ThePioneer CU‑MR100 is typically associated with Pioneer MCACC‑enabled AV receivers, such as certain VSX‑1000K, VSX‑909, and similar early‑to‑mid‑2000s Pioneer receivers. It is also compatible with thePioneer MR‑100 Remote Zone 2 Sensor for second‑zone or remote‑sensor installations, which expands its utility beyond single‑room systems.
