Description
Hertz DP 4.400 4-channel class AB amplifier
The Hertz DIECI POWER DP 4.400 is a new 4-channel class AB amplifier that takes car audio to a new level. Thanks to its Hi-Res certification, this amplifier offers a frequency response of 10 Hz to 50 kHz, ensuring that every nuance of your music is reproduced accurately and crystal clear.
Despite its compact size, the DP 4.400 is powerful and can be bridged to 2 or 3 channels. It is also capable of 2 Ohm connection. The innovative design of the device allows for powerful sound reproduction without sacrificing space, making it an ideal choice for those looking for uncompromising sound in a small space.
The aesthetics of the amplifier are as impressive as its performance. Stylish LED lighting, a solid machined body, and a removable top panel that protects the controls and connections create a sleek and sophisticated design. This unit is easy to fit into any interior.
Universality is a key feature of the DP 4.400, with an operating voltage range of 6.5-16.5 V and a speaker input sensitivity of 1.6-40 Vrms. The integrated speaker load simulator increases versatility and ensures optimal performance with a wide range of audio sources. The device's Hi-Input connections can therefore be connected to cars that monitor the speaker load.
The device features high-quality protected and balanced Pre-in and Hi-in signal inputs, enabling clean and interference-free signal transmission. Full control options, including adjustable input levels, high- and low-pass crossovers (50 - 4000 Hz 12dB/Oct.) and bass boost, give users the flexibility to fine-tune the sound to their preferences.
Automatic wake-up makes installation easy.
Whether using the Speaker-In or Pre-In level inputs, the DP 4.400 offers a full-band Pre-out output. This means you can connect a separate bass amplifier to it without separate branching.
Take your car's audio to the next level with the Hertz DIECI POWER amplifier DP 4.400 - where power, precision and style combine to ensure an unparalleled listening experience on the road.
