Using the coupler provided, the test signal can be applied to either ½-inch or ¼-inch microphones, or picked up from an electrical output. For ease of use, Type 4226 can also apply a very accurate inverse A-weighting correction.
An external generator can be connected to Type 4226 if a frequency sweep or semi-automatic test is desired.
