Theater curtain (if used) should be opened fully, prior to making sound measurements. The

theater should be empty (except for the technicians) and no talking or extraneous noise should

occur during audio measurement.

The microphone should be aligned ‘straight up’ in a vertical position. Connect

the measurement microphone to the USB Preamp using a standard microphone

cable.

2. Attach the USB Preamp to the portable computer using the supplied USB cable.

3. Connect the USB Preamp to the laptop computer. Refer to Appendix A for

instructions for setting up the USB Preamp.

software.

The Dirac Live

software will not start unless the AP20 proxy software is already running.
