Setting the Measurement Level

Setting the signal level the Wizard uses during measurement involves generating a pink noise calibration signal and adjusting the AV processor's volume control and/or the calibration signal level so that at the measurement point (usually ear height at your main listening position) your SPL meter shows a level of around 75dB.

Set Measurement Level Procedure

Press the button in the Signal Generator panel and follow the instructions on screen. The test signal is generated at an RMS Level of -20dB. If connected to an AV processor, start with the volume fairly low and increase it until the meter is reading around 75dB. The exact level is not critical. If connecting directly to an equaliser such as the BFD, use the control the Wizard provides during the setting process to change the level of the generated signal. In either case, the final signal generator level will be used for subsequent measurements - remember to use the same AV processor volume setting whenever measurements are made.

Note that the measurement level can be altered manually by changing the value in the Measurement Level box above the button.

After setting the Measurement Level the next step is to set the input volume control.
