INTEGRATED CLASS-D AMPLIFICATION & DIGITAL SIGNAL PROCESSING: Built-in Class-D amplifier delivers 800W RMS / 1600W peak power. Onboard DSP features include four EQ presets, dynamic bass enhancement, RMS dynamic processing, a 2nd-order IIR filter, phase switch, and a switchable low-pass filter adjustable from 40 Hz to 180 Hz.

TOUR-READY BIRCH PLYWOOD ENCLOSURE. All-birch plywood cabinet minimizes resonance and vibration, reinforced with aluminum extrusion rigging hardware and a heavy-duty perforated metal grill for touring and installation use. Finished in a white textured coating, it is well suited for environments such as houses of worship, clubs, schools, and modern installation spaces.

FLEXIBLE SYSTEM DEPLOYMENT. Supports both flown and ground-stacked configurations. Flown systems use the ZETHUS-210FF flying frame (sold separately). For ground-stacked setups, the ZETHUS-118SWPW serves as the base for ZETHUS-210WPW full-range line array loudspeakers, with optional ZSCB-118S caster board (both sold separately) for secure positioning and simplified transport.
