The Audio-Technica ATM350 is an instrument microphone designed for close mounting and capturing of brass, drums and percussion, reed instruments, piano, acoustic bass and more. The capsule features a cardioid polar pattern which minimizes noise and audio at the off-axis sections of the capsule.
The pattern is ideal while capturing drums and percussion, eliminating audio pick up from adjacent instruments. The attached UniMount microphone clip features a gooseneck style positioning for fast and accurate microphone placement. The ATM350 operates on battery or phantom power and features a 55" (139.7cm) long cable and 4-pin connector for attaching to UniPak wireless transmitters.
