Sorry, I meant "AFR".

"ATV" means "Adjustable Travel Volume"The amount of travel the CHANNEL will move. Also known as the "End Point". The 14mz has it listed as "ATV (end point)". "Travel" is how much the channel moves when you move a control from end-to-end. "Limit" is the total amount of travel a channel will move when it's influenced by a mixer.

"AFR" means "Adjustable Function Response". This adjusts the FUNCTION. You can have several channels under a single function.

When we mentioned that you can use several instances of "throttle", we meant that you would set up, for instance, channel 1 as "throttle", channel 2 as "throttle", and channel 3 as "throttle". You can then go into each channel and adjust their AFR curves.

If you set channel 1 as "throttle", channel 2 as "throttle2", and channel 3 as "throttle3", then you can adjust only the throttle AFR, because the system assumes only one function with three channels working under it.
