Focusrite Audio Engineering VRM Box

With VRM Box, you can mix in your studio, wherever you are. Pocket sized and built to last, VRM Box places Focusrite’s proven and patent-pending VRM – Virtual Reference Monitoring – technology in a robust, palm-sized audio interface.

VRM overcomes the major obstacle for mixing with headphones by giving you multiple perspectives on your mix, as if you were listening through speakers. Indeed, noise levels from mixing through speakers can make it impossible for most to mix at home, especially late at night; with VRM, you can mix any time, anywhere. Using any pair of monitoring headphones, VRM lets you choose your mixing environment from a living room, a bedroom studio, or a professional studio. You then simply choose from a list of industry-standard studio monitors and speakers

VRM Box delivers audio quality worthy of your headphones. Boasting a dynamic range of 108dB, it provides a sound that’s more precise, with lower distortion, than other low-cost audio interfaces, and far superior to built-in laptop headphone outputs.

VRM Box functions as a high-quality 24- bit/48kHz USB audio playback interface. So, whether you're mixing, creating music or simply listening to tracks, VRM Box is perfect. What’s more, there’s no need for a power supply or batteries, because it gets all the power it needs, with full audio quality, from your computer’s USB port. VRM Box also features a digital (S/PDIF) input, which supports sample rates up to 192kHz. This allows you to run it in conjunction with your Pro Tools HD system, or any other interface with an S/PDIF output.

Mix in your studio, wherever you are.
Focusrite’s patent-pending and proven VRM – Virtual Reference Monitoring – technology, lets hear your mix in different environments, through different speakers and from different positions, just using headphones. Enhanced mathematical room models combine with speaker emulations, sampled using a unique dynamic convolution ‘sampling’ process.

Make the most of your headphones
With a dynamic range of 108dB (A-weighted), VRM Box provides a significant audio upgrade from low-grade laptop headphone outputs (which commonly only provide around 92 or 93dB), with an audio quality the equal of interfaces ten times its price.

Pocket sized and built to last
The compact size and robust build quality of VRM Box means it’s ready to go anywhere, any time.

Pro Tools Native and HD friendly
VRM Box features a digital input, allowing you to run it alongside your Pro Tools HD interface, or any interface
