SRM1850 • SRM2850 Powered Subwoofers

BIG PA

Hookup Diagrams continued...

Feel the awesome power! In this example, a pair of SRM2850 subwoofers line each side of the venue...

four subs total! The top sub on each side is connected to an SRM750 loudspeaker. This fully powered PA 

is desired when you really need a slammin’ system with deep, commanding lows and nice, crisp highs.

Here, the L/R outputs of a DL1608 mixer are connected directly to the channel A input of each  

bottom SRM2850 subwoofer. The channel A full range output of each (bottom) SRM2850 subwoofer  

is connected directly to the channel 1 input of each (top) SRM2850 subwoofer. 

From here, the channel A high pass output of each (top) SRM2850 subwoofer is connected directly to the 

channel 1 input of each SRM750 loudspeaker. Be sure that the gain knob on each is set to “line” or get 

ready to be blasted! Select the SRM750 high pass mode on the SRM2850 for a matched system.

***Please note that the SRM750 loudspeakers are stacked on top of the SRM2850 subwoofers, not 

pole-mounted. SRM750s may be pole-mounted on a tripod stand, but must be stacked on subwoofers.
