Mute Outputs
You can assign one of the Touchpads to mute the Speaker, Headphone, or All Outputs.
Dim Outputs
The Dim function lowers the output volume by 15 dB. This function is convenient when you want to briefly lower the playback vol-
ume without completely muting the output.
Sum to Mono
The Sum to Mono function is used to examine phase relationships on stereo tracks. When engaged, the left and right output signals
are combined and phase errors between the two become exponentially more noticeable.
