Plug in, but do not turn on, the DJ mixer and both amplifiers. Turn the volume knob on both amplifiers to zero.
Connect one end of an XLR cable to left output of the DJ mixer and the other end into Input one of the audio snake. Connect the right output of the DJ mixer to Input two of the audio snake with another XLR cable. The audio snake is labeled clearly.
Connect one XLR cable from Output one of the snake to the left input of the first amplifier. The amplifier is clearly marked. Connect another XLR cable from Output one to the left channel of the second amplifier. Repeat this for Output two and the right channels of the amplifiers.
Connect the left and right outputs of amplifier one to a pair of speakers with two XLR cables. Do the same with amplifier two and another pair of speakers.
Power on the DJ mixer, then power on the amplifiers in this order to avoid possible damage to the speakers from the electrical signal created by powering on the DJ mixer. Increase the volume on the amplifiers to the desired level once the DJ mixer is turned on.
