The sE Electronics IRF2 Instrument Reflection Filter is a smaller version of the larger Reflection Filter. The IRF2 Instrument Reflection Filter is ideally suited for isolating small diaphragm microphones while capturing instruments, vocals and more. The filter is designed with a curved, punched-aluminum frame and 3 layers of polyester fiberboard. The fiberboard layers are floated with gaps between each layer to minimize noise transference and ensure high isolation. Also included is an adjustable gooseneck for flexible positioning and control.
