Table 2. Total Power Consumption by Microphone Count and ActivityThis table shows the power consumption of the entire SMART System based on the number of active microphones and whether the microphones' heaters are active. The power consumption measurements shown here are approximate and will vary on factors such as attached peripherals, CPU load, and system configuration.
Activity No Mics One Mic Two Mics Three Mics
Powered down 0.6 W 0.6 W 0.6 W 0.6 W
Idle, powering mics via PoE 6.4 W 8.4 W 10.4 W N/A
Analyzing and/or recording audio N/A 9.5 W 12.2 W 14.5 W1
