TOPIC

    I notice that after installing Mac OS 8.5 or later, I have options for both "External Microphone" and "Sound In" in the SoundSource Strip and the Monitors & Sound control panel. What is the difference between the two?

DISCUSSION

    Mac OS 8.1 gave you the option of using the external sound-in jack by selecting the "Sound In" option in the Control Strip or the Monitors & Sound control panel. However, the sound would play through to the speakers by default which could cause feedback when the external sound source was a microphone. Mac OS 8.5 and later, addresses that problem by offering an "External Microphone" source which uses the same sound-in jack, but turns speaker playthrough off by default.
