🎯 Complete Scarlett 18i20 Review

🎤 Preamp Quality: Proven Scarlett Performance

The 18i20 uses the same high-quality preamps found in the beloved Scarlett 2i2, just more of them. Each of the 8 analog inputs delivers clean, transparent gain with plenty of headroom for dynamic sources like drums and loud guitar amps.

The first two inputs feature Air mode, which adds a subtle high-frequency lift that works beautifully on vocals and acoustic instruments. I typically use these inputs for lead vocals and acoustic guitars, reserving the remaining inputs for drums and electric instruments.

After recording dozens of drum kits through the 18i20, I can confirm the preamps handle everything from delicate brush work to thunderous rock performances without breaking a sweat. The noise floor is impressively low, even when pushing the gain for quieter sources.

🔧 Build Quality and Design

The 18i20 feels substantial and professional. The metal chassis and quality controls inspire confidence during long recording sessions. Unlike smaller interfaces, this unit has dedicated knobs for each input’s gain control, making adjustments quick and intuitive during sessions.

The front panel LED meters are bright and easy to read, crucial when monitoring multiple inputs simultaneously. The rear panel connectivity is well-organized with clearly labeled inputs and outputs that make complex routing straightforward.

The only drawback is size – this interface takes up significant desk real estate. However, for the functionality provided, the size is reasonable and the sturdy construction justifies the footprint.

⚡ Performance and Workflow

Driver stability matches the excellent reputation of other Scarlett interfaces. In two years of regular band recording sessions, I’ve experienced zero crashes or dropouts. The interface handles complex sessions with 16+ tracks recording simultaneously without hesitation.

Latency performance is excellent, particularly important when recording full bands where musicians need to hear themselves clearly in the mix. The direct monitoring capabilities work flawlessly, and the Focusrite Control software provides flexible routing options for creating different monitor mixes.

The USB-C connection provides reliable power and data transfer. Unlike some multi-input interfaces that require external power supplies, the 18i20 draws all necessary power from USB while maintaining professional performance.

🎛️ Connectivity and Expansion

The comprehensive I/O makes the 18i20 incredibly versatile:

  • 8 XLR/TRS combo inputs – Perfect for full band recording
  • 2 dedicated instrument inputs – High-impedance for guitars and basses
  • 10 balanced TRS outputs – Multiple monitor mixes and sends
  • ADAT optical I/O – Expand to 16+ inputs with external preamps
  • S/PDIF digital I/O – Connect digital processors or other interfaces
  • 2 independent headphone outputs – Separate mixes for performers
  • Monitor controller features – Talkback, dim, and mono switching

The ADAT expansion is particularly valuable. I’ve used it with 8-channel preamps to record orchestral sessions requiring 12+ simultaneous inputs while maintaining the same high-quality conversion throughout.

🏠 Perfect for Home Studio Band Recording

The 18i20 excels in home studios where space is limited but full band recording is essential:

  • Full band tracking – Capture the energy of live band performances
  • Drum recording – Professional results with 6-8 microphones
  • Multi-instrumentalists – Layer multiple instruments efficiently
  • Producer workflows – Multiple synthesizers and drum machines
  • Podcast/content creation – Multiple hosts and guests

  • ADAT expansion for even more inputs when needed
  • Individual gain knobs for each input – easy adjustments
  • Solid build quality with professional feel

❌ Cons

  • More expensive than smaller interfaces
  • Learning curve for complex routing features
  • No onboard effects or DSP processing
  • Monitor controller features are basic
  • Can be overwhelming for beginners

❓ Scarlett 18i20 FAQ

Absolutely. The 8 analog inputs are perfect for drum recording with 6-8 microphones. I regularly record full drum kits using kick, snare, hi-hat, two overheads, and room mics with excellent results. The preamps handle everything from delicate brushwork to thunderous rock drums.

Yes, that’s exactly what it’s designed for. A typical setup uses 4-6 inputs for drums, 1 for bass direct, 1-2 for guitar amps, and 1 for vocals. This captures the complete band performance while maintaining excellent sound quality across all sources.

Probably not. The Scarlett 2i2 offers the same preamp quality for solo recording at a much lower price. The 18i20 is best for situations where you need multiple simultaneous inputs for bands, drums, or complex multi-instrument setups.

Yes, through ADAT optical connections. You can add 8 more inputs at 48kHz using ADAT-equipped preamps, giving you 16 total analog inputs. This makes it suitable for larger orchestral or choir recordings while maintaining the same conversion quality.

The 3rd generation features improved preamps, better converters, Air mode on inputs 1-2, and USB-C connectivity. The build quality and reliability are also significantly improved. If buying new, definitely get the 3rd generation for the enhanced performance.
