12.6.2 PREPARING THE TURNTABLE
Open the Turntables Control dialog and select the connected turntable (See 4.7).
Outline ET/ST (TTL Pulse)
We assume that the Outline ET/ST turntable is properly connected to your PC
(refer to 4.7.1 for details). To prepare for this measurement session you need
to:
1) Manually set the front selector labeled 'Deg Step' to 5°.
2) Rotate the turntable counterclockwise until you reach the desired start
position: as we want to start from -180° position it at 180°.
3) Recall the Turntable Settings dialog (Fig.12.12), set Resolution at 5°, Speed
at 0.75 RPM
Figure 12.12
In order to link the TTL pulse generation to measurements leave the
Turntables Control dialog open during the measurements.
Outline ET250-3D or LinearX LT360
We assume the turntable is properly connected to your PC (refer to 4.7.1 for
details). To prepare this measurement session you need to:
1) Set the turntable step to 5° using the turntable specific supplied software or
turntable panel hardware controls
2) Rotate the turntable counterclockwise until you reach the desired start
position: as we want to start from -180° position it at 180°.
In order to link the turntables to measurements leave the Turntables
Control dialog open and the turntable linked during the measurements.
12.6.3 TAKING THE MEASUREMENTS
You are now ready to begin the measuring session. We suggest you to take an
initial measurement (with the speaker in place over the turntable) to verify all the
parameters, especially viewing the acquired impulse response and setting the start
and stop values of the measurement window. These values will be applied to all the
measurements taken; consider, in this respect, the problem of the trajectory of the
acoustic center of the speaker during the rotation.
