This has been around for a little while already, but it’s definitely worth mentioning again. Meet the DPA CXO4000 stereo mount, a superb little solution for mounting mics in ORTF or X-Y configurations.
We’ve had plenty of experience using this with the d:dicate™ 4011ER cardioid mics, for things like drum overheads (ORTF), acoustic guitar (XY) and orchestral ensemble recordings (ORTF), with excellent results. It’s a lightweight and durable little clip, measuring only 140mm across and weighing in at just a few grams. The Two hooks in the middle of the stereo holder are configured perfectly for XY stereo positioning of the mics, while the two hooks on the side are configured for ORTF stereo positioning.
Obviously, due to the compact size and fastening method, the CXO4000 stereo mount has been designed primarily for DPA’s MMP-E active cables, though could also easily support the MMP-C preamp as producer ELY recently experienced using two CXO4000 / ST4015C configurations in X-Y to record two drummers simultaneously at Red Bull Studios in London.

It is even possible to use both stereo setups simultaneously so that you can compare the two methods later in the editing process. Thinking laterally, you can also use two CXO4000 holders to record in surround sound using one front and one back-orientated stereo setup.
ORTF Stereo Miking Technique
ORTF stands for “Office de Radiodiffusion Télévision Française”, where this stereo miking technique was developed around 1960, and involves spacing a pair of matched capsules 17cm apart at an angle of 110°. This provides an incredibly realistic stereo recording of the source, while maintaining good off-axis rejection as it’s primarily used with cardioid capsules. The relative distance of the capsules simulates what we hear naturally with an average distance between our ears of around 20cm.

XY Stereo Miking Technique
XY stereo miking technique involves arranging two directional microphones with their capsules placed coincident and angled at 90° to each other. This technique is most commonly used for close miking situations as the close placement of the capsules results in fewer phase problems caused by sound arriving at the capsules at different times. Taking this into account, the XY configuration allows you to practically handle the pair of mics as one and produce excellent stereo recordings.
