User manual ART 418

[. . . ] Each line input can be converted internally to a line output for that channel. Two 418's can be patched together via their Pre-Fade Out and Aux in jacks so that one is slaved to the other for up to 16 channels with one master level. Specifications · · · · · · · · · · · · · Input Impedance: 600 ohms Mic, 18K ohms Line, 10k ohms Aux. [. . . ] f) Re-adjust the MASTER LEVEL as required for best signal level. g) To inter-connect two 418s for 16 channels, run a shielded, unbalanced patch cable from the PRE-FADE OUT jack on mixer A to the AUX BUS IN jack on mixer B. Note that only the MASTER LEVEL on mixer B will now function. h) To convert the line input on a channel to a line output, unplug the 418's AC cord from the wall and remove the top plate. Move the jumper for the desired channel to pins 2 & 3. Now that channel's line input is converted to a line output and may be connected to the input of another mixer. Do not connect the output of a mixer or any other signal source here now or the unit may sustain damage. Be sure to replace the lid before plugging the unit back into the AC socket.
