The microphone element sits on top of a straight 11.8-inch aluminum stem with a silver anodized finish, mounted to the glass partition so the pickup head extends through the glass to mouth height on the customer side. At 1.10 pounds, the M14-300 is roughly three times the weight of Contacta's lighter curved-tubing STS-M14-BENT variant because the stem is purpose-built for rugged service rather than for aesthetic styling.\u003c\/p\u003e\n\u003cp\u003eThe anti-vandal positioning matters at service windows exposed to the public where a customer-side microphone can take abuse: supermarket checkouts, government building service counters, public transit fare booths, airport check-in and information desks, and any high-traffic customer-facing counter where a lighter microphone would be at risk of being bent, broken, or torn out. The aluminum stem and anodized finish resist denting, chipping, and corrosion in high-traffic public environments, and the uni-directional cardioid pickup pattern rejects ambient lobby noise from the sides and rear so the customer's voice gets through to the staff side clearly even in loud spaces.\u003c\/p\u003e\n\u003cp\u003eThe cardioid directional microphone picks up the customer's voice from directly in front of the microphone head and rejects sound from the sides and rear. That is specifically important in high ambient noise environments where multiple customers may be queued at adjacent service positions, HVAC and refrigeration systems add constant background noise, or lobby PA announcements compete with the counter conversation. The microphone's 100 Hz to 5 kHz frequency response covers the full intelligibility range for speech without wasting sensitivity on sub-bass or ultrasonic frequencies that don't carry useful voice information.\u003c\/p\u003e\n\u003cp\u003eTechnical specs: cardioid directional response, -47 ±3 dB sensitivity at 1 kHz, 680-ohm output impedance at 1 kHz.
