# Duet's Assignable Touchpads

Duet's two assignable touchpads can be assigned to control many of Duet's settings and parameters. Use them to setup advanced muting functions when recording yourself or to toggle between program and cue during a DJ set. Assigning functions to the touchpads is done on the Device Settings tab of Maestro.

## Mute outputs

To mute the speaker and headphone outputs, assign one of the user assignable touchpads in Maestro 2 to the desired mute function.

## Dim outputs

The Dim function lowers the output volume by 15 dB. This function is convenient when you want to briefly lower the playback volume in the speakers or headphones in order to hold a conversation without completely muting the output.

## Sum to Mono

The Sum to Mono function is used to examine phase relationships on stereo tracks. When it is engaged, phase errors become more noticeable. See Sum to Mono (as link) for more information.

## Toggle Headphone source

Toggle Headphone source is used to switch the Headphone output between Out 1-2, Out 3-4 and Mixer. This function is especially useful for digital DJs to switch the headphone output between the House output (sent to Out 1-2) and a cue output (sent to Out 3-4).

## Clear Meters

The Clear Meters function will remove held peak and over indicators on software and OLED meters when Peak Hold or Over Hold (in the System Setup tab window) is set to Infinite.
