Focusrite SCARLETT4i4-4G 4th Generation USB Audio Interface

The Focusrite SCARLETT4i4-4G 4th Generation serves as a 4-in/4-out USB-C audio interface tailored for multi-instrumentalists and small studios. It brings together two ultra-low-noise preamps, Hi-Z inputs, line I/O, and 5-pin MIDI in a bus-powered desktop format. Studio-grade 24-bit/192 kHz conversion, drawn from flagship RedNet interfaces, is accompanied by Air Mode, Auto Gain, Clip Safe, and Loopback to support tracking, monitoring, and streaming.

Distinctive Features of the SCARLETT4i4-4G

Inside the unit are Cirrus Logic CS5381 A/D and CS43198 D/A converters from the RedNet family. Clip Safe monitors levels up to 96,000 times per second and automatically adjusts preamp gain, preventing clipping during takes. With two Air Mode options—Presence for high-end sparkle and Presence + Drive for classic console-like harmonic saturation—users shape their sound to taste.

Preamp and Input Versatility

Two front-panel combo inputs accept XLR microphones, balanced line sources, or Hi-Z instruments, eliminating the need for a DI box. Each preamp delivers up to 69 dB of clean gain with an EIN of -127 dBu A-Weighted, and 48V phantom power is independently selectable per channel.

• Microphone Preamps: 2 — adjustable remotely via Focusrite Control 2 software
• Mic/line inputs offer a gain range of 69 dB, while Hi-Z instrument inputs provide 62 dB, supporting a wide range of sources.
• Phantom Power: 48 V per channel — compatible with condenser microphones

High-Quality Conversion and Digital Handling

Audio is captured and played back at up to 24-bit/192 kHz. The D/A conversion ensures a dynamic range of 120 dB, enabling transparent monitoring across macOS, Windows, and iPadOS via USB-C at sample rates from 44.1 kHz to 192 kHz.

• Maximum Sample Rate: 192 kHz / 24-bit
• With a D/A dynamic range of 120 dB, monitoring headroom is comparable to flagship RedNet converters.

Connectivity, Outputs, and Design

Four balanced 1/4" TRS line outputs allow for two independent monitor mixes or outboard routing. The custom headphone amplifier handles high-impedance headphones, and 5-pin MIDI I/O integrates external hardware controllers.

• Host Connection: USB-C, USB 2.0 protocol — bus-powered at 1.5 A
• Line Outputs: 4x 1/4" TRS balanced — each output can carry a separate mix
• MIDI I/O: 5-pin DIN In and Out — supports hardware controllers and synthesizers
