The Palmer peene is a professional 2-channel passive line splitter designed for event technology, studio, TV, and broadcast applications. It allows you to split a signal source into multiple outputs, such as power amplifiers or active speakers, while maintaining signal integrity and preventing hum loops using high-quality isolating transformers.
Connections and Operating Elements
The device features the following inputs and outputs:
- INPUT 1 / INPUT 2: Balanced line inputs with female 3-pin XLR sockets for channel 1 and 2.
- THRU 1 / THRU 2: Balanced line outputs with male 3-pin XLR connectors. These are wired directly to the corresponding inputs.
- OUTPUT 1A / 1B & OUTPUT 2A / 2B: Balanced line outputs with male 3-pin XLR sockets. These outputs are decoupled from the line input via high-quality isolating transformers.
- LIFT / GND: A switch used to disconnect the ground connection between inputs and outputs. This is useful for eliminating hum loops.
Safety Instructions
- The device is intended for professional use only by qualified personnel.
- Do not open the device or perform any modifications.
- Keep the device and packaging away from children due to small parts and plastic bags (choking hazard).
- Ensure input channels (mixer, audio interface) are muted before connecting cables to avoid noise damage.
- Do not place the unit near strong magnetic fields, such as mains transformers, to avoid humming.
Wiring Example
The device is typically placed between a signal source (like a mixer) and multiple destination devices (like PA systems). Connect your source to the INPUTs and route the signals to your amplifiers or active speakers using the OUTPUTs or THRU connections.

Practical help
Common problems
Humming noise
Use the Ground Lift switch to disconnect the ground connection. Try both positions (pressed/unpressed) to see which eliminates the hum.
Before use
- Ensure input channels are muted before connecting cables to avoid noise damage.
- Use balanced XLR cables for connections.
- Do not place the unit near strong magnetic fields (e.g., mains transformers).
