Outline precisely masters the turntables

With the creation of the ET50-3D and ET250R2-3D, Outline has updated the ET Series of acoustic measurement devices. Since its initial launch, the computer-controlled turntable has been adopted by companies operating in a multitude of industry sectors in addition to universities and research institutes. In addition to microphones, loudspeaker systems and transducers, it is used to measure and calibrate mobile comms devices, antennae, solar panels, hearing aids, smart devices and domestic appliances.

The original concept of placing loads with perfect accuracy in a measurement environment has evolved as the two new models can suit different speed and load requirements. Features include an Ergal aluminium hardware design, which achieves mechanical resistance in addition to reducing the overall weight. A wider choice of rotation speeds is available with enhanced maximum handling loads and a user interface with an input-output communications port based on TTL signals. The network interface allows remote control accessibility, data acquisition and control via standard ethernet protocols.

Each turntable has an individual IP address for connection to an existing LAN for control via the provided software or one of several third-party measurement systems, including control libraries for Matlab and Python. This promotes automated polar measurements via seamless integration with various measurement software suites including Audio Precision, Audiomatica Clio, Listen Inc SoundCheck, Klippel, NTI and ARTA. The ET50-3D and ET250R2-3D models are capable of accurately orienting loads of up to 200kg and 1,000kg respectively.
