Setup and Connectivity
Setting up the Scarlett 18i8 is straightforward for the most part. Simply install the included driver software and connect the interface to your computer via the USB-C port. The Scarlett interfaces are USB class compliant meaning they can work without drivers on iOS devices and some computers. However, installing the Focusrite Control software unlocks additional features and customization.
On the front panel, you get 4 combo XLR/TRS inputs with Scarlett’s natural sounding preamps for connecting mics and instruments like guitars and basses. There are also 2 dedicated instrument inputs on the front which bypass the preamps for plugging in electric guitars or basses directly.
The back panel hosts the remaining inputs and outputs including 8 line inputs on balanced TRS jacks, 8 line outputs on DB25 connectors, word clock in/out, MIDI in/out, and a stereo monitoring output. Focusrite provides the necessary breakout cables for the DB25 outputs.
Setting input levels and monitoring latency-free can be done either from the hardware controls on the interface itself or from the software control panel. Overall, despite the high I/O count, the Scarlett 18i8 is easy to set up for your specific studio workflow.
Bundled Software
Focusrite bundles the 18i8 with several software titles to add value to the package:
- Pro Tools First – Limited version of Avid’s flagship DAW
- Ableton Live Lite – Entry-level DAW for music production
- Softube Time & Tone Bundle – Guitar amp/effects plug-ins
- Focusrite Red Plug-in Suite – Focusrite Scarlett modeled plug-ins
- 2GB+ Loopmasters samples – Drum loops, instruments, vocals
- Direct Master – Online mastering service
- 3-month Splice subscription – Online sound library
While none are full versions, the software bundle gives you plenty to get started recording, producing, and mixing your music. And Pro Tools First compatibility is a nice perk for working with collaborative studios running the industry standard DAW.
Sound Quality
With its latest generation of Scarlett interfaces, Focusrite aimed to provide the best sounding Scarlett to date. Reviews generally agree they succeeded in improving on the already impressive quality of Scarlett’s class-leading converters and preamps.
The newly developed instrument inputs deliver crystal clear, noise-free connections for guitars and basses. The console-grade Scarlett preamps enable clean gain up to 60dB for powering microphones while adding pleasing warmth and character to vocals and acoustic instruments.
Distortion and noise levels are extremely low throughout, with up to 119dB dynamic range on the inputs and 118dB on the outputs. Operation is clean all the way up to 24-bit/192kHz resolution. The end result is professional grade recordings with pleasing analog character that stands up to some of the best in the price range.
Performance
Latency can make recording and monitoring a nightmare. Thankfully the 18i8 3rd Gen’s roundtrip latency is impressively low at sub-2ms, even at sizable buffer settings. This basically eliminates lag allowing you to track in real-time without phase issues or distracting delays.
The updated conversion chipset also helps maximize CPU efficiency. Even larger sessions with lots of tracks and plug-in processing should run smoothly. Phantom power is switchable in pairs for condenser mics requiring +48V. There are also plenty of LED meters to visually monitor levels on hardware.
In terms of compatibility, the 18i8 works as a class-compliant Core Audio device on macOS and iOS devices without needing the Focusrite Control software. For Windows, you’ll need to install the ASIO drivers for optimal performance. The interface worked reliably during testing across multiple devices.
Who Should Buy It?
The Focusrite Scarlett 18i8 3rd Gen suits home studios needing an ample I/O interface with excellent sound quality. Musicians with larger collections of microphones, instruments, and outboard gear will appreciate the expanded connectivity. The upgraded instrument inputs also make it ideal as a streamlined solution for guitar and bass direct input recording.
However, those wanting portability may find it a bit large and heavy for mobile use. Beginners would be fine starting with a smaller interface like the 2i2 or 4i4. And professionals needing advanced routing flexibility may want to look at higher end options like the Clarett or Red interfaces.
Pros
- Excellent audio quality
- Low-latency monitoring
- Intuitive software control
- Rugged metal construction
- Bundled recording software
Cons
- No native DAW integration
- Can be complicated for beginners
- Lacks advanced mix features of Clarett range
FAQs
How many mics can you connect?
The 18i8 has 4 mic/instrument inputs on the front, so you can connect up to 4 microphones or direct instruments simultaneously. However, with 8 additional line inputs on the back, you can use external mic preamps to add more microphones if needed.
Does it work with iOS/Android devices?
Yes, the 18i8 is class compliant meaning it will function as a plug-and-play interface when connected to iPhones/iPads or Android devices. However, you won’t get access to the Focusrite Control software features and customization on mobile devices.
What is the difference from the 2nd generation model?
The main improvements include newly developed instrument inputs, upgraded conversion for lower latency monitoring, and additional software bundle including Softube plug-ins and mastering/samples access. The overall converter quality and mic preamps have also been improved.
Can you use it without a computer connected?
No, the Scarlett 18i8 is designed to function as an audio interface requiring a USB connection to a computer or mobile device. It does not have internal mixing capabilities for standalone operation.
Does it come with XLR cables?
No, XLR cables for microphones are not included. You’ll need to provide your own microphone cables. However, all necessary cables for connecting the DB25 line outputs are included.
Conclusion
With its clean preamps, hi-res conversion, flexible routing, and rich software bundle, the Focusrite Scarlett 18i8 3rd Gen is an impressive interface for project studio owners who demand quality. It provides an accessible way to take your recordings to a higher level of professionalism.
While not as affordable as Scarlett’s 2-input models, the expanded I/O connections and bundled software make the 18i8 a considerable value at its price point. Overall, if you’re looking to create full-fledged productions with high sound quality, the Scarlett 18i8 deserves your consideration.
