Headphone/Aux Output

The codec has a 6.35mm (1/4") RTS stereo HEADPHONE output for monitoring inputs and return audio. If you are using analog inputs or digital inputs you will see audio metering on the PPMs and can monitor it with the headphones.

Important Note: The front panel HEADPHONE output and rear panel HP/AUX output share the same hardware output. This means both are switched and configured together. I.e. both outputs are either a stereo headphone output (default setting), or a balanced mono auxiliary output.

 

Configure for Headphone and Aux Output

Both the front panel HEADPHONE and rear panel HP/AUX outputs are configured as stereo headphone outputs by default. To adjust this setting:

 

1.Press the SETTINGS Settings button button.

2.Navigate to Audio and press Ok button.

3.Select HP/Aux Out and press Ok button to toggle between Headphone and Aux Out.

3.Press the down down arrow button navigation button to select the Send/Return audio balance and use the left left arrow button or right right arrow button navigation buttons to adjust the balance. The Send/Return audio balance dictates whether the front panel HEADPHONE output and the rear panel HP/AUX output monitors send (input/encoder) audio only, return audio only (decoder audio from a connected device), or a mix of both send and return audio.

4.Press RETURN Back button when you have finished to exit the menu.

 

Note: Headphone levels can also be adjusted by pressing the SETTINGS Settings button button, navigate to Audio and then HP Vol/Bal and press Ok button.

 

Adjusting the Monitor Source
