What is special about the automatic power-on feature of the D5.350?

The automatic activation of the DD Audio D5.350 allows for convenient operation without manual intervention. As soon as an audio signal is present, the amplifier activates automatically, making it easier to use. This feature is particularly practical in vehicles, where the on and off process can be automated to synchronize the amplifier with the main sound system. Additionally, the amplifier has LED clipping indicators that provide visual feedback on potential overdriving. This visual control also increases operational safety and ensures that the amplifier works optimally.

What efficiency features does the DD Audio D5.350 have?

The DD Audio D5.350 demonstrates efficiency with its damping factor of over 100 and a THD value of less than 0.2%. These planned values enable precise and distortion-free sound reproduction. The amplifier operates in the frequency range of 30 Hz to 25 kHz, providing a comprehensive bandwidth for audio playback. The use of an anodized aluminum heat sink effectively minimizes heat generation and the associated power loss. With a maximum current draw of 90 Amperes, it also ensures efficient power usage, resulting in long-lasting performance and consistent sound quality.

Can different speaker wire gauges be combined with the D5.350?

The DD Audio D5.350 is compatible with various speaker wire gauges and can be operated with a speaker wire thickness of 4 mm².
