Connecting External Devices Connecting Amplifiers or Other Equipment (OUTPUT [L/MONO], [R] jacks) Standard phone plug Connect a speaker with an internal amplifier to the OUTPUT jack. For mono sound, only connect the [L/MONO] jack. For stereo sound, connect both the [L/MONO] jack and the [R] jack. When an external device is connected, sound will no longer be produced by the instrument's speakers. CAUTION Make sure to turn off all devices when connecting external devices. Additionally, reduce the volume of each device to the minimum before turning the power on or off. Failure to do so may cause electric shock or damage the device. NOTICE When outputting sound from the instrument to an external device, first turn on the power to the instrument, and then turn the external device on. When turning the power off, follow the procedure in reverse order. Failure to do so may damage the device. Connecting a Microphone (MIC [INPUT] jack, MIC [GAIN] knob) Stereo mini phone plug Connect a commercially available external microphone to the MIC [INPUT] jack. Use a microphone with a stereo mini phone jack and plug-in power compatibility. Connecting an external microphone will automatically disable the internal microphone. NOTE When an external microphone is connected, the MIC [GAIN] knob controls the volume of the external microphone. 32 HD-300 Owner's Manual
