Its frequency response runs from 120 Hz to 16 kHz, its maximum sound pressure level is 122 dB SPL, and its signal-to-noise ratio is 86 dB. The sensitivity is 0 dBV/Pa, which equals 94 dB SPL at 1 kHz. The microphone includes one internal channel for acoustic echo cancellation (AEC). Typical power draw is 5.7 W and rated power is 9 W. The unit operates between 0 and 50 °C at 5% to 90% humidity.

Mount the CM20 in the ceiling of a conference room and power it over its single RJ-45 port using PoE (IEEE 802.3af, Class 3), so no separate power supply is needed at the ceiling. The microphone weighs 615 g and has an ABS and PC housing with an iron mesh cover in pearl light gray. Procure.ae can advise on placement and cabling for your room before installation.
