Steinberg UR22C USB Audio Interface — Studio Sound in a Compact Body

The Steinberg UR22C is a 2-in/2-out USB 3.1 audio interface built around Yamaha D-PRE Class-A preamps and 32-bit/192 kHz converters. It connects to Mac, Windows, or iOS via USB-C and runs on bus power. The full-metal chassis weighs 1 kg, ready for travel between home studio and live location.

What Sets This Interface Apart

Two D-PRE preamps deliver transparent, detailed sound with tight low end and extended highs. The onboard SSP3 DSP chip powers zero-latency monitoring through dspMixFx, running REV-X reverb, the Sweet Spot Morphing Channel Strip, and Guitar Amp Classics inside the unit. A Loopback function merges mic input with DAW playback for direct live streaming without extra routing software.

Inputs, Outputs, and Host Connection

The interface keeps I/O focused on what a mobile recordist actually uses, with no S/PDIF, ADAT, or AES/EBU expansion ports on the rear.

• Number of Channels: 2 in / 2 out — covers a vocal-plus-guitar session without extra gear
• Inputs: 2 × XLR-Jack combo (1 with Hi-Z), MIDI IN — mic, line, instrument, and MIDI in one box
• Outputs: 2 × 6.3 mm TRS, headphone 6.3 mm TRS, MIDI OUT, USB-C — drives monitors, headphones, and MIDI gear from a single rear panel

Audio Resolution and Preamp Performance

This model delivers 32-bit AD/DA at sample rates up to 192 kHz, capturing detail well above the audible range for later pitch and time processing.

• Sample Rate: up to 192 kHz — captures ultrasonic detail for creative post-production
• Bit Depth: 32-bit — preserves full dynamic range without quantization noise
• Number of Preamps: 2 × D-PRE Class-A — Yamaha discrete design with detailed highs and rounded lows
• Phantom Power: +48 V on both XLR inputs — runs any studio condenser microphone
• Dynamic Range: 102 dB (A-weighted) — measured headroom for clean vocal and instrument capture

Onboard Effects, Monitoring, and Physical Design

The SSP3 DSP runs REV-X reverb, the Sweet Spot Morphing Channel Strip, and Guitar Amp Classics with direct-monitoring latency around 115 microseconds, fast enough for real-time performance.

• Onboard DSP: SSP3 with dspMixFx — runs effects without loading the host CPU
• Headphone Output: 6.3 mm TRS with dedicated volume control — drives higher-impedance studio headphones
• Power: USB-C bus-powered, micro-USB fallback — works from laptop or iPad without an external adaptor
• Dimensions: 159 × 159 × 47 mm, 1 kg — fits any mobile rig
