dB1500a and dB1800a STEREO SUB WITH POWERED SATELLITES

Operating the dB1500a and dB1800a

Two dB1500a or dB1800a’s can be used with any pair of powered full range enclosures like the Samson dB500a, XP200

and XP300. Below is a typical system set-up using two dB1500a and dB1800a’s with a mixer and a pair of powered sat-

ellite loudspeakers. The dB1500a and dB1800a’s inputs and outputs utilize industry standard XLR connectors. For a

detailed wiring diagram, see the section "dB1500a and dB1800a Connections" on page 11. Follow the steps below the

diagram to set up your system.

• Connect the mixer’s left output to the left-side dB1500a

and dB1800a’s left input and the mixer’s right output to

the right-side dB1500a and dB1800a’s right input. Now

connect the left-side dB1500a and dB1800a’s left output

to the input of the left powered satellite, and right-side

dB1500a and dB1800a’s right output to the input of the

right satellite. Switch both the Stereo/Mono selector

switches to the Stereo position.

• Now adjust the crossover SWEEP to the desired frequen-

cy. For the db500a select 60-80Hz and for the Expedition

XP200 & XP300 select 80-100Hz. If you are using another

brand of powered speaker as satellites with the dB1500a

and dB1800a, consult their respective owners manuals

for the recommended crossover point.

• Lower your mixer’s master outputs to all the way off.

Now set the level of your powered satellites up to the

normal operating level. Run an audio signal (like some

music from a CD) through your mixer and raise the level

to a comfortable listening volume. Now slowly raise the

dB1500a and dB1800a Level control and listen to the

low frequency output. Adjust the dB1500a and dB1800a

to the level to low frequency output that you like. Now

when you raise and lower your mixer’s output, the

dB1500a and dB1800a and satellites will track at the same

relative volume.
