Heil Sound GM-4 Microphones are unique, innovative microphones renowned for their gorgeous audio production. Their crystal-clear response made them the microphones of choice in thousands of ham shacks around the world today.
GM-4 full-range microphones have two dynamic elements, allowing an instantaneous change for different types of operations. Their two-position switch labeled WIDE/NARROW selects one of the two dynamic elements. Choose the WIDE full-range broadcast element to use with your rig's internal or external equalization, perfect for high fidelity ESSB operations. Switch to the NARROW HC-4 DX Dream Machine element with accentuated highs and restricted lows for that extra punch to bust that pileup.
GM-4 Microphones included the Heil-exclusive "Light Touch" PTT switch and are encased in a beautifully finished high-gloss black lacquer enclosure. They are fitted with a 4-pin XLR connector that's compatible with the Heil CC-1 Series of adapter cables. The GM Series microphones are shipped with a foam windscreen and the industry standard 5/8 -27 threaded microphone clip.
