Hands-On Review: Focusrite VRM Box


The VRM Box from Focusrite is a unique USB computer audio interface that’s solely dedicated to headphone monitoring. It enables you to listen to mixes on your computer with 15 different sets of emulated studio monitors, featuring everything from Genelec 1031A’s and Yamaha NS10’s to the built-in speakers on a flat-panel television. The included Mac and PC compatible software also lets you change the emulation of the room that you’re listening in, from the control room of a professional studio, to a typical bedroom project studio and an average living room. The VRM box is a great way to hear how your sound translates to different speakers and listening environments, without taking off your headphones. Obviously, it’s not as ideal as actually having access to multiple physical speakers and rooms, but it makes a fantastic portable solution for mixing in the field. To get a better idea of what the VRM Box can do, check out our hands-on review video below.
