ANT Turntable

Computer controlled Loudspeaker Directivity Measurement System for Directivity Measurements

Loudspeaker Directivity Measurements

The ANT is a high-torque, ultra-flat turntable for automated loudspeaker measurements in combination with e.g. the measurement software WinMF. The turntable can stand weights up to 1000 kg (50 times its body weight) with a repeatability of the rotation below 0.1 degrees. To target a floor mounted microphone, the ANT can be tilted up to 4° using an optionally available accessory. Due to the compact integration of the heavy-duty ball bearing into the worm gear, the minimum height of the ANT is just about 80mm. The ANT is connected via RS485 and USB adapter to a personal computer or laptop.
