IFAMAMP

250W audio amplifier module

The 250W IFAMAMP audio amplifier module provides two lines for speaker connection configurable in A/B mode or in Loop mode, each line individually protected from short circuit. 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. Automatic management of any backup amplifier included in the cabinet. Each control panel manages a maximum of 30 IFAMAMP modules (maximum 8 for each cabinet).
