Microphones Heil Sound
The company Heil Sound (USA) manufactures microphones for music and vocal recordings in professional studio technology. And since the founder of the company, Bob Heil, is also a radio amateur, it was obvious to apply the experiences from the studio area also in amateur radio. Here, in contrast to music recording, it is not important to record unaltered over the largest possible frequency range. Rather, it is important to know the characteristics of human speech exactly and to take them into account. Thus, the frequency range that is important for good intelligibility is emphasized, while other ranges are rather attenuated.
Thus, the microphones and microphone capsules from Heil Sound are very well suited for radio technology, the intelligibility increases especially with noisy radio traffic on shortwave. Heil Sound offers a variety of precisely tuned adapter cables for trouble-free use with all leading radio equipment manufacturers, as well as accessories for microphone technology such as vibration-free suspensions, microphone booms, etc.
