[Problem] To enable the response audio of one transceiver to be heard by other transceivers, in cases when a plurality of subordinate transceivers (slave devices) are present. [Solution] A relay device is provided with: a wireless interface having a repeater connected thereto; a signal processing unit connected to the wireless interface; a network interface connected to a network; a packet processing unit connected to the network interface; and a mixing unit provided between the signal processing unit and the packet processing unit. The packet processing unit reads an audio signal from a packet inputted from the network interface, and outputs the audio signal as a downlink audio signal. The mixing unit inputs the downlink audio signal into the signal processing unit, and inputs an uplink audio signal into the signal processing unit. The signal processing unit outputs, to the wireless interface, the downlink audio signal and the uplink audio signal. |
