This has to do with the frequency range of the different mics, voices, and instruments. With a lot going on at one time, this allows you to pull out and adjust only the areas needed going to the subwoofer. Then you would increase or decrease the Aux knob on each channel depending on which one you want to send to the subwoofer. This connection scheme gives you the most control over what goes to the subwoofer, helping you have a cleaner mix avoiding muddiness in the sound.
Choose the one that is more practical for you. If you have passive speakers, method 1 would be the best option. The reason is that with an external crossover, you would be able to divide the frequencies in Hi, Mids, and Lows, then send the corresponding frequency to each amplifier.
Instead, if you are using powered or active speakers, method 2 would be perfect for you. Just make sure that the subwoofer you purchase comes with an active crossover. The third method works perfectly well if you need more control over which channels go to the subwoofer. That way, you get a cleaner mix avoiding any muddiness in the sound.
It uses a single cable to connect to your receiver or preamp line output. Your AV receiver gets all the signals from different input devices. The equipment will then figure out what these signals are and then amplifies it. Lastly, the receiver will send the signals out to the output devices, such as your subwoofer, speaker, sound system, projector, and TV. Experts and enthusiasts call the AV receiver the heart, brain, or hub of your home theater system. But what exactly does it do?
Your AV receiver manages the different video and audio sources. It has a preamplifier section that lets you switch or select the audio source to listen to or the content you want to watch. The receiver will allow you to enjoy the content you want no matter which devices they are on with only a switch of a button. Aside from allowing you to manage and switch from one video and audio source to another, your AV receiver can also allow you to do other things. We list them below.
The thing with AV receivers is that you will probably have a lot of ports, switches, and toggles, and that can usually mean lots of wires. The good news is that if you are trying to connect subwoofers to your receivers, you only have to worry about one of these two areas : the speaker connectors and the pre-out.
The pre-out section is where you would find the connectors for audio equipment that have built-in amplifiers. As such, if you have a powered subwoofer, you will be using one of the ports in this section to connect it to the receiver.
The pre-out section is also very useful if you want to have more speakers in your setup or if you want to utilize a standalone amplifier. Powered subwoofers, and any piece of equipment that is wired and have their own built-in amplifiers, can be plugged in the pre-out section.
But passive subwoofers need to be connected using one of the speaker connectors. As you can see, there are two main options for you to connect a passive subwoofer to an AV receiver depending on the setup that you have. If you have AV receivers designed to connect to an active subwoofer, a Japanese electronics manufacturer, Denon, does not recommend connecting a passive subwoofer directly to your AV receiver.
Instead, the company suggests the following steps:. Alternatively, you can also try connecting your passive subwoofer right where you would connect your speakers on the receiver. On the other hand, active or powered subwoofers are self-contained. It features a speaker or amplifier configuration in which the characteristics of the amp and subwoofer speaker are optimally matched and encased in the same enclosure.
For this type of sub, you do not need an external amp. There are pros and cons to each type of sub, and it really depends on many factors, such as your budget, the sound quality you are looking for, and the space you have. Passive subwoofers are more lightweight since they have fewer components.
They are also easier to maintain. Some users may argue that powered subs are better because their built-in amplifiers allow you a worry-free experience.
However, active subwoofers are more popular because they produce a deeper, more impactful sound without requiring extra components. Even if you plug the passive subwoofer into an external amplifier, you can still reposition the amp in the future to improve the sound quality. It can get dangerous because passive subwoofers require a lot of power to reproduce the bass.
As a result, there is a possibility that your receiver may not deliver the required power for your subwoofer to function optimally. Keep in mind that you might even blow the receiver if you are not careful with your sub! The chances of this happening are definitely higher for older and lower quality gadgets, though. Receivers are made with many switches, ports, and toggles. Wiring is definitely required to complete the connection between a subwoofer and a receiver.
This is referring to whether or not you have an active or a passive sub. All of this information is then transferred down into your passive sub. You will need to have your passive subwoofer wired to one of the speaker connectors. Then you can connect the speaker wire to the speaker line of the subwoofer. Be very careful that your sub is not pulling too much power beyond what the receiver can supply. This can result in overheating and become flammable. Another quick and easy way to connect passive subs to your AV or audiovisual receiver is the use the Zone 2 ports on the receiver.
