RDL SF-TPS24A Line-Level Sender, Separate Three-Pair Format-A Sender Sections

Optimize audio distribution for AV, security and surveillance installations with the Radio Design Labs SF-TPS24A line-level sender. Designed as a compact sender chassis, the SF-TPS24A converts and transmits up to 24 balanced line-level channels over Format-A twisted-pair cabling, simplifying wiring for multiroom AV, monitoring stations, and surveillance audio feeds. Each of the eight independent three-pair sections accepts three +4 dBu balanced inputs on removable terminal blocks and feeds pairs A, B and C of the associated RJ45 output, allowing clear separation of sources and straightforward zone management. With a wide frequency response up to 50 kHz and local power distribution that feeds connected modules, the chassis supports high-fidelity audio and reliable remote powering for critical security hardware. Built-in wiring-fault protection and per-section LEDs for power validity reduce troubleshooting time during installation. Ideal for integrators and system designers who need dense, professional audio distribution over standard twisted-pair cabling—deploy the SF-TPS24A for centralized audio routing in surveillance, monitoring, and commercial AV systems. Contact your sales representative to specify the SF-TPS24A for your next security or AV deployment.

• Simplifies multiroom audio and security audio routing by sending up to 24 balanced line-level channels over Format-A twisted-pair cabling
• Eight independent three-pair sections let you isolate and manage sources per zone for cleaner monitoring and surveillance feeds
• Three +4 dBu balanced inputs per section on detachable terminal blocks enable fast field wiring and integration with existing AV or security gear
• Utilizes all three Format-A pairs with RJ45 outputs to maximize channel density and reduce cabling cost in networking and monitoring installations
• Local power distribution and automatic-reset fuse protection maintain uptime and protect downstream modules in critical security and surveillance systems
