Ask in plain language — there are no commands to memorize. Everything works by typing or by voice, and the examples are just examples; say it your way.
In PEP FOH these change the house mix; in PEP IEM the same kinds of requests change your monitor mix only. See PEP FOH vs PEP IEM.
"What's channel 1 at right now?"
"What's the kick sitting at?"
"What channels are on this board?"
"How much kick is in the drum mix?" (a send level)
A little / a lot — let PEP judge the amount:
"Bring the vocals up a touch." · "A bit more kick." · "Back the guitar off a little."
An exact amount:
"Vocals up 2." · "Drop the snare 3 dB."
Set it to a specific level:
"Set channel 1 to minus six." · "Put the kick at unity."
A few at once:
"Bring all the drums up a touch." · "Vocals and keys up a little."
"Fade the music out over four seconds." · "Slowly bring the pad down." · "Fade channel 8 to silence."
Need it instant? "Snap the kick to minus ten."
"Mute channel 5." · "Unmute the vocal." · "Kill the talkback mic."
PEP adjusts how much of a channel feeds an effect (reverb, delay, etc.):
"More reverb on the lead vocal." · "Less verb on the acoustic." · "Put a little reverb on the snare."
Feeds to wedges and in-ears (in PEP IEM, pick your mix first):
"More me." · "More kick in my ears." · "Less guitar in my mix."
From FOH: "Turn up the wedge for the MC." · "Give the drummer more click."
"John's on channel 1." · "Call channel 3 'acoustic'." · "Rename 5 to drums."
Names show up in LV1, MyFOH, and PEP at once — then you can just say "bring John up."
"Undo." · "Put it back." · "Actually, undo that."
Keep going naturally. After a change, "a little more" or "actually, back down" works — PEP remembers what you just touched.
Voice safety net. In voice mode, PEP asks you to say "confirm" before silencing the main PA.
It acts immediately — there's no "are you sure" on every move, so lean on "undo."
