I'm looking for a directional (off-axis rejection) microphone with flat frequency response. The Shure SM81 is the only such mic that I've been able to find online, however its frequency response chart has multiple lines and I don't know what that means?
From Shure SM81 spec sheet pdf
The response curves are for each of the three selectable roll-off switch positions...
From the spec sheet -
Low Frequency Response Switch Positions
Flat; –6 dB/octave below 100 Hz; –18 dB/octave below 80 Hz
