Canon 814XL-S - Manual (Page 134)

AUXILIARY INPUT AND MIXING
To record sound from audio equipment such as a
tape recorder, television, or radio while filming,
use the AUX input jack instead of a microphone
which might pick up unwanted noises from the
surrounding area.
1. Set all recording dials at their normal positions
when recording directly from audio equip­
ment.
2. Connect the camera to the sound source with
the Connecting Cord C300L optional acces­
sory.
3. After turning on the sound source, monitor
the sound through the camera by pushing the
shutter release button half-way. Adjust the
volume of the sound source as appropriate,
and monitor the sound quality in the earphone
and volume level meter once again.
4. If you wish to record conversation or natural
sounds along with the audio input, use the
microphone in its MIC jack along with the
auxiliary source connected to the AUX jack to
mix the sounds.
