Beta 58a SC2-CP and SC4-CP
The identifiers SC2-CP and SC4-CP relate to components of the older, now discontinued, Shure SC Wireless System.
SC2 and SC4: These were the model numbers for specific components in the system:
SC2 was likely a handheld wireless transmitter that could be fitted with various microphone capsules, including the Beta 58A capsule.
SC4 was the associated diversity receiver unit for the wireless system.
CP Suffix: The "-CP" suffix likely denoted the specific frequency band (e.g., 196.600 MHz) in which the components operated. Shure used various frequency codes (like CP, CL, CF, AA) for different regions or frequency allocations at the time.
