Configuring Your Speaker System

Before you start plugging in cables, you should take a minute to decide how you want to interface your new subwoofer. There are several ways you can interface the dB1500a and dB1800a, however most systems set-ups fall into two categories, Stereo or Mono (Common) sub operation.

Common Sub Operation

In most cases a common sub, or mono bass operation is desired. This is true for several reasons, but mostly because low frequencies produced by a subwoofer tend to be non-directional. Since low frequency waves take so much space to actually develop, you can't tell if the sub bass is coming from the left or right side, unless of course you're in a very large room. Because of this phenomena, just about all sub bass material is mixed in mono.

Stereo Sub Operation

In larger rooms, as well as in theatres and theme park installations (for low frequency special audio effects), two dB1500a and dB1800a's can be used in stereo.

Operating the dB1500a and dB1800a

dB1500a and dB1800a CONTROL PANEL

The dB1500a and dB1800a's control panels provide the connections and user interface to the dB1500a and dB1800a's internal electronic crossover and power amplifier section. The internal amplifier is a 1000 Watt amplifier capable of producing incredible bass output while running super cool. The dB1500a and dB1800a employ an electronic crossover that adjusts the high frequency cutoff point for the subwoofer, and also, a high passed output for your satellite speakers. You will achieve a tremendous benefit in sound quality by running your satellite speakers from the dB1500a and dB1800a's High-Pass outputs. The reason for this is that when your satellite speaker receives the filtered output from the dB1500a and dB1800a, it will no longer be looking at the frequencies below the crossover point. Let's say your satellite speaker has a natural frequency roll-off at 70 Hz, and you are sending full range signal (as low as 20Hz) to the satellite amplifier and speaker. Even though the speaker can only reproduce 70Hz and up, the amplifier is still outputting 20-70Hz, which is wasted power and essentially turns into heat. By using the dB1500a and dB1800a's High-Pass output, the satellite amplifier and speaker never see the frequencies lower than what's set by the Sweep frequency. This means you'll have more power dedicated to the frequencies you want the satellites to deliver, resulting in a much cleaner sound with more headroom.

Level Control

The level control is used to adjust the amount of volume from the dB1500a or dB1800a subwoofer. In addition, the Level control will also control the output volume of the high-passed outputs. Therefore, if you are using the dB1500a or dB1800a without using the high-passed outputs (for example, when the dB1500a or dB1800a are connected to an external crossover) the Level control adjusts the low frequency output of the dB1500a or dB1800a. If you are using the dB1500a or dB1800a's internal electronic crossover to run satellite speakers, then the Level control will adjust the overall system volume.

SAMSON dB1500a Hz 105 0 10 LEVEL 30 200 PEAK ◀ STEREO MONO ►

Sweep

The Sweep control selects the upper range cutoff frequency of the dB1500a and dB1800a's internal electronic crossover. The dB1500a and dB1800a's crossover provides a 12dB per octave Linkwisz-Riley filter curve. The Sweep limits the high frequency that the dB1500a and dB1800a will reproduce, and at the same time, the high-passed output tracks the selected crossover frequency as the lower limit frequency.

Stereo / Mono Switch

The Stereo/ Mono switch selects either stereo or mono bass operation. When set to MONO, the dB1500a and dB1800a will combine, or sum, the left and right signals and send a mono signal to the amplifier of the dB1500a and dB1800a. In this mode, the original stereo signal is passed through the left and right outputs only now the stereo signal is filtered at the frequency set by the Sweep control. In Stereo mode, the low frequency signal is not summed, and you can choose either the left or right input accordingly for each side of the system.

The In and The Outs

The dB1500a and dB1800a features electronically balanced inputs and outputs so that any possible HUM problems are greatly reduced when interfacing to other equipment. XLR connectors with industry standard pin-outs are used for easy interface from mixer and other professional audio gear. A detailed wiring diagram can be found in the section "dB1500a and dB1800a Connections" on page 11 of this manual.

dB1500a and dB1800a MONO SUB WITH POWERED SATELLITES

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.

XP200 XP200 EXPEDITION PL1602 Mixer dB1500a STEREO MONO

• 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 volume.
