The number of tabs depends on the entered channel number. The channel color can be changed by right mouse click.

Signal input

2. Signal input
Selects the used M302/M312 device and the inputs with connected microphones.
The gain setting determines the measuring range.

3. Frequency weighting
Selects the acoustical parameter to be measured. Besides the acronym the weighting and the time constant are indicated.
In the diagram RMS and peak values can be shown simultaneously. Peak values are indicated in brighter color on top of the RMS bars.
