Connect the mixer's main outputs to the line inputs on each powered speaker with balanced XLR cables. A powered speaker has its own amplifier, so it takes a line-level signal from the mixer and needs no separate amplifier. Start with the mixer main fader and each speaker's level control down, then raise them together.
Use balanced XLR cables from the mixer outputs
Plug a male-to-female XLR cable into the mixer's main output for the left channel and run it to the XLR input on the left powered speaker. Repeat the same connection for the right channel. A balanced XLR cable carries the mixer's signal to the speaker, and the shield in the cable keeps interference out along the run.
Match the mixer output to the speaker input
Check the mixer outputs and the speaker inputs before you plug anything in. Mixer main outputs are XLR or 1/4-inch jacks, and powered speakers take their signal through an XLR line input. Use an XLR cable where the mixer output and the speaker input are XLR, and a 1/4-inch cable only where the mixer output and the speaker input use that jack.
Set the levels down before you switch on
Turn the mixer main output level and the level control on the powered speaker down before you switch anything on. Switch the mixer on, then switch the speaker on. Raise the mixer main output, then bring the speaker level up until the sound is clear.
Choose a cable length that reaches the speaker
Measure the run from the mixer to the speaker and pick a cable that reaches without pulling tight. A cable that is too short strains the connectors, and a cable that is too long leaves slack to coil or trip over. Keep the cable off walkways and away from power cables where the run crosses them.
Check the connection when there is no sound
When a speaker stays silent, check the cable at the mixer output and at the speaker input and push the XLR plug in until it clicks. Check that the mixer channel is up and the main output is up, and that the speaker is switched on with its level control up. Swap the cable for a spare when the checks pass and the speaker still stays silent.

Frequently asked questions
Do powered speakers need an amplifier?
No. A powered speaker has its own amplifier built in, so it takes a line-level signal from the mixer through an XLR cable. Connect the mixer main output to the speaker line input and set the levels down before you switch anything on.
Can I use a 1/4-inch cable instead of XLR?
Yes, where the mixer output and the speaker input use 1/4-inch jacks. An XLR connection is the common choice because the cable is balanced and shielded.
Why do the speakers sound different in volume?
Check the level control on the speaker that sounds lower and the mixer output feeding it. A loose XLR plug or a cable that is not seated can drop the signal, so push the plug in until it clicks and check the mixer channel feeding that speaker.
How long should the XLR cable be?
Long enough to run from the mixer to the speaker without pulling tight, with slack to route around walkways. Measure the run and pick a length that reaches, since a cable that is too short strains the connectors.
