connect a subwoofer to the high (speaker) level connections with speaker wires or a speaker connector. Check the specifications on your subwoofer beforehand. Using high (speaker) level connections will use the same audio signal for other speakers allowing for more precisely-timed bass.

Why does my receiver have two subwoofer outputs?

When a receiver has dual subwoofer outputs the two are typically duplicates of each other with a common internal connection. If they are independent, and you have only one subwoofer, then simply choose one of them and indicate in the receiver setup which one you have chosen to use.

How do I know if my sub is blown with a multimeter?

Subwoofers and speakers mostly blow when you deliver very high power or if they continue to work for a long time above the RMS power. When you hear a distorted sound or no sound at all, it indicates that subwoofer is blown. You can also know this by touching the voice coil if it is moving at its place or not.

Where is the pre out on a sub woofer?

Here’s a picture of a receiver’s preouts. Notice the one labeled Sub Woofer. It is typically purple in color, but that’s not always the case. You should see a similar jack on your receiver, and 99% of the time of it will be in a group labeled pre-out. If you’re not using a subwoofer cable, a composite audio cable will work up to about 10ft.

How to connect a subwoofer to a receiver without a speaker?

Example of a powered subwoofer with 2 types of signal inputs (speaker level and RCA jacks) along with sound controls. Note: Not all subwoofers have speaker level inputs, which makes it a problem connecting them to a receiver without a subwoofer output.

Why do I not get thumping sound from my subwoofer?

If you do not hear a thumping sound then there is a possible service issue with the subwoofer. Connect the other end of the subwoofer cable to the subwoofer audio output connector on the back of the receiver. NOTE: Some receiver models may have two outputs to drive two subwoofers.

How do I get a pre out on my speakers?

First, identify if your speakers will be using the receiver’s amp or an external amp. For the speakers with an external amplifier, locate the corresponding pre-out connection on the receiver. For example, when connecting your subwoofer via a pre-out, there are a few different connection options.

Can a subwoofer be connected to a preamp?

In spite of the name, a ‘subwoofer out’ isn’t the best way to connect a subwoofer to a quality music system. The preferred method works even if a preamp doesn’t have special subwoofer or preamp outputs, however, you do need a subwoofer that can accept a “high level” (also called “speaker level”) input.
