The DS18 FRP-3.5K is a 1-channel, full-range Class D monoblock car amplifier in a Titanium finish. It produces up to 3500 watts RMS at 1 ohm, with 4000 watts max burst power. Its frequency response runs from 10Hz to 20KHz, so it can drive subwoofers, mids, horns, compression drivers or active systems.
It uses a high-efficiency micro digital design in a compact chassis. Construction includes a four-layer PCB, surface mount components, Tiffany-style RCA inputs and metal click-step control knobs. Two cooling fans and thermal, overload, short circuit and voltage protection are built in.
Variable crossovers and a bass boost allow tuning. LED indicators show power, protect and clip status.
