        Thank you for your inquiry. According to our engineers, it is not necessary to store the AT4081 vertically.

    • Q:

      Low frequency response of AT4081

      Hello. Your frequency response curve for the AT4081 is labeled: 12" or more on axis. Unfortunately I'm not sure what that means. Does the curve show the microphone's performance at 12"? If so, how much is the low-frequency response influenced by proximity effect? What would it be at, say, one meter? Many thanks.

      • A:

        Thank you for your inquiry. The curve as shown is measured at ½ meter (19.685”). I would say the curve represents the performance at 12 – 20 inches. Beyond that, at a meter, I would expect some decrease in low frequency.
