| The BMPCC has a built-in stereo microphone and a 3.5mm stereo mini-plug input for external audio. The internal microphones are considered unusable for audio recording, unless it's simply as a reference sound for syncing an external sound source. | The BMPCC has a built-in stereo microphone and a 3.5mm stereo mini-plug input for external audio.

| On the other hand, the audio-input expects a +4dBm professional (but unbalanced) line level signal, while most consumer and semi-pro equipment are outputting -10dBm levels. For that reason, the audio levels often have to be raised to reflect that difference, when dealing with -10dBm sound, a rough estimate is setting the input level sensitivity to MIC and the input volume to 50%. | On the other hand, the audio-input expects a +4dBm professional (but unbalanced) line level signal, while most consumer and semi-pro equipment are outputting -10dBm levels.

| - | Since the most recent firmware still has no audio meters, it is difficult to check the volume on set. One way is connecting a field monitor or EVF that displays audio levels or recording through an external field mixer. | + | |
| + | ====Audio Meters? Yes, they are finally here.==== | ||
| + | |||
| + | With the 1.9.3 firmware update, the camera has gained simple audio meters. However, a better way to check audio may still be to connect a field monitor or EVF that displays audio levels or recording through an external field mixer. | ||
