Operating the dB1500a and dB1800a
The dB1500a or dB1800a is a perfect addition to any pair of powered full range enclosures like the Samson dB500a,
XP200 and XP300. Below is a typical system set-up using the dB1500a and dB1800a with a mixer and a pair of powered
satellite loudspeakers. The dB1500a and dB1800a’s input 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.
dB1500a and dB1800a MONO SUB WITH POWERED SATELLITES
• Connect the mixer’s left output to the dB1500a and
dB1800a’s left input and the mixer’s right output to the
dB1500a and dB1800a’s right input. Now connect the
dB1500a and dB1800a’s left output to the input of the left
side powered satellite, and the dB1500a and dB1800a’s
right output to the input of the right side satellite. Switch
the Stereo/Mono selector switch to the MONO position.
• Now adjust the crossover SWEEP to the desired frequency.
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. Next, slowly raise the
dB1500a or dB1800a Level control and listen to the low
frequency output. Adjust the dB1500a or dB1800a to the
level of low frequency output that you like. Now, when
you raise and lower your mixer’s output, the dB1500a or
dB1800a and satellites will track at the same relative vol-
ume.
