An evolution of the previous Hi-Sound Mono Parabolic Microphone, the Hi-Sound Mono EVO Parabolic Microphones capture sounds with two or four high-quality electret AOM sensors. It utilises a single output to improve the sound saturation and provides higher sensitivity and is available with either XLR or 3.5mm jack connections.
The 2x AOM model has excellent directivity and sensitivity and is ideal for bird song.
The 2 extra sensors in the 4x AOM model increase the sensitivity by around 3 dB making this model a good choice for nocturnal bird migration monitoring.
Hi-sound systems include handle, microphone and disc. The only additional equipment needed is a compatible recorder. The recorder must support PIP plug-in power if it uses a 3.5mm jack and phantom power if it uses an XLR lead.
