Portable minirack, four‑module enclosure designed to hold CST36 transmitter module, CSR50/CSR35 receivers, and PSS26/PSS23 power supplies. It provides dedicated bays for the three module types in a compact, transportable 4‑module rack for modular wireless systems in live environments. The brochure documents rooms for modules but does not provide operating, frequency, audio, or electrical specifications. The design supports standard 19‑inch rack infrastructure for field use.
