Universal compatibility is a key feature of the DP 4.400, offering an operating supply voltage ranging from 6.5 to 16.5 V and speaker-in input sensitivity from 1.6 to 40 Vrms. The integrated Universal Speaker Simulator enhances versatility, ensuring optimal performance with a wide range of audio sources.
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, high/low-pass crossover filters (50-4000Hz 12dB/Oct.), and bass boost, provides users with the flexibility to fine-tune the audio to their preferences.
Convenience meets intelligence with the Automatic Remote Turn-On/Off feature, seamlessly triggered by OEM radio speaker outputs. This ensures hassle-free operation and an efficient power management system.
Whether utilizing Speaker-In or Pre-In level inputs, the DP 4.400 offers full-range pre-outs, providing further flexibility in system configuration. Elevate your car audio system with the Hertz DIECI POWER Amplifier DP 4.400 – where power, precision, and style converge for an unparalleled listening experience on the road.
Hi-Res Audio certification featuring a frequency response of 10 Hz – 45 kHz.
Dieci Power amplifiers are ultra-compact to ensure effortless installations in the increasingly narrow spaces of modern vehicles or the factory amp area.
Thanks to the built-in USS technology (Universal Speakers Simulator), DIECI POWER amplifiers can be correctly connected to head units with a “speaker load detection” function that monitors the presence of a low-impedance load to enable the audio outputs.
