High-Performance Active 500-Watt 12″ PA Subwoofer with Built-In Stereo Crossover
The B1200D-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 B1200DPRO 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.
