a line input such as a CD player or tape recorder output. Be sure that the volume of the input source is the same as it would be during normal use. If it isn�t, you might have to readjust these levels during the middle of the set.

Remember to push in the EQ IN/OUT button or the EQ controls won�t do anything. Disengage that channel�s SOLO switch. Repeat for each channel.

To get sound out of the speakers, turn up channel 1 and 2 faders to the �U� mark and slowly turn up the MAIN MIX fader to a comfortable listening level. Sing and play. You�re a star! Adjust the faders for channels 1 and 2 to bring your voice and your instrument up and down to create your own mix.

Connections
If you already know how you want to connect the Onyx 1620, go ahead and connect the inputs and outputs the way you want them. If you just want to get sound through the mixer, follow these steps: 1. 2. Plug a microphone or other signal source into channel 1�s MIC or LINE input. Plug in the detachable linecord, connect it to an AC outlet, and turn on the Onyx 1620�s POWER switch. Connect cords from the Onyx 1620�s MAIN OUTS (XLR connectors on the rear panel and 1/4" TRS connectors on the front panel) to your ampli�er. 4. Hook up speakers to the amp and turn it on. If the ampli�er has level controls, set them however the manufacturer recommends (usually all the way up).

Other Nuggets of Wisdom
� For optimum sonic performance, the channel and MAIN MIX faders should be set near the �U� (unity gain) markings. Always turn the MAIN MIX fader and CONTROL ROOM knob down before making connections to and from your Onyx 1620. When you shut down your equipment, turn off the ampli�ers �rst. When powering up, turn on the ampli�ers last. Never listen to loud music for prolonged periods.
