*Note: The Audio MIDI Setup utility window within Mac OS® X versions 10.6 and later 
has a slightly different layout, but offers the same options and functionality as described 
here.

A

System Settings:

•  The 

Default Input

 and 

Default Output

 options allow you to choose the audio 

interface you want your Mac® audio applications to use by default. If you want this 

to be your Line 6 device, select it here. 

•  The 

System Output

 option allows you to choose which audio interface the Mac

®

System sounds are played through. 

B

Device Properties:

 Choose your POD HD Pro device here to allow the Audio Input 

and Audio Output options display its settings.

C

Audio Input & Output Options:  

If you’ve selected your POD HD Pro in the Device 

Properties, these settings will all refer to your POD HD Pro device:

•  You’ll see the Input and Output selectors both disabled, showing 

Master Stream

 for 

each. POD HD Pro includes one stereo “fixed” Input (Record Send 1-2) and one 

fixed stereo Output (Out 1-2).

•  The 

Source

 options are also disabled for POD HD Pro. 

•  The Format selectors show you the Sample Rate* and Bit Depth that POD HD Pro 

is operating at for recording. The Bit Depth for POD HD Pro is fixed at 24 bit. 

*It is recommended that you do not use the Sample Rate selectors in this window to set the 
sample rate when your audio software is running. Typically, your audio software will offer a 
sample rate option within its own “Preferences” settings.  

•  The 

Input Volume Sliders 

offer level control for the Record Send signal fed to your 

recording software.  Note  that  the  sliders  offer  12dB  of  input  gain  at  the  highest 

setting.

•  The 

Output Volume Sliders 

offer stereo level control for your software’s audio 

playback fed to POD HD Pro.
