CONNECTIONS

The XLR connectors use the following AES standard:

PIN 1 = GROUND (SHIELD)

PIN 2 = HOT (+)

PIN 3 = COLD (-)

At this point you can connect the power supply cable and the signal cable, but before

turning on the speaker make sure that the volume control is at the minimum level (even

on the mixer output). It is important that the mixer is already ON before turning on the

speaker. This will avoid damage to the speakers and noisy “bumps” due to turning on parts

on the audio chain. It is a good practice to always turn on speakers at last and turn them

off immediately after the show.

Now you can turn ON the speaker and adjust the volume control to a proper level.
