The following is described in the product page of the UR816C:
“HA mode is a special mode that allows one of a pair of UR816Cs to be used as an eight-channel mic preamp and ONE SET OF MONITORS conveniently used with both units”.
The description of HA Mode in the User Manual says:
“It can be used as an extension of monitor output.”
Does this mean that using two units would give me up to 20 analog outs (2x10) being controlled by a single monitor section (Output Level, Dim and Mute)?
