Hertz DP1,500

The DP 1.500 from Hertz is a 1-channel amplifier designed to deliver impressive audio performance in vehicles. With its advanced Class-D technology, it achieves a stable output of 2 Ω in a compact design. Special features include an elegant status LED, a removable top plate and a solid milled terminal block. The universal compatibility and the balanced input circuit ensure interference-free signal transmission. Flexible controls such as adjustable input levels, low-pass and subsonic filters as well as an optional remote control allow individual adjustment of the sound. The amplifier offers a maximum output power of 590 W and is efficient in terms of energy consumption.
