Members Art Flood Posted November 21, 2013 Members Share Posted November 21, 2013 Does amplifier input sensitivity just mean by how much the attenuators can reduce the input signal?My power amps have an input sensitivity of +8dBu. If 8dBu is 1.95 volts, then they can pad the input signal by 1.95 volts.No real point to my question other than being curious and struggling to think in dBs (voltages I can work with).Cheers Link to comment Share on other sites More sharing options...
Members agedhorse Posted November 21, 2013 Members Share Posted November 21, 2013 Nope. What input sensitivity means is the required drive signal level to drive the amp to rated output. If the input sensitivity is +8dBu, that means that 1.96V (RMS) is required toachieve the rated powe of the amp. The attenuators can reduce the sensitivity by increasing the required drive level.

Members Art Flood Posted November 21, 2013 Author Members Share Posted November 21, 2013 Thanks AH. That makes more sense.I note my mixer has a max output level of +21dBu. This seems quite a mismatch to the amplifier.Is this typical?Thanks Link to comment Share on other sites More sharing options...
