LEM Commercial - DMF-iAMP2300

The DMF-iAMP2300 is a 300 W per channel mixer / amplifier with a built-in media player, designed for commercial applications requiring high audio quality, reliability and maximum versatility.

It features two priority microphone inputs, two AUX inputs, a media player with USB / BT and recording function, as well as an auxiliary output and two independent amplifier channels with volume, bass, and treble controls. The output can be configured in mono or stereo mode (TWO independent MONO channel operation or ONE channel for stereo music / announcement) and supports both low impedance loudspeakers (4 / 8 ohms) and 70/100 V constant voltage lines, making it compatible with any commercial PA system.

In this Wi-Fi version, it allows audio streaming via a local network, supporting protocols such as DLNA, AirPlay, and Spotify Connect, as well as multi-room management via a dedicated App. This integration allows you to send audio content from a smartphone, tablet, or PC without additional wiring.

The DMF-iAMP2300 includes advanced features such as a chime (warning signal), siren (audible alarm), dry contact emergency message management, a 24 V_DC output for paging, and an LCD display showing status, playback mode, and internal PCB temperature.

Thanks to the completely fanless design, operation is silent and suitable for environments where background noise must be kept to a minimum.
