Palmer PB 10 – 10-Channel Conference Audio Signal Splitter

Palmer PB 10 is a professional conference audio signal splitter designed for stage, broadcast and conference applications. The unit was created for situations where one audio source needs to be safely and reliably distributed to multiple independent outputs. Thanks to transformer-isolated outputs and a rugged 19” rackmount construction, this model performs perfectly during press conferences, live broadcasts, media events and professional sound reinforcement installations.

Product Features

The unit allows distribution of one line-level audio signal to up to 10 independent XLR outputs. All inputs and outputs are balanced and transformer-isolated, significantly reducing the risk of hum, interference and ground loop problems. Each output features an individual Ground Lift switch, enabling quick elimination of unwanted noise.

The splitter also offers adjustable input gain ranging from -8 dB to +25 dB, making it easy to match different audio sources. An integrated level meter provides fast signal monitoring, while the headphone output with volume control enables convenient real-time monitoring.

Reliable Audio Distribution for Conferences and Broadcast Applications

In professional audio environments, stable signal transmission and safe distribution to multiple receivers are essential. Palmer PB 10 was specifically developed for these demanding tasks. Thanks to transformer-based signal distribution technology, the unit delivers clean, stable and interference-free audio even in challenging working conditions.

This solution is ideal for press conferences where one microphone signal needs to be sent simultaneously to multiple cameras, recorders or journalist stations. Transformer isolation ensures that each output operates independently – even if one connected device fails or causes a short circuit, the remaining outputs continue functioning correctly.

A major advantage of the unit is its expandability via Bus In/Out connectors. This allows cascading multiple PPB10 or PPB20 units, making it possible to build large-scale signal distribution systems for major media events and broadcast installations.

Applications

The signal splitter is suitable for a wide range of professional audio applications, including:

• press conferences and media events
• live broadcast productions
• professional sound installations
• conference systems
• recording and television studios
• microphone and line signal distribution
• events requiring multiple audio recording feeds
