The S-4000H is also often used at Split positions providing 32 outputs of the Stage sources for monitor consoles, recording rooms or broadcast feeds. The Inputs and Outputs are provided on 8-channel 25 pin D-Sub connectors using the Tascam™ wiring standard. The audio is +4 line level and there are four 8-channel Output connectors and one 8-channel Input connector. There is a security bar provided with the system that allows an installer to secure the Input and Output cables. In addition, custom MASS® connectors are available for all channels or separately for Inputs and Outputs. Call Roland Systems Group at 1 800 380 2580 to order your custom cabling configurations. The redundant Ethernet connectors are rugged Neutrik Ethercon® connectors configured as Main and Backup. In case the Main cable is compromised, the system will automatically and seamlessly switch to the Backup cable and light an Indicator LED. In addition to redundant Ethernet connectors and an optional redundant power supply, the unit has a covered power switch to prevent accidental power loss. There is also a power cable security bracket. The S-4000H is rack mountable and provides flush or recessed mounting positions so a cover can be placed on its rack case while connectors are still in place. The S-4000H offers high quality line level Inputs and Outputs for Split or FOH locations along with Ethernet and optional power supply redundancy for a high quality, secure system.
