Capture vocal performances with a handheld condenser microphone using a cardioid pickup pattern. The AE5400 format combines a stage-oriented handheld body with condenser transducer technology, making it relevant where a performer holds the microphone rather than using a fixed, stand-mounted installation. Its cardioid characteristic provides directional pickup for vocal work and fits live sound, rehearsal rooms, and spoken-performance setups. This form factor keeps the microphone at the performer position during use. Ordering code 157000-01 corresponds to the AE5400 designation. The stated product characteristics provide three core selection points: handheld form factor, condenser operation, and a cardioid pattern. Those details distinguish it from microphones selected primarily for broad-area pickup, instrument placement, or permanently installed audio positions. Match the directional pattern and handheld use case to the intended vocal-microphone role. Use the AE5400 designation when selecting supporting stands, cables, clips, and audio-input equipment. The established microphone characteristics are its handheld vocal role, condenser construction, and cardioid pickup pattern. These attributes support applications where the performer needs direct control of microphone position and where a directional vocal microphone is required within the audio setup.
