Usage

1. Verify proper voltage selection on the IEC style power connector for your location. Connect the AC cord to a grounded AC outlet.
2. Connect low-impedance mics to the XLR sockets.
3. Connect shielded unbalanced line inputs to the 1/4 inch jacks.
4. For mic channels requiring phantom power (for condenser mics), set the appropriate PHANTOM POWER DIP switches in the down position. Do not engage phantom power on a channel unless it is for a condenser microphone.
5. Switch on the power and set the MASTER LEVEL to the 12 way setting, then adjust the channel LEVEL controls as required for the best mix and level. Adjust the channel TONE controls for the desired balance of lows and highs. Center setting is approx. neutral.
6. Re-adjust the MASTER LEVEL as required for best signal level.
7. 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.
8. 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. Inside you will see a row of jumpers. 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.
