The JBL Commercial® CSPM series microphones are dynamic close-talking microphones for paging systems in bars/pubs, theatre lobbies, department store and more.

A single cable attached to the CSPM-4 contains three conductors for audio (Positive, Negative, Shield) and five conductors for contact closure (Zone 1, Zone 2, Zone 3, Zone 4, Ground). Selecting a zone and pressing and holding the PTT button will route the microphone audio to that zone.
