I especially loved the reference to "power chords" lol At the end, when the negative signal is inverted again, I understand the noise will be cancelled, but wouldn't the original signal be now doubled since it is inverted back on the negative signal?
Think of it like this. Does that make sense? Hi, kind of : From the original post: "Then you take that exact waveform and duplicate it onto channel two. So, in the end, inverting back one of the channels and adding one to another, by logic, will make the result doubled. Or am I missing something? Want to join the discussion? Featured Articles.

They are also able to deliver balanced mono and unbalanced stereo signals. External line return XLR cables are always balanced cables that only hold balanced signals. They are typically used to connect microphones, speakers, and other XLR compatible devices. These cables are identified by their three-prong design, representing the signal wires and the ground wire. Because of the similar design, it is common to use them in place of TS cables since they can carry both an unbalanced or balanced signal.
The three rings can identify a TRS on the connector representing the signal wires and the ground wire. Instead, the cable transports digital messages between the connection points. USB microphones, like a Blue Yeti, convert an analog signal into a digital message that is then sent and unpacked by another device or program.
Most modern-day instruments, like electronic keyboards, come with a MIDI connection port. Like USB, the connection delivers a digital message between an instrument and a program, usually a digital workstation.
Overall, most gamers or streamers will use balanced cables over unbalanced. This is because standard gaming audio equipment, like microphones and wired headphones, uses balanced cables.
Additionally, the advantages of balanced cables make for the ideal solution when trying to attain the perfect audio mix. Balanced audio solves that issue with a design based on reversing the polarity of any noise generated along its run.
Ideally, you want to use balanced audio when possible but the use of balanced audio is determined by the devices generating the signal, not the cable. You cannot connect a balanced TRS cable to a device with an unbalanced TS output and get a balanced signal.
Lots of audio equipment still uses unbalanced audio. Best practice when using unbalanced signals is to keep your cable runs short. Take the time to understand the connector types and the signal transfer formats before you begin researching the cable you wish to buy.
Knowing this information before you go shopping for cables will save you time, which is better spent putting your new pro audio equipment to use. What are Unbalanced Cables? Unbalanced Cable Connectors Some connector types are inherently unbalanced, so any time you see them present, you know that particular connection is one half of a balanced signal, or a single unbalanced input.
RCA RCA connectors, or phono connectors because of their original use with phonograph players, are used in a lot of audio equipment. What are Balanced Cables? Balanced Cable Connectors Just like unbalanced cables, sometimes you can tell which cables are balanced just by the connectors that are used. XLR XLR cables most commonly feature three pins, though they can be found with four or five pins in some applications. Pros and Cons of Balanced vs.
In some cases, a wireless rig is a great though potentially pricey option. Learn more about direct boxes in this post. Tags: audio fundamentals , digital audio , how to , live , studio , tips. Thanks for the explanation. Or is the signal split at the beginning of the run, one half is flipped, then flipped back, then you have the sum of 1 signal and no noise?
When the reversed original signal is returned to its normal polarity, the noise picked up by the cable gets canceled because its polarity is now opposite of that on the other signal wire in the cable. Based on what read in this article and the DI boxes article , seems i may be doing my setup wrong. I have an Apollo twin interface i use to send my soft synths audio in MainStage to the front of house when playing at my church.
Based on what this article says, i really do not need the DI box or the TS cables for this particular set up… right? It seems i am only converting balanced signal from my apollo to unbalanced to the DI and then converting it back to balanced to stage box…? I know TR cables loose signal when run long lengths and that XLR cables can run long lengths without loosing much signal. Your audio interface is providing a balanced line-level signal.
Remember, the stage box and the multi-core cable that runs to the FOH console is just a fancy extension cord for audio. The console should be able to accept your line-level audio signal.
Very Well eXplained and really helpful, since no one could ever explain it to me that way!!! Good job!! If I understand correctly it will work just fine right? Most balanced devices can work with an unbalanced input. Clear explanation of what happens when you use a balanced cable with unbalanced connections and viceversa. Now, what happens if you have a balanced source and an unbalanced input? You would certainly need an XLR to 3.
Or are both types of XLR to 3. You get no noise reducing benefit from the balanced wiring coming from the mic in this case. So if i plug unbalanced cable to source and the balanced side to a speaker… The noise would still be here? If you start with an unbalanced source and an unbalanced cable two wires that signal will remain unbalanced when you plug it into a balanced input. A balanced circuit needs to be three wires positive, negative, and ground all the way through.
Thanks for the clear explanation.
