Question on Mixer

Hi every one,
a question on the MIXER for experts :

for a value of : actuator output [-1, +1]
Does it generate a linear PWM value from 900 to 2100 or from PWM_MIN to PWM_MAX ?

My mixer for this Chanel look like this :
M: 1
O: 10000 10000 0 -10000 10000
S: 0 0 0 20000 -10000 -10000 10000

From PWM_MIN to PWM_MAX afaik.

Thank you for your reply !
