Essential Information About the Quantum HD 8 26x30 USB-C Audio Interface
- 8 MAX-HD Preamps (75 dB) with Automatic Gain for clean, powerful, and perfectly consistent microphone recordings.
- 32-bit/192 kHz Conversion, ultra-low latency direct monitoring, and built-in loopback for recording and streaming.
- Comprehensive Studio Connectivity: 8 XLR/jack combo inputs, 2 instrument inputs, ADAT x2, S/PDIF, MIDI, 2 Re-Amp outputs.
- High-resolution Color Display and software control (Studio One / Universal Control) for gain, routing, and phantom power management.
A New Era in the Quantum HD Range
Designed to succeed previous generations, the Quantum HD 8 features new MAX-HD preamps with wide gain headroom, more peak-tolerant 32-bit conversion, and a
color display for immediate visual feedback. Its built-in
speaker switching simplifies A/B comparisons, while the
Re-Amp outputs speed up guitar workflows. The result: greater transparency, ergonomics, and faster daily operation.
Built for Multitrack Recording, Creation, and Streaming
From solo artists to production studios, the Quantum HD 8 effortlessly handles multi-mic drum kits, full bands, voice-overs, or video podcasts. The two front-panel Hi-Z inputs facilitate guitar/bass recording, the
loopback streamlines live broadcasts and tutorials, and the two stereo headphone outputs provide independent monitoring for engineer and artist.
Key Features for a Pro Workflow
Preamplification and Conversion
The 8 MAX-HD preamps deliver up to 75 dB of gain with 48 V phantom power and
automatic gain to prevent unexpected clipping. The
32-bit/192 kHz conversion offers a wide dynamic range and ideal headroom for demanding editing and mixing.
Monitoring and Routing
With ultra-low latency direct monitoring, a high-resolution color display, and
speaker switching, you make decisions faster. The
Re-Amp outputs let you send your tracks to amps/effects for authentic re-amping without extra gear.
Connectivity and Expansion
Featuring 8 combo inputs, 2 instrument inputs, 2 pairs of ADAT, stereo S/PDIF, MIDI, 2 balanced TRS main outputs, and 8 line outputs, you get
26 inputs / 30 outputs ready for complex setups and expansion via external converters.
Software Control and Integration
From Studio One or the Universal Control app, manage preamps, phantom power, routing, and save your scenes. The integrated monitoring mixer and
loopback streamline the entire workflow, while the Studio One+ subscription and perpetual Studio One Professional license let you start producing immediately.
