•A bridge/stereo switch for fast system setup

•A built-in 12 dB-per-octave electronic crossover, variable from 32 to 320 Hz

•Dynamic Bass Optimizer™ (DBO) 12 dB-per-octave subsonic filter with variable frequency (20 to 80 Hz) and Q for enhancing low frequencies while conserving amplifier power

•Individually selectable high- and low-pass filters (with through-pass) for amplifier and auxiliary outputs

•An amplifier input sensitivity control to match a wide range of input signal levels from 250 mV to 9 V

•Separate power supplies for each channel

•Five protection levels guard against over-voltage, under-voltage, over-power, over-temperature, and over-current situations

•2-color LED array indicates green when power is on and orange when protection is activated

•Industrial-grade, gold-plated, “pre-wire and plug-in” connectors for an easy-to-install high-quality interface

•Transparent control cover to deter tampering yet provide a clear view of installation settings
