Active dynamic microphone optimized for use with instruments. Handcrafted in Vienna and subjected to the strictest quality control processes. “Swivel Joint” suspension mechanism allows 220° rotation of the field to precisely align the microphone with the sound source or according to personal sonic preferences without having to uncomfortably adjust or loosen the microphone stand. Precise directionality thanks to the Austrian Audio's Open Acoustics technology that also allows subsequent sound to pass through the capsule, resulting in an extremely precise cardioid characteristic. Called "linear cardioid" by Austrian Audio, this directional pattern ensures that the sound arriving is not not only from the front, but also from the back or the sides, sound good and without distortion. This ensures that even the sometimes inevitable crosstalk from other instruments sounds good. Active dynamic circuit that ensures that even long cable runs do not have an effect negative in the signal CAB filter ("Cut & Boost") at 80 Hz, especially suitable for use with guitar amplifiers, for example, which eliminates unusable low frequency sound and at the same time captures the pressure of useful signal in the bass range and at 120 Hz is a common 2nd order high pass filter. Pad switch that, in the zero position, allows a sensitivity usually found in condenser microphones, making it almost impossible for the OD5 to saturate.
