[. . . ] â· Don't place metal objects or spill liquid inside the unit. No objects filled with liquids, such as vases, shall be placed on this appliance. If a foreign object enters the unit, immediately disconnect the mains power. [. . . ] â· To avoid condensation to be formed inside, allow the unit to adapt to the surrounding temperatures when bringing it into a warm room after transport. Condense sometimes prevents the unit from working at full performance. CLEANING THE MIXER: Clean by wiping with a polished cloth slightly dipped with water. Do not use volatile liquids such as benzene or thinner which will damage the unit. Except for microphones, headphone and zone outputs, all connections are cinch. (example: JB Systems code: 2-0370) For more information on connections, please refer to the next chapter. Be sure to turn off the mixer before you make changes to the different connections. DJ MICRO input: The DJ micro can be connected to the XLR/Jack input on the front plate or to the stereo jack on rear panel. This input is balanced but accepts any kind of microphone equipped with an XLR or jack connector. TALKOVER level: When you switch the talkover(3) on, you can adjust the amount of muting on input channels 2 to 5. The more you turn to the right, the more these channels are muted while talking through the DJ Micro(1). TALKOVER switch: Use this switch to automatically mute the input channels 2 to 5 while you are talking through the DJ microphone. Use the zone selectors(4) to choose on which output the talkover should work. Attention: the talkover will only work on the zone you selected for the DJ Micro. ZONE switch: for every input channel you can choose to which zone (master) it should be routed. This means that you can use this mixer to serve two different rooms with completely different music! [. . . ] LINE input: Used to connect any line level sound source to this channel. RECORD BUS A: line level output with the signals from channels 2 to 5. Important note: the tone controls, DJ microphone and talkover function are NOT available on this output. [. . . ]
