Polarity

This menu allows you to analyze the speakers in your system and

determine which of them may be wired out of phase compared to the

others. For example, the posive and negave speaker cords may be

swapped on one speaker, giving rise to an audio cancellaon, most

noceable at the lower frequencies.

SPL Sound Pressure Level Meter

This display shows the measured Sound Pressure Level. This is very

useful in seng up a system and determining for example, that the SPL

does not reach unsafe levels that may cause hearing damage.

Menu items allow you to:

• Change the measurement weighng (unweighted, A, or C-weight-

ing)

• Reset the measurement

• Save and recall measurements

• Vary the measurement from fast, slow, impulse, peak

• Set the input

• Set the output
