Was reading the following:
"In order to deliver its full frequency response, a ribbon microphone needs to see an input impedance of at least 4-5 times its output impedance. For example, if a microphone has an impedance of 300-Ohms, the preamplifier should have an input impedance of 1200 to 1500 Ohms, or greater"
Why would lower impedance input on the mic preamp attenuate frequencies? I'm assuming high frequencies are attenuated?
