About: Hertz DP 1.500 Mono Class-D Car Audio Amplifier

Despite its compact size, the DP 1.500 packs a punch with its maximum power output, featuring ADC (Advanced Class-D) 2Ω stable power output in a small and compact design. This innovative design allows for a potent audio performance without sacrificing space, making it an ideal choice for those seeking uncompromised sound in a limited footprint. Experience high-noise rejection with the balanced input circuitry of the Pre-in and Speaker-in, allowing for clean and interference-free signal transmission. The full set of controls, including adjustable input levels, low-pass crossover filters (50 ÷ 250 Hz @ 24 dB/Oct.), subsonic filter (25 Hz @ 24 dB/Oct.) and bass boost, provides users with the flexibility to fine-tune the audio to their preferences.
