The Presonus Quantum HD 8 ensures high-performance signal flow thanks to a custom low-latency driver and quality converters offering a dynamic range of 124 dB.

With its eight new MAX-HD microphone preamps, offering up to +75 dB of gain, it is suitable for a multitude of popular microphones even those usually requiring a preamp to boost gain (e.g. Shure SM7 B).

Its Re-Amp inputs and outputs, developed in collaboration with Fender, allow guitarists and bassists to sculpt their sound with amps and effects.

The Quantum HD 8 is Dolby Atmos compatible up to 5.1.4, providing an immersive audio experience.

Its Auto Gain knob automatically adjusts the gain level for perfect takes, while the Universal Control app allows flexible control of critical preamp functions, ensuring precise gain adjustment without interrupting the recording session.

Finally, it comes with professional recording software, including 12 months of Studio One+ subscriptions and a perpetual license for Studio One Professional Edition, it makes it easier to produce quality audio projects.
