4. For monitor audio from the camera during playback, connect the supplied AV cable to the MONITOR jack on the adapter. Attach the other end to the AV output of the camera.
5. Connect balanced XLR microphones, wireless mics or other audio sources to the LEFT and RIGHT XLR.
6. Set the GAIN switches.
   Set the Gain switches to HIGH for most microphones
   Set the Gain switches to LOW for very sensitive condenser microphones or recording very loud sounds
7. Set the PEAK switches for both channel to ON.
8. Set the MONITOR switch to PLAY to monitor the audio from the microphones during recording.

9. Set AGC ON / OFF.
   Please read the AGC Operation Guide for your reference.
10. Set the M/S switch.
    When using one channel, switch to M for mono.
    When using two channels, switch to S for stereo.
11. Set the LINE/MIC/PH switch.
    When using microphones and wireless systems, set to MIC for microphone.
    When using other audio devices, set to LINE for Line.
    When using microphones operating on phantom power, set to PH for phantom power.
    Note: Please DO NOT select Phantom level when recording with microphones that do not operate on phantom power, wireless receivers, mixing boards or any unbalanced device, because it may cause damage to both the adapter and audio device.

AGC Operation Guide

Automatic gain control (AGC) provide a controlled signal amplitude at its output, despite variation of the amplitude in the input signal. By disabling AGC function, the hiss can be eliminated when the camera is recording during quite moments.
When recording under stereo mode and set the AGC switch to off, a 20kHz sine wave will be sent from left channel to the camera to turn off the AGC function. The 20kHz sine wave can be easily filtered out, and the left channel can still be used for normal recording.
When recording under mono mode, you could set the M/S switch to S and recording only on the right channel. Leaving the left channel unused, so the 20kHz sine wave will not be recorded into the audio file.

Suggestion:

1. When turn the volume of each channel to the maximum but the recording sound is still low or not clear, you could turn off the AGC.
2. When turn the volume of each channel to the minimum but the recording sound is still high, you could turn off the AGC.
3. When the background noise affect the recording, please turn off the AGC.
4. If you don't want the 20KHz sine wave to be recorded into the audio file, please turn on the AGC.
   Please do a test recording and play back the audio to see if it is acceptable.
