The Roland S-4000D Digital Snake Splitter and Power Distributor is a sophisticated system component designed to enhance the flexibility and scalability of professional digital audio networks, particularly within Roland's S-4000 series ecosystem. This unit serves a dual critical function: it acts as a signal splitter to distribute audio from a single digital stage box to multiple mixing consoles or recording devices, and it provides centralized power distribution for remote digital snake components. This capability is essential for complex live production scenarios such as broadcast, large-scale concerts, and theatrical performances where separate front-of-house, monitor, and broadcast mixes are required from the same set of stage inputs.

In its primary role as a digital splitter, the S-4000D accepts the digital audio stream from a connected stage box via a single Ethernet cable. It then cleanly splits and outputs this signal to multiple destinations—typically up to four separate digital mixing consoles or digital audio recorders—ensuring that each receiving device has access to all input channels with pristine quality and without any signal degradation or added noise associated with traditional analog splitting. This provides complete mix independence for different engineers while maintaining a single, streamlined cable run from the stage, significantly simplifying system infrastructure and improving reliability.

The unit's integrated power distribution system is equally vital, supplying stable, conditioned power to the remote digital stage box and other network components over the same Ethernet cable used for data transmission. This eliminates the need for a separate power cable run to the stage, further reducing setup complexity and potential points of failure. The S-4000D is built into a robust rackmount chassis, designed for continuous operation in demanding touring and installed environments. By combining clean, transparent signal splitting with reliable remote power delivery, the Roland S-4000D is an indispensable hub for building advanced, multi-console digital audio networks that are both powerful and elegantly simple in their execution.
