CSPM-2 (discontinued)

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

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