These?AMT B811?microphones are a matched pair of cardioid condenser mics suited for capturing drum overheads, stereo ambience, piano, and more. When used in pairs, the microphones accentuate cymbals accurately, while the cardioid pattern allows for a good rejection rate outside the perimeter. The B811 operates on phantom power from 15 to 48 volts DC and an LED indicates status of power (on/off and voltage). Transformerless circuitry gives the mic a transparent sonic character while the flat frequency response allows for a wide array of applications and the 0.5″ diaphragm allows the mic to fit into small spaces. The B811 is AMT’s stereo drum overhead solution and can also be used on piano, violin, guitar, woodwinds, brass, and more.Stereo Matched The B811 system features a stereo matched pair of condenser microphones for cymbals, stereo ambiance, stereo piano, etc. Cardioid Polar PatternThe cardioid Polar pattern minimizes off-axis noise.Rugged ConstructionIts rugged construction of anodized aviation aluminum allows it to withstand high impact, while being sleek, durable, lightweight and non-corrosive.
