Overview

The APE30RS, a Ø30 mm sphere, gives a mild modification of your microphone's on-axis and off-axis frequency responses and a slight change in the direction-to-reverberation ratio. This will give your recordings greater presence, nearness and clarity on-axis (especially around 4 kHz).

An on-axis boost, between 2 kHz and 8 kHz, and high-frequency roll-off off-axis, will sometimes help you capture the subtle audible details of both musical instruments and voices.
