Essential Information About the BALUN/PLI05 Audio Balun
- Versatile Input and Output: Thanks to the TRS (stereo) jacks, the PLI05 can be used in balanced or unbalanced mode.
- BALUN Principle: "Balanced-Unbalanced," designed to simplify adaptation between balanced and unbalanced connections.
- Simpler Workflow: The question "balanced or unbalanced?" is handled through cabling, without changing the device.
- In Line with the Range: The PLI05 is presented as the little brother of the PLI02.

BALUN/PLI05: A Compact Format Continuing the Legacy of the PLI02
The BALUN/PLI05 fits into a very practical approach to audio: facilitating connections between equipment that do not always "speak" the same connection "language." Presented as the little brother of the PLI02, it follows the BALUN (Balanced-Unbalanced) logic in an efficiency-oriented format, making it easier to integrate an adaptation box into a pedalboard, rack, control room, or home studio setup.
Its main advantage is to focus on the essentials: a 6.35mm TRS (stereo) jack connector that allows multiple usage scenarios while remaining consistent with common audio cabling practices.
Intended Uses and Target Musicians/Technicians
The PLI05 is aimed at those who regularly connect heterogeneous sources and destinations: musicians in stage setups, sound technicians, studios, content creators, or simply users mixing studio gear, instruments, and peripherals. In these contexts, one often needs to adapt a balanced signal to unbalanced (or vice versa) depending on the connected device and the type of cable available.
Practically, if you sometimes work with balanced connections (more tolerant to environments with interference) and sometimes with unbalanced connections (very common on certain equipment), the BALUN/PLI05 allows you to maintain a reliable and flexible connection point. You save time during setup and avoid multiplying temporary solutions.
TRS Flexibility: An Input and Output Usable in Balanced or Unbalanced Mode
The key feature of the BALUN/PLI05 is the use of 6.35mm TRS (stereo) jack sockets: both on input and output. This TRS connector can carry a balanced signal (two signal conductors + ground) or be used in unbalanced mode (signal + ground), depending on how your cable is wired and the connected equipment.
BALUN: "Balanced-Unbalanced" Made Easy
"BALUN" stands for "Balanced-Unbalanced," which can be summarized as balanced/unbalanced adaptation. The advantage here is no longer getting stuck on compatibility as your setup evolves: the PLI05 is designed so that both input and output can be used in balanced or unbalanced mode, making the device particularly practical when alternating configurations.
A Simple Tool to Secure Your Daily Connections
In real life, this type of device makes a difference when you need to troubleshoot quickly, secure cabling, or standardize an audio chain without turning your setup into a puzzle of adapters. The BALUN/PLI05 precisely addresses this need: a clear solution based on TRS connectors to maintain a usable signal regardless of the type of connection expected upstream or downstream.

Questions frequently asked
Can the Palmer PLI05 Pro connect a balanced output to an unbalanced input?
The BALUN/PLI05 is designed for Balanced-Unbalanced adaptation, between balanced and unbalanced connections. Its 6.35 mm TRS Jack sockets allow this usage both at input and output.
What type of connectors does this audio adapter use?
Both the input and output use 6.35 mm TRS Jack connectors, also known as stereo jacks.
Do the PLI05âs TRS jacks support balanced wiring?
The 6.35 mm TRS Jack connectors can carry a balanced signal with two signal conductors and a ground. They can also be used unbalanced depending on the wiring and connected devices.
Is the PLI05 suitable for a pedalboard or rack?
Its compact format is designed for integration into a pedalboard, rack, mixing desk, or home studio setup. The technical specifications also indicate that it is rack-mountable.
What is the difference in positioning compared to the PLI02?
This model is presented as the little brother of the PLI02. It uses the BALUN principle in a format geared towards connections via two 6.35 mm TRS jacks.
