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
The ProblemVRM (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.
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. As with the control room simulation, you can select between a number of listening positions to check stereo imaging and observe the effects of typical room modes on your mixes.
