The Focusrite VRM Box functions as a high-quality 24-bit/48kHz USB audio playback 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.
Features
:
Three virtual rooms and 15 virtual speakers
Monitor in a virtual professional studio, living room or bedroom. With 15 different speaker models, you get multiple perspectives on your mix. From the Genelec 1031A, to the KRK VXT8 and the BBC-designed LS3-5a, we have meticulously measured each of the speakers to bring their characteristics to your headphones. There’s even an LCD television to use for reference!
Use alongside any interface
VRM Box can be used in conjunction with any interface that has an S/PDIF output, including Pro Tools HD and Pro Tools HD Native. This makes switching between VRM headphone monitoring and speaker monitoring painless. VRM Box can receive S/PDIF signals at any standard sampling frequency (44.1 to 192 KHz) meaning you don't need to change your session setup – just route your mix to the S/PDIF out.
High-quality monitoring anywhere
Sometimes it’s not possible to take your interface with you, as it’s too large or because it’s wired into your studio. The portable format of VRM Box allows you to take it anywhere – just sling it in your laptop bag and be safe in the knowledge that its robust case will stand up to the rigors of the road. It’s even bus powered so all you need is the USB cable.
A great upgrade for headphone listening
If you like to listen to music on your computer with headphones, VRM Box provides a great improvement when compared with on-board sound and indeed many other audio interfaces. With a dynamic range of 108 dBA and very low noise and distortion figures, VRM Box delivers pristine sound with or without the optional room and speaker modelling.
Science of VRM
:
The Problem
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.
The Method
VRM Box uses standard headphones to reproduce the direct sound, together with software running on your computer that is used to simulate specific monitoring scenarios. VRM's room models are mathematical models which provide greater flexibility in the possible combinations of loudspeakers. The loudspeaker simulations are created using convolutions of impulse responses measured using the original loudspeakers. The accuracy of these simulations in different environments is taken care of by the impulse responses themselves and the way they are calculated and manipulated.
