Preamp Helps Identify Auto, Aero Noise Sources
Wednesday, September 27th, 2006The Model 426A11 is a 1/2” preamplifier that operates from ICP sensor power. Users can select 0 or +20 dB of gain and either a 20 Hz (-3dB) High Pass Filter or A-Weighted filter output response, in lieu of flat unfiltered response, via two switches, located on the external diameter. An overload detector senses both […]
