AtlasIED TSD-ZDC 4x4 Universal Impedance Divider Combiner, 150ohms I/O Connectors

Streamline audio distribution and signal management with the AtlasIED TSD-ZDC 4x4 universal impedance divider/combiner. Designed for professional integrators, this AtlasIED pro audio processor makes it easy to split or combine up to four channels while maintaining signal integrity for security, surveillance, monitoring, and AV systems. The passive unit features four 150Ω stereo I/O connectors plus four 10K stereo I/O connectors to accommodate a wide range of line-level sources and loads, and RF filtering on every input reduces interference for cleaner recordings and realtime monitoring. Because the TSD-ZDC requires no external power and includes removable I/O connectors, it installs quickly and stays reliable in control rooms, broadcast racks, or distributed network closets. Compact and lightweight, it’s ideal for government, medical, education, and house-of-worship projects where consistent audio performance and low maintenance are essential. Choose the TSD-ZDC to simplify wiring, improve audio clarity, and standardize deployments across multiple locations — add it to your next security or AV system spec.
