Developed in conjunction with


The ART M-Four tube condenser microphone is perfect for recording both critical vocals and essential instruments. The dual diaphragm multi-pattern tube design delivers nine different polar pattern settings allowing unmatched versatility, making the M-Four ideal for virtually every recording application.

The microphone's chassis is precision-tooled zinc/aluminum alloy with a dent resistant stainless-steel wire-mesh windscreen protects the dual gold sputtered diaphragms and integrated 12AX7 vacuum tube pre-amp. An external heavy-duty cradle mount suspension virtually eliminates vibration and handling noise.

Low Noise External Power Supply
The ART M-Four has nine available polar patterns, selectable from the front panel of the external power supply unit. Rather than limiting the user to only the three most common patterns (omnidirectional, cardioid, and figure-8 patterns), the ART M-Four has three gradient stages between each of those positions allowing the artist and recording engineer a wider tone pallet. For example, in vocal applications where an omnidirectional pattern isn't quite 'fat' enough, but cardioid is too narrow, you now have three additional steps to find the right subtle mix between those two standard patterns. With the ART M-Four you have the rare opportunity to use the proximity effect of a cardioid, yet still open up the microphone to hear some of the natural early reflections of a good sounding live room.

The included heavy-duty cradle-mount suspension virtually eliminates vibration and handling noise, while at the same time safely securing the microphone in any position needed during the recording process.
