The essentials to know about the PPB 20 stereo distribution box
- Stereo version designed as a complement to the “normal” mono version.
- Two line inputs instead of one microphone input and one line input.
- Clear channel distribution: input 1 feeds the odd-numbered channels, while input 2 feeds the even-numbered channels.
- Row-based layout: odd-numbered channels on the upper row of outputs, even-numbered channels on the lower row.

A Stereo Version Designed to Simplify Routing
The PPB 20 is also available in a stereo version, a practical alternative to the mono version when your setup relies primarily on line-level signals. The idea is simple: instead of combining a microphone input and a line input, this version provides two line inputs for more consistent connections in studio, live, or rack environments.
Who Is the PPB 20 Stereo For, and When Should You Use It?
This version is particularly well suited if you need to distribute a stereo signal cleanly (or two separate line sources) to multiple outputs, while keeping the channels easy to identify at a glance. The odd/even separation maintains an efficient cabling layout, which is useful when you want to save time during setup and reduce patching errors.
Output Distribution: A Clear Odd/Even Layout
Input 1: Odd Channels (Upper Row)
The first line input is distributed across the upper row of outputs, corresponding to the odd channels. This allows you to quickly visualize the signal path while maintaining consistent numbering across the entire row.
Input 2: Even Channels (Lower Row)
The second line input is distributed across the even channels, corresponding to the lower row of outputs. This row-based separation makes it easier to identify left and right in a stereo setup, or simply to distinguish between two line circuits.

Questions frequently asked
Does the Palmer PPB 20S Pro accept two line sources?
This model features 2 line inputs, with no microphone input indicated in this stereo version.
How are the outputs from line input 1 distributed?
Line input 1 is routed to the upper row of outputs. It corresponds to the odd channels. This setup simplifies tracing the first line circuit in a patch.
Do the even channels correspond to the second input?
The second line input feeds the lower row, corresponding to the even channels.
Is it possible to distribute a stereo signal with this model?
A stereo signal can be distributed using the 2 separate line inputs on the odd and even rows. The first input can be assigned to the odd channels, and the second to the even channels.
What is the difference between the PPB 20S Pro and the mono version?
This stereo version replaces the combination of one microphone input and one line input with 2 line inputs. A standard mono version of the PPB 20 also exists.
