It is safe to connect most modern dynamic microphones or line level devices to the channel inputs when phantom power is
activated. However, some older ribbon microphones may be damaged by phantom power, and certain unbalanced line level devices may
malfunction or produce an audible hum when phantom power is active. Consult the documentation for these devices if you are unsure
how to proceed.
