A monitor system has at least first and second child units that can each monitor audio at a different location and can each transmit signals representative of the audio monitored. A parent unit can receive the signals from the first and second child units. In one aspect, the parent unit can have at least one multi-color notification light that can be illuminated in a first color when receiving the audio monitored by the first child unit and a second color different from the first color when receiving the audio monitored by the second child unit. In another aspect, the parent unit can emit an audible notification representing the audio monitored by each of the child units. In this aspect, a volume control is in communication with the parent unit and can be operated to adjust a volume level of the emitted audible notification for each of the child units independent of the other child units. In yet another aspect, the parent unit can emit a notification representing each of the signals and can sequentially listen for the first child unit for a first duration and at least the second child unit for a second duration during a listening cycle. In this aspect, the parent unit can continuously repeat the listening cycle and the first and second durations can be adjusted by a user to a different duration selected from a plurality of different duration options.
