RDL ST-RX2 Audio Routing Switcher, 1x2

Route a single line-level audio source to two destinations reliably and silently — ideal for security, surveillance, paging and AV monitoring applications. The Radio Design Labs ST-RX2 1x2 Audio Routing Switcher uses solid-state switching and soft-mute circuitry to eliminate clicks and pops, delivering professional, uninterrupted audio. With one line-level input and two balanced line-level outputs, the ST-RX2 supports balanced or unbalanced connections and feeds two line drivers while maintaining off attenuation better than 80 dB for excellent channel isolation.

Control requires less than 0.5 mA at the TRIG terminal, so you can switch outputs with simple switches, open-collector logic, or RDL remotes (D-RC2ST/D-RT2). Because there are no mechanical relays, the module provides long-term reliability in security and monitoring systems where uptime matters. Housed in a compact package and made in the US, the ST-RX2 is engineered for integration into surveillance, access control, and AV distribution racks. Add the ST-RX2 to your system today to simplify audio routing and improve signal integrity in critical monitoring environments.
