Product Information Document Portable Speakers &630-*7& #%130 High-Performance Active 1400-Watt 18" PA Subwoofer With Built-In Stereo Crossover Take Control The B1800D-PRO features balanced XLR inputs and outputs, as well as balanced XLR Thru jacks for connecting additional enclosures. A Boost Frequency knob targets a boost frequency between 45 Hz and 90 Hz. Flick the Boost switch to give your selected frequency a +10 dB boost. The B1800D-PRO also has a High Cut dial that provides precision control over the upper-corner frequency of the subwoofer's amplifier. The High Cut dial does not affect the Thru signals, only signals directed to the subwoofer (however, it does affect the Output socket signals sent out to full-range speakers). A Level knob controls the input gain, and the Phase switch reverses output phase to compensate for frequency cancellation between the subwoofer and satellite speakers. LEDs show operational status at a glance, including power, signal present and input overloads. Which Speaker Do I Need? As you have probably noticed, we make these subwoofers in two different woofer sizes. Which one is right for you? An 18" woofer has more surface area with which to move air than a 15". If you're running sound for a jazz combo in a dinner club, a single B1500D-PRO might be all you'll need. But if you need to serve up pulse-pounding techno at a large, standing-room-only dance club, you might need a pair of B1800D-PROs to really ignite the dance floor. 3 of 7
