to mono and check for unevenness in the frequency range caused by phase cancellation and
reinforcement of particular frequencies. If the sound changes significantly or sounds "hollow" when
summed to mono, this may indicate phase issues caused by a less than optimal mic placement.
When mixing, it's also a good idea to check mono compatibility. Beyond questions of phase, any
masking caused by overlapping frequencies is most easily heard when listening in mono. Try starting a
mix with Sum to Mono engaged - once you have something that sounds good, then disengage Sum to
Mono and revel at the beautiful stereo mix you've created!
Quartet's top panel Touchpads may be set to engage Sum to Mono on the Speaker outputs, the
headphone outputs or both at the same time. See Device Settings Tab Window.
