Description

The ALFC-657D are 2 x 30 watt full-range Dante ceiling speakers. It consists of a Dante Master speaker (ALFC-657DM) and a secondary Slave speaker (ALFC-657DS). The Master speaker contains a 2 channel POE amplifier connected via the Dante audio network and provides an amplified speaker output for the slave speaker. As each pair of ALFC-657D speakers are powered via the network POE switch, it makes it a convenient choice for distributed sound reinforcement solutions.
