Outline ET2-ST2
the new version of its turntable
for measuring loudspeaker enclosures’ polar dispersion 

An enclosure’s polar response is a fundamental parameter when deciding on its suitability for any given application. Since 1990, Outline turntables have been used to measure the dispersion characteristics of the world’s best loudspeaker systems, designed by the most authoritative sound designers (see references). Although having the same dimensions as the previous model, the new ET2-ST2 version is even sturdier and offers the following new functions:

·          compatibility with all measurement systems on the market

·          minimum resolution of 2.5° per step 

·          total control via personal computer using ET Commander 3.3 software

·         a second (slave) turntable can be controlled by the same electronics and rotates in the   opposite direction to the main unit (useful among other things for running a rapid test of the acoustic coupling of two adjacent speaker enclosures)

·         two turntables can be controlled using two controllers and the movement synchronized using software for automatic 3D (balloon) polar plots.

The internal mechanism of the "ST2" has been considerably strengthened: the unit has an overturning moment of 30kg. and can now also be ceiling-mounted to hang loudspeaker enclosures weighing up to 100kg.

The motor rotating the unit  has 20% more power than the one mounted on the "ST1" and, for particular situations, a model with five times the power can be requested. A clutch has also been fitted to the motor in order to avoid damage in the event of use with extremely heavy enclosures.

The new ST2’s rotates in 2.5° "steps", and a different reading system has been adopted.
