The headphone amplifiers on the Raspberry Pi DAC boards can drive up to 80/90Ω impedance headphones. Aux in:: A double Phono/RCA connector or 3.5mm socket. Accepts analogue audio in up to 1V RMS. This can be used to record audio from a variable analogue source such as a mobile phone, MP3 player or similar. Aux out:: A double Phono/RCA connector or 3.5mm socket. Delivers analogue audio out up to 1V RMS. This can be used to feed audio into an amplifier at a reduced volume compared to Line out. Ext mic:: A 3.5mm socket for use with an external electret microphone. The built-in MEMS microphone on the Codec Zero is automatically disabled when the external Mic in connector is used.
