  • Q & A

    Is it okay to keep the 4081 stored on its side for a long period of time? I have it set up on its side ona stand by my piano & I prefer not to move it

    Jamal

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

    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.

    DSatz

    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.
