The AR-70 STEREO includes one fixed cardioid capsule on the bottom, and on top, a capsule wired for remote multi-polar pattern capabilities. This allows the microphone to perform multiple stereo recording techniques, as well as a standard single channel monophonic recording, all in one package. In stereo mode, the AR-70 STEREO can be set up in a standard X/Y configuration, with each capsule orientated 90 degrees away from each other, resulting in a perfectly co-incidental pair.

With the option of the multi-pattern functionality of the top capsule, the microphone can also be used in Mid-Side (M/S) technique, where the lower capsule is fixed in cardioid, and the upper capsule is rotated 90 degrees and set to the Figure 8 polar pattern.

One of the most unique ways to use the AR-70 STEREO is in "dual mono" mode, which can lead to all kinds of interesting textures for vocals. By running the outputs into two different microphone pre-amplifiers, the user can now have one capsule set up to sound its best on quieter passages in a vocal and the other for louder passages. If the user runs about 10dB more gain on the microphone pre-amplifier for the capsule that is set up to record quiet passages, then both outputs can be recorded separately and blended later; or a compression device can be used on the pre-amplifier that is set up for the quieter passages which will net about 12-15dB of gain reduction as the singer gets louder. These two outputs can be summed and the resulting signal will maintain a relatively constant level while being automatically combined for optimal capture of the performance.

Each AR-70 Stereo microphone comes complete with M970AR power supply, M801 25' dual-shielded TX-7 tube microphone cable, M701 elastic shock mount, a FC70 locking flight case and wooden microphone box.
