To connect a subwoofer to its receiver, you can use an LFE input cable or an RCA line-in cable (used for left and right input options). Assuming your subwoofer has the option to use an LFE input, this will be your best choice. But, if not, then an RCA input option will work.
Should I use both inputs on subwoofer?
Dual input allows the subwoofer an extra sensitivity adjustment. Normally, it would be enough to use a mono LFE subwoofer signal from its processor. If you have a processor with very low output so you can use a Y-splitter. By using both inputs with the same mono signal doubles the subwoofer sensitivity.
How do you hook up a subwoofer with two inputs?
if the sub has two inputs you can either just use one input or use a Y-splitter and use both. using both will add 3db to the input signal. if you were to run dual subs with two inputs on each sub you'd need a bunch of wires and a bunch of Y-splitters.
Why do subs have 2 RCA inputs?
A receiver with L+R subwoofer outputs does not, so both outputs need to be connected to the sub. Well, receivers like that are pretty rare. The dual inputs are mainly there for connecting the R/L pre-outs of a 2-channel pre-amp or pre-out equipped 2-channel stereo receiver.
What input does a subwoofer use?
The low-level input on your subwoofer will usually require a single RCA cable to connect to your AV receiver. Although you can buy dedicated 'subwoofer cables', you don't have to buy one of these if you don't want to. Any RCA interconnect will work.
Does a subwoofer need both RCA cables?
In order to hook up a powered subwoofer properly, an RCA "splitter" cable ("Y" cable) is not needed. Any single, standard RCA or subwoofer cable should do just fine. However, if the sub is exhibiting a hum with the RCA/sub cable plugged into it, then maybe try using a "shielded" subwoofer cable.
What are the outputs on my subwoofer for?
If you are using a more recent receiver, you will likely find a dedicated subwoofer output. This is meant to connect the subwoofer and streamline the LFE audio signal geared specifically for the subwoofer's bass emissions.
Is a subwoofer an input or output?
Most, but not all, subwoofers have these inputs; they get connected using speaker cables to the same speaker output jacks on your receiver or amplifier that are also hooked up to your speakers.
What is LFE input on a subwoofer?
The Low-Frequency Effects (LFE) channel found on subwoofers is known as LFE input. This LFE input channel provides you with a port where you can connect your subwoofer to a receiver. Nowadays, most subwoofers have a single LFE input channel.
