Capture amplified vocals with a dynamic handheld microphone that combines a cardioid polar pattern with a 90 Hz–18 kHz frequency response. The cardioid pattern concentrates pickup toward the front of the microphone, helping place the performer ahead of stage monitors, instruments and ambient room sound. Its moving-coil dynamic element does not require phantom power, supporting direct connection to a standard microphone input. The AE4100 uses a balanced 3-pin XLRM output and a nominal 600-ohm output impedance for connection to mixing consoles, stage boxes, preamplifiers and installed sound systems. Its 177 mm handheld body and 48 mm maximum diameter provide a familiar vocal-microphone format for singers, presenters and spoken-word performers. A 310 g weight gives the microphone substantial handling without moving into a large-format stage body. Part number 153000-S2 identifies this dynamic cardioid vocal microphone configuration. It fits live sound deployments where a wired microphone path is preferred over a battery-powered wireless system, including fixed performance stages, rehearsal rooms and portable PA setups. The front-focused pickup pattern and balanced XLR connection make it appropriate for conventional analog microphone infrastructure as well as digital mixing systems with analog input stages.
