What is the input sensitivity of ICEpower modules?

You can calculate from the maximum output power and amplifier gain. Input sensitivity = Output voltage at the max output power / amplifier gain

For example: 125ASX2 (SE mode)

Quote from the datasheet of the 125ASX2:

General Audio Specifications (se mode)

General Audio Specifications (se mode) 2

 

If we want to calculate Input sensitivity for 120W into 4Ω:

√(120W x 4Ω) / 24.8dB = 1.26Vrms
