The ART T4 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 T4 ideal for virtually every recording application. The microphone's chassis is precision-tooled brass body with a dent resistant stainless-steel wire-mesh windscreen protects the dual 35mm gold sputtered diaphragms and integrated 7025 vacuum tube pre-amp. An external heavy-duty cradle mount suspension virtually eliminates vibration and handling noise. The T4 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 T4 has three gradient stages between each of those positions allowing the artist and recording engineer a wider tone pallet.
