RTS 4025A 1×4 25-Pair 50-Pin Passive Splitter / 1 Input 4 Outputs / Passive Operation

Description

The 4025A is a passive 1×4 splitter designed to distribute 25-pair, 50-pin intercom signals across multiple endpoints. It provides one input and four identical outputs to enable parallel connections to master stations or IFB control panels. The unit requires no external power and maintains signal integrity through passive wiring.

Key features include four isolated outputs that mirror the single input, standard 25-pair 50-pin connectors for industry cabling, and a compact low-profile enclosure. The passive architecture eliminates the need for power supplies and reduces points of failure in concise intercom installations. Connectors are arranged to support straightforward cable routing and system layout.

Technically, the 4025A passes all 25-pair signals without active conditioning, preserving the original audio and signaling characteristics. The lack of active electronics means negligible power consumption and minimal maintenance. Physical dimensions and lightweight construction make it suitable for dense rack or desk-top environments.

Connectivity is provided through standard 25-pair 50-pin connectors on the input and every output, ensuring compatibility with existing RTS 800-series and 4000-series master stations and IFB panels. The splitter supports common intercom wiring conventions and interfaces directly with industry-standard multicore cabling. No special adapters or converters are required when used with compatible equipment.

Typical use cases include broadcast production facilities that need to feed multiple control panels from one source, live event routing where redundant feeds are desirable, and studio environments that require simple passive distribution of intercom lines. The unit works well where passive splitting is preferred over active distribution for simplicity and reliability. It is particularly useful in systems where minimizing power and heat is important.

Installation is straightforward and requires only proper cable termination and secure mounting where needed. The compact footprint and light weight allow quick deployment and repositioning in technical racks or on work surfaces. Build quality emphasizes reliable connectors and straightforward wiring to reduce installation time and long-term service requirements.
