IFAMAMP, audio amplifier module
The IFMAMP audio amplifier module provides two lines for connecting speakers, configurable in A B mode or in loop
mode, each line at 100Vrms, individually protected from short circuits and with a maximum of 250W of power supplied.
The impedance of the speaker line is supervised by a high frequency tone. Includes an analogue input for an audio
source with adjustable priority for the amplifier line only.
IFMAMP can manage any other amplifier module, in backup function, included in the cabinet.
Each control panel manages a maximum of 30 IFAMAMP modules (maximum 8 for each cabinet).
IFAMAMP comes with:
• 3 screws for securing the module to the grounding bar
• 2 ferrites
• Instructions manual
