A - 628 for heart shape refers to the capacitive microphone pickup way, application in the studio, recording studios, broadcasting stations, stage performances and other professional situations. Cartridge parts using pure gold coating, with low noise. Gao Gan degree of output, and other functions, can be reproduced exactly extremely delicate voice, and be able to pick up the traditional microphone can't pick up the high frequency signal. Microphone with - 10 db attenuation and low frequency attenuation function, can easily deal with high input pressure source and low frequency background noise filtering stage, even under the high pressure stage environment, can maintain a clear print effect, not distortion, is particularly suited to fighting drums, guitar, such as sound recordings. Durable hard heat treatment of zinc alloy body and three layer network, can protect head to avoid accidental injury. And can reduce noise and call the sound. Ontology end connection using standard XLR connector (female), can match with all kinds of audio equipment, standard packaging for anti-collision pearl cotton, aluminum alloy box configuration has one microphone, phantom power supply box of a treasure, shock mounts a wind a sponge, equilibrium output line line one of audio, a black silk ribbon.
