Why do some subwoofers have left and right inputs?

Why do some subwoofers have left and right inputs?

The left and right channels are combined in an LFE cable to allow for a singular cable to evenly disperse the signals to the subwoofer. Rather than having to sort through various cords and cables, you can use an LFE input as a single cable to connect your subwoofer to its receiver.

Why do subwoofers have 2 RCA inputs?

Dual input allows the subwoofer an extra sensitivity adjustment. Normally, it would be enough to use a mono LFE subwoofer signal from its processor. By using both inputs with the same mono signal doubles the subwoofer sensitivity. This means that there is now only half the signal strength to drive it to full output.

Does Left and Right matter subwoofer?

Hooking Up Your Subwoofer Most subwoofers have both a left & right input. It usually doesn’t matter which one you use. If you are using more than one subwoofer, you can run the same kind of cable from the subwoofer’s “line out” or “low level out” to the next subwoofer.

What are RCA inputs for subwoofer?

RCA-RCA Low Level 1/LFE subwoofer output on the rear of your receiver and outputs, typically, a theatre-centric signal to your new subwoofer. It uses the ubiquitous RCA cable and plugs in similar to how tuners or CD players have done so for decades. It’s easy and works fine for relatively short runs of, say, 25′ or so.

Can you use RCA for LFE?

Any single, standard RCA or subwoofer cable should do just fine. The other end of the cable will be plugged into the L/LFE (white) RCA jack on the back of your sub. Any cable designed for subwoofer use should be just fine.

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 is the difference between high level input and low level input?

So what is the difference between the two? High-Level (Speaker Level) Inputs: Speaker level inputs are commonly referred to as high-level inputs and vice versa. Speaker level inputs are used when you want to connect an amplifier to your factory radio or an aftermarket radio that does not have low-level (RCA) inputs.

What is the difference between line level input and speaker level input?

Speaker level signals are post-amplification. After a line-level signal enters an amplifier, it exists to the speakers at what is called speaker level. These signals are much higher in voltage than line level and require speaker cables for safe signal transfer.

Is RCA cable same as LFE cable?

Ways to Connect Subwoofer There’re many ways to connect a subwoofer, but in 99\% of cases, this is an LFE connection type. Most subwoofers require a single long cable with RCA connector. Connect it to the output of the AV receiver preamp and to an LFE (low-frequency effect) port of a subwoofer.
