The Roland SC-W100S is a specialized, high-performance digital audio cable designed exclusively for use with Roland's REAC (Roland Ethernet Audio Communication) protocol. This 100-meter cable serves as the critical physical link in a REAC network, connecting a digital mixing console to a remote stage box or linking multiple REAC devices in a daisy-chain topology. The cable is engineered to meet the rigorous demands of professional audio networking, where it must reliably transmit hundreds of channels of uncompressed, low-latency digital audio, along with control data and clock synchronization, over long distances. Its construction is specifically optimized to maintain signal integrity for the high-frequency data transmission required by REAC, preventing data errors, dropouts, or synchronization issues that can occur with standard, off-the-shelf Ethernet cables.

The cable features high-quality, shielded twisted-pair conductors and robust RJ45 connectors with metal shells. This shielding is paramount for rejecting electromagnetic interference (EMI) and radio frequency interference (RFI), which are common in environments packed with lighting rigs, power cables, and other digital equipment. The connectors are designed for a secure, locking fit to prevent accidental disconnection, a vital feature in live performance situations. The cable jacket is durable and flexible, resistant to abrasion and crushing, making it suitable for permanent installation in conduit or for careful deployment on touring stages where it may be walked over or coiled repeatedly.

For any system relying on Roland's REAC technology—such as the M-48 personal mixer ecosystem or digital mixers like the Roland M-5000—the SC-W100S is an essential infrastructure component. It provides the assurance that the digital audio backbone of the system is built with cable that meets or exceeds the manufacturer's specifications for performance and reliability. Using this dedicated cable eliminates a potential point of failure, ensuring that the complex digital audio network operates with the stability and fidelity required for critical professional applications.
