VRM Box er et hendig lite USB-interface som forvandler hodetelefonene dine til studimonitorer i et perfekt lyttemiljø: -et hodetelefon USB-interface med Focusrites patenterte VRM-teknologi (Virtual Reference Monitoring).

VRM er en konvolusjonsteknologi som påfører hodetelefonsignalet crosstalk (lekkasje mellom left/right) og førsterefleksjoner (noe som påvirker frekvensresponsen). Mikser gjort på hodetelefoner kan ofte låte trange og ”boomy” når de overføres til høyttalere. Med VRM Box kan du stole på at panoreringen er vid nok, bassresponsen balansert og toppen luftig. Du kan også velge mellom ulike studiomonitorer (kun kjente merker), lyttemiljøer (kontrollrom, stue og soverom), samt endre lytteposisjon.

Focusrite VRM-Box strømforsynes via USB. Den har også S/PDIF inn, slik at den kan brukes som stand alone. For optimalt resultat anbefaler vi frekvensflate hodetelefoner.

VRM Box er perfekt for alle som av og til er tvunget til å mikse på hodetelefoner. Den er også et ypperlig alternativ til billige studiomonitorer og/eller dårlige akustiske forhold. Til slutt er det en enkel og billig måte å oppgradere din PC/macs standard hodetelefonutgang.

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.

Virtual Reference Monitoring
 
The Problem
VRM (Virtual Reference Monitoring) is Focusrite’s own loudspeaker & room simulator designed for headphone listening. Accurate mixing has until now, required expensive monitors and a carefully designed and treated control room. Currently, both professional music producers facing budgetary limitations and project music makers without access to such, frequently encounter mixing and "auditioning" difficulties.

The Solution
VRM allows you to choose from 10 pairs of industry standard nearfield and main monitors in an acoustically treated control room. 
 
Engineers routinely A/B their mixes by burning CDs and taking them into untreated rooms to reference on consumer stereos. VRM eliminates this process by simulating two extra rooms; a large living room and a smaller bedroom. You can choose between a range of speakers including quality hi-fi, computer, cheap stereo and television speakers.
