RDL18. new RDL.level adjustment gear

also brand new:
a stackable, and fully programmable level adjustment tool (PGA2310 based , 0.5db steps)

can be used as 2channel , 4 channel or 4channel + inversed monitor RDL unit.

at the moment i use a 24 step elma to control 24 steps. nice haptic experience.
but any other step configuration can be quickly implemented
also fader knobs. or mute switches.
from -95.5 to +31.5 db all is possible
input/output with that 1206, 1646 chips.
