Why you need the Crown CM311AESH Headset Microphone
Designed for touring and live-sound applications, the Crown CM-311AESH is a rugged head-worn microphone with unequaled performance. It sounds like the best handheld microphones full, clear, and distortion-free, even with the loudest singers. The CM-311AESH is the latest version of Crown's proprietary Differoid technology. Its cardioid pickup pattern rejects sounds from the rear, such as floor monitors. Its noise-canceling ability rejects sounds at a distance, such as instruments on stage and crowd noise. This results in the CM-311AESH having outstanding gain-before-feedback and isolation.
Features
- Full, clear, distortion-free sound
- Outstanding gain-before-feedback and isolation
- Connects to most wireless transmitters
- Transducer type: Electret condenser.
- Frequency response (typical): 50 Hz to 17,000 Hz
- Polar pattern: Cardioid
- Impedance: 6 kilohms unbalanced.
- Recommended load impedance: 10 kilohms
- Open-circuit sensitivity, typical, close-talking: CM-311AE, 1.25 mV/Pa (”58 dB re 1V/Pa).
- Power sensitivity, typical, close-talking: ”71.5 dB re 1 mW/Pa.
- Equivalent noise level (self noise): 26 dB SPL typical (0 dB = 0.0002 dyne/cm2), A-weighted.
- S/N ratio: 68 dB at 94 dB SPL.
- Maximum SPL: 140 dB SPL with 3V DC, 148 dB
- SPL with 9V DC.
- Operating voltage: 3”9V DC from the transmitter's battery.
- Polarity: Positive pressure on diaphragm produces positive voltage on shield with respect to white lead.
- Current drain: 0.27 mA nominal.
- Off-attenuation: 70 dB.
- Output connectors: supply your own to match your transmitter.

- Materials: High-impact plastic mic housing, brass boom, steel wire headband
- Net weight: Head-worn mic, 2.1 oz (61 g)
- Dimensions: Headband 5.5-in. (13.97 cm) diameter, adjustable. Boom approximately 7 in. (17.78 cm) x 3 in. (7.62 cm). See Figs. 3 and 4.
- Included accessories: Microphone carrying case, WS-6 foam pop filter, clothing clip.
