A test of 2 microphone arrays at 7 positions: 
    -115, -90, -45, 0, 45, 90, 115 degrees - 0 degrees being face forward.
                          
    AT4022 parallel spaced boundary array in 3 configurations:

    * AT4022 - 8.75" x 5.5" boundary, 1" inset
    * AT4022 - 8.75" x 5.5" boundary, 1" inset with a 6" high density uncoated foam ball
    * AT4022 - 5.5" x 4" boundary, 1" inset, 1" bevel
    * AT4022 - 5.5" x 4' boundary, 1" inset, 1" bevel with a 6" high density uncoated foam ball
    * MS MKH 30/40 pair using equal power decoding (1:1). 

    Both AT4022 mounts are spaced 6.875" apart.
    Two sounds are tested, a cello and pink noise.

    Speaker was distanced 45" from microphones. MS array was placed under the AT4022 array.
    All measurements approximate.

    Some noise from the outside is audible as is a refrigerator hum in some of the segments at approx -30 degrees from center (0 degrees).

Stereo Array Testing - AT4022 - MKH3040

A test of 2 microphone arrays at 7 positions: 
        -115, -90, -45, 0, 45, 90, 115 degrees - 0 degrees being face forward.

        MS MKH 30/40 pair using equal power decoding. 
        AT4022 parallel spaced boundary array in 3 configurations:
        * 3" inset
        * 1" inset
        * 1" inset with a high density foam ball

        In both recordings the order is MS, AT4022 with 3" inset, AT4022 with 1" inset, AT4022 with 1" and ball
