JBL SDP-75 - Measurement Microphone

151
19.8 3D MEASUREMENT MICROPHONE
The purpose of the calibration microphone is to measure
the characteristics of the loudspeaker and their layout in
the room.
For each loudspeaker, the Optimizer gathers the following
information:
• full 3D position
• amplitude response
• phase response
NOTE: Another quite popular pinout is the one from Yamaha. You should check which pinout
your equipment is using before connecting it to the SDP-75. Unbalanced connections must
connect signal to SubD-Hot and shield to SubD-Cold.
