Focusrite SCARLETT2i2-4G

Studio-Grade Conversion in a Compact USB-C Interface

The Focusrite SCARLETT2i2-4G is a 2-in/2-out USB-C audio interface offering studio-quality conversion. Designed with two XLR/TS inputs, balanced line outputs, and a custom headphone amplifier, the unit fits into a 595 g chassis.

Auto Gain, Clip Safe, and Air Mode

Fourth-generation enhancements include a session-protection suite. By pressing a single button, Auto Gain determines the optimal level, while Clip Safe scans the input up to 96,000 times per second, automatically reducing gain to avoid overload. With Air Mode, you can add Presence and Harmonic Drive coloration to your signal.

Two Ultra-Low-Noise Preamps with 69 dB of Clean Gain

Delivering 69 dB of usable gain with an EIN of -127 dBu, the preamps also offer switchable 48V phantom power for condenser microphones.

• Number of Preamps: 2 — record a vocal microphone and an instrument at the same time
• With a Mic Gain Range of 69 dB, even demanding dynamic and ribbon microphones can be used without added noise.
• Inputs: 2x XLR mic, 2x 6.3 mm TS line/Hi-Z

24-bit / 192 kHz Conversion with 120 dB Dynamic Range

Converters used here are derived from the RedNet professional line, delivering 120 dB of dynamic range on the A/D stage.

• Sample Rate: 192 kHz / 24-bit — captures the full frequency range with room for post-production adjustments
• A/D Dynamic Range: 120 dB — quiet sources remain clean, while louder sources avoid distortion
• Frequency Response (Mic): 20 Hz – 20 kHz ±0.06 dB — provides flat capture across the audible spectrum

USB-C Bus Power with Standalone Mode

Both data and 900 mA of power are supplied through a single USB-C cable. Standalone mode allows inputs to be routed directly to outputs without a connected computer.

• Host Connection: USB-C, USB 2.0 protocol — compatible with macOS, Windows, and iPadOS
• Bus Power: 5 V at 900 mA — operation with just one cable, without an external power supply
• Digital I/O: None (no S/PDIF, ADAT, AES/EBU, or MADI) — intentionally streamlined 2-in/2-out architecture
