Streamline multi-zone audio distribution for AV, security and surveillance systems with the Radio Design Labs SF-TPRS12A line-level sender/receiver chassis. Designed for professional installations, this Home AV Receivers-class unit consolidates up to 24 audio channels (12 senders and 12 receivers) into a single, rack-friendly Format-A chassis—reducing panel clutter and simplifying cable runs for monitoring and security deployments. With balanced 4 dBu inputs and outputs and a frequency response up to 50 kHz, the SF-TPRS12A delivers clean, low-noise audio suitable for broadcast-quality monitoring and sensitive surveillance audio feeds. Local detachable terminal blocks make on-site wiring fast, while remote power over RJ45 and per-section green LEDs streamline module power distribution and status checks. Built-in wiring-fault protection with an automatic resetting fuse adds a layer of resilience for critical security and monitoring applications. Ideal for integrators, AV managers, and security professionals who need reliable, high-density audio interfacing, the SF-TPRS12A is an efficient solution for control rooms, surveillance hubs, and distributed audio projects. Specify the SF-TPRS12A for your next security or AV monitoring deployment and contact your distributor to order.
