Mix multiple audio signals together from TRS cables?



Asked by: Cynthia Collazo

How do I merge two audio signals?





The simplest way to combine two signals is with two resistors as shown in the circuit diagram below. The ground connecton is shared between both inputs and output. The quality can be improved by adding an output buffer (opamp), but that complicates things in requiring an IC, power supply, (de)coupling caps,

Can I use TRS cable instead of TS?

TS cables are generally used for mono, unbalanced signals. These are most commonly used with electric guitars. TRS cables can be used for mono, balanced signals as well as stereo signals. An example of a mono, balanced signal would be the line in or out from your audio interface.

What is TRS audio cable?

The letters TRS stand for Tip, Ring, and Sleeve, and refer to the parts of the jack plug that the different conductors are connected to. A TRS cable has three conductors vs the two on a standard guitar cable. A guitar cable is a TS, or Tip Sleeve cable. The jack plug at the top is a TS jack.

What’s the difference between an audio interface and a mixer?

What is the basic difference between an audio interface and a mixer? Basically, an audio interface is designed to record clean signals onto your computer on separate tracks. The mixer is designed to mix multiple audio sources into one stereo stream.

What happens if you plug a TS cable into a TRS jack?





When you plug a ‘TS’ plug into a TRS balanced jack socket, the “ring and sleeve” are bridged. This is exactly the correct way to unbalance a balanced connection. It works in the way it was designed to. Additionally, by unbalancing that output connection, you reduce the level of the output by 6dB.

Can I use a TRS cable in an unbalanced output?

Not a problem to use a balanced TRS cable on an unbalanced source. The wire that runs from ring to ring is simply not used. Not sure what happens if you then go into a balanced input. That input might require the ring to be grounded.

Can I plug a guitar into a TRS input?

TRS cables will work with a guitar in most cases, but because they are a balanced cable, and a guitar has an unbalanced output they will make no difference to your sound.

Can TRS connectors carry unbalanced signals Why or why not?

TRS cables feature the tip-ring-sleeve (TRS) design, which makes them suitable for both carrying a balanced mono signal, or an unbalanced stereo signal. To conclude, if you’re using the TRS cable to carry a balanced mono signal, you don’t need to worry too much about its length.

Can you have a balanced TRS cable?

TRS stands for tip, ring, sleeve, and can be used to send either mono (balanced) or stereo (unbalanced) signals.

Is balanced TRS the same as stereo?

A stereo, unbalanced signal requires a TRS plug – tip is left, ring is right, sleeve is audio ground for the left and the right signals. A stereo, balanced signal requires a plug with FIVE connection points, not three like a TRS plug. A five pin XLR plug can handle a stereo, balanced signal.



Is TRS balanced mono?

A balanced audio cable, such as an XLR or TRS, is a mono cable.

Can TRS carry stereo?

A TRS cable can carry either a balanced audio signal or a stereo audio signal. It depends on what audio output you connect the cable to. People often ask, “Are the TRS cables balanced?” The answer is “They can be, if you connect the cable between a balanced TRS output and balanced TRS input.”

How do I know if my TRS cable is balanced?

If the cable has two points of contact, it’s unbalanced; and if it has three, it’s balanced.
