100Vrms supervised speaker output
In the case of a supervised line, this presents an additional tone of 20kHz, for impedance measurement.
The IAS-ADAPT module provides, by inserting a jumper (
paragraph 3.21 - [E]
,
paragraph 3.21 - [F]
), a filter to eliminate the
supervision tone from the audio output.

IFAMAMP internal module wiring
This paragraph illustrates the wiring possibilities via the IFAMAMP module, necessary for the connection for speaker lines
driven with a maximum signal of 100 Vrms.
Note:
The sum of the power of all the speakers connected to the module must be less than or equal to 250W.

Cables:
2 pole cable as per the reference standard
EN IEC 62368-1:
