Cables are often the unsung heroes of an audio setup. They ensure that your sound travels from one component to another without dropouts, interference, or noise. Well-made cables maintain clean signal integrity, reduce the risk of performance disruptions, and bring order to otherwise chaotic rigs. From live performances to studio sessions, having the right cables is essential for getting the most out of your equipment.

Understanding how vital cables are to professional audio workflows, Phenyx Pro has developed two high-performance, four-channel snake cables tailored to meet different connection needs. The PCBL-4IN1 XLR Snake Cable, our first release, was meticulously engineered to seamlessly integrate with the majority of Phenyx Pro audio devices. Building on this foundation, we’ve introduced the PCBL-QR4IN1 TRS Snake Cable, designed specifically to meet the demand for 1/4” TRS connectivity.

Common Advantages of Both Cables

Both the PCBL-4IN1 and PCBL-QR4IN1 are engineered to deliver exceptional audio performance, with several shared benefits designed for seamless integration into your professional setup:

1. Four-Channel Design for Streamlined Setup

Both cables feature a four-in-one design, combining four independent audio channels into a single cable that transmits four distinct audio signals simultaneously. This streamlined design reduces cable clutter, and ensures a more organized and efficient setup.

2. 24AWG Oxygen-Free Copper for Clear Signal Transmission

Both cables feature 24 AWG oxygen-free copper (OFC) conductors, ensuring clear, high-fidelity sound with minimal signal loss. Built for balanced audio transmission, they reduce unwanted noise and deliver clean, consistent performance across a wide range of setups.

3. Enhanced Shielding for Noise Protection

Advanced double-layer aluminum foil and spiral copper shielding block EMI and RF interference, reducing crosstalk by up to 98%. This ensures crystal-clear, high-speed audio signals, even in environments with significant electronic noise.

4. PVC Outer Protection for Higher Durability

The thickened PVC outer layer protects the cables from wear and tear, while remaining soft and flexible enough for easy positioning—no tangling or kinks during setup or storage.

5. Color Coding and Numbering for Easy Management

Each channel is clearly marked with color and number coding, making it easy to identify connections at a glance. This is especially helpful during quick changes or troubleshooting.

6. Multiple Lengths for Versatile Use

Available in 3FT, 6FT, and 10FT options, these cables adapt to different setups—from tight racks to wider stage layouts—while maintaining a clean and tidy signal chain.

Differences Between the Two Cables

Although the PCBL-4IN1 and PCBL-QR4IN1 share many high-performance features, their key differences lie mainly in the connector types and specific functions. Depending on your audio equipment and use case, choosing the right connection type is crucial. Next, we will explore the unique features of these two cables to help you make the best choice.

1. XLR vs. TRS Connector

• The XLR connector (also known as the Cannon connector) is a three-pin balanced audio interface that transmits signals through three conductors: positive, negative, and ground. By using the principle of phase cancellation, it effectively eliminates noise, enabling clean, high-quality audio.
• The TRS connector also uses three conductors—Tip, Ring, and Sleeve—and is capable of transmitting either balanced audio or stereo signals, depending on the application. In the PCBL-QR4IN1, we use TRS connectors specifically configured for balanced audio, allowing them to connect seamlessly with equipment that has balanced 1/4" inputs. This configuration helps minimize noise interference and enhances overall signal clarity.
  Note: Always verify compatibility before connecting. Using a balanced TRS plug with an unbalanced TRS jack can result in signal loss, distortion, or even damage to your equipment. Refer to your device's specifications and use proper adapters when needed.

2. Phantom Power Capability

• The XLR connector supports phantom power, which supplies DC power to devices like condenser microphones, essential in recording and professional audio setups.
• In contrast, TRS connectors are not designed to carry phantom power due to their unbalanced voltage distribution. Unlike XLR, they lack symmetrical power delivery across signal lines, which can lead to interference, equipment damage, or electrical hazards when phantom power is applied.

3. Locking vs. Non-Locking Mechanisms

• The XLR connector features a locking mechanism that secures the connection in place, reducing the risk of accidental disconnections during movement or cable handling.
• The TRS connector lacks a locking design, allowing for quick and easy connections—well-suited for environments where cables are not frequently moved or disturbed.
