The CXO4000 Compact XY/ORTF Stereo Holder is designed to mount a DPA pencil microphone with MMP-ER/ES or MMP-GR/GS preamplifiers in both a coincident XY stereo configuration as well as in a near-coincident ORTF combined time and intensity difference stereo configuration. 

Two hooks in the middle of the stereo holder are for XY stereo, while the two on the side are for ORTF stereo. You can use both stereo setups simultaneously in order to compare in the editing process or use the holder to record in surround sound using one front and one back-orientated stereo setup.

The holder is made of black-anodized aluminum and ethyl propylene rubber rings to ensure durability and stability. For flexibility, the holder also includes a thread adapter for attachment to most common microphone stands.

In order to receive an authentic reproduction of the total sound field (direct and ambient sound elements) it is extremely important to use microphones that have a linear and clean off-axis response. Likewise, it is critical to use two microphones that are, within a narrow tolerance, identical in frequency response and sensitivity.
