The unit is powered by a 2500 watt digital amplifier module which is loaded in a separate chamber in the rear of the box, mechanically insulated from vibrations. Capable of producing 136 dB max SPL, the SUB 8004-AS can perform in the most demanding situations. The input board includes volume control, signal, power and limiter LEDs, deep/punch switch, high pass, phase, and cardioids switches and delay control. Weighing in at 51 pounds and a relatively compact 23” x 22” x 28”, the Baltic birch tour grade cabinet can be stacked with the NX L23-A and NX L24-A active line array modules and offers multiple configuration options with the HDL 10-A and HDL 20-A active line array modules.
