IP Speaker Module The IPSM-1C40 / IPSM-1C40M module is equipped with 40W x 1CH high efficiency Class-D amp board into 4 ohm loudspeaker with PoE+ power (and/or 24VDC power supply if POE+ is not available). With Power over Ethernet (PoE+) technology, both audio control and power can be flowed over the standard female RJ45 Ethernet connector, giving a cost effective way to be used as the SIP endpoint of paging, intercom, PA/VA system and minimizing the number of cables.
IPSM Series

The IPSM-1C40M comes with a microphone input built-in, allowing for hands-free intercom. The PSM-1C40 / IPSM-1C40M has 3 control inputs for level control using RAC remote device, 1 contact output for triggering events via TerraManager and a clock module interface for connecting to time clock display.

The remarkable features include paging, intercom, music streaming, routing, priority management, event management, volume control, AEC (Acoustic echo cancellation), NR (Noise Reduction), logic control, monitoring etc..
