Using balanced-line low-impedance cables permits very long cable lengths without af- fecting response or level. The RED and BLACK cable leads are the microphone conductors for balanced-line connections the shield is connected to the amplifier ground. For unbalanced operation, connect the BLACK lead to the shield, and use the RED lead as the microphone conductor. SHURE Incorporated
