2 Use a screwdriver or coin to turn each screw on the mixer from LOCK to OPEN until it clicks. 3 Securely hold the mixer’s handles to remove it from the speaker. Use only the mixer's handles when removing the mixer from the speaker and when carrying the mixer separate from the speaker. NOTE: The mixer can also be used when installed in the speaker. When you install the mixer into the speaker, make sure to match the indentations on the speaker cabinet to the corresponding parts on the mixer, and then turn each screw from OPEN to LOCK until it clicks. Turning the power on/off 1 Be sure that the mixer’s power switch is turned off. 2 Connect the included power cord to the [AC IN] jack, and plug the power cord into a power outlet. • To avoid any loud, unexpected noise from the speakers, first turn on the power to those connected devices that are closest to the sound source.

Outputting the signal to a main mixer • Connect a main mixer to the ST SUB OUT jack. The ST SUB OUT jack outputs the signal prior to routing through the MASTER LEVEL control. Adjust the level of output signal from the ST SUB OUT jack with the ST SUB OUT control. The ST SUB OUT control does not affect the MASTER LEVEL control. If only the L (left) ST SUB OUT jack is used, the mixer mixes the left and right signals and sends them to the jack.
