11 connecting audio inputs the audio inputs are located on the rear panel. The cm16a uses terminal block connectors for the audio inputs. They are sometimes called “phoe- nix” or “euro”connectors. These connectors allow the installer to pre- wire the input terminations before the cm16a is installed ...

15 there are three operating modes for recalling presets using the rly/trg in of the cm16a and a set of external contacts (switch, relay or other such device). These modes are set up and accessed using the qscontrol software or rs232/telnet sessions. The purpose of this portion of the manual is to o...
