A USB port makes firmware updates possible in the field.
The HMa combines 24-bit digital audio with analog FM transmission resulting in superior radio reliability with superb audio performance. Audio frequency response of the HMa is stated at 40 to 20k Hz plus/minus 1 dB. Phantom power is selectable at 5, 15 and 48 volts, or can be turned off for use with dynamic microphones and line-level signal sources.
