On the specs for the sound, you mentioned:

"<span style="font-family: Verdana, Arial; font-size: 13px; background-color: rgb(251, 252, 255);">- 2 channels sound with 3W/4 Ohm on-board</span>amplifier<span style="font-family: Verdana, Arial; font-size: 13px; background-color: rgb(251, 252, 255);">(replaceable with optional 8W/4 Ohm one)</span><br style="font-family: Verdana, Arial; font-size: 13px; background-color: rgb(251, 252, 255);" /><span style="font-family: Verdana, Arial; font-size: 13px; background-color: rgb(251, 252, 255);">1 Channel dedicated to engine sounds</span><br style="font-family: Verdana, Arial; font-size: 13px; background-color: rgb(251, 252, 255);" /><span style="font-family: Verdana, Arial; font-size: 13px; background-color: rgb(251, 252, 255);">1 Channel dedicated to all other effects, with priority table to play them"

Are those 2 channels pre-mixed inside 1 chip, or will it be possible to tap into the " engine sounds " channel to power an "Acoustic Smoker" for exemple???<br type="_moz" /></span>
