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.
