Pendant Audio Without the Bulk

The C1511 is the compact member of the AXIS C15 series. It drops a 4-inch broadband speaker to listening height in shops, lobbies, cafeterias and open-ceiling offices where a larger pendant would dominate the room. The mesh can be repainted to match the ceiling, and wire length is set on site with the AXIS TC1901 Wire Kit.

Announcements, Paging and Music

Pre-configured DSP keeps speech intelligible across a 130° coaxial pattern, with a 70 Hz to 16 kHz response for background music. Combine live paging, scheduled messages and pre-recorded clips on microSD, and use content prioritization so emergency messages always cut through.

Smart, Open and Easy to Manage

The built-in microphone handles two-way audio and the auto speaker test. Two supervised I/Os connect buttons, PIR sensors or strobes, and the speaker works with AXIS Audio Manager Edge, Pro and Center, AXIS Camera Station, partner VMS, SIP telephony, and mass notification systems such as Singlewire InformaCast and Alertus.
