Understanding the Difference between XLR and TRS Cables
Before we dive into the conversion process, it’s essential to understand the differences between XLR and TRS cables.
XLR Cables
XLR cables are typically used in professional audio applications, such as recording studios, live sound systems, and broadcasting. They have a balanced signal, which means they carry both a positive and negative signal, as well as a ground wire. This balanced signal helps to reduce electromagnetic interference (EMI) and radio-frequency interference (RFI), ensuring a high-quality audio signal.
XLR cables have three pins: Pin 1 is the shield or ground, Pin 2 is the positive signal, and Pin 3 is the negative signal. This pin configuration allows for a balanced signal to be transmitted, making XLR cables ideal for applications where high-quality audio is critical.
TRS Cables
TRS cables, on the other hand, are commonly used in consumer audio applications, such as headphones, earbuds, and portable audio devices. They have an unbalanced signal, which means they only carry a single audio signal and a ground wire.
TRS cables have three conductors: the tip, ring, and sleeve. The tip carries the left audio channel, the ring carries the right audio channel, and the sleeve is the ground wire. This unbalanced signal can be prone to electromagnetic interference, making TRS cables less suitable for professional audio applications.
Why Convert a Balanced XLR to a TRS Cable?
There are several scenarios where you might need to convert a balanced XLR to a TRS cable:
Compatibility Issues
You may have a microphone or audio device with an XLR output, but your mixer, audio interface, or headphone amplifier only has TRS inputs. In this case, converting the XLR cable to a TRS cable ensures compatibility and allows you to connect your devices.
Audio Signal Quality
If you’re working with a professional audio setup, you may want to maintain a balanced signal throughout your entire signal chain. Converting an XLR cable to a TRS cable can help you achieve this, ensuring a high-quality audio signal with minimal noise and interference.
Convenience
Converting an XLR cable to a TRS cable can also be a matter of convenience. If you have a limited number of XLR cables, but need to connect multiple devices with TRS inputs, converting the XLR cable can save you time and effort.
The Conversion Process
Now that we’ve covered the basics, let’s move on to the conversion process. You’ll need the following tools and materials:
- XLR to TRS adapter or converter
- Wire stripper

- Soldering iron and solder (optional)
Method 1: Using an XLR to TRS Adapter
The simplest way to convert a balanced XLR to a TRS cable is to use an XLR to TRS adapter. These adapters are widely available online and can be purchased for a few dollars.
Connect the XLR plug to the adapter, and then connect the TRS plug to the other end of the adapter. Make sure to match the pin configuration correctly:
| XLR Pin | TRS Pin |
|---|---|
| Pin 1 (Shield) | Sleeve (Ground) |
| Pin 2 (Positive) | Tip (Left Audio) |
| Pin 3 (Negative) | Ring (Right Audio) |
Method 2: Using a Wire Stripper and Electrical Tape
If you don’t have an XLR to TRS adapter, you can use a wire stripper to modify the XLR cable directly. This method requires careful attention to detail and some patience.
Step 1: Strip the XLR Cable
Use a wire stripper to remove the outer insulation from the XLR cable, exposing the three inner wires (positive, negative, and ground).
Step 2: Identify the Wires
Identify the positive, negative, and ground wires. The positive wire is usually colored white or red, the negative wire is usually colored black, and the ground wire is usually colored shield or copper.
Step 3: Twist and Connect the Wires
Twist the positive and negative wires together, and then connect them to the tip and ring of the TRS plug, respectively. Connect the ground wire to the sleeve of the TRS plug.
Step 4: Insulate the Wires
Use electrical tape or heat shrink tubing to insulate the exposed wires and prevent them from touching each other.
Method 3: Soldering the Wires (Optional)
If you’re comfortable with soldering, you can use a soldering iron and solder to connect the wires directly to the TRS plug. This method provides a more secure connection, but requires more expertise and equipment.
Tips and Tricks
Here are some valuable tips and tricks to keep in mind when converting a balanced XLR to a TRS cable:
Pay Attention to Signal Polarity
When connecting the XLR cable to the TRS plug, make sure to maintain the correct signal polarity. Reversing the signal polarity can result in an inverted audio signal, which can cause phase issues and affect the overall sound quality.
Use High-Quality Materials
Use high-quality cables, adapters, and connectors to ensure a reliable and durable connection. Cheap or low-quality materials can lead to signal degradation, noise, and interference.
Test the Connection
Before using the converted cable, test the connection to ensure that the audio signal is being transmitted correctly. Listen for any signs of distortion, noise, or interference, and make adjustments as needed.
Conclusion
Converting a balanced XLR to a TRS cable is a relatively simple process that requires some basic tools and knowledge. By following the methods outlined in this guide, you can maintain a high-quality audio signal, ensure compatibility between devices, and overcome the limitations of incompatible cables. Remember to pay attention to signal polarity, use high-quality materials, and test the connection to ensure a reliable and durable audio signal.
What is a balance XLR cable and how does it differ from a TRS cable?
A balanced XLR cable is a type of cable that carries an audio signal in a balanced configuration, which means it has three conductors: a positive signal wire, a negative signal wire, and a ground wire. This configuration helps to reject noise and interference, making it ideal for professional audio applications. In contrast, a TRS (Tip-Ring-Sleeve) cable is a type of cable that carries an unbalanced audio signal and is commonly used for headphones and consumer audio devices.
The main difference between the two is the number of conductors and the way the signal is carried. Balanced XLR cables have three conductors, while TRS cables have only two. This makes balanced XLR cables better suited for applications where noise rejection is critical, such as in live sound or recording studios. On the other hand, TRS cables are more suitable for consumer audio applications where noise rejection is not as crucial.
Why would I need to convert a balanced XLR cable to a TRS cable?
There are several reasons why you might need to convert a balanced XLR cable to a TRS cable. For example, you might have a piece of audio equipment that only has TRS inputs, but your microphone or instrument has a balanced XLR output. In this case, you would need to convert the balanced signal to an unbalanced signal to connect the two devices. Additionally, some audio interfaces or recording software may only accept unbalanced signals, so converting a balanced XLR cable to a TRS cable can help you connect your equipment to these devices.
Converting a balanced XLR cable to a TRS cable can also be useful in situations where you need to connect a professional audio device to a consumer audio device. For example, if you want to connect a professional microphone to a consumer-grade audio interface, you would need to convert the balanced XLR output of the microphone to an unbalanced TRS signal that the interface can accept.
