CCLD, A-weighted microphone preamplifier

Type 2699 uses a built-in, A-weighting filter to eliminate low-frequency disturbance caused by body boom and road noise which would otherwise be a source of error during in-car measurements. Its robust, compact design means that you can use Type 2699 in a wide range of environmental conditions.
