The Telex TW-5W is a professional audio distribution amplifier, commonly referred to as a "splitter box," designed to take a single microphone or line-level input signal and provide five isolated, buffered outputs. Its primary function is to solve a common signal routing challenge in professional audio systems: distributing a critical audio source—such as a podium microphone, program feed, or recorded playback—to multiple destinations without signal degradation, ground loops, or loading issues. This ensures that each receiving device, such as a front-of-house console, broadcast feed, recording device, monitor console, or streaming encoder, receives an identical, clean copy of the source signal.

Engineered for reliability in live sound, broadcast, and installed environments, the TW-5W features a rugged metal housing with a straightforward design. It accepts a balanced input via an XLR connector and provides five transformer-isolated balanced outputs on XLR connectors. This transformer isolation is key, as it provides complete electrical separation between the input and each output, preventing hum caused by ground loops and protecting downstream equipment from potential DC voltage differences. The unit is passively wired and requires no external power, making it extremely reliable and simple to integrate into any signal chain.

As a fundamental problem-solving component, the Telex TW-5W is a staple in audio toolkits for touring, houses of worship, conference centers, and broadcast trucks. By providing multiple, clean splits from one source, it enhances system flexibility, simplifies complex setups, and ensures signal integrity throughout the audio distribution network. Its passive, transformer-isolated design guarantees consistent performance and protects sensitive equipment in professional multi-destination audio applications.
