Abstract (en)
[origin: US7366308B1] The invention relates to a sound recording device for a public address system. Sound is emitted from a sound source, picked up by at least two sound sensors and converted into electrical signals. The sound sensors are located at a distance from a reference position which corresponds to an ideal set position. Directional vectors located between said reference position and the sound sensors indicate different directions. The sound sensors are electrically or acoustically connected to a common signal amplitude add device.
