An audio device having a HDMI input port is provided to prevent malfunction by blocking a bidirectional clock communication line by applying a lower voltage than a constant voltage to a FET gate. An audio device with a HDMI input port includes a hot plug detecting unit. The hot plug detecting units(28,29) are installed In first and second HDMI input ports(20,25). If the preset specific device is connected to the HDIM input port, an FET is on by applying the constant voltage. If the arbitrary device which is not previously set is connected to the HDIM input port, the FET is off by applying the lower voltage than the constant voltage. If the preset player is connected to the HDIM input port, the hot plus detecting unit applies the constant voltage to a gate of the FET for turning on. |
