Samson D1800 User Manual

To create a stereo full range audio system, two D1800s can be used with any pair of 

powered full range enclosures (like the Samson Auro D412 and D415). Below is a typi-

cal system set-up using two D1800s with a mixer and a pair of powered satellite loud-

speakers. The D1800’s inputs and outputs utilize industry standard XLR connectors. 

For a detailed wiring diagram, please see the section "Connections" on page 10. Follow 

the steps below to set up your system.

•   Lower your mixer’s master outputs all the way off. 
•  Connect the mixer’s left output to the left-side D1800's left input, and the mixer’s 

right output to the right-side D1800's right input.

•  Now connect the left-side D1800’s left High Pass output to the line input of the left 

powered satellite, and right-side D1800’s right output to the line input of the right 

satellite.

•  Now, set the level of your powered satellites up to normal operating level. Run 

an audio signal (like music from a CD) through your mixer, and raise the level to a 

comfortable listening volume. 

•  Next, slowly raise the D1800s' Level controls and listen to the low frequency out-

put. Adjust the two D1800s to the desired level of low frequency output. 

•  Now when you raise and lower your mixer’s output, the D1800s and satellites will 

track at the same relative volume.
