• Check that all volume controls on the microphones, input channels CH 1 to CH 5, MASTER and BOOTH outputs are set to minimum.
• Connect the desired equipment to the input channels. Connect players to the LINE inputs of channels CH 1 to CH 5. And connect players with auxiliary line level output to the AUX inputs of channels CH 1 and CH 2 and set the input level selector switch to the AUX position. If you want to connect a turntable, use the PHONO inputs on channels CH 1 and CH 2 and set the input level selector to the PHONO position. If your turntable has a ground connection, connect it to the GND terminal on the rear panel.
• Connect a USB device or SD memory card with MP3 files to the corresponding port of the player.
• Connect the balanced or unbalanced MASTER output to a line-level input of an amplifier or power stage. If desired, you can connect the BOOTH output to self-amplified monitor speakers.
• Connect the devices to the power supply. Switch on the equipment in this order: peripheral equipment, followed by the mixer SM-1860U and lastly the amplifier or power amplifier (if necessary).
• Adjust the volume of inputs MIC 1 to MIC 3 and CH 1 to CH 5; and select the output buses to which to send each channel CH 1 to CH 5.
