    ACCESS/A A711 L-Series Installation & Operating Instructions 09RE416 MICROPHONE INSTALLATION All microphone connections to the A711L must be done with shielded cables. The inputs are intended for use with standard “carbon-equivalent” or amplified dynamic Microphones (such as the D/C M1, M4 M7, etc.). Shielded, twisted pair routing is strongly preferred for lowest noise pick-up, but single conductor shielded wiring generally gives adequate results in non-critical or single box installations, although noise floor and cross-talk will increase.
