The VRM Box from Focusrite is a headphone monitoring/mixing solution that allows you mix in your studio, wherever you are and with any pair of headphones. The system consists of a robust, pocket sized audio interface partnered with the company's Virtual Reference Monitoring (VRM) software, allowing you to mix anytime, anywhere.

VRM Box functions as a high-quality 24-bit/48kHz USB audio playback interface. It features an S/PDIF input for connecting to your audio interface and delivers high quality, low distortion audio at the headphone output. It allows for monitoring or mixing when it is impractical to use speakers, especially late at night.

The VRM software overcomes the major obstacle of mixing with headphones by providing multiple perspectives on your mix, as if listening through speakers in different environments. It lets you choose from a living room, a bedroom studio, or a professional studio, along with a choice of industry-standard studio monitors and speakers.

The system uses standard headphones to reproduce the direct sound, together with a "Direct FX" DSP system to simulate specific monitoring scenarios. The range of speakers includes quality hi-fi, computer, and cheap stereo and television speakers. The control room simulation allows you to select between a number of listening positions to check stereo imaging and observe the effects of typical room modes on your mixes.

The loudspeaker simulations are created using convolutions of impulse responses measured using the original loudspeakers. The interface is USB bus powered, making it eminently portable. So, whether you're mixing, creating music or simply listening to tracks, VRM Box is a perfect headphone monitoring solution.
