Description
Palmer PB 20 20-Channel Conference Audio Signal Splitter The Palmer PB 20 is a professional conference audio signal splitter designed for sound engineers, press conferences, broadcast events, and demanding live audio applications. This advanced distribution system allows a single audio source to be safely and reliably distributed to up to 20 independent outputs, making it the perfect solution for television crews, recording teams, streaming setups, and large-scale conference environments. Thanks to transformer-balanced XLR outputs and a high-quality input amplifier stage, the Palmer PB 20 delivers clean audio transmission, extremely low noise levels, and dependable operation even in challenging technical conditions.
Main Features The unit is equipped with 20 independent XLR outputs featuring individual driver circuits and Ground Lift switches located on the rear panel. This design effectively minimizes ground loop issues and unwanted interference when multiple recording or broadcast devices are connected simultaneously. A versatile microphone/line input stage combined with adjustable Gain control and a +20 dB switch allows precise level matching for a wide range of audio sources.
The front panel includes a clear LED level meter displaying signal levels from -40 dB to +10 dB for accurate monitoring during operation. An integrated headphone amplifier with dedicated volume control enables direct audio monitoring without the need for external equipment. Channels 19 and 20 additionally provide RCA and 6.3 mm TRS outputs, offering enhanced compatibility with various professional and consumer audio devices.
Designed for Professional Conferences and Broadcast Applications Modern press conferences, corporate events, television productions, and live streaming setups require stable and reliable audio distribution. The Palmer PB 20 was specifically engineered for these demanding environments. By distributing one input signal to 20 isolated outputs, the system allows multiple recording teams and broadcast devices to receive the same audio feed simultaneously without compromising sound quality.
In practical applications, this means you can connect cameras, digital recorders, broadcast mixers, and monitoring systems at the same time while maintaining excellent audio integrity. Transformer isolation on the outputs ensures stable performance even with long cable runs and in environments exposed to electromagnetic interference. This level of reliability is essential during professional live productions where uninterrupted signal flow is critical.
The PB 20 also supports cascading multiple units via BUS IN/OUT connectors, allowing easy expansion for larger installations and more complex conference systems. Additionally, the splitter supports external DC backup power operation, increasing operational security during live events and mission-critical productions.
Applications This professional conference signal splitter is ideal for press conferences, corporate meetings, broadcast productions, live streaming, event staging, and mobile recording applications. It is also an excellent choice for conference centers, government institutions, AV installation companies, and professional production teams requiring dependable audio distribution.
With 20 independent outputs, the Palmer PB 20 allows multiple devices to receive the same audio source without requiring additional splitters or distribution amplifiers. The unit is equally suitable for permanent installations and portable event systems where high-quality signal routing is essential.
