Computer system requirements:
Below are the minimum computer-system requirements for the AudioBox 1818VSL:
Windows
- Windows® 7x 64/x86 SP1 or Windows 8/8.1 x64/x86 or Windows 10 x64/x86
- Intel® Core™ 2 processor (Intel® Core™ i3 processor or better recommended)
- 4 GB RAM (8 GB or more recommended)
Mac
- macOS® 10.11 or higher (64-bit only)*
- Intel Core Duo processor (Intel Core 2 Duo or Intel Core i3 or better recommended)
- 2 GB RAM (4 GB or more recommended)
Windows and Mac Systems
- USB 2.0 Port
- Internet connection (only for activation)
- DVD-ROM drive
- Monitor with at least 1024x768 resolution
- 20 GB hard-disk space
- Internal or external 7200 RPM storage drive highly recommended
* Please Note: Starting with OS X 10.11, Apple has restricted kernel level mixing access for third party vendors. This means that the included VSL software will no longer function on Mac operating systems beyond version 10.10. On OS X version 10.11 or higher, AudioBox VSL devices will only operate as low-latency, class-complaint audio interfaces.
The minimum system requirements may differ for DAWs other than Studio One. Please check the requirements for your DAW of choice with its manufacturer.
Note that the speed of your processor, amount of RAM and size and speed of your hard drive will greatly affect the overall performance of your recording system. Also, a more powerful system (faster processor with more RAM) will allow for lower latency (signal delay) than you might experience while monitoring audio or MIDI signals. Monitor resolution for both PC and Macintosh should be no lower than 1024x768 pixels.
